zyplux-cerberus 0.4.1

Cross-repo invariant verifier for the zyplux organization

cerberus

Verifies repository invariants — CI workflow structure, justfile and dependency conventions, CODEOWNERS, release-version bumps, and workflow secrets. Run it two ways: as a per-repo linter against a checkout (cerberus), or as a central scan across every repo in the org (cerberus org).

Requirements

• uv and Python 3.14
• gh, authenticated against the org — only for cerberus org

The justfile check shells out to just, which ships with the package (via rust-just) — no separate install.

Lint a repo

uv run cerberus            # lint the current directory
uv run cerberus PATH       # lint a checkout at PATH

Runs every check whose facts live in the checkout — the content and git-history scopes — and exits non-zero on any failure or error, so it drops into CI like any linter. Control-plane checks (workflow-secrets) read GitHub org/admin state the checkout cannot see, so they are skipped here and reported by cerberus org.

Run cerberus list to see every check, its scope, and what it verifies.

Option	Description
--check NAME	Limit to named check(s); repeatable
--config PATH	Use a cerberus.toml other than the bundled
--fix	Auto-fix fixable problems (e.g. trailing whitespace)

Scan the org

cerberus org takes the org as a required argument — a bare name, github.com/<org>, or a full URL.

uv run cerberus org zyplux                  # scan every repo, report findings
uv run cerberus org github.com/zyplux       # same, org given as a URL
uv run cerberus org zyplux --repo api       # scan only the named repo(s)

Runs all checks, including the control-plane ones the local linter skips. Accepts --repo/-r and --check. A failure or error exits non-zero.

Checks

ID	Scope	Verifies
justfile	content	Recipe names, aliases, check pipeline, wrapped tool calls, no trailing whitespace
ci-workflow	content	ci.yml exists, exposes a ci check, runs on PRs (push to main recommended)
ci-sequence	content	ci.yml runs the canonical check sequence per stack, in the org container
cerberus-step	content	A CI workflow runs cerberus to self-verify org invariants
workflow-tooling	content	Workflows set up only the workspace toolchain (uv, bun), not extra tools
rumdl-config	content	.rumdl.toml carries the org-canonical rule config (per-repo exclude allowed)
vitest-runner	content	TypeScript tests run on vitest, never bun's built-in test runner
ts-project-references	content	TypeScript typecheck runs via project references (tsc -b), not a per-package fan-out
catalog-discipline	content	Every workspace package.json dependency pins via catalog: or workspace:
release-bumps	git-history	A published target's version is bumped whenever its release surface changes
codeowners	content	CODEOWNERS present and covers /.github/
workflow-secrets	control-plane	Every secret referenced in workflows is provisioned

Config

Policy — org name, excluded repos, required recipes and aliases — lives in cerberus.toml. Override it with --config PATH.
