A pre-completion quality check for a software task. It finds which files changed and runs the relevant project checks through Make, such as linting, type checks, tests, or static analysis.

Use it before marking a task complete to verify backend, frontend, infrastructure, or documentation changes with the project’s applicable Make targets.

It prevents declaring work finished without checking the parts of the project that were affected. Failed checks are reported instead of hidden or skipped.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00066	$0.00575
Opus 5	$0.00033	$0.00287
Sonnet 5	$0.00013	$0.00115
Haiku 4.5	$0.00007	$0.00057

Security

Grade A, and why

qa-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 10d 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.

What it actually says

qa-check

A quality gate you run before declaring a task done. It is project-agnostic: it discovers what changed, maps that to the project's make targets, runs only the relevant ones, and reports Pass/Fail per check.

Git mechanics follow the git-flow core; this skill only adds the gate behaviour below.

How to run

Scope by the diff. git diff --name-only (vs the base/last commit) → decide which check sections apply (backend / frontend / infra / docs). Run only the sections touching changed paths. Everything goes through make.
Run the project's checks for that scope (lint → type/static analysis → unit → targeted functional/e2e). See ask-on-first-use for the mapping.
Report Pass/Fail per item. Green = the command exits 0 and introduces no new warnings. Red = stop and fix the root cause, then re-run.

Anti-patterns — never do these to make it "pass"

Do NOT skip or disable lint / type checks.
Do NOT mark tests skipped (@pytest.mark.skip, .skip, xfail, commenting out) without a real, stated reason.
Do NOT use --no-verify, and never silence failures with || true or by discarding stderr.
Do NOT run the whole suite (make test) unless the user asks — use the targeted form (name=<...>) for the modules you touched.
Do NOT auto-merge or auto-push because checks went green.

ask-on-first-use (per project)

On the first run in a project you don't know its commands. Ask the user (don't guess) and offer to save the answers to the project's .claude/ (a line in <project>/CLAUDE.md or a config file) so later runs skip the questions:

Path/module → make targets mapping (which lint + test targets cover which areas, e.g. backend vs frontend).
The minimal always-run command (e.g. make lint).
(optional) Coverage gate — threshold and where it's enforced.

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.

qa-check is a skill published in the GitHub repository Xakki/ai-agents-skills (6 stars, last pushed 19d ago), licensed MIT. It adds 66 tokens to every session and 575 once invoked, about $0.0003 per session on Opus 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 2026-08-31.

Claude Code Testing agentic-workflow ai-agents automation developer-tools kanban

taiyi-dev

A software-development stage that implements planned tasks using test-driven development, or TDD: write a failing test, make it pass, then improve the code. It checks the task plan, dependencies, file boundaries, and required completion evidence.

taiyi-test

A project workflow skill for verifying an implementation and producing a TEST.md record. TDD means writing a failing test, implementing the change, and then making the test pass; this skill checks that process and other regression cases.
