 ## 🎯 Purpose
 
-Code Quality Skills separates code-quality work into small, composable sub-skills. Choose a targeted skill when you need one type of review, or use the all-in-one bundle when a change needs the entire verification-and-cleaning workflow.
+These skills guide AI agents through an explicit delivery workflow and empower them to:

-## 🧩 Sub-skills
+## 🧭 Four-Stage Workflow
+
+Use [`skills/code-execution-skill/`](skills/code-execution-skill/) to coordinate every change through these ordered stages. Each stage has a required input and produces the handoff artifact required by the next stage.
+
+| Stage | Input | Output / handoff |
+| --- | --- | --- |
+| **1. Planning** | Change request and repository context | **Approved plan** covering scope, approach, risks, acceptance criteria, and planned checks. |
+| **2. Execution / Building** | Approved plan | **Implementation summary** recording completed work, changed files, build results, deviations, and known risks. |
+| **3. Verification** | Implementation summary and changed code | **Verification results** with lint, test, runtime, security, and reporting evidence. |
+| **4. Review** | Implementation summary and verification results | **Final review findings** with structural, security, and evidence-based disposition. |
+
+### Shared verification and review skill
+
+Both **verification** and **review** use the existing [`skills/code-verify-and-clean-skill/`](skills/code-verify-and-clean-skill/) skill. Do **not** move or rewrite that skill; it remains the shared source of truth.
+
+- **Verification** follows its linting, tests, runtime checks, security checks, and reporting workflow. Record the commands, outcomes, evidence, remaining risks, and proceed/return recommendation in the verification results.
+- **Review** follows its structural-cleanup standards, security-review guidance, [review template](skills/code-verify-and-clean-skill/assets/review-template.md), and verification evidence requirements. Record blocking issues, follow-ups, residual risks, and final disposition in the final review findings.
+
+A change is complete only after all four artifacts are preserved: approved plan, implementation summary, verification results, and final review findings.

+# Code Execution Skill
+
+Deliver code changes through four ordered stages: **planning**, **execution/building**, **verification**, and **review**. A stage may begin only when it receives the required handoff artifact from the preceding stage, and it must produce the artifact required by the next stage.
+
+## Shared Quality Skill
+
+Stages 3 and 4 both use the existing [`skills/code-verify-and-clean-skill/`](../code-verify-and-clean-skill/) skill. **Do not move, copy, rewrite, or otherwise modify that skill as part of this workflow.** Treat it as the shared source of truth for verification, cleanup, security, templates, and reporting.
+
+## Workflow and Handoffs
+
+| Stage | Required input | Required work | Required output / handoff |
+| --- | --- | --- | --- |
+| 1. Planning | Change request and relevant repository context | Define scope, affected files, implementation approach, risks, acceptance criteria, and commands/checks to run. Resolve open questions before implementation. | **Approved plan** |
+| 2. Execution / Building | Approved plan | Implement only the approved scope, make focused changes, and run the applicable build or generation steps. Record files changed, decisions, and any deviations from the plan. | **Implementation summary** |
+| 3. Verification | Implementation summary and changed code | Use `skills/code-verify-and-clean-skill/` to run its linting, tests, runtime checks, security checks, and reporting workflow. Capture commands, outcomes, failures, and remaining risks. | **Verification results** |
+| 4. Review | Implementation summary and verification results | Use `skills/code-verify-and-clean-skill/` to assess structural-cleanup standards and security-review guidance, complete its review template, and confirm verification evidence is sufficient for the change. | **Final review findings** |
+
+## Stage 1 — Planning
+
+Create an approved plan before editing implementation files. It must include:
+
+- Goal and non-goals.
+- Affected files/components and expected change sequence.
+- Risks, dependencies, and rollback considerations.
+- Clear acceptance criteria.
+- Expected build, test, lint, runtime, and security checks.
+
+**Handoff:** The approved plan is the only authorization for execution/building. If scope changes materially, update and re-approve the plan before continuing.
+
+## Stage 2 — Execution / Building
+
+Implement the approved plan in small, coherent changes. Build or generate artifacts as appropriate for the repository, and keep implementation notes accurate.
+
+The implementation summary must state:
+
+- The approved-plan items completed and any approved deviations.
+- Files changed and the purpose of each change.
+- Build/generation commands run and their outcomes.
+- Known limitations, deferred work, or risks to pass to verification.
+
+**Handoff:** Supply the implementation summary and changed code to verification.
+
+## Stage 3 — Verification
+
+Verification must use the existing [`skills/code-verify-and-clean-skill/`](../code-verify-and-clean-skill/) without moving or rewriting it. Follow that skill's established workflow for:
+
+1. **Linting and static checks** — run applicable formatters, linters, type checks, and compilation/build checks.
+2. **Tests** — execute relevant unit, integration, and other repository-native test suites.
+3. **Runtime checks** — when applicable, run the application and use its DevTools/browser guidance to inspect behavior, console output, and network requests.
+4. **Security checks** — apply its security-verification guidance for input handling, exposure risks, dependencies, and other relevant attack surfaces.
+5. **Reporting** — follow its reporting workflow and record findings and evidence using its supplied reporting assets where applicable.
+
+Verification results must include the exact commands/checks, pass/fail status, pertinent output or evidence, unresolved findings, and an explicit recommendation to proceed or return to execution/building.
+
+**Handoff:** Pass the verification results, together with the implementation summary, to review. Any blocking verification failure returns the change to Stage 2.
+
+## Stage 4 — Review
+
+Review must also use the existing [`skills/code-verify-and-clean-skill/`](../code-verify-and-clean-skill/) without moving or rewriting it. Review the implementation and verification evidence against that skill's:
+
+- **Structural-cleanup standards** for modularity, duplication, dead code, clarity, and maintainability.
+- **Security-review guidance** for vulnerabilities, unsafe handling, secret exposure, and residual risk.
+- **Review template** in `assets/review-template.md` to make findings consistent and actionable.
+- **Verification evidence** from Stage 3, confirming that checks are relevant, complete, and sufficient for the claimed behavior.
+
+Final review findings must identify approved items, blocking issues, non-blocking follow-ups, residual risks, and the final disposition: approve, approve with follow-ups, or return to execution/building.
+
+## Completion Rule
+
+A change is complete only after final review findings have been produced and the final disposition is approval (with any follow-ups explicitly recorded). Preserve all four handoff artifacts with the change record:
+
+1. Approved plan
+2. Implementation summary
+3. Verification results
+4. Final review findings
