+
+Implement tasks from an OpenSpec change.
+
+**Input**: Optionally specify a change name (e.g., `/opsx:apply add-auth`). If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
+
+**Steps**
+
+1. **Select the change**
+
+   If a name is provided, use it. Otherwise:
+   - Infer from conversation context if the user mentioned a change
+   - Auto-select if only one active change exists
+   - If ambiguous, run `openspec list --json` to get available changes and use the **AskUserQuestion tool** to let the user select
+
+   Always announce: "Using change: <name>" and how to override (e.g., `/opsx:apply <other>`).
+
+2. **Check status to understand the schema**
+   ```bash
+   openspec status --change "<name>" --json
+   ```
+   Parse the JSON to understand:
+   - `schemaName`: The workflow being used (e.g., "spec-driven")
+   - Which artifact contains the tasks (typically "tasks" for spec-driven, check status for others)
+
+3. **Get apply instructions**
+
+   ```bash
+   openspec instructions apply --change "<name>" --json
+   ```
+
+   This returns:
+   - Context file paths (varies by schema)
+   - Progress (total, complete, remaining)
+   - Task list with status
+   - Dynamic instruction based on current state
+
+   **Handle states:**
+   - If `state: "blocked"` (missing artifacts): show message, suggest using `/opsx:continue`
+   - If `state: "all_done"`: congratulate, suggest archive
+   - Otherwise: proceed to implementation
+
+4. **Read context files**
+
+   Read the files listed in `contextFiles` from the apply instructions output.
+   The files depend on the schema being used:
+   - **spec-driven**: proposal, specs, design, tasks
+   - Other schemas: follow the contextFiles from CLI output
+
+5. **Show current progress**
+
+   Display:
+   - Schema being used
+   - Progress: "N/M tasks complete"
+   - Remaining tasks overview
+   - Dynamic instruction from CLI
+
+6. **Implement tasks (loop until done or blocked)**
+
+   For each pending task:
+   - Show which task is being worked on
+   - Make the code changes required
+   - Keep changes minimal and focused
+   - Mark task complete in the tasks file: `- [ ]` → `- [x]`
+   - Continue to next task
+
+   **Pause if:**
+   - Task is unclear → ask for clarification
+   - Implementation reveals a design issue → suggest updating artifacts
+   - Error or blocker encountered → report and wait for guidance
+   - User interrupts
+
+7. **On completion or pause, show status**
+
+   Display:
+   - Tasks completed this session
+   - Overall progress: "N/M tasks complete"
+   - If all done: suggest archive
+   - If paused: explain why and wait for guidance
+
+**Output During Implementation**
+
+```
+## Implementing: <change-name> (schema: <schema-name>)
+
+Working on task 3/7: <task description>
+[...implementation happening...]
+✓ Task complete
+
+Working on task 4/7: <task description>
+[...implementation happening...]
+✓ Task complete
+```
+
+**Output On Completion**
+
+```
+## Implementation Complete
+
+**Change:** <change-name>
+**Schema:** <schema-name>
+**Progress:** 7/7 tasks complete ✓
+
+### Completed This Session
+- [x] Task 1
+- [x] Task 2
+...
+
+All tasks complete! You can archive this change with `/opsx:archive`.
+```
+
+**Output On Pause (Issue Encountered)**
+
+```
+## Implementation Paused
+
+**Change:** <change-name>
+**Schema:** <schema-name>
+**Progress:** 4/7 tasks complete
+
+### Issue Encountered
+<description of the issue>
+
+**Options:**
+1. <option 1>
+2. <option 2>
+3. Other approach
+
+What would you like to do?
+```
+
+**Guardrails**
+- Keep going through tasks until done or blocked
+- Always read context files before starting (from the apply instructions output)
+- If task is ambiguous, pause and ask before implementing
+- If implementation reveals issues, pause and suggest artifact updates
+- Keep code changes minimal and scoped to each task
+- Update task checkbox immediately after completing each task
+- Pause on errors, blockers, or unclear requirements - don't guess
+- Use contextFiles from CLI output, don't assume specific file names
+
+**Fluid Workflow Integration**
+
+This skill supports the "actions on a change" model:
+
+- **Can be invoked anytime**: Before all artifacts are done (if tasks exist), after partial implementation, interleaved with other actions
+- **Allows artifact updates**: If implementation reveals design issues, suggest updating artifacts - not phase-locked, work fluidly

+
+Archive a completed change in the experimental workflow.
+
+**Input**: Optionally specify a change name after `/opsx:archive` (e.g., `/opsx:archive add-auth`). If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
+
+**Steps**
+
+1. **If no change name provided, prompt for selection**
+
+   Run `openspec list --json` to get available changes. Use the **AskUserQuestion tool** to let the user select.
+
+   Show only active changes (not already archived).
+   Include the schema used for each change if available.
+
+   **IMPORTANT**: Do NOT guess or auto-select a change. Always let the user choose.
+
+2. **Check artifact completion status**
+
+   Run `openspec status --change "<name>" --json` to check artifact completion.
+
+   Parse the JSON to understand:
+   - `schemaName`: The workflow being used
+   - `artifacts`: List of artifacts with their status (`done` or other)
+
+   **If any artifacts are not `done`:**
+   - Display warning listing incomplete artifacts
+   - Prompt user for confirmation to continue
+   - Proceed if user confirms
+
+3. **Check task completion status**
+
+   Read the tasks file (typically `tasks.md`) to check for incomplete tasks.
+
+   Count tasks marked with `- [ ]` (incomplete) vs `- [x]` (complete).
+
+   **If incomplete tasks found:**
+   - Display warning showing count of incomplete tasks
+   - Prompt user for confirmation to continue
+   - Proceed if user confirms
+
+   **If no tasks file exists:** Proceed without task-related warning.
+
+4. **Assess delta spec sync state**
+
+   Check for delta specs at `openspec/changes/<name>/specs/`. If none exist, proceed without sync prompt.
+
+   **If delta specs exist:**
+   - Compare each delta spec with its corresponding main spec at `openspec/specs/<capability>/spec.md`
+   - Determine what changes would be applied (adds, modifications, removals, renames)
+   - Show a combined summary before prompting
+
+   **Prompt options:**
+   - If changes needed: "Sync now (recommended)", "Archive without syncing"
+   - If already synced: "Archive now", "Sync anyway", "Cancel"
+
+   If user chooses sync, use Task tool (subagent_type: "general-purpose", prompt: "Use Skill tool to invoke openspec-sync-specs for change '<name>'. Delta spec analysis: <include the analyzed delta spec summary>"). Proceed to archive regardless of choice.
+
+5. **Perform the archive**
+
+   Create the archive directory if it doesn't exist:
+   ```bash
+   mkdir -p openspec/changes/archive
+   ```
+
+   Generate target name using current date: `YYYY-MM-DD-<change-name>`
+
+   **Check if target already exists:**
+   - If yes: Fail with error, suggest renaming existing archive or using different date
+   - If no: Move the change directory to archive
+
+   ```bash
+   mv openspec/changes/<name> openspec/changes/archive/YYYY-MM-DD-<name>
+   ```
+
+6. **Display summary**
+
+   Show archive completion summary including:
+   - Change name
+   - Schema that was used
+   - Archive location
+   - Spec sync status (synced / sync skipped / no delta specs)
+   - Note about any warnings (incomplete artifacts/tasks)
+
+**Output On Success**
+
+```
+## Archive Complete
+
+**Change:** <change-name>
+**Schema:** <schema-name>
+**Archived to:** openspec/changes/archive/YYYY-MM-DD-<name>/
+**Specs:** ✓ Synced to main specs
+
+All artifacts complete. All tasks complete.
