Build
Implement code changes and features from a detailed implementation plan. This skill reads a plan file, follows its instructions step-by-step, and reports the completed work.
Prerequisites
- A plan file in markdown format (typically from
/quick-plan skill)
- The plan contains clear implementation steps
- You have access to the files that need to be modified
Workflow
- Validate plan - Confirm a plan file path has been provided
- Analyze plan - Read the plan and understand all implementation requirements
- Implement - Execute each step of the plan, modifying code as needed
- Report - Summarize changes and show diff statistics
Instructions
- If no plan file path is provided, ask the user to provide it and stop
- Read the plan file thoroughly - understand the full scope of work
- Think deeply about the implementation approach before starting
- Execute the plan step-by-step:
- Create new files as specified
- Modify existing files as outlined
- Follow code patterns and conventions from the plan
- After implementation, report:
- Summary of completed work (bullet points)
- Files changed with
git diff --stat
Examples
Example 1: Building from a plan
User: /build specs/authentication-system.md
Claude: [Reads authentication-system.md plan]
[Implements all steps]
Summary:
- Created JWT middleware in src/middleware/auth.ts
- Added login endpoint to src/routes/auth.ts
- Added password hashing utilities
[Shows git diff --stat output]
Example 2: Implementing a feature plan
User: Build the payment integration from specs/stripe-integration.md
Claude: [Reads plan and implements stripe integration]
Summary:
- Integrated Stripe API client
- Created payment endpoints
- Added webhooks for payment events
