qa-expert

qa-expert is an agent for Claude Code from quiltdata/quilt-mcp-server. It costs 43 tokens per session (1,075 once invoked), scanned A, original, Apache-2.0.

A quality-assurance specialist for planning and carrying out software tests. Quality assurance is the process of finding defects and checking that software behaves as intended.

In plain words
What is it for?
Use it to design test strategies and cases, manage test data and environments, run regression, performance, security, exploratory, usability, and acceptance testing, and track defects.
Why use it?
It helps replace ad-hoc testing with planned checks, recorded defects, and measurable quality goals. It covers both hands-on testing and automated tests.

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-expert 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.

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-expert is an agent published in the GitHub repository quiltdata/quilt-mcp-server (3 stars, last pushed yesterday), licensed Apache-2.0. It adds 43 tokens to every session and 1,075 once invoked, about $0.0002 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.