+```
+
+**Output On Success (No Delta Specs)**
+
+```
+## Archive Complete
+
+**Change:** <change-name>
+**Schema:** <schema-name>
+**Archived to:** openspec/changes/archive/YYYY-MM-DD-<name>/
+**Specs:** No delta specs
+
+All artifacts complete. All tasks complete.
+```
+
+**Output On Success With Warnings**
+
+```
+## Archive Complete (with warnings)
+
+**Change:** <change-name>
+**Schema:** <schema-name>
+**Archived to:** openspec/changes/archive/YYYY-MM-DD-<name>/
+**Specs:** Sync skipped (user chose to skip)
+
+**Warnings:**
+- Archived with 2 incomplete artifacts
+- Archived with 3 incomplete tasks
+- Delta spec sync was skipped (user chose to skip)
+
+Review the archive if this was not intentional.
+```
+
+**Output On Error (Archive Exists)**
+
+```
+## Archive Failed
+
+**Change:** <change-name>
+**Target:** openspec/changes/archive/YYYY-MM-DD-<name>/
+
+Target archive directory already exists.
+
+**Options:**
+1. Rename the existing archive
+2. Delete the existing archive if it's a duplicate
+3. Wait until a different date to archive
+```
+
+**Guardrails**
+- Always prompt for change selection if not provided
+- Use artifact graph (openspec status --json) for completion checking
+- Don't block archive on warnings - just inform and confirm
+- Preserve .openspec.yaml when moving to archive (it moves with the directory)
+- Show clear summary of what happened
+- If sync is requested, use the Skill tool to invoke `openspec-sync-specs` (agent-driven)
+- If delta specs exist, always run the sync assessment and show the combined summary before prompting

+
+Enter explore mode. Think deeply. Visualize freely. Follow the conversation wherever it goes.
+
+**IMPORTANT: Explore mode is for thinking, not implementing.** You may read files, search code, and investigate the codebase, but you must NEVER write code or implement features. If the user asks you to implement something, remind them to exit explore mode first and create a change proposal. You MAY create OpenSpec artifacts (proposals, designs, specs) if the user asks—that's capturing thinking, not implementing.
+
+**This is a stance, not a workflow.** There are no fixed steps, no required sequence, no mandatory outputs. You're a thinking partner helping the user explore.
+
+**Input**: The argument after `/opsx:explore` is whatever the user wants to think about. Could be:
+- A vague idea: "real-time collaboration"
+- A specific problem: "the auth system is getting unwieldy"
+- A change name: "add-dark-mode" (to explore in context of that change)
+- A comparison: "postgres vs sqlite for this"
+- Nothing (just enter explore mode)
+
+---
+
+## The Stance
+
+- **Curious, not prescriptive** - Ask questions that emerge naturally, don't follow a script
+- **Open threads, not interrogations** - Surface multiple interesting directions and let the user follow what resonates. Don't funnel them through a single path of questions.
+- **Visual** - Use ASCII diagrams liberally when they'd help clarify thinking
+- **Adaptive** - Follow interesting threads, pivot when new information emerges
+- **Patient** - Don't rush to conclusions, let the shape of the problem emerge
+- **Grounded** - Explore the actual codebase when relevant, don't just theorize
+
+---
+
+## What You Might Do
+
+Depending on what the user brings, you might:
+
+**Explore the problem space**
+- Ask clarifying questions that emerge from what they said
+- Challenge assumptions
+- Reframe the problem
+- Find analogies
+
+**Investigate the codebase**
+- Map existing architecture relevant to the discussion
+- Find integration points
+- Identify patterns already in use
+- Surface hidden complexity
+
+**Compare options**
+- Brainstorm multiple approaches
+- Build comparison tables
+- Sketch tradeoffs
+- Recommend a path (if asked)
+
+**Visualize**

+
+## OpenSpec Awareness
+
+You have full context of the OpenSpec system. Use it naturally, don't force it.
+
+### Check for context
+
+At the start, quickly check what exists:
+```bash
+openspec list --json
+```
+
+This tells you:
+- If there are active changes
+- Their names, schemas, and status
+- What the user might be working on
+
+If the user mentioned a specific change name, read its artifacts for context.
+
+### When no change exists
+
+Think freely. When insights crystallize, you might offer:
+
+- "This feels solid enough to start a change. Want me to create a proposal?"
+- Or keep exploring - no pressure to formalize
+
+### When a change exists
+
+If the user mentions a change or you detect one is relevant:
+
+1. **Read existing artifacts for context**
+   - `openspec/changes/<name>/proposal.md`
+   - `openspec/changes/<name>/design.md`
+   - `openspec/changes/<name>/tasks.md`
+   - etc.
+
+2. **Reference them naturally in conversation**
+   - "Your design mentions using Redis, but we just realized SQLite fits better..."
+   - "The proposal scopes this to premium users, but we're now thinking everyone..."
+
+3. **Offer to capture when decisions are made**
+
+   | Insight Type | Where to Capture |
+   |--------------|------------------|
+   | New requirement discovered | `specs/<capability>/spec.md` |
+   | Requirement changed | `specs/<capability>/spec.md` |
+   | Design decision made | `design.md` |
+   | Scope changed | `proposal.md` |
+   | New work identified | `tasks.md` |
+   | Assumption invalidated | Relevant artifact |
+
+   Example offers:
+   - "That's a design decision. Capture it in design.md?"
+   - "This is a new requirement. Add it to specs?"
+   - "This changes scope. Update the proposal?"
+
+4. **The user decides** - Offer and move on. Don't pressure. Don't auto-capture.
+
+---
+
+## What You Don't Have To Do
+
+- Follow a script
+- Ask the same questions every time
+- Produce a specific artifact
+- Reach a conclusion
+- Stay on topic if a tangent is valuable
+- Be brief (this is thinking time)
+
+---
+
+## Ending Discovery
+
+There's no required ending. Discovery might:
+
+- **Flow into a proposal**: "Ready to start? I can create a change proposal."
+- **Result in artifact updates**: "Updated design.md with these decisions"
+- **Just provide clarity**: User has what they need, moves on
+- **Continue later**: "We can pick this up anytime"
+
+When things crystallize, you might offer a summary - but it's optional. Sometimes the thinking IS the value.
+
+---
+
+## Guardrails
+
+- **Don't implement** - Never write code or implement features. Creating OpenSpec artifacts is fine, writing application code is not.
+- **Don't fake understanding** - If something is unclear, dig deeper
+- **Don't rush** - Discovery is thinking time, not task time
+- **Don't force structure** - Let patterns emerge naturally
+- **Don't auto-capture** - Offer to save insights, don't just do it
+- **Do visualize** - A good diagram is worth many paragraphs
+- **Do explore the codebase** - Ground discussions in reality
+- **Do question assumptions** - Including the user's and your own

+- proposal.md (what & why)
+- design.md (how)
+- tasks.md (implementation steps)
+
+When ready to implement, run /opsx:apply
+
+---
+
+**Input**: The argument after `/opsx:propose` is the change name (kebab-case), OR a description of what the user wants to build.
