Create A Plan

Use this skill when the user wants a substantive plan before a repository change.

Setup

Read ../_shared/references/prime-planning-workflow.md, ../_shared/references/state-and-config.md, and ../_shared/references/plan-artifact-template.md.
Initialize state with python3 scripts/optim_plans.py init --repo <target-repo> --topic <topic> --plan-level create-a-plan --request-text <original-request>.
Use .git/optim-plans for controller state and docs/optim-plans/YYYY-MM-DD-topic/ for public artifacts.

Depth Contract

Inspect the target Git repo read-only before the first product question.
Ask 5 to 10 planning questions, one at a time.
Use web research during brainstorming whenever outside library behavior, ecosystem precedent, UX convention, protocol semantics, or compatibility affects the recommendation.
Use the standard choice prompt format: recommended first, Other second-last, Auto-complete last.
Ask the mandatory final scope confirmation before writing PLAN_v1.md.
Write PLAN_v1.md under docs/optim-plans/YYYY-MM-DD-topic/.
Run up to five refinement rounds. Continue only for high-priority reviewer findings or unresolved criticizer questions.
In each refinement round, surface at most five high-priority comments or questions.
After convergence or user acceptance, ask the native execution handoff question without Auto-complete.

Fit

Choose this level for multi-file changes, architecture boundaries, user-facing workflows, external APIs, dependency upgrades, compatibility risk, or cases where web evidence should shape the plan.

Escalate to create-a-big-plan when the problem is open-ended, cross-system, strategically ambiguous, or likely to require more than ten planning decisions.
