build-check SKILL.md skillA

Removed from GitHub on 2026-11-09. The file no longer exists in its repository, and every version below is still saved here. mdr add no longer finds it by name, but a lockfile that pins one of these versions still installs it from its recorded commit, for as long as GitHub keeps that commit.

build-check from arcasilesgroup/ai-engineering is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Pins the contents saved here, the only way to install this file now it is gone from GitHub. What a pinned install does.

Run the project's objective quality gates — typecheck, lint, tests, and a production build, whatever this project actually uses — then diagnose any failure down to the file and root cause. Use before committing, opening a PR, or declaring work done, and whenever asked whether the code compiles, typechecks, lints, tests, or builds.

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

# Build check

The machine's verdict, not an opinion. Everything here either passes or fails,
and a failure is never a judgment call. Run this **before** the reasoning-based
reviews — reviewing code that does not compile wastes effort on a file that is
about to change.

Fast, deterministic, and the highest-value-per-token check in the set.

Read `.claude/review/CONVENTIONS.md` first — §1 for stack detection, §3 for scope
(you need it to tell a pre-existing failure from one this change introduced), and
§6 for where the report goes. Your report format differs from the other skills'
by design: this one reports gates and failures, not severity-ranked findings.

## 1. Discover the gates — never assume them

Do **not** run commands from memory or from a template. A guessed command that
does not exist wastes a minute and produces a scary error that is not a finding.

Read the project's own definition of its gates, in this order:

1. **`CLAUDE.md` / `AGENTS.md`** — if the commands are written down, use exactly
   those and skip the rest of this discovery.
2. **The manifest's script block** — `package.json` `scripts`, `Makefile`
…

Read the whole file at its exact version.

How to install

The exact contents, by fingerprint

The line at the top of this page is already the fingerprint pin, because a file GitHub no longer serves cannot be found by its label. With it 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.