+
+**Steps**
+
+1. **If no input provided, ask what they want to build**
+
+   Use the **AskUserQuestion tool** (open-ended, no preset options) to ask:
+   > "What change do you want to work on? Describe what you want to build or fix."
+
+   From their description, derive a kebab-case name (e.g., "add user authentication" → `add-user-auth`).
+
+   **IMPORTANT**: Do NOT proceed without understanding what the user wants to build.
+
+2. **Create the change directory**
+   ```bash
+   openspec new change "<name>"
+   ```
+   This creates a scaffolded change at `openspec/changes/<name>/` with `.openspec.yaml`.
+
+3. **Get the artifact build order**
+   ```bash
+   openspec status --change "<name>" --json
+   ```
+   Parse the JSON to get:
+   - `applyRequires`: array of artifact IDs needed before implementation (e.g., `["tasks"]`)
+   - `artifacts`: list of all artifacts with their status and dependencies
+
+4. **Create artifacts in sequence until apply-ready**
+
+   Use the **TodoWrite tool** to track progress through the artifacts.
+
+   Loop through artifacts in dependency order (artifacts with no pending dependencies first):
+
+   a. **For each artifact that is `ready` (dependencies satisfied)**:
+      - Get instructions:
+        ```bash
+        openspec instructions <artifact-id> --change "<name>" --json
+        ```
+      - The instructions JSON includes:
+        - `context`: Project background (constraints for you - do NOT include in output)
+        - `rules`: Artifact-specific rules (constraints for you - do NOT include in output)
+        - `template`: The structure to use for your output file
+        - `instruction`: Schema-specific guidance for this artifact type
+        - `outputPath`: Where to write the artifact
+        - `dependencies`: Completed artifacts to read for context
+      - Read any completed dependency files for context
+      - Create the artifact file using `template` as the structure
+      - Apply `context` and `rules` as constraints - but do NOT copy them into the file
+      - Show brief progress: "Created <artifact-id>"
+
+   b. **Continue until all `applyRequires` artifacts are complete**
+      - After creating each artifact, re-run `openspec status --change "<name>" --json`
+      - Check if every artifact ID in `applyRequires` has `status: "done"` in the artifacts array
+      - Stop when all `applyRequires` artifacts are done
+
+   c. **If an artifact requires user input** (unclear context):
+      - Use **AskUserQuestion tool** to clarify
+      - Then continue with creation
+
+5. **Show final status**
+   ```bash
+   openspec status --change "<name>"
+   ```
+
+**Output**
+
+After completing all artifacts, summarize:
+- Change name and location
+- List of artifacts created with brief descriptions
+- What's ready: "All artifacts created! Ready for implementation."
+- Prompt: "Run `/opsx:apply` to start implementing."
+
+**Artifact Creation Guidelines**
+
+- Follow the `instruction` field from `openspec instructions` for each artifact type
+- The schema defines what each artifact should contain - follow it
+- Read dependency artifacts for context before creating new ones
+- Use `template` as the structure for your output file - fill in its sections
+- **IMPORTANT**: `context` and `rules` are constraints for YOU, not content for the file
+  - Do NOT copy `<context>`, `<rules>`, `<project_context>` blocks into the artifact
+  - These guide what you write, but should never appear in the output
+
+**Guardrails**
+- Create ALL artifacts needed for implementation (as defined by schema's `apply.requires`)
+- Always read dependency artifacts before creating a new one
+- If context is critically unclear, ask the user - but prefer making reasonable decisions to keep momentum
+- If a change with that name already exists, ask if user wants to continue it or create a new one
+- Verify each artifact file exists after writing before proceeding to next

+
+Implement tasks from an OpenSpec change.
+
+**Input**: Optionally specify a change name. If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
+
+**Steps**
+
+1. **Select the change**
+
+   If a name is provided, use it. Otherwise:
+   - Infer from conversation context if the user mentioned a change
+   - Auto-select if only one active change exists
+   - If ambiguous, run `openspec list --json` to get available changes and use the **AskUserQuestion tool** to let the user select
+
+   Always announce: "Using change: <name>" and how to override (e.g., `/opsx:apply <other>`).
+
+2. **Check status to understand the schema**
+   ```bash
+   openspec status --change "<name>" --json
+   ```
+   Parse the JSON to understand:
+   - `schemaName`: The workflow being used (e.g., "spec-driven")
+   - Which artifact contains the tasks (typically "tasks" for spec-driven, check status for others)
+
+3. **Get apply instructions**
+
+   ```bash
+   openspec instructions apply --change "<name>" --json

+   - If `state: "all_done"`: congratulate, suggest archive
+   - Otherwise: proceed to implementation
+
+4. **Read context files**
+
+   Read the files listed in `contextFiles` from the apply instructions output.

+
+   For each pending task:
+   - Show which task is being worked on
+   - Make the code changes required
+   - Keep changes minimal and focused
+   - Mark task complete in the tasks file: `- [ ]` → `- [x]`
+   - Continue to next task

+**Fluid Workflow Integration**
+
+This skill supports the "actions on a change" model:
+
+- **Can be invoked anytime**: Before all artifacts are done (if tasks exist), after partial implementation, interleaved with other actions
+- **Allows artifact updates**: If implementation reveals design issues, suggest updating artifacts - not phase-locked, work fluidly

+
+Archive a completed change in the experimental workflow.
+
+**Input**: Optionally specify a change name. If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
+
+**Steps**
+
+1. **If no change name provided, prompt for selection**
+
+   Run `openspec list --json` to get available changes. Use the **AskUserQuestion tool** to let the user select.
+
+   Show only active changes (not already archived).
+   Include the schema used for each change if available.
+
+   **IMPORTANT**: Do NOT guess or auto-select a change. Always let the user choose.
+
+2. **Check artifact completion status**
+
+   Run `openspec status --change "<name>" --json` to check artifact completion.
+
+   Parse the JSON to understand:
+   - `schemaName`: The workflow being used
+   - `artifacts`: List of artifacts with their status (`done` or other)
+
+   **If any artifacts are not `done`:**
+   - Display warning listing incomplete artifacts
+   - Use **AskUserQuestion tool** to confirm user wants to proceed
+   - Proceed if user confirms
+
+3. **Check task completion status**
+
+   Read the tasks file (typically `tasks.md`) to check for incomplete tasks.
+
+   Count tasks marked with `- [ ]` (incomplete) vs `- [x]` (complete).
+
+   **If incomplete tasks found:**
+   - Display warning showing count of incomplete tasks
+   - Use **AskUserQuestion tool** to confirm user wants to proceed
+   - Proceed if user confirms
+
+   **If no tasks file exists:** Proceed without task-related warning.
+
+4. **Assess delta spec sync state**
+
+   Check for delta specs at `openspec/changes/<name>/specs/`. If none exist, proceed without sync prompt.
+
+   **If delta specs exist:**
+   - Compare each delta spec with its corresponding main spec at `openspec/specs/<capability>/spec.md`
+   - Determine what changes would be applied (adds, modifications, removals, renames)
+   - Show a combined summary before prompting
+
+   **Prompt options:**
+   - If changes needed: "Sync now (recommended)", "Archive without syncing"
+   - If already synced: "Archive now", "Sync anyway", "Cancel"
+
+   If user chooses sync, use Task tool (subagent_type: "general-purpose", prompt: "Use Skill tool to invoke openspec-sync-specs for change '<name>'. Delta spec analysis: <include the analyzed delta spec summary>"). Proceed to archive regardless of choice.
