A2UI Implement Feature from Blueprint Skill

This skill provides step-by-step instructions on implementing feature specifications and updating codebase module compliance commit hashes.

---

1. Implementation Workflow

Step 1: Check Codebase Status & Context

• Open the target codebase's blueprint at blueprints/codebases/<relative_path>/codebase.blueprint.md.
• Identify the target associated_module and module_blueprint_commit.
• Check if the codebase needs to catch up to the latest Module Blueprint commit:

  git diff <module_blueprint_commit>..HEAD blueprints/modules/<associated_module>.blueprint.md
  

• If implementing an optional feature blueprint from blueprints/features/<feature_name>.blueprint.md, check its dependencies list first.

Step 2: Execute Implementation & Conformance Tests

• Implement required code changes in the target codebase directory (<relative_path>).
• Run local unit and conformance tests specified by test_command in codebase.blueprint.md.

Step 3: Update Codebase Blueprint Compliance

• Open blueprints/codebases/<relative_path>/codebase.blueprint.md.
• If you brought the codebase up to date with the latest Module Blueprint commit, update module_blueprint_commit to the current commit hash:

  git log -n 1 --pretty=format:%H blueprints/modules/<associated_module>.blueprint.md
  

• If you implemented an optional feature from blueprints/features/, add its name to implemented_features.

Step 4: Validate Blueprints

Verify blueprint consistency across the monorepo:
