Integrate Skill

Wire mnemonic memory operations into other Claude Code plugins.

When to Use

Use this skill when you want to:

• Add memory to an existing plugin - Make any plugin mnemonic-aware
• Enable cross-session learning - Let plugins recall past decisions and learnings
• Automate capture triggers - Set up hooks that suggest memory capture at the right time
• Migrate legacy integrations - Convert old marker-less integrations to the new format

Don't use this skill if:

• You're building a new plugin from scratch (use the core skill directly)
• You only need to search/capture memories (use /mnemonic:search and /mnemonic:capture)

Overview

This skill enables integrating mnemonic memory capture and recall into other Claude Code plugins. Integration happens through two mechanisms:

1. Markdown Workflow Edits - Add explicit workflow steps to command/skill/agent markdown files
2. Event-Driven Hooks - Add hooks that detect events and inject memory context

Both mechanisms work together: Markdown provides explicit workflow guidance, hooks provide automatic event detection.

Quick Start

# Integrate a plugin (adds mnemonic protocol to all components)
/mnemonic:integrate {plugin_path}

# Preview changes without applying
/mnemonic:integrate {plugin_path} --dry-run

# Remove integration
/mnemonic:integrate {plugin_path} --remove

# Rollback last integration (git required)
/mnemonic:integrate {plugin_path} --rollback

For detailed options, see "How to Use This Skill" below.

[CRITICAL] PROTOCOL CONTENT MUST BE VERBATIM

For the mnemonic protocol section (## Memory), you MUST:

1. Read templates/mnemonic-protocol.md - this is the single source of truth
2. Insert its content EXACTLY as-is, including sentinel markers
3. Never abbreviate, modify, or "improve" the protocol text

Exception: Event-driven hooks (Pattern D) are optional and use the provided template code.

Sentinel Markers

All integrations use sentinel markers for clean updates and removal:

<!-- BEGIN MNEMONIC PROTOCOL -->

## Memory

Search first: `/mnemonic:search {relevant_keywords}`
Capture after: `/mnemonic:capture {namespace} "{title}"`

Run `/mnemonic:list --namespaces` to see available namespaces from loaded ontologies.

<!-- END MNEMONIC PROTOCOL -->

Benefits:

• Updates: Replace content between markers without affecting rest of file
• Removal: Delete everything between markers cleanly
• Detection: Identify already-integrated files
• Migration: Convert old integrations to marker-wrapped format

Template Source: templates/mnemonic-protocol.md is the single source of truth.

Integration Workflow

For most users: Skip to "How to Use This Skill" below for command-line usage. This section details the internal steps the skill performs.

Phase 1: Analyze Target Plugin

# Read plugin manifest
cat {plugin_path}/.claude-plugin/plugin.json

# List all components
ls -la {plugin_path}/commands/ {plugin_path}/skills/ {plugin_path}/agents/ 2>/dev/null

For each component, determine:

• Does it CREATE something? → Candidate for capture after
• Does it MAKE DECISIONS? → Candidate for capture after
• Does it RESEARCH something? → Candidate for recall before

Phase 2: Identify Integration Points

Phase 3: Read Template (MANDATORY)

Use the template verbatim - do not modify the protocol content.

# Read the template - this is the ONLY content to insert
cat "${CLAUDE_PLUGIN_ROOT}/templates/mnemonic-protocol.md"

The template already contains:

• <!-- BEGIN MNEMONIC PROTOCOL --> start marker
• <!-- END MNEMONIC PROTOCOL --> end marker
• Complete protocol content between markers (see "Sentinel Markers" section above)

Phase 4: Insert Template With Markers

For each target file:

1. Check for existing markers:

   grep -l "BEGIN MNEMONIC PROTOCOL" {file}
   

2. If markers exist: Replace content BETWEEN markers with template content

3. If no markers: Insert the COMPLETE template (including markers) after frontmatter

NEVER insert content without the sentinel markers.

Phase 5: Update Tool Access

Mnemonic operations require certain tools. Add them to target component's allowed-tools:

Required tools for mnemonic integration:

• Bash - For git operations and memory file creation
• Glob - For finding memory files
• Grep - For searching memory content
• Read - For reading memory files
• Write - For creating memory files

How to update:

For agents/skills with frontmatter:

---
name: some-agent
allowed-tools:
  - Bash    # Add if missing
  - Glob    # Add if missing
  - Grep    # Add if missing
  - Read    # Add if missing
  - Write   # Add if missing
  # ... existing tools
---

Check existing allowed-tools and add only what's missing.

