quality-gate

quality-gate is a skill for Claude Code, Codex from LuisFelipeMoro/Harness-devkit. It costs 57 tokens per session (387 once invoked), scanned A, original, MIT.

A read-only checklist that checks whether a code project is ready to ship. It detects the programming stack and reports PASS or FAIL for formatting, types, linting, builds, tests, coverage, and other applicable checks.

In plain words
What is it for?
Use it before handing over code or opening a pull request to run the project's quality checks and see the overall verdict.
Why use it?
It replaces a scattered set of manual checks with one ordered report and makes a failed check block the handoff.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

quality-gate scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured today.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Every gate must pass before handoff; a single failing gate blocks the handoff.

Contract

  • Input: a working directory containing source code.
  • Output: a report table with one PASS/FAIL row per gate plus an overall verdict line.
  • Tool boundary: read-only verification; source files stay unmodified, never auto-fixed.
  • Done when: the report table prints with an overall verdict line and a coverage figure.

Steps

  1. Detect the stack from the markers in references/stack-detection.md. Monorepos match every stack present.
  2. For each detected stack, the gate commands in references/quality-gate-reference.md apply in the fail-fast order from references/execution-and-report.md: format, type/vet, lint, build, tests + coverage, race (Go), vulnerability scan. Duplication (≤ 3%) runs once for the whole repo regardless of stack — it is language-agnostic, and a duplicate passes every other gate in the list.
  3. Tests + coverage is the mandatory sensor: every changed source file wants a corresponding test, and coverage below threshold counts as a failing gate.
  4. The report table and overall verdict line follow the template in references/execution-and-report.md. The verdict line states PASS when every gate is green.

References

  • references/stack-detection.md — detection command and file→stack table.
  • references/execution-and-report.md — gate order and report template.
  • references/quality-gate-reference.md — per-stack gate commands and common fixes.
Files

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
