check

check is a skill for Claude Code, Codex from ffroliva/gflow-cli. It costs 20 tokens per session (2,696 once invoked), scanned A, original, MIT.

A repository quality-check workflow that fixes lint and formatting problems, then checks documentation, types, and tests. Lint and formatting checks look for code issues and consistent style.

In plain words
What is it for?
Use it before every commit to run repository checks, repair supported style issues, verify documentation links and generated docs, and report failures in types or tests.
Why use it?
It catches problems before a commit and checks the same quality rules used by continuous integration, the automated system that tests changes.

Which agent this was written for is unclear — built for aider. Also seen: mentions AGENTS.md; mentions Codex; built for aider.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is PYTHONUTF8=1 uv run python scripts/ci/check_repo_hygiene.py.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

    Skill enumerates or reads other installed skills. Access to other skills' SKILL.md files or the skills directory reveals prompt instructions, capabilities, and secrets that should be invisible to peer skills.

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

check 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 1mo ago.

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.

How it starts

The opening of the file, as written. The whole thing — 196 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/gflow:check — Quality gates

Run in order. Stop and report if a step fails after the fix pass.

Steps

These steps mirror the CI test job in .github/workflows/ci.yml in the same order. Any command that CI runs as a verify (--check) is run here as a verify too — see step 4.

1. Repo hygiene + doc links + website-docs PII guard (read-only — CI runs all three; a broken doc link or a private identifier in the published website/docs/ mirror fails CI)

PYTHONUTF8=1 uv run python scripts/ci/check_repo_hygiene.py
PYTHONUTF8=1 uv run python scripts/ci/check_doc_links.py
PYTHONUTF8=1 uv run python scripts/ci/check_website_docs_pii.py
PYTHONUTF8=1 uv run python scripts/ci/generate_website_docs.py --check
PYTHONUTF8=1 uv run python scripts/ci/check_council_memory.py

generate_website_docs.py --check fails on either half of the published-site contract:

  • DRIFT: — canonical docs/ changed but the website/docs/ mirror was not regenerated. Fix with uv run python scripts/ci/generate_website_docs.py and stage website/docs/.
  • NAV-ORPHAN: — a page is published but no nav: entry in website/mkdocs.yml points at it, so it is live but unreachable. Add the entry under the right nav section.

1b. Surface blast radius — MCP↔CLI parity and the other mirrors (read-only; MANDATORY whenever the change touches a CLI command, option, flag help text, exit code, or user-facing error string)

tests/mcp/test_cli_parity.py is a command-level gate only: it asserts every CLI leaf has a mapped MCP tool or a stated exemption. It is green while a new --option goes unmirrored, and green while an MCP docstring asserts a restriction the CLI no longer has. That semantic drift is invisible to every automated gate in this file, so it is checked here by hand — deliberately, because the alternative is shipping it.

PYTHONUTF8=1 uv run python -m pytest -q tests/mcp/test_cli_parity.py tests/mcp/test_server.py

Then enumerate the blast radius. For the CLI symbol(s) you changed (option name, model alias, exit code, capability), grep the whole repo and confirm every hit is either updated or still true:

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.

check is a skill published in the GitHub repository ffroliva/gflow-cli (298 stars, last pushed yesterday), licensed MIT. It adds 20 tokens to every session and 2,696 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
