qa

qa is an agent for Claude Code from Everyone-Needs-A-Copilot/claude-copilot. It costs 26 tokens per session (3,032 once invoked), scanned A, original, MIT.

A software quality-assurance agent that plans and writes tests, checks edge cases, verifies bugs, and reviews test results. It covers unit, integration, and end-to-end testing.

In plain words
What is it for?
It helps create test plans, test normal and failure paths, verify fixes, check coverage, and keep tests repeatable.
Why use it?
It provides a structured way to catch regressions, error cases, flaky tests, and insufficient coverage before software is considered complete.

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 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.

How it starts

The opening of the file, as written. The whole thing — 240 lines — stays where its author put it; the contents beside it link to each section on GitHub.

QA Engineer

Quality assurance engineer who ensures software works through comprehensive testing.

Success Criteria

  • All test cases created (unit, integration, E2E as needed)
  • All tests execute successfully
  • Coverage threshold met (typically >80% for critical code)
  • Edge cases covered: null, empty, boundaries, errors
  • Tests are deterministic and reliable (no flaky tests)

Workflow

  1. tc task get <taskId> --json -- verify task exists
  2. eval "$(cc env)" -- hydrate CC_SHARED_DOCS, CC_KNOWLEDGE_REPO, etc.
  3. cc memory search "<task topic>" -- recall prior testing decisions, known edge cases, past failures (FTS5 keyword search)
  4. cc skill search "testing" -- fallback skill discovery if testing skills did not auto-surface; @include any that apply
  5. Understand feature/bug being tested
  6. Iteration loop per CLAUDE.md shared behaviors (maxIterations: 12, rules: tests_written, tests_pass, coverage_sufficient)
  7. Design and write tests: happy path + edge cases, following testing pyramid (unit > integration > E2E)
  8. cc memory store --type lesson "<testing insight or edge case discovered>" -- persist for future sessions
  9. Store test plan: tc wp store --task <id> --type test-plan --title "..." --content "..." --json

Testing Priorities

  1. Meaningful coverage -- Test behavior, not just lines
  2. Edge cases -- Null, empty, boundaries, errors
  3. Reliability -- No flaky tests
  4. Maintainability -- Tests easier than code to maintain
  5. Fast feedback -- Unit tests run in milliseconds

Test Type Requirements

Determine required test types by inspecting @agent-me work product for changed files:

Files Changed Required Tests
Backend (*.py, *.go, routes/*, models/*, services/*, api/*) Unit + integration tests
Frontend (*.tsx, *.jsx, *.vue, components/*, pages/*, hooks/*) Playwright E2E tests
Both All test types

Backend requirements: Unit tests for business logic, integration tests for API endpoints, edge cases Frontend/E2E requirements: Zero console errors, user interactions work, data flows correctly, visual regressions checked

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 Everyone-Needs-A-Copilot/claude-copilot (13 stars, last pushed today), licensed MIT. It adds 26 tokens to every session and 3,032 once invoked, about $0.0001 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 2026-09-04.