+
+5. **Perform the archive**
+
+   Create the archive directory if it doesn't exist:
+   ```bash
+   mkdir -p openspec/changes/archive
+   ```
+
+   Generate target name using current date: `YYYY-MM-DD-<change-name>`
+
+   **Check if target already exists:**
+   - If yes: Fail with error, suggest renaming existing archive or using different date
+   - If no: Move the change directory to archive
+
+   ```bash
+   mv openspec/changes/<name> openspec/changes/archive/YYYY-MM-DD-<name>
+   ```
+
+6. **Display summary**
+
+   Show archive completion summary including:
+   - Change name
+   - Schema that was used
+   - Archive location
+   - Whether specs were synced (if applicable)
+   - Note about any warnings (incomplete artifacts/tasks)
+
+**Output On Success**
+
+```
+## Archive Complete
+
+**Change:** <change-name>
+**Schema:** <schema-name>
+**Archived to:** openspec/changes/archive/YYYY-MM-DD-<name>/
+**Specs:** ✓ Synced to main specs (or "No delta specs" or "Sync skipped")
+
+All artifacts complete. All tasks complete.
+```
+
+**Guardrails**
+- Always prompt for change selection if not provided
+- Use artifact graph (openspec status --json) for completion checking
+- Don't block archive on warnings - just inform and confirm
+- Preserve .openspec.yaml when moving to archive (it moves with the directory)
+- Show clear summary of what happened
+- If sync is requested, use openspec-sync-specs approach (agent-driven)
+- If delta specs exist, always run the sync assessment and show the combined summary before prompting

+description: Enter explore mode - a thinking partner for exploring ideas, investigating problems, and clarifying requirements. Use when the user wants to think through something before or during a change.

+compatibility: Requires openspec CLI.
+metadata:
+  author: openspec
+  version: "1.0"

+---
+
+Enter explore mode. Think deeply. Visualize freely. Follow the conversation wherever it goes.
+
+**IMPORTANT: Explore mode is for thinking, not implementing.** You may read files, search code, and investigate the codebase, but you must NEVER write code or implement features. If the user asks you to implement something, remind them to exit explore mode first and create a change proposal. You MAY create OpenSpec artifacts (proposals, designs, specs) if the user asks—that's capturing thinking, not implementing.
+
+**This is a stance, not a workflow.** There are no fixed steps, no required sequence, no mandatory outputs. You're a thinking partner helping the user explore.
+
+---
+
+## The Stance
+
+- **Curious, not prescriptive** - Ask questions that emerge naturally, don't follow a script
+- **Open threads, not interrogations** - Surface multiple interesting directions and let the user follow what resonates. Don't funnel them through a single path of questions.
+- **Visual** - Use ASCII diagrams liberally when they'd help clarify thinking
+- **Adaptive** - Follow interesting threads, pivot when new information emerges
+- **Patient** - Don't rush to conclusions, let the shape of the problem emerge
+- **Grounded** - Explore the actual codebase when relevant, don't just theorize
+
+---
+
+## What You Might Do
+
+Depending on what the user brings, you might:
+
+**Explore the problem space**
+- Ask clarifying questions that emerge from what they said
+- Challenge assumptions
+- Reframe the problem
+- Find analogies
+
+**Investigate the codebase**
+- Map existing architecture relevant to the discussion
+- Find integration points
+- Identify patterns already in use
+- Surface hidden complexity
+
+**Compare options**
+- Brainstorm multiple approaches
+- Build comparison tables
+- Sketch tradeoffs
+- Recommend a path (if asked)
+
+**Visualize**

+
+## OpenSpec Awareness
+
+You have full context of the OpenSpec system. Use it naturally, don't force it.
+
+### Check for context
+
+At the start, quickly check what exists:
+```bash
+openspec list --json
+```
+
+This tells you:
+- If there are active changes
+- Their names, schemas, and status
+- What the user might be working on
+
+### When no change exists
+
+Think freely. When insights crystallize, you might offer:
+
+- "This feels solid enough to start a change. Want me to create a proposal?"
+- Or keep exploring - no pressure to formalize
+
+### When a change exists
+
+If the user mentions a change or you detect one is relevant:
+
+1. **Read existing artifacts for context**
+   - `openspec/changes/<name>/proposal.md`
+   - `openspec/changes/<name>/design.md`
+   - `openspec/changes/<name>/tasks.md`
+   - etc.
+
+2. **Reference them naturally in conversation**
+   - "Your design mentions using Redis, but we just realized SQLite fits better..."
+   - "The proposal scopes this to premium users, but we're now thinking everyone..."
+
+3. **Offer to capture when decisions are made**
+
+   | Insight Type | Where to Capture |
+   |--------------|------------------|
+   | New requirement discovered | `specs/<capability>/spec.md` |
+   | Requirement changed | `specs/<capability>/spec.md` |
+   | Design decision made | `design.md` |
+   | Scope changed | `proposal.md` |
+   | New work identified | `tasks.md` |
+   | Assumption invalidated | Relevant artifact |
+
+   Example offers:
+   - "That's a design decision. Capture it in design.md?"
+   - "This is a new requirement. Add it to specs?"
+   - "This changes scope. Update the proposal?"
+
+4. **The user decides** - Offer and move on. Don't pressure. Don't auto-capture.
+
+---
+
+## What You Don't Have To Do
+
+- Follow a script
+- Ask the same questions every time
+- Produce a specific artifact
+- Reach a conclusion
+- Stay on topic if a tangent is valuable
+- Be brief (this is thinking time)
+
+---
+

+
+---
+
+## Ending Discovery
+
+There's no required ending. Discovery might:
+
+- **Flow into a proposal**: "Ready to start? I can create a change proposal."
+- **Result in artifact updates**: "Updated design.md with these decisions"
+- **Just provide clarity**: User has what they need, moves on
+- **Continue later**: "We can pick this up anytime"
+
+When it feels like things are crystallizing, you might summarize:
+
+```
+## What We Figured Out
+
+**The problem**: [crystallized understanding]
+
+**The approach**: [if one emerged]
+
+**Open questions**: [if any remain]
+
+**Next steps** (if ready):
+- Create a change proposal
+- Keep exploring: just keep talking
+```
+
+But this summary is optional. Sometimes the thinking IS the value.
+
+---
+
+## Guardrails
+
+- **Don't implement** - Never write code or implement features. Creating OpenSpec artifacts is fine, writing application code is not.
+- **Don't fake understanding** - If something is unclear, dig deeper
+- **Don't rush** - Discovery is thinking time, not task time
+- **Don't force structure** - Let patterns emerge naturally
+- **Don't auto-capture** - Offer to save insights, don't just do it
+- **Do visualize** - A good diagram is worth many paragraphs
+- **Do explore the codebase** - Ground discussions in reality
+- **Do question assumptions** - Including the user's and your own

+When ready to implement, run /opsx:apply
+
+---
+
+**Input**: The user's request should include a change name (kebab-case) OR a description of what they want to build.
+
+**Steps**
+
+1. **If no clear input provided, ask what they want to build**
+
+   Use the **AskUserQuestion tool** (open-ended, no preset options) to ask:
+   > "What change do you want to work on? Describe what you want to build or fix."
+
+   From their description, derive a kebab-case name (e.g., "add user authentication" → `add-user-auth`).
+
+   **IMPORTANT**: Do NOT proceed without understanding what the user wants to build.