Integration Patterns

MANDATORY RULES (Non-negotiable):

1. Use template verbatim - Read templates/mnemonic-protocol.md and insert exactly as-is
2. Keep sentinel markers - Template content must stay within <!-- BEGIN/END MNEMONIC PROTOCOL --> markers
3. Insert at TOP - Immediately after frontmatter, before any other content
4. Don't modify protocol - The protocol text is standardized; only hooks (Pattern D) may be customized

Standard Protocol (From Template)

Read and insert template content with markers:

# Read template content
PROTOCOL=$(cat "${CLAUDE_PLUGIN_ROOT}/templates/mnemonic-protocol.md")

# Insert after frontmatter with markers

See template content in "Sentinel Markers" section above.

Namespaces: Run /mnemonic:list --namespaces to see available namespaces from loaded ontologies. Base namespaces include _semantic/*, _episodic/*, and _procedural/* from mif-base ontology.

Graceful Fallthrough

The template uses /mnemonic:search and /mnemonic:capture skills which:

• Fail gracefully if mnemonic plugin is uninstalled (skills simply won't be available)
• No errors or crashes in integrated plugins
• Seamless degradation - agent continues without memory operations

Pattern D: Event-Driven Hooks (Optional)

Applies to: Plugins that need automatic capture signals

Note: Hooks provide signals only. The markdown patterns above are primary.

Create hooks/mnemonic-signal.py:

#!/usr/bin/env python3
import json, os

def main():
    tool_input = json.loads(os.environ.get("CLAUDE_TOOL_INPUT", "{}"))
    file_path = tool_input.get("file_path", "")

    # Detect capture-worthy files
    namespace = None
    if "/adr/" in file_path: namespace = "_semantic/decisions"
    elif "/docs/" in file_path: namespace = "_semantic/knowledge"

    if namespace:
        print(json.dumps({
            "continue": True,
            "hookSpecificOutput": {
                "hookEventName": "PostToolUse",
                "additionalContext": f"**CAPTURE:** `/mnemonic:capture {namespace}`"
            }
        }))
    else:
        print(json.dumps({"continue": True}))

if __name__ == "__main__":
    main()

Target Plugin Examples

All integrations use the standard template from templates/mnemonic-protocol.md with sentinel markers.

ADR Plugin

Files to modify: commands/adr-new.md, agents/adr-author.md

Insert template after frontmatter. Replace {relevant_keywords} with {decision_topic} if needed.

Documentation Review Plugin

Files to modify: commands/doc-create.md, commands/doc-review.md

Insert template after frontmatter. Use generic keywords.

Feature Dev Plugin

Files to modify: agents/*.md, skills/*.md

Insert template after frontmatter. Replace {relevant_keywords} with {feature} if needed.

How to Use This Skill

Insert/Update Mode (Default)

/mnemonic:integrate {plugin_path}

Inserts or updates mnemonic protocol with sentinel markers. If markers already exist, updates content between them.

Remove Mode

/mnemonic:integrate {plugin_path} --remove

Cleanly removes mnemonic protocol by deleting everything between sentinel markers.

Migrate Mode

/mnemonic:integrate {plugin_path} --migrate

Finds old marker-less integrations and replaces them with marker-wrapped version from template.

Detection patterns for migration:

• ## Memory Operations or ## Memory section without markers
• Content containing rg -i, /mnemonic:capture, ${MNEMONIC_ROOT}/

Analyze Only Mode

/mnemonic:integrate {plugin_path} --analyze

Outputs proposed modifications without making changes.

Dry Run Mode

/mnemonic:integrate {plugin_path} --dry-run

Shows exactly what changes would be made without applying them. Useful for reviewing integration before committing.

Dry run output includes:

• Files that would be created
• Files that would be modified (with diff preview)
• Tools that would be added to allowed-tools
• Git commit that would be created

Example output:

DRY RUN - No changes will be made

Plugin: ~/.claude/plugins/cache/zircote/adr/0.2.0/
Git repo: ✓ Found

Changes that would be made:

1. MODIFY: commands/adr-new.md
   + ## Post-Creation: Capture to Mnemonic
   + After creating the file, capture the key details...
   (15 lines added)

2. MODIFY: agents/adr-author.md
   + ## Before Starting: Check Related Memories
   + Use mnemonic recall workflow...
   (12 lines added)

   TOOLS: Would add [Bash, Glob, Grep, Read, Write] to allowed-tools

3. CREATE: hooks/mnemonic-suggest.py
   (45 lines, template from mnemonic/templates/plugin-hooks/)

4. CREATE/MERGE: hooks/hooks.json
   + PostToolUse matcher for Write tool

Git commit that would be created:
  feat(mnemonic): integrate memory capture and recall

To apply these changes, run without --dry-run flag.

