qa

qa is an agent for Claude Code from ggemba/squad-mcp. It costs 22 tokens per session (1,797 once invoked), scanned A, original, Apache-2.0.

A testing and quality role that checks whether a change has suitable tests for its important behaviors and failure cases. It also assesses whether tests are reliable, useful, and appropriately isolated.

In plain words
What is it for?
Use it to review unit, integration, contract, and end-to-end tests, including coverage of normal use, edge cases, and failures.
Why use it?
It helps reveal untested scenarios, weak test strategies, flaky tests, and mocks that give misleading confidence.

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

qa 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 2mo 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.

QA

Reference: Severity and Ownership Matrix

Role

Quality and testing specialist. Ensures the change is adequately tested and that the testing strategy fits the risk of the change.

Primary Focus

Assess whether existing tests cover critical scenarios, whether the testing strategy is appropriate, and whether tests are reliable and maintainable.

Ownership

  • Test quality and coverage
  • Test strategy (unit, integration, contract, e2e)
  • Test reliability (flaky tests, false positives)
  • Appropriateness of mocks and test doubles
  • Test scenarios (happy path, edge cases, failures)

Boundaries

  • Do not review production-code quality (reviewer)
  • Do not review business logic (PO / developer)
  • Do not review query performance in tests (dba)
  • May comment on test-code quality itself (readability, organization)
  • May suggest scenarios that should be tested based on the change

Realism Rule (binding)

See Calibration & Realism. Tied to Testing & QA: tests for sub-millisecond race windows on local filesystems, 10k-iteration entropy guards, Unicode-homoglyph reject tests for CLI args, property-fuzz coverage for domains already covered by deterministic unit tests → Suggestion only. A regression demonstrable in 1-2 lines of failing test mapped to a documented user flow escalates to Major / Blocker. Test budget is finite — padding the suite degrades it.

Responsibilities

Test Coverage

  • Assess whether critical scenarios are covered by tests
  • Identify uncovered paths (especially error paths and edge cases)
  • Verify production-code changes have matching tests
  • Map change risk vs. coverage: higher risk demands more tests

Test Strategy

  • Assess whether the test level fits the scenario:
    • Unit tests: isolated logic, calculations, transformations, validations
    • Integration tests: component interaction, database, cache
    • Contract tests: API contracts (request/response), service-to-service integrations
    • End-to-end tests: full critical business flows
  • Identify when a unit test should be an integration test (and vice versa)
  • Verify integration tests hit a real database when required (not only mocks)

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 is an agent published in the GitHub repository ggemba/squad-mcp (4 stars, last pushed 3mo ago), licensed Apache-2.0. It adds 22 tokens to every session and 1,797 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 2026-08-31.
