Tools Migrate

Tools Migrate — Bidirectional Skill & Agent Migration

Migrate skills and agents between this plugin (lw-workflow) and a target project directory. Adapts tools to the target's architecture, infrastructure, and conventions.

Directions

Argument Parsing

Parse $ARGUMENTS to extract:

• Direction: first word — to or from
• Project path: remaining text — absolute or relative path to the target project

If direction or path is missing/ambiguous, ask the user before proceeding.

Resolve the project path to an absolute path. Verify it exists and contains a project (look for package.json, CLAUDE.md, .git, or similar markers). If the path doesn't exist, STOP and tell the user.

Phase 1: Discovery

Perform all discovery in parallel where possible.

1A. Inventory This Plugin

Read the plugin manifest and enumerate all skills and agents:

Skills — For each directory under skills/:

• Read SKILL.md frontmatter (name, description, allowed-tools)
• Note the number of reference files
• Get last modified date: git log -1 --format=%ai -- skills/<name>/

Agents — For each file under agents/:

• Read frontmatter (name, description, model, permissionMode)
• Get last modified date: git log -1 --format=%ai -- agents/<name>.md

1B. Inventory Target Project

Read the target project's structure:

1. CLAUDE.md — Read fully. Extract:

   • Project name, description, tech stack
   • Available MCP servers and integrations (LINEAR INTEGRATION, MCP SERVERS, etc.)
   • Build/test/lint commands (COMMANDS section)
   • Project structure (STRUCTURE, FOLDER STRUCTURE sections)
   • Environments and deployment setup (ENVIRONMENTS section)
   • Any existing skill/agent tables or references

2. Existing skills — Glob for .claude/skills/*/SKILL.md in the target project

   • Read each SKILL.md frontmatter
   • Get last modified date from git if available

3. Existing agents — Glob for .claude/agents/*.md in the target project

   • Read each agent frontmatter
   • Get last modified date from git if available

4. Package/config files — Read package.json, tsconfig.json to understand:

   • Language (TypeScript, JavaScript, Python, etc.)
   • Framework (Next.js, Express, Fastify, etc.)
   • Test runner (vitest, jest, pytest, etc.)
   • Linter/formatter configuration

1C. Change History

For skills/agents that exist in both locations, use git log to understand the evolution of changes on each side. This is critical for understanding why things diverged, not just what differs.

Plugin side (always available):

1. Git log per skill/agent — For each matching skill/agent:

   git log --oneline --since="<target-last-modified>" -- skills/<name>/
   

   This shows commits in the plugin since the target's version was last updated.
2. Commit message analysis — Read commit messages to understand the intent behind changes (bug fixes, new features, refactors). This helps decide whether updates are worth migrating.

Target project side (if git available):

1. Git log per skill/agent — For each matching skill/agent:

   git -C <target-path> log --oneline -- .claude/skills/<name>/ .claude/agents/<name>.md
   

   This shows the full history of how the target's version evolved — revealing local adaptations, bug fixes, or improvements made in-context.
2. Commit message analysis — Understand whether changes were intentional customizations (should be preserved) or drift from the plugin source (may need realignment).

Content diff — For each matching skill/agent, use diff or read both files to identify:

• Structural changes (new sections, removed sections)
• Instruction changes (workflow updates, new rules)
• Tool/permission changes (new allowed-tools, model changes)
• Reference file additions or removals

Interpreting history for migration decisions:

• Target has local fixes/improvements not in plugin → candidate for from backport
• Plugin has updates the target hasn't received → candidate for to update
• Both sides changed the same section independently → flag as diverged, needs user decision
• Target intentionally removed a section → preserve that decision, don't re-add

1D. Research (as needed)

Use WebSearch and WebFetch to look up documentation when:

• The target project uses frameworks/tools this plugin's skills reference that need adaptation
• You need to understand a deployment platform's CLI or MCP integration
• You need current best practices for adapting patterns to a different stack
• The target project uses infrastructure you're not familiar with

Phase 2: Analysis

For to Direction (Plugin → Project)

Classify each plugin skill/agent into one of these categories:

Relevance Assessment for New Skills:

Adaptation Analysis:

For each skill marked "Needs Adaptation", identify:

• MCP tool name changes (e.g., mcp__linear__* → mcp__jira__* or GitHub Issues API)
• Build/test/lint command changes (e.g., npm test → bun test, pytest)
• Framework-specific patterns (e.g., Next.js → Express route conventions)
• File path conventions (e.g., src/ → app/, test file co-location vs separate directory)
• Agent model/tool adjustments for different project needs

For from Direction (Project → Plugin)

For each skill/agent in the target project:

When evaluating improvements:

• Compare instruction quality (more thorough? better error handling?)
• Check for new workflow steps or patterns
• Look for bug fixes or edge case handling
• Identify new reference docs that could benefit the plugin
• Note any project-specific hardcoding that would need to be generalized

Phase 3: Migration Proposal

Present a structured proposal to the user and start an interactive conversation.

