evolve-crux skillA
evolve-crux is agent-read markdown (skill) from mehdiforoozandeh/crux: 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 — add.
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns 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`? …
