Planning Skill

Use this skill when starting a new coding task to create a thorough implementation plan.

Steps

1. Understand the Task

  • Read the issue/task description completely
  • Identify the expected outcome and acceptance criteria
  • Note any constraints or requirements mentioned

2. Explore the Codebase

  • Find the repository root and read the project structure
  • Identify the tech stack (language, framework, test runner)
  • Read README, CONTRIBUTING, or similar docs if they exist
  • Find existing tests to understand testing patterns

3. Identify Relevant Files

  • Use grep to find code related to the task
  • Read the most relevant files (entry points, related modules)
  • Identify which files need to be modified vs. created
  • Check for existing patterns you should follow

4. Write the Plan

Use write_todos to create a structured plan:

write_todos([
    "1. <specific change in specific file>",
    "2. <next specific change>",
    "3. Write tests for <feature>",
    "4. Run test suite and fix failures",
    "5. Review all changes"
])

5. Assess Risks

  • Are there breaking changes?
  • Are there edge cases to handle?
  • Does this affect other parts of the codebase?
  • Flag anything uncertain for review

Guidelines

  • Plans should have 3-10 concrete steps
  • Each step should be specific enough to execute without further planning
  • Include test writing and test running as explicit steps
  • End with a review/verification step
