build-skill	Implement features and changes from implementation plans. Takes a plan file path as input and executes the implementation steps, then reports changes. Use when you have a detailed plan document and need to code it up, or want to implement specifications written in markdown format.	Read, Edit, Write, Bash, Glob, Grep

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

1. Validate plan - Confirm a plan file path has been provided
2. Analyze plan - Read the plan and understand all implementation requirements
3. Implement - Execute each step of the plan, modifying code as needed
4. Report - Summarize changes and show diff statistics

Instructions

1. If no plan file path is provided, ask the user to provide it and stop
2. Read the plan file thoroughly - understand the full scope of work
3. Think deeply about the implementation approach before starting
4. Execute the plan step-by-step:
   • Create new files as specified
   • Modify existing files as outlined
   • Follow code patterns and conventions from the plan
5. 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