+
+2. **Create the change directory**
+   ```bash
+   openspec new change "<name>"
+   ```
+   This creates a scaffolded change at `openspec/changes/<name>/` with `.openspec.yaml`.
+
+3. **Get the artifact build order**
+   ```bash
+   openspec status --change "<name>" --json
+   ```
+   Parse the JSON to get:
+   - `applyRequires`: array of artifact IDs needed before implementation (e.g., `["tasks"]`)
+   - `artifacts`: list of all artifacts with their status and dependencies
+
+4. **Create artifacts in sequence until apply-ready**
+
+   Use the **TodoWrite tool** to track progress through the artifacts.
+
+   Loop through artifacts in dependency order (artifacts with no pending dependencies first):
+
+   a. **For each artifact that is `ready` (dependencies satisfied)**:
+      - Get instructions:
+        ```bash
+        openspec instructions <artifact-id> --change "<name>" --json
+        ```
+      - The instructions JSON includes:
+        - `context`: Project background (constraints for you - do NOT include in output)
+        - `rules`: Artifact-specific rules (constraints for you - do NOT include in output)
+        - `template`: The structure to use for your output file
+        - `instruction`: Schema-specific guidance for this artifact type
+        - `outputPath`: Where to write the artifact
+        - `dependencies`: Completed artifacts to read for context
+      - Read any completed dependency files for context
+      - Create the artifact file using `template` as the structure
+      - Apply `context` and `rules` as constraints - but do NOT copy them into the file
+      - Show brief progress: "Created <artifact-id>"
+
+   b. **Continue until all `applyRequires` artifacts are complete**
+      - After creating each artifact, re-run `openspec status --change "<name>" --json`
+      - Check if every artifact ID in `applyRequires` has `status: "done"` in the artifacts array
+      - Stop when all `applyRequires` artifacts are done
+
+   c. **If an artifact requires user input** (unclear context):
+      - Use **AskUserQuestion tool** to clarify
+      - Then continue with creation
+
+5. **Show final status**
+   ```bash
+   openspec status --change "<name>"
+   ```
+
+**Output**
+
+After completing all artifacts, summarize:
+- Change name and location
+- List of artifacts created with brief descriptions
+- What's ready: "All artifacts created! Ready for implementation."
+- Prompt: "Run `/opsx:apply` or ask me to implement to start working on the tasks."
+
+**Artifact Creation Guidelines**
+
+- Follow the `instruction` field from `openspec instructions` for each artifact type
+- The schema defines what each artifact should contain - follow it
+- Read dependency artifacts for context before creating new ones
+- Use `template` as the structure for your output file - fill in its sections
+- **IMPORTANT**: `context` and `rules` are constraints for YOU, not content for the file
+  - Do NOT copy `<context>`, `<rules>`, `<project_context>` blocks into the artifact
+  - These guide what you write, but should never appear in the output
+
+**Guardrails**
+- Create ALL artifacts needed for implementation (as defined by schema's `apply.requires`)
+- Always read dependency artifacts before creating a new one
+- If context is critically unclear, ask the user - but prefer making reasonable decisions to keep momentum
+- If a change with that name already exists, ask if user wants to continue it or create a new one
+- Verify each artifact file exists after writing before proceeding to next

 ## Analysis
 
-- **get_it** is the absolute leader in all scenarios, especially under deep/nested chains and async.
+- **get_it** remains the clear leader for both speed and memory usage (lowest latency across most scenarios; excellent memory efficiency even on deep chains).
-- **cherrypick** is highly competitive and much faster than riverpod on any complex graph.
+- **kiwi** shows the lowest memory footprint in chainSingleton, but is unavailable for async chains.
-- **riverpod** is only suitable for small/simple DI graphs due to major slowdowns with depth, async, or override.
+- **yx_scope** demonstrates highly stable performance for both sync and async chains, often at the cost of higher memory usage, especially in the register/override scenarios.
+- **cherrypick** comfortably beats riverpod, but is outperformed by get_it/kiwi/yx_scope, especially on async and heavy nested chains. It uses a bit less memory than yx_scope and kiwi, but can spike in memory/latency for override.
+- **riverpod** is unsuitable for deep or async chains—latency and memory usage grow rapidly.
+- **Peak memory (RSS):** usually around 320–340 MB for all DI; riverpod/kiwi occasionally drops below 300MB. named/factory scenarios use much less.
+- **Stability:** yx_scope and get_it have the lowest latency spikes; cherrypick can show peaks on override/async; riverpod is least stable on async (stddev/mean much worse).
 
 ### Recommendations
-- Use **get_it** for performance-critical and deeply nested graphs.
+
-- Use **cherrypick** for scalable/testable apps if a small speed loss is acceptable.
+- **get_it** (and often **kiwi**, if you don't need async): best for ultra-fast deep graphs and minimum peak memory.
-- Use **riverpod** only if you rely on Flutter integration and your DI chains are simple.
+- **yx_scope**: best blend of performance and async stability; perfect for production mixed DI.
+- **cherrypick**: great for modular/testable architectures, unless absolute peak is needed; lower memory than yx_scope in some scenarios.
+- **riverpod**: only for shallow DI or UI wiring in Flutter.

 ## Краткий анализ и рекомендации
 
-- **get_it** всегда лидер, особенно на глубине/асинхронных графах.
+- **get_it** — абсолютный лидер по скорости и памяти на всех графах (минимальная задержка, небольшой peak RSS в любых цепочках).
-- **cherrypick** заметно быстрее riverpod на сложных сценариях, опережая его в разы.
+- **kiwi** — минимальное потребление памяти в chainSingleton/Factory, но не для асинхронности.
-- **riverpod** подходит только для простых/небольших графов — при росте глубины или async/override резко проигрывает по скорости.
+- **yx_scope** — очень ровная производительность даже на сложных async/sync-цепях, иногда с пиком в памяти на override/register, но задержки всегда минимальны.
+- **cherrypick** — стабильнее riverpod, но ощутимо уступает top-3 по латентности на длинных/async-графах; по памяти лучше yx_scope для override/named.
+- **riverpod** — непригоден для глубоких/async-графов: память и время растут очень сильно.
+- **Пиковое потребление памяти**: большинство DI держится в районе 320–340 Мб (большие цепи), на мелких named/factory — крайне мало.
+- **Стабильность**: yx_scope и get_it показывают наименьшие скачки времени; у cherrypick иногда всплески на override/async, у riverpod — на async графе stddev почти равен mean!
 
 ### Рекомендации
-- Используйте **get_it** для критичных к скорости приложений/сложных графов зависимостей.
+- Используйте **get_it** (или **kiwi**, если не нужен async) для максимальной производительности и минимального пикового использования памяти.
-- Выбирайте **cherrypick** для масштабируемых, тестируемых архитектур, если микросекундная разница не критична.
+- **yx_scope** — идеально для production-графов с миксом sync/async.
-- **riverpod** уместен только для реактивного UI или простых графов DI.
+- **cherrypick** — хорошо для модульных и тестируемых приложений, если не требуется абсолютная “микросекундная” производительность.
+- **riverpod** — только если граф плоский или нужно DI только для UI во Flutter.

+> ⚠️ **Important note about using `toInstance` in Module `builder`:**
+>
+> If you register a chain of dependencies via `toInstance` inside a Module's `builder`, **do not** call `scope.resolve<T>()` for types that are also being registered in the same builder — at the moment they are registered.
