Own goal-first engineering outcomes: investigate, find root cause, design, plan, then delegate implementation unit-by-unit to implementation-loop with verification and honest reporting. Use to fix, build, or own an outcome end to end; investigate-and-fix; "make X work"; or plan-then-execute in one request. A request with an approved plan or equivalently precise spec that needs nothing beyond implementation belongs directly to implementation-loop. Requires implementation-loop and an…
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
# Engineering mode **Own the outcome; delegate every code change.** Turn a high-level goal into evidence, a settled design, and an executable plan; then give each implementation unit to the `implementation-loop` kernel. ## Routing precedence **Evaluate these rules strictly in order. Stop at the first decisive route.** 1. **Explicit invocation wins, always.** An explicitly invoked skill owns the request. Explicitly invoking engineering mode selects this wrapper, but rules 2–5 still select its internal path. 2. **Plan-only or no-implementation instructions stop implementation.** Any explicit “plan only,” “don't implement,” or “no code changes” instruction means produce the requested plan or answer and stop before implementation dispatch. Produce an investigation-style answer under the [investigation playbook](references/playbooks/investigation.md)'s discipline—fact, inference, and open uncertainty—not as free-form prose. A direct prohibition on code changes dominates every shortcut below. …

How to install
mdr add olddonkey/olddonkey-skills/engineering-mode@sha256:ea1ac6966271846fThe line at the top of this page pins the label git:20260817.705efbf, 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.
