| description | Turn an approved task-analysis result into a shared technical design and coding-ready implementation handoff. Use when Codex has an existing task folder under `tmp/tasks/`, plus a selected solution and related codebase research, and needs to produce `implementation-plan-X.md` and `coding-task-X.md` before writing code. |
Implementation Plan
Use this skill when the design direction is already chosen and the next missing artifact is a coding-ready plan.
Workflow
Follow the canonical workflow in ../../../.memory-bank/workflows/implementation-plan.md.
Required Guardrails
- Read the existing task folder artifacts first, especially
task.md and the selected solution.
- Re-check the current code, tests, configs, and schema paths instead of trusting earlier analysis blindly.
- Treat this as a handoff-preparation step, not a fresh solution-comparison step.
- If the chosen direction is ambiguous or stale enough to change the recommendation, stop and route the task back to analysis.
- Write the outputs into the existing
tmp/tasks/<task-name>/ folder as implementation-plan-X.md and coding-task-X.md.
- After drafting
implementation-plan-X.md, stop for user review and do not write coding-task-X.md until the user confirms the plan.
- If the user requests changes to the plan, update
implementation-plan-X.md and repeat the review loop.
- Keep the implementation plan focused on shared technical design; keep the coding task focused on actionable execution details.
Minimal Starting Reads
Start with:
../../../.memory-bank/project-context.md
../../../.memory-bank/architecture.md
../../../.memory-bank/exploration-map.md
../../../.memory-bank/gotchas.md
../../../tmp/tasks/<task-name>/task.md
../../../tmp/tasks/<task-name>/solution_*.md
../../../tmp/tasks/<task-name>/solutions.md if present
Then read the specific research notes, ADRs, rules, tests, and source files needed to make the design concrete and current.