+>
+> CherryPick initializes all bindings in the builder sequentially. Dependencies registered earlier are not yet available to `resolve` within the same builder execution. Trying to resolve just-registered types will result in an error (`Can't resolve dependency ...`).
+>
+> **How to do it right:**  
+> Manually construct the full dependency chain before calling `toInstance`:
+>
+> ```dart
+> void builder(Scope scope) {
+>   final a = A();
+>   final b = B(a);
+>   final c = C(b);
+>   bind<A>().toInstance(a);
+>   bind<B>().toInstance(b);
+>   bind<C>().toInstance(c);
+> }
+> ```
+>
+> **Wrong:**
+> ```dart
+> void builder(Scope scope) {
+>   bind<A>().toInstance(A());
+>   // Error! At this point, A is not registered yet.
+>   bind<B>().toInstance(B(scope.resolve<A>()));
+> }
+> ```
+>
+> **Wrong:**
+> ```dart
+> void builder(Scope scope) {
+>   bind<A>().toProvide(() => A());
+>   // Error! At this point, A is not registered yet.
+>   bind<B>().toInstance(B(scope.resolve<A>()));
+> }
+> ```
+>
+> **Note:** This limitation applies **only** to `toInstance`. With `toProvide`/`toProvideAsync` and similar providers, you can safely use `scope.resolve<T>()` inside the builder.
+
+
+  > ⚠️ **Special note regarding `.singleton()` with `toProvideWithParams()` / `toProvideAsyncWithParams()`:**
+  >
+  > If you declare a binding using `.toProvideWithParams(...)` (or its async variant) and then chain `.singleton()`, only the **very first** `resolve<T>(params: ...)` will use its parameters; every subsequent call (regardless of params) will return the same (cached) instance.
+  >
+  > **Example:**
+  > ```dart
+  > bind<Service>().toProvideWithParams((params) => Service(params)).singleton();
+  > final a = scope.resolve<Service>(params: 1); // creates Service(1)
+  > final b = scope.resolve<Service>(params: 2); // returns Service(1)
+  > print(identical(a, b)); // true
+  > ```
+  >
+  > Use this pattern only when you want a “master” singleton. If you expect a new instance per params, **do not** use `.singleton()` on parameterized providers.
+
+
+> ℹ️ **Note about `.singleton()` and `.toInstance()`:**
+>
+> Calling `.singleton()` after `.toInstance()` does **not** change the binding’s behavior: the object passed with `toInstance()` is already a single, constant instance that will be always returned for every resolve.
+>
+> It is not necessary to use `.singleton()` with an existing object—this call has no effect.
+>
+> `.singleton()` is only meaningful with providers (such as `toProvide`/`toProvideAsync`), to ensure only one instance is created by the factory.
+

 # CherryPick Flutter
 
 `cherrypick_flutter` offers a Flutter integration to access and manage dependency injection scopes using the `CherryPickProvider`. This setup facilitates accessing the root scope directly from the widget tree, providing a straightforward mechanism for dependences management within Flutter applications.

 # Cherrypick Generator
 
 **Cherrypick Generator** is a Dart code generation library for automating dependency injection (DI) boilerplate. It processes classes and fields annotated with [cherrypick_annotations](https://pub.dev/packages/cherrypick_annotations) and generates registration code for services, modules, and field injection for classes marked as `@injectable`. It supports advanced DI features such as scopes, named bindings, parameters, and asynchronous dependencies.

+>
+> If you declare a binding using `.toProvideWithParams((params) => ...)` (or its async variant) and then call `.singleton()`, the DI container will create and cache **only one instance** on the first `resolve` call—with the initial parameters. All subsequent calls to `resolve<T>(params: ...)` will return that same (cached) instance, **regardless of the new parameters**.
+>
+> **Example:**
+> ```dart
+> bind<Service>().toProvideWithParams((params) => Service(params)).singleton();
+>
+> final a = scope.resolve<Service>(params: 1); // Creates Service(1)
+> final b = scope.resolve<Service>(params: 2); // Returns Service(1)
+> print(identical(a, b)); // true
+> ```
+>
+> In other words:  
+> - The provider function receives parameters only on its first call,
+> - After that, no matter what parameters are passed, the same instance is always returned.
+>
+> **Recommendation:**  
+> Use `.singleton()` with parameterized providers only if you are sure all parameters should always be identical, or you intentionally want a “master” instance. Otherwise, omit `.singleton()` to ensure a new object is constructed for every unique `params` value.

+> Если вы объявляете биндинг через `.toProvideWithParams((params) => ...)` (или асинхронный вариант) и затем вызываете `.singleton()`, DI-контейнер создаст и закэширует **только один экземпляр** при первом вызове `resolve` — с первыми переданными параметрами. Все последующие вызовы `resolve<T>(params: ...)` вернут этот же (кэшированный) объект **независимо от новых параметров**.
+>
+> **Пример:**
+> ```dart
+> bind<Service>().toProvideWithParams((params) => Service(params)).singleton();
+>
+> final a = scope.resolve<Service>(params: 1); // Создаётся Service(1)
+> final b = scope.resolve<Service>(params: 2); // Возвращается уже Service(1)
+> print(identical(a, b)); // true
+> ```
+>
+> То есть:  
+> - параметры работают только для первого вызова,
+> - дальше всегда возвращается экземпляр, созданный при первом обращении.
+>
+> **Рекомендация:**  
+> Используйте `.singleton()` совместно с провайдерами с параметрами только тогда, когда вы точно уверены, что все параметры всегда должны совпадать, или нужны именно “мастер”-экземпляры. В противном случае не используйте `.singleton()`, чтобы каждый вызов с новыми parameters создавал новый объект.

+# Release - CherryPick 3.x
+
+> **CherryPick** — a lightweight and modular DI framework for Dart and Flutter that solves dependency injection through strong typing, code generation, and dependency control.
+
+Version **3.x** was recently released with significant improvements.
+
+## Main Changes in 3.x
+
+* **O(1) dependency resolution** — thanks to Map indexing of bindings, performance does not depend on the size of the scope in the DI graph. This provides noticeable speedup in large projects.
+* **Protection against circular dependencies** — checking works both within a single scope and across the entire hierarchy. When a cycle is detected, an informative exception with the dependency chain is thrown.
+* **Integration with Talker** — all DI events (registration, creation, deletion, errors) are logged and can be displayed in the console or UI.
+* **Automatic resource cleanup** — objects implementing `Disposable` are properly released when the scope is closed.
+* **Stabilized declarative approach support** — annotations and code generation now work more reliably and are more convenient for use in projects.
+
+## Resource Cleanup Example
+
+```dart
+class MyServiceWithSocket implements Disposable {
+  @override
+  Future<void> dispose() async {
+    await socket.close();
+    print('Socket closed!');
+  }
+}
+
+class AppModule extends Module {
+  @override
+  void builder(Scope currentScope) {
+    // singleton Api
+    bind<MyServiceWithSocket>()
+      .toProvide(() => MyServiceWithSocket())
+      .singleton();
+  }
+}
+
+scope.installModules([AppModule()]);
+
+await CherryPick.closeRootScope(); // will wait for async dispose to complete
+```
+
+## Circular Dependency Checking
+
+One of the new features in CherryPick 3.x is built-in cycle protection.
+This helps catch situations early where services start depending on each other recursively.