Proposal Format

## Migration Proposal: [to|from] [project-name]

### Summary
- Direction: [to project / from project]
- Plugin skills: [count] | Plugin agents: [count]
- Target skills: [count] | Target agents: [count]
- Actions proposed: [count new] | [count updates] | [count skipped]

### Proposed Actions

#### New (will be created)
1. **[skill-name]** — [why it's relevant] → [any adaptations needed]

#### Updates (newer version available)
1. **[skill-name]** — [what changed] → [adaptation notes]

#### Skipped
1. **[skill-name]** — [reason: up to date | not applicable | project-specific]

### Adaptations Required
[For each skill needing adaptation, explain what changes and why]

### Questions
[Any decisions that need user input]

Interactive Conversation

After presenting the proposal, engage in conversation with the user:

1. Confirm scope — Which skills/agents to migrate, which to skip
2. Resolve adaptations — For each skill needing changes, confirm the approach
3. Address questions — Answer user questions about any proposed changes
4. Handle edge cases — Discuss skills where the right action isn't clear

Use AskUserQuestion for structured choices. Use regular conversation for open-ended discussion.

Do NOT proceed to execution until the user explicitly confirms.

Phase 4: Execution

For to Direction

For each confirmed skill:

1. Create directory — <target-project>/.claude/skills/<name>/
2. Write adapted SKILL.md — Apply all confirmed adaptations:
   • Replace MCP tool names in allowed-tools and instructions
   • Update command references (test, build, lint)
   • Adjust file path conventions
   • Update framework-specific patterns
   • Preserve the skill's core logic and workflow
3. Copy/adapt references — Process each reference file similarly
4. Write adapted agents — <target-project>/.claude/agents/<name>.md

For each confirmed agent:

1. Write adapted agent file — Apply model, tool, and permission adaptations

After all files are written: 5. Update target CLAUDE.md — If it has a skills/agents table, update it. If not, suggest adding one. 6. Verify — Read back each written file to confirm it was written correctly

For from Direction

For each confirmed improvement:

1. Update plugin skill — Edit the SKILL.md in this repository
2. Update references — Add, modify, or remove reference files
3. Update plugin agents — Edit agent files in this repository
4. Generalize — Remove project-specific references, use dynamic discovery patterns

After all files are updated: 5. Update plugin CLAUDE.md — Update the skill/agent tables if they changed 6. Verify — Read back each modified file

Adaptation Patterns

When adapting skills to a different tech stack, apply these transformations:

Issue Tracker Adaptation:

• Linear → Jira: Change mcp__linear__* tool names, adjust state names, update field mappings
• Linear → GitHub Issues: Use gh CLI instead of MCP tools, map labels/milestones
• If no issue tracker: Remove issue creation steps, keep planning output in PLANS.md only

Test Runner Adaptation:

• vitest/jest → pytest: Change file patterns, assertion syntax references, config file names
• Adjust verifier agent commands accordingly

Deployment Adaptation:

• Railway → Vercel/AWS/GCP: Change MCP tool names, adjust deployment commands
• If no deployment MCP: Remove deployment checks, simplify push-to-production

Language Adaptation:

• TypeScript → Python: Change file extensions in Glob patterns, adjust import conventions
• TypeScript → Go/Rust/etc.: Significant restructuring may be needed — flag for user review

Framework Adaptation:

• Next.js → Express/Fastify: Change route conventions, middleware patterns
• React → Vue/Svelte: Change component conventions in frontend-review

Error Handling

Rules

• Never migrate tools-migrate itself — This skill stays in the plugin only
• Never overwrite without confirmation — Always show what will change before writing
• Preserve target customizations — When updating, merge changes rather than overwrite
• Generalize when pulling back — Remove project-specific references when migrating to plugin
• Adapt, don't copy — Skills must work in the target's architecture
• Research when uncertain — Use WebSearch for framework/tool documentation
• One direction per invocation — Either to or from, not both

Termination

After execution completes, output:

## Migration Complete

**Direction:** [to|from] [project-name]
**Skills migrated:** [count] ([count] new, [count] updated)
**Agents migrated:** [count] ([count] new, [count] updated)
**Skipped:** [count] ([reasons])
