Evolve crux itself — add a capability or fix a recurring flaw in the crux tool, end to end: ideate → build → validate → ship. Turns a feature idea or a "crux keeps doing X" annoyance into a signed-off PRD, a tests-first implementation, a hard validation gate (selftest green · stdlib-only · existing vaults still load · version/migration), and a pull request. Works for anyone contributing to crux, not just the maintainer; the maintainer self-merges and cuts releases. Use when working ON crux —…
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
# evolve-crux — ship a change to crux, rigorously This skill is for working **on crux the tool** (your clone of the crux repo), not on a research project that *uses* crux. It carries one change — a new capability or a fix for something crux keeps getting wrong — through a strictly gated arc: ``` ideate → build → validate → ship ``` Each stage has an **exit criterion**; you do not advance until it's met. The arc is the same whether the change is a one-line bug fix or a `.spec/` epic — only the ceremony scales. ## Who's driving (contributor-always) Assume **the person evolving crux is not the maintainer.** Because crux ships this skill to its users, everyone runs the *same* path and **ends at a pull request** — no auto-detection of who you are, no privileged branch. The maintainer is just the contributor who can **self-merge** their own PR, plus a small, separate **release** step (below). This keeps one code path and makes third-party PRs first-class. Work in a dedicated session **inside your crux clone** (a fresh chat, not the project you were researching). No clone yet — e.g. you installed the skills via `npx skills add`? …

How to install
mdr add mehdiforoozandeh/crux/evolve-crux@sha256:4f7ab493b99d217dThe line at the top of this page pins the label v1.0, 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.