+
+### How to Enable Checking
+
+For checking within a single scope:
+
+```dart
+final scope = CherryPick.openRootScope();
+scope.enableCycleDetection();
+```
+
+For global checking across the entire hierarchy:
+
+```dart
+CherryPick.enableGlobalCycleDetection();
+CherryPick.enableGlobalCrossScopeCycleDetection();
+final rootScope = CherryPick.openRootScope();
+```
+
+### How a Cycle Can Occur
+
+Suppose we have two services that depend on each other:
+
+```dart
+class UserService {
+  final OrderService orderService;
+  UserService(this.orderService);
+}
+
+class OrderService {
+  final UserService userService;
+  OrderService(this.userService);
+}
+```
+
+If we register them in the same scope:
+
+```dart
+class AppModule extends Module {
+  @override
+  void builder(Scope currentScope) {
+    bind<UserService>().toProvide(() => UserService(scope.resolve()));
+    bind<OrderService>().toProvide(() => OrderService(scope.resolve()));
+  }
+}
+
+final scope = CherryPick.openRootScope()
+  ..enableCycleDetection()
+  ..installModules([AppModule()]);
+
+scope.resolve<UserService>();
+```
+
+Then when trying to resolve the dependency, an exception will be thrown:
+
+```bash
+❌ Circular dependency detected for UserService
+Dependency chain: UserService -> OrderService -> UserService
+```
+
+This way, the error is detected immediately, not "somewhere in runtime".
+
+## Integration with Talker
+
+CherryPick 3.x allows logging all DI events through [Talker](https://pub.dev/packages/talker): registration, object creation, deletion, and errors. This is convenient for debugging and diagnosing the dependency graph.
+
+Connection example:
+
+```dart
+final talker = Talker();
+final observer = TalkerCherryPickObserver(talker);
+CherryPick.setGlobalObserver(observer);
+```
+
+After this, DI events will be displayed in the console or UI:
+
+```bash
+┌───────────────────────────────────────────────────────────────
+│ [info]    9:41:33  | [scope opened][CherryPick] scope_1757054493089_7072
+└───────────────────────────────────────────────────────────────
+┌───────────────────────────────────────────────────────────────
+│ [verbose] 9:41:33  | [diagnostic][CherryPick] Scope created: scope_1757054493089_7072 {type: Scope, name: scope_1757054493089_7072, description: scope created}
+└───────────────────────────────────────────────────────────────
+```
+
+In the log, you can see when scopes are created, which objects are registered and deleted, and catch errors and cycles in real time.
+
+
+## Declarative Approach with Annotations
+
+In addition to fully programmatic module descriptions, CherryPick supports **declarative DI style through annotations**.  
+This allows minimizing manual code and automatically generating modules and mixins for automatic dependency injection.
+
+Example of a declarative module:
+
+```dart
+@module()
+abstract class AppModule extends Module {
+  @provide()
+  @singleton()
+  Api api() => Api();
+
+  @provide()
+  Repo repo(Api api) => Repo(api);
+}
+````
+
+After code generation, you can automatically inject dependencies into widgets or services:
+
+```dart
+@injectable()
+class MyScreen extends StatelessWidget with _$MyScreen {
+  @inject()
+  late final Repo repo;
+
+  MyScreen() {
+    _inject(this);
+  }
+}
+```
+
+This way you can choose an approach in development: **programmatic (imperative) with explicit dependency registration** or **declarative through annotations**.
+
+
+## Who Might Find CherryPick Useful?
+
+* Projects where it's important to guarantee **no cycles in the dependency graph**;
+* Teams that want to **minimize manual DI code** and use a declarative style with annotations;
+* Applications that require **automatic resource cleanup** (sockets, controllers, streams).

+# Release - CherryPick 3.x
+
+> **CherryPick** — лёгкий и модульный DI-фреймворк для Dart и Flutter, который решает задачу через строгую типизацию, кодогенерацию и контроль за зависимостями.
+
+Недавно вышла версия **3.x**, где появились заметные улучшения.
+
+
+## Основные изменения в 3.x
+
+* **O(1) разрешение зависимостей** — благодаря Map-индексации биндингов производительность не зависит от размера скоупа в DI графе. На больших проектах это даёт ощутимое ускорение.
+* **Защита от циклических зависимостей** — проверка работает как внутри одного scope, так и во всей иерархии. При обнаружении цикла выбрасывается информативное исключение с цепочкой зависимостей.
+* **Интеграция с Talker** — все события DI (регистрация, создание, удаление, ошибки) логируются и могут выводиться в консоль или UI.
+* **Автоматическая очистка ресурсов** — объекты, реализующие `Disposable`, корректно освобождаются при закрытии scope.
+* **Стабилизирована поддержка декларативного подхода** — аннотации и генерация кода теперь работают надёжнее и удобнее для использования в проектах.
+
+
+## Пример с очисткой ресурсов
+
+```dart
+class MyServiceWithSocket implements Disposable {
+  @override
+  Future<void> dispose() async {
+    await socket.close();
+    print('Socket закрыт!');
+  }
+}
+
+class AppModule extends Module {
+  @override
+  void builder(Scope currentScope) {
+    // singleton Api
+    bind<MyServiceWithSocket>()
+      .toProvide(() => MyServiceWithSocket())
+      .singleton();
+  }
+}
+
+scope.installModules([AppModule()]);
+
+await CherryPick.closeRootScope(); // дождётся завершения async dispose
+```
+
+## Проверка циклических зависимостей
+
+Одна из новинок CherryPick 3.x — встроенная защита от циклов.
+Это помогает на раннем этапе отлавливать ситуации, когда сервисы начинают зависеть друг от друга рекурсивно.
+
+### Как включить проверку
+
+Для проверки внутри одного scope:
+
+```dart
+final scope = CherryPick.openRootScope();
+scope.enableCycleDetection();
+```
+
+Для глобальной проверки во всей иерархии:
+
+```dart
+CherryPick.enableGlobalCycleDetection();
+CherryPick.enableGlobalCrossScopeCycleDetection();
+final rootScope = CherryPick.openRootScope();
+```
+
+### Как может возникнуть цикл
+
+Предположим, у нас есть два сервиса, которые зависят друг от друга:
+
+```dart
+class UserService {
+  final OrderService orderService;
+  UserService(this.orderService);
+}
+
+class OrderService {
+  final UserService userService;
+  OrderService(this.userService);
+}
+```
+
+Если зарегистрировать их в одном scope:
+
+```dart
+class AppModule extends Module {
+  @override
+  void builder(Scope currentScope) {
+    bind<UserService>().toProvide(() => UserService(scope.resolve());
+    bind<OrderService>().toProvide(() => OrderService(scope.resolve()));
+  }
+}
+
+final scope = CherryPick.openRootScope()
+  ..enableCycleDetection()
+  ..installModules([AppModule()]);
+
+scope.resolve<UserService>();
+```
+
+То при попытке разрешить зависимость будет выброшено исключение:
+
+```bash
+❌ Circular dependency detected for UserService
+Dependency chain: UserService -> OrderService -> UserService
+```
+
+Таким образом, ошибка выявляется сразу, а не «где-то в runtime».
+
+## Интеграция с Talker
+
+CherryPick 3.x позволяет логировать все события DI через [Talker](https://pub.dev/packages/talker): регистрацию, создание объектов, удаление и ошибки. Это удобно для отладки и диагностики графа зависимостей.
