Sashiko Feature Creation Skill

Core Workflow

Follow this structured process for every feature implementation request:

1. Analysis & Discovery

• Read Baseline: Read GEMINI.md to identify project-wide constraints, coding standards, and mandatory practices.
• Detect Design Docs: Search the designs/ directory for documents relevant to the feature request. If multiple docs seem relevant or none are found, ask the user for clarification.
• Investigate Codebase: Invoke the codebase_investigator on the modules likely to be affected. Determine:
  • Existing paradigms and data structures.
  • Integration points.
  • Potential impacts on other system components.

2. Planning

• Propose a step-by-step implementation plan.
• Commit Strategy: Plan to split the work into small, logical, and self-sufficient commits.
• Principles Alignment: Reference references/principles.md to ensure the proposed design adheres to SOLID/DRY principles in a Rust context.

3. Implementation & Iterative Validation

• Execute the plan one step at a time.
• Standard Adherence: Adhere strictly to idiomatic Rust (v1.90 compatibility) and the rules in GEMINI.md.
• Continuous Checking: After every iteration of code changes:
  • Run make lint for formatting and clippy checks.
  • Run make test for unit testing.
  • Run make check-pr before completing a task to ensure all CI-level checks pass.
• Sign-off: All commits must be signed-off (git commit -s).

4. Final Review

• Summarize the changes against the original request.
• Verify that no temporary logs or files are left behind.
• Ensure the final state of the repository is clean.
