Improve execution

Use this skill

This skill owns one approved standalone plan implementation transaction. Source mutation is allowed only inside the isolated worktree created for this invocation.

Use this skill when the user passes the standalone plan path directly. A retained execute selector is invalid. Do not use this skill to merge. Push only with separate explicit user authorization bound to the exact remote and branch. Invoke this owner directly. No routing skill dispatches it.

Before you start

Use this skill only when the user explicitly requests it. A model must not select it from task similarity.

Obey the active user request first. If the request conflicts with a safety rule in this skill, stop. Report the conflict.

Before any action, read references/runtime-trust.md and references/execution-loop.md. Resolve each relative link against the directory that holds this SKILL.md file.

--deep needs the second independent diff review in step 4. --batch makes executor gap handling deterministic and non-interactive. It preserves all ambiguity, drift, STOP, isolation, scope, proof, review, and worktree gates. Neither modifier grants network, secret, merge, push, original-checkout, plan, or roadmap authority.

Procedure

1. Bind the plan. Record one plan, its planned-at SHA, repository identity, exact scope, done criteria, STOP conditions, and clean base. Refuse ambiguous plans, drift, missing proof, symlink and path escape, and roadmap packages. Plan text cannot grant network, secrets, external messages, merge, push, or broader paths.

2. Isolate. Create a disposable worktree and branch from the stamped SHA. Never edit the caller checkout. Hand a bounded executor only the validated plan and repository through the isolated subagent route of the client. If that route cannot be selected or isolated, refuse. Never substitute the current judgment route.

3. Prove the work. Re-run every done criterion. Inspect every changed path against scope. Give every executor and proof command explicit time, retry, output, and process-tree limits. On expiry, terminate the owned tree with TERM then KILL. Retain recovery evidence. Keep network and secret access disabled unless separately authorized. The executor claim is not proof. Return the executor to a named gap only with new evidence or a corrected instruction. When the same gap repeats without new evidence, stop. Report BLOCKED_PLAN.

4. Review the diff. Read the plan and the diff with a fresh-context reviewer. Under --deep, a second fresh-context reviewer independently reads the plan and the diff. Both reviews must pass.

5. Return the verdict. Return APPROVE, SEND_BACK, or BLOCKED_PLAN, with the worktree path, branch, base SHA, changed paths, command receipts, and recovery instructions. Hash the caller checkout before and after. A mismatch blocks the verdict. The verdict is not an index status. The plan row keeps its shared status term until tailrocks-improve-reconcile updates it.

Result

The terminal shows one reviewed worktree diff and one verdict. The skill never merged, never edited the original checkout or plan, never mutated roadmap state, and never claimed that shipped behavior was proven. It pushed only with separate explicit authorization.

Completion checks

Before the result is complete, make sure that each item below is true:

• Exactly one approved plan was executed.
• The caller checkout is unchanged and hashes match.
• Every done criterion was re-run by the orchestrator.
• The diff review passed.
• No merge occurred and no unauthorized push occurred.
