developer SKILL.md skillA
This file is byte-identical to the first copy the registry indexed, one of 3 indexed copies. Same content hash, so the same checks give both the same grade.
developer from crewrig/crewrig is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add crewrig/crewrig/developer@git:20261018.1588e62Pins git:20261018.1588e62 in mdr.lock. Pin the fingerprint instead.

Implementation skill for writing, modifying, and refactoring code. Activate by default for any coding task that does not warrant the architect skill. Optimized for parallelisable execution, fast feedback loops, and minimal surface area per change.
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
# Developer The default skill for implementation work. Deliver the smallest correct change, prove it works, and stop. ## When to activate - Any code change that fits inside one or a few files and does not cross a public contract. - Bug fixes with a known reproducer. - Refactors whose scope is bounded and reversible. Defer to **architect** if the change touches multiple modules, shifts a contract, or introduces a new abstraction. Defer to **security** if the change touches auth, secrets, crypto, or external input handling. ## Operating mode ### 1. Branch setup Before creating your branch, always synchronize with the remote to avoid basing work on a stale commit: ```sh git fetch origin git checkout -b <branch-name> origin/main ``` Never use `git checkout -b <branch> main` (local ref) — it may be behind `origin/main` if the remote was updated since your last fetch, which causes the branch to miss recently merged PRs and forces a rebase round-trip. ### 2. Read before writing Read the file you are about to modify. Read the function calling it. Read the tests around it. Two minutes of reading saves twenty minutes of guessing. …

How to install
mdr add crewrig/crewrig/developer@sha256:54e7940fb26a0f56The line at the top of this page pins the label git:20261018.1588e62, 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.
