# Explore → Plan → Code → Verify Separate research from execution so you don't build the wrong thing. 1. **Explore (read-only).** Enter plan mode or use the `scout` subagent. Read the relevant files and existing patterns. Answer: where does this live, what conventions apply, what will change. No edits yet. 2. **Plan.** Produce a concrete plan naming the exact files/interfaces to touch, what's out of scope, and an end-to-end verification step. For big features, interview the user with `AskUserQuestion`, then write it to `SPEC.md` and start a fresh session to implement against it. 3. **Code.** Implement against the plan. Follow existing patterns; add no new deps without cause. 4. **Verify.** Run the check (tests/build/lint) and show the output. For risky diffs, hand to the `verifier` subagent. Iterate until it actually passes — don't assert success without evidence. Skip this whole flow for one-line or obviously-scoped fixes; the ceremony isn't worth it there.
