Implementation Planning

Critical rules

  • NO IMPLEMENTATION WITHOUT A PLAN FIRST for multi-step work.
  • Assume the executor has zero codebase context: exact paths, complete code, exact commands with expected output.
  • Every task: test → fail → implement → pass → commit. One action per step (~2-5 min).
  • Never vague steps, skipped verification, bundled multi-file "and" steps, or assumed knowledge.
  • Save to docs/plans/YYYY-MM-DD-<feature-name>.md. Prefer fn(args, deps) and Result types.
  • Before drafting task bodies, read references/plan-structure.md.

Workflow

  1. Confirm design is approved (design-exploration) when requirements were ambiguous.
  2. Write header: goal, architecture, tech stack.
  3. Break into bite-sized TDD tasks with exact files and copy-pasteable code (see plan-structure).
  4. Quality-check: one action, exact paths, complete code, expected command output, clear TDD, commit messages.
  5. Save under docs/plans/ and offer execution handoff (often inside git-worktrees).

Resources

Validation

  • [ ] Header has goal, architecture, tech stack
  • [ ] Every task follows test → fail → implement → pass → commit
  • [ ] Exact paths; commands state expected output; no bundled steps
  • [ ] Plan saved to docs/plans/ and ready for handoff

Constraints

  • Skip for single-file/single-function obvious scope.
  • Related: design-exploration, tdd-workflow, git-worktrees, parallel-agent-dispatch, create-tasks.
