ccc-qa

A software testing workflow that checks unit tests, integration tests, and end-to-end tests before release. It also reviews test coverage, unusual cases, and unreliable tests.

In plain words
What is it for?
Use it for release checks, full test-suite runs, coverage reviews, finding missing edge-case tests, and identifying flaky tests—tests that fail unpredictably.
Why use it?
It brings results from several kinds of tests into one review and highlights important gaps or failures before code ships.

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

ccc-qa scanned grade A with 1 finding 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 3d 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.

$ccc-qa — Comprehensive QA Workflow

Full QA pass before shipping. Detects test framework, runs all suites, reports coverage delta, flags edge cases and flaky tests. Delegates analysis to the qa-engineer subagent. Never marks QA passed with open 🔴 Critical findings.

Triggers

  • $ccc-qa or /qa
  • "QA pass", "run all tests", "test coverage check"
  • "before shipping", "pre-release checks", "is this ready to ship"
  • "check test coverage", "find missing tests"
  • "flaky test", "test suite health"
  • Coming from $ccc-review or $ccc-ship

When NOT to Use

  • Greenfield project with no tests yet — use $ccc-testing to scaffold the test suite first
  • Single-function bug fixes where a targeted unit test is the right move (write it directly)
  • Pure documentation or config-only changes with no testable behavior

Process

Step 1 — Detect test framework

Run the following in parallel via Bash:

# Detect JS/TS frameworks
cat package.json 2>/dev/null | grep -E '"(vitest|jest|playwright|mocha|cypress|jasmine)"' | head -10

# Detect config files
ls *.config.{ts,js,mjs} vitest.config.* jest.config.* playwright.config.* pytest.ini setup.cfg \
   go.mod Cargo.toml pom.xml 2>/dev/null

# Detect Python
python3 -m pytest --collect-only -q 2>/dev/null | tail -5

# Detect Go
go test ./... -list '.*' 2>/dev/null | head -10

# Detect Rust
cargo test --no-run 2>/dev/null | tail -5

# Baseline coverage (if previously run)
cat .ccc/coverage-history.json 2>/dev/null || cat coverage/coverage-summary.json 2>/dev/null | head -30

Detection logic:

  • vitest.config.* present → Vitest (npx vitest run --coverage)
  • jest.config.* present or "jest" in scripts → Jest (npx jest --coverage)
  • playwright.config.* present → Playwright (npx playwright test)
  • pytest.ini or setup.cfg [tool:pytest]pytest (python3 -m pytest --cov)
  • go.mod present → Go test (go test ./... -cover)
  • Cargo.toml present → cargo test (cargo test 2>&1)
  • pom.xml present → JUnit via Maven (mvn test)
  • None detected → report to user and offer to scaffold via $ccc-testing

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.

ccc-qa is a skill published in the GitHub repository KevinZai/commander (6 stars, last pushed 3d ago), licensed MIT. It adds 36 tokens to every session and 2,361 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