Full Integration Mode

/mnemonic:integrate {plugin_path}

Analyzes plugin and applies all integration modifications.

Specific Component

/mnemonic:integrate {plugin_path}/commands/adr-new.md

Integrates mnemonic into a specific command/skill file.

Rollback Mode

/mnemonic:integrate {plugin_path} --rollback

Reverts the last mnemonic integration commit. Only works if plugin has git.

Rollback workflow:

1. Find integration commit - Search for commits with "feat(mnemonic)" message
2. Show what will be reverted - Display the commit diff
3. Confirm with user - Ask before reverting
4. Revert commit - Use git revert to cleanly undo changes
5. Report - Show reverted files and new commit hash

Example:

/mnemonic:integrate ~/.claude/plugins/cache/zircote/adr/ --rollback

Output:

Found mnemonic integration commit:
  abc1234 feat(mnemonic): integrate memory capture and recall
  Date: 2026-01-24 15:30
  Files: 4 changed

This will revert:
  - commands/adr-new.md (remove capture section)
  - agents/adr-author.md (remove recall section)
  - hooks/mnemonic-suggest.py (delete file)
  - hooks/hooks.json (remove PostToolUse entry)

Proceed with rollback? [y/N]

Rollback implementation:

cd {plugin_path}

# Find the mnemonic integration commit
COMMIT=$(git log --oneline --grep="feat(mnemonic)" -1 | cut -d' ' -f1)

if [ -z "$COMMIT" ]; then
  echo "No mnemonic integration commit found"
  exit 1
fi

# Show what will be reverted
echo "Will revert commit: $COMMIT"
git show --stat $COMMIT

# Revert the commit (creates a new revert commit)
git revert --no-edit $COMMIT

echo "✓ Rollback complete"
git log -1 --oneline

Note: Rollback creates a new revert commit, preserving history. To completely remove the integration commit, use git reset --hard HEAD~1 instead (destructive).

Safety Considerations:

• ⚠️ Rollback only works if plugin has git (non-git plugins warn at integration time)
• ⚠️ If you've made manual changes since integration, rollback will revert those too
• ⚠️ Failed rollbacks leave partial state - check git status and resolve manually
• ✅ Rollback is non-destructive by default (creates revert commit)
• ✅ Original integration is preserved in git history for reference

Workflow Steps

Note: This section describes internal mechanics. For usage instructions, see "How to Use This Skill" above.

When invoked, this skill:

Standard Mode (Insert/Update):

1. Read template - Load templates/mnemonic-protocol.md as source of truth
2. Read plugin manifest - Parse .claude-plugin/plugin.json
3. List components - Find all commands, skills, agents, hooks
4. For each component:
   • Check for existing sentinel markers
   • If markers exist: Update content between them
   • If no markers: Insert after frontmatter with markers
5. Update tool access - Add required tools (Bash, Glob, Grep, Read, Write)
6. Commit changes - Create atomic git commit for rollback
7. Report results - Summarize what was integrated and commit hash

Remove Mode (--remove):

1. List components - Find all commands, skills, agents, hooks
2. For each component:
   • Find sentinel markers (<!-- BEGIN/END MNEMONIC PROTOCOL -->)
   • Delete everything between markers (inclusive)
3. Commit changes - Create git commit for the removal
4. Report results - Summarize what was removed

Migrate Mode (--migrate):

1. List components - Find all commands, skills, agents, hooks
2. For each component:
   • Detect old patterns: ## Memory Operations or ## Memory without markers
   • Detect content indicators: rg -i, /mnemonic:capture, ${MNEMONIC_ROOT}/
   • Replace old section with marker-wrapped version from template
3. Commit changes - Create git commit
4. Report results - Summarize migrated files

Dry Run Mode (--dry-run):

1. Perform analysis - Same as standard/remove/migrate mode
2. Display changes - Show what WOULD be modified (with diffs)
3. Exit - No changes applied

Rollback Mode (--rollback):

1. Check git repository - Verify plugin has git
2. Find integration commit - Search for "feat(mnemonic)" commit
3. Display changes - Show what will be reverted
4. Confirm - Ask user to confirm rollback
5. Revert commit - Run git revert on integration commit
6. Report - Show reverted files and new commit hash

