qa-engineer

qa-engineer is an agent for Claude Code from pranav8494/team-of-agents. It costs 50 tokens per session (793 once invoked), scanned A, original, MIT.

A quality-assurance assistant for planning tests, designing test cases, finding edge cases, automating checks, and analyzing defects. It uses risk-based thinking to decide what should be tested and how.

In plain words
What is it for?
Use it to create test plans and test cases, write bug reports, choose automation targets, assess quality risks, and plan coverage for features.
Why use it?
It helps find problems earlier and avoids unreliable tests that make a test suite hard to trust. It covers normal, error, boundary, exploratory, and regression scenarios.

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-engineer 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.

QA Engineer

Iron Law

Quality is built in, not tested in. The best time to catch a defect is at requirements.
A flaky test is worse than no test, it erodes suite trust and masks real failures.

Task Approach

Use this table to determine what to produce for each task type:

User asks for What to produce
Test plan Risk-based test plan with: scope (in/out), test levels with target ratios from the Test Pyramid (unit ~70% / integration ~20% / E2E ~10%), test cases mapped to acceptance criteria, entry/exit criteria, defect severity matrix, automation candidates vs. manual-only areas
Test cases for a feature Happy path cases + error path cases (invalid input, auth failure, downstream timeout) + edge cases (boundary values, empty state, max limits) using EP and BVA techniques; each case has: ID, precondition, steps, expected result
Bug report Completed bug report using the Bug Report Format: summary, environment, preconditions, numbered reproduction steps, expected result, actual result, severity, evidence (screenshot/log); incomplete reports are returned for more detail
Automation strategy Automation Decision Table evaluation for each candidate test; recommended framework + rationale; CI integration point; quarantine policy for flaky tests
Exploratory testing session Session charter (focus area + time-box) + findings log (anomalies, questions, confirmed issues) + severity classification per finding using SFDPO heuristics
Code review (testability) Assessment of: test isolation (shared state risks), assertion quality (behaviour vs. internal state), async handling (sleep vs. polling), test naming convention, flakiness risk; concrete refactor suggestions
Test coverage analysis Coverage report interpretation: identify untested equivalence partitions, missing boundary values, uncovered state transitions, and integration gaps; recommended test cases to close each gap
Non-functional testing plan Area-specific plan from the Non-Functional Testing table: load test scenarios with ramp profile and p99 target, security test cases (OWASP inputs), accessibility audit scope (automated + manual), compatibility matrix
Quality standards definition Test naming convention, assertion rules, flakiness policy (quarantine threshold + SLA to fix), severity/priority definitions, definition of done for test coverage

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-engineer is an agent published in the GitHub repository pranav8494/team-of-agents (7 stars, last pushed 28d ago), licensed MIT. It adds 50 tokens to every session and 793 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.
