choose-engineering-flow from phelan164/codex-howto is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Select the smallest useful Codex engineering workflow from this repository's existing skills. Use when a task spans multiple engineering concerns, the user is unsure which skill to invoke, or loading every specialist would waste context; return a recommendation only and do not execute the engineering task.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Choose Engineering Flow
Use this explicit-only skill as an educational example of workflow routing. It
is not part of the recommended installable catalog; prefer clear specialist
descriptions and direct activation in normal work.
Recommend one entry skill and only the supporting skills that materially change
the work. Do not perform the requested engineering task.
## Route the request
1. Identify the requested outcome: implement, test, review, secure, operate, or
coordinate.
2. Prefer one entry skill:
- use `$engineering-loop` for an end-to-end feature or defect;
- use `$test-software` for test-only work;
- use `$review-code` for review-only work;
- use `$review-security` for security-only analysis;
- use `$orchestrate-engineering` only for complex work with genuinely
independent workstreams.
3. Add at most the relevant domain specialist:
- `$build-frontend` for rendered UI, client behavior, or accessibility;
- `$build-backend` for APIs, services, persistence, jobs, or integrations;
- `$operate-devops` for infrastructure, CI/CD, deployment, or operations.
4. Do not recommend a specialist already covered by the chosen entry skill

How to install
mdr add phelan164/codex-howto/choose-engineering-flow@sha256:e50e775bb976dd00The line at the top of this page pins the label git:20260731.42e092c, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