Verification

After integration, verify by:

1. Run integrated command - Execute the modified command
2. Check for capture prompt - Verify Claude suggests memory capture
3. Create a memory - Confirm memory is created correctly
4. Test recall - Search for the new memory

# Verify memory was created
/mnemonic:status

# Search for content
/mnemonic:search {topic}

Best Practices

1. Always analyze first - Use --analyze to preview changes
2. Test integration - Run modified commands to verify
3. Keep sections minimal - Integration text should be concise
4. Use consistent patterns - All capture sections should follow same format
5. Don't duplicate - Check if integration already exists
6. Document changes - Note which files were modified

Git Workflow for Plugin Modifications

When integrating mnemonic into a plugin, track changes with git for clean rollback.

Check for Git Repository

cd {plugin_path}

# Check if git repo exists
if [ -d .git ]; then
  echo "✓ Git repository found"
else
  echo "⚠ No git repository - changes will not be committed"
  echo "  Consider: git init"
fi

Atomic Commit Pattern

If git repository exists, create single atomic commit with all integration changes:

cd {plugin_path}

# Stage only the specific modified files (not git add -A for security)
git add SKILL.md README.md hooks/*.py  # Example - list actual modified files

# Create descriptive commit
git commit -m "feat(mnemonic): integrate memory capture and recall" \
           -m "Added mnemonic integration via integrate skill" \
           -m "Enables persistent memory across Claude sessions"

Or for more detailed commit messages, use a heredoc:

git commit -F - << 'EOF'
feat(mnemonic): integrate memory capture and recall

Added mnemonic integration:
- Capture workflow for [list components]
- Recall pattern for [list components]
- Event hooks for [list triggers]

Enables persistent memory across Claude sessions.
Integration by: mnemonic integrate skill
EOF

Non-Git Plugins

If target plugin has no git repository:

1. Warn user but proceed with integration
2. List changes made for manual review
3. Suggest initializing git for future modifications

Example output:

⚠ Warning: Plugin has no git repository
  Integration complete but changes are not tracked.
  Files modified:
    - commands/adr-new.md
    - agents/adr-author.md
    - hooks/mnemonic-suggest.py
  Consider: cd {plugin_path} && git init

Rollback

If integration needs to be undone:

cd {plugin_path}

# View what was changed
git show HEAD

# Undo the integration commit
git revert HEAD

# Or reset completely (discards commit)
git reset --hard HEAD~1

Verification

After commit, verify integration:

# Show commit details
git log -1 --stat

# Show what changed
git diff HEAD~1

Implementation Library

The integrate skill is backed by a Python library located at skills/integrate/lib/.

Library Components

Using the Library

The library can be invoked directly via command line:

# Integrate a plugin
python3 skills/integrate/lib/integrator.py /path/to/plugin --mode integrate

# Verify integration
python3 skills/integrate/lib/integrator.py /path/to/plugin --mode verify

# Remove integration
python3 skills/integrate/lib/integrator.py /path/to/plugin --mode remove

# Dry run (preview changes)
python3 skills/integrate/lib/integrator.py /path/to/plugin --mode integrate --dry-run

# JSON output
python3 skills/integrate/lib/integrator.py /path/to/plugin --json

Individual Tool Usage

# Check for markers
python3 skills/integrate/lib/marker_parser.py /path/to/file.md --check

# Extract content between markers
python3 skills/integrate/lib/marker_parser.py /path/to/file.md --extract

# Validate template
python3 skills/integrate/lib/template_validator.py /path/to/template.md

# List tools in frontmatter
python3 skills/integrate/lib/frontmatter_updater.py /path/to/file.md --list

Integration Manifest

After successful integration, a .mnemonic-integration-manifest.json file is created in the plugin root:

{
  "version": "1.0.0",
  "integrated_at": "2026-01-27T10:30:00Z",
  "template_path": "templates/mnemonic-protocol.md",
  "files": [
    {"path": "commands/example.md", "action": "inserted", "success": true}
  ],
  "tools_required": ["Bash", "Glob", "Grep", "Read", "Write"]
}

Security Features

The library includes several security measures:

• Path validation - All file paths are validated to be within plugin root
• Symlink protection - Symlinks pointing outside plugin root are rejected
• Rollback support - Failed integrations can be automatically rolled back
• Template validation - Templates are checked for executable code patterns
