Use this skill when the task is a complex feature, a significant refactor, or has ambiguous requirements that benefit from a living plan.
Source of truth
The ExecPlan standard for this repo is in:
.codex/skills/lcp-execplan/references/PLANS.md
Workflow
- Read the full reference
PLANS.md above (it is intentionally strict).
- Create a single ExecPlan file as instructed (formatting rules matter).
- Keep the ExecPlan as a living document: update Progress/Decisions/Discoveries as you implement.
- Do not ask the user for “next steps” mid-execution; proceed milestone by milestone.
Acceptance
An ExecPlan is done only when it enables a complete novice (with only the repo + the plan) to reproduce a working, observable outcome.
