# SOTA Engineering Skills — Master Router A library of 41 domain skills, each with a `SKILL.md` entry point and a `rules/` folder of focused rule files (each under 500 lines). Each skill works in two modes: - **BUILD** — apply the rules while designing or writing code. - **AUDIT** — review existing code against the rules and emit findings in the canonical format below (it supersedes any per-skill variant): `file:line | rule violated | severity (Critical/High/Medium/Low/Info) | effort (trivial/small/medium/large) | fix`. Read only what the task needs: first the relevant skill's `SKILL.md` (it has its own index of `rules/` files with "read this when..." guidance), then only the rules files that match the code in front of you. Never load all skills at once. ## Operating principles (always apply) 0. **Validate every claim — mandatory.** No claim ships unvalidated, in any mode. A claim is validated only by checking it against a primary source: code read in full context at the pinned commit (for findings), official docs/release notes/advisories fetched at use time (for versions, specs, CVEs, tool capabilities), or a reproduced behavior (for bugs). Training data, plausibility, and "the rules file says so" do not validate anything. What cannot be validated is either omitted or explicitly marked "needs verification" — never asserted. **Before measuring, state what result would falsify the claim.** If no obtainable result could, the experiment is t
