dev-plan

Create a concrete implementation plan from a spec or clearly scoped request before coding. Use for implementation-planning requests such as 出个 plan, 技术实施方案, plan this, or consensus plan. Ground steps in the repository and scale tradeoff analysis and independent review to risk. Clarify material requirement gaps when needed; do not force an intake workflow for already clear scope. Supports --quick and --deliberate.

# Dev Plan

Produce an implementable, verifiable plan within the user's stated scope. Planning does not authorize implementation. Read [references/dev-baseline.md](references/dev-baseline.md).

## Establish the contract

Read the supplied spec or related `.claude/artifacts/designs/<feature>.md`, relevant code, existing tests, and any accepted ADR. Preserve source links, acceptance criterion identifiers, scope exclusions, assumptions, and open questions. A clear request is sufficient without a separate spec artifact; summarize its requirements in the plan.

If a missing requirement materially changes the solution, ask for that decision or explain the blocked portion. Use `dev-grill-docs` when the task actually requires broader requirement alignment and that skill is available. Continue planning independent parts. Do not require a new intake invocation merely because a spec file is absent. A `STUCK` source must have its blocking questions resolved before planning dependent implementation.

Inspect actual definitions and call paths before naming modification targets. New paths must be labeled proposed. Cite existing paths and symbols; use line numbers only when verified and helpful. Do not manufacture precision or require a percentage of steps to contain line numbers.