+
+Пример подключения:
+
+```dart
+final talker = Talker();
+final observer = TalkerCherryPickObserver(talker);
+CherryPick.setGlobalObserver(observer);
+```
+
+После этого в консоли или UI будут отображаться события DI:
+
+```bash
+┌───────────────────────────────────────────────────────────────
+│ [info]    9:41:33  | [scope opened][CherryPick] scope_1757054493089_7072
+└───────────────────────────────────────────────────────────────
+┌───────────────────────────────────────────────────────────────
+│ [verbose] 9:41:33  | [diagnostic][CherryPick] Scope created: scope_1757054493089_7072 {type: Scope, name: scope_1757054493089_7072, description: scope created}
+└───────────────────────────────────────────────────────────────
+```
+
+В логе можно увидеть, когда scope создаётся, какие объекты регистрируются и удаляются, а также отлавливать ошибки и циклы в реальном времени.
+
+
+## Декларативный подход с аннотациями
+
+Помимо полностью программного описания модулей, CherryPick поддерживает **декларативный стиль DI через аннотации**.  
+Это позволяет минимизировать ручной код и автоматически генерировать модули и mixin для автоподстановки зависимостей.
+
+Пример декларативного модуля:
+
+```dart
+@module()
+abstract class AppModule extends Module {
+  @provide()
+  @singleton()
+  Api api() => Api();
+
+  @provide()
+  Repo repo(Api api) => Repo(api);
+}
+````
+
+После генерации кода можно автоматически подтягивать зависимости в виджеты или сервисы:
+
+```dart
+@injectable()
+class MyScreen extends StatelessWidget with _$MyScreen {
+  @inject()
+  late final Repo repo;
+
+  MyScreen() {
+    _inject(this);
+  }
+}
+```
+
+Таким образом можно выбрать подход в разработке: **программный (императивный) с явной регистрацией зависимостей** или **декларативный через аннотации**.
+
+
+## Кому может быть полезен CherryPick?
+
+* проектам, где важно гарантировать **отсутствие циклов в графе зависимостей**;
+* командам, которые хотят **минимизировать ручной DI-код** и использовать декларативный стиль с аннотациями;
+* приложениям, где требуется **автоматическое освобождение ресурсов** (сокеты, контроллеры, потоки).

+
+## Что такое CherryPick?
+
+- Лёгкий и модульный framework для внедрения зависимостей (DI)
+- Фокус: производительность, безопасность и лаконичный код
+- Применяется во frontend, backend, CLI
+
+---
+
+## Эволюция: что нового в 3.x?
+
+- Оптимизация скорости разрешения зависимостей
+- Интеграция с Talker для наглядного логирования DI-событий
+- Защита от циклических зависимостей на уровне ядра
+- Полностью декларативное описание DI через аннотации и генерацию кода
+- Автоматическая очистка ресурсов
+
+---
+
+## Быстро
+
+* Мгновенное разрешение зависимостей
+
+---
+
+### Мгновенное разрешение зависимостей
+
+- Операция resolve<T> теперь выполняется за O(1)
+- Используется Map-индексация всех биндингов в каждом скоупе (в среднем ускорение в 10x+ на крупных графах)
+- Производительность не зависит от размера приложения
+
+---
+
+## Безопасно
+
+* Циклические зависимости больше не страшны
+* Интеграция с Talker и расширенное логирование
+
+---
+
+### Циклические зависимости больше не страшны
+
+- CherryPick 3.x автоматически выявляет циклы при разрешении зависимостей.
+- Возможна проверка как внутри отдельного scope, так и во всём DI-графе (глобально).
+
+---
+
+#### Как включить проверку циклов
+
+
+- Для защиты только внутри одного scope:
+
+```dart
+// 1. Для текущего scope (локальная проверка)
+final scope = CherryPick.openRootScope();
+scope.enableCycleDetection();
+```
+
+- Для защиты всей иерархии скоупов:
+
+```dart
+// 2. Для всей иерархии скоупов (глобальная проверка)
+CherryPick.enableGlobalCycleDetection();
+CherryPick.enableGlobalCrossScopeCycleDetection();
+final rootScope = CherryPick.openRootScope();
+```
+
+---
+
+#### Пример обработки ошибки
+
+При обнаружении цикла будет выброшено исключение с подробной трассировкой:
+
+```dart
+try {
+  scope.resolve<A>();
+} on CircularDependencyException catch(e) {
+  print(e.dependencyChain);
+}
+```
+
+```bash
+=== Circular Dependency Detection Example ===
+
+1. Attempt to create a scope with circular dependencies:
+❌ Circular dependency detected: CircularDependencyException: Circular dependency detected for UserService
+Dependency chain: UserService -> OrderService -> UserService
+```
+
+---
+
+### Интеграция с Talker и расширенное логирование
+
+- Всё, что происходит в DI: регистрация, создание, удаление, ошибки ― теперь логируется!
+- Достаточно подключить observer:
+
+```dart
+  final talker = Talker();
+  final talkerLogger = TalkerCherryPickObserver(talker);
+  CherryPick.setGlobalObserver(talkerLogger);
+```
+- Логи сразу видны в консоли, UI 
+
+```bash
+┌──────────────────────────────────────────────────────────────────────────────────────────────────────────────
+│ [info] | 9:41:33 89ms | [scope opened][CherryPick] scope_1757054493089_7072

+
+## Просто
+
+* Декларативный DI
+* Автоматическая очистка ресурсов
+
+---
+
+### Декларативный DI: аннотации и генерация кода
+
+- Описывайте зависимости с помощью аннотаций
+- Автоматически генерируется модуль DI и mixin для автоподстановки зависимостей
+
+```dart
+@module()
+abstract class AppModule extends Module {
+  @provide()
+  @singleton()
+  Api api() => Api();
+  @provide()
+  Repo repo(Api api) => Repo(api);
+}
+```
+
+Регистрация модуля
+
+```dart
+final scope = openRootScope()
+  ..installModules([$AppModule()]);
+```
+
+---
+
+### Field injection: минимум кода — максимум удобства
+
+```dart
+@injectable()
+class MyScreen  extends StatelessWidget with _$MyScreen {
+  @inject()
+  late final Repo repo;
+
+  MyScreen() {
+    _inject(this);
+  }
+}
+```
+
+- После генерации mixin и вызова `screen._inject()` — зависимости готовы
+- Сильная типизация, никаких ручных вызовов resolve
+
+---
+
+## Автоматическая очистка ресурсов
+
+Автоматическая очистка ресурсов (контроллеры, потоки, сокеты, файлы и др.).
+
+Если вы регистрируете объект, реализующий Disposable, через DI-контейнер, CherryPick вызовет его метод dispose() при закрытии скоупа.
+
+```dart
+class MyServiceWithSocket implements Disposable {
+  @override
+  Future<void> dispose() async {
+    await socket.close();
+    print('Socket закрыт!');
+  }
+}
+
+scope.installModules([
+  Module((bind) => bind<MyServiceWithSocket>().toProvide(() => MyServiceWithSocket()).singleton()),
+]);
+
+await CherryPick.closeRootScope(); // дождётся завершения async очистки
+```
+
+---
+
+## Почему это удобно?  
+### Сравнение с ручным DI
+
+|| Аннотации  | Ручной DI   |
+|:---|:-----------|:------------|
+|Гибко|✅|✅|
+|Кратко|✅|❌|
+|Безопасно|✅|❌ (легко ошибиться)|
