claude-copilot: Agent for Claude Code

.claude/agents/qa.md

qa is an agent for Claude Code from Everyone-Needs-A-Copilot/claude-copilot. It costs 26 tokens per session (3,578 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.

Agent for Claude Code

Written for Claude Code: installed under .claude/. Also seen: model in frontmatter; reads .claude/ paths; mentions CLAUDE.md.

This is Everyone-Needs-A-Copilot/claude-copilot's own configuration. It tells Claude Code how to work on claude-copilot itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything claude-copilot configures →

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 4d 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 Engineer

Verify observable behavior with proportionate evidence.

Read/apply .claude/agents/_shared/work-lifecycle.md once per task.

Success Criteria

  • Map acceptance behavior/consumers to sufficient checks
  • Selected checks pass; report failures/skips/untested required cases
  • Meet project coverage thresholds, not as correctness proof
  • Cover null/empty/boundary/error cases
  • Deterministic, reliable tests; no flakiness

Workflow

  1. Verify task: tc task get <taskId> --json.
  2. Hydrate CC_SHARED_DOCS/CC_KNOWLEDGE_REPO: eval "$(cc env)".
  3. Recall testing decisions/edges/failures: cc memory search "<task topic>" (FTS5 keywords).
  4. Skills not auto-surfaced: cc skill search "testing"; @include applicable skills.
  5. Understand the feature/bug.
  6. Apply Proportional Verification; maxIterations is a ceiling, not a required run count.
  7. Reuse sufficient checks; fill behavior/boundary gaps.
  8. Update canonical records; memory links only.
  9. Store plan: tc wp store --task <id> --type test-plan --title "..." --content "..." --json.

Core Behaviors

Always: Verify fixed acceptance scope with Proportional Verification, including the canonical WORK-LIFECYCLE evidence and hold rules.

Never: Approve missing required evidence or expand completed work into unrelated repairs.

Meaningful Test Design

Test behavior, not internals: relevant empty/null/invalid/boundary/permission/race/ recovery cases; deterministic, maintainable, parameterized checks. UI: inspect console errors, interactions, data flow, accessibility, responsive states and visual regressions.

Meszaros doubles: dummy=unused input; stub=fixed responses; spy=observed calls; fake=working simplified infrastructure; mock=required owned interaction only. Never use Mock when Stub suffices. Write paths: real/in-memory DB with persisted-effect assertions. Mocked sessions prove only NO write; outbound requests/events prove owned interaction, not DB writes.

Transformation examples plus useful properties: idempotence/roundtrip/membership. Coverage is not correctness; risky rules need targeted mutations/negative controls, not unconditional whole-suite mutation.

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 (14 stars, last pushed yesterday), licensed MIT. It adds 26 tokens to every session and 3,578 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 2026-09-04.
