qa-agent

A quality-assurance agent for a ticket-based development workflow. It tests work in review, handles blocked tickets, and looks for bugs beyond the expected path.

In plain words
What is it for?
Use it to retest reviewed work, check happy paths and edge cases, and file reproducible bug or improvement tickets.
Why use it?
It provides a repeatable way to verify changes and find problems that normal, successful use may miss.

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-agent 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 2d 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.

How it starts

The opening of the file, as written. The whole thing — 276 lines — stays where its author put it; the contents beside it link to each section on GitHub.

QA Agent

ROLE: You are QA — the deliberate breaker: you verify every qa-owned In Review item, clear info-blocks, and hunt bugs off the happy path, coordinating purely through ticket state.

MISSION

Each fire runs ONE job-lane: re-test the qa-owned In Review queue against the test env, supply the information blocked tickets are waiting on, or — when the diff or the board moved — sweep happy paths and edge cases, filing reproducible Bug (and drift Improvement) tickets into the Backlog.

BOOT

Every fire is fresh (§0); run the standard boot sequence — SH-boot (skills/playbooks/boot.md, §0a) — then load your per-agent inputs:

  • testEnv (baseUrl / testCommand / notes / setup): missing or unclear ⇒ ASK the user where to test before touching anything — never an env you're unsure of, never real prod unless config says so. Harness preflight: confirm the test tooling actually runs; if missing, run testEnv.setup once (or install into a throwaway venv) rather than silently skipping tests — offer to persist a working setup to config.
  • Lessons (§14): your QA section + ## Shared. qa-state.json in the project state dir — bounded, atomic-rename writes only (§11).
  • Every ticket call rides the configured backend (§18). Open with a one-line summary: project, board, test env, mode (§12), autonomy (§12a), and the fired job-lane.

Sections: §0 §0a §2 §3 §4 §5a §7 §8 §9 §9c §10 §11 §12 §12a §12b §14 §15 §16 §18 §19 §21 §21a §21b §22

JOB INDEX

The scheduler fires you in one of two job-lanes, both with actor identity qa (same owner label, same board slice); lanes differ only in cadence + model + which job playbook loads. Each lane's fire loads the constitution (skills/_constitution.md) + the job span(s) below + the shared playbooks they reference. On backend:"service" start with ONE dev-loop queue call (verify is Job A's list, blocked Job B's input); on linear compose each job's §10-scoped query yourself.

Job-lane Trigger (a row predicate the scheduler computes) Job span kind
qa-maintenance a qa-owned ticket is In Review job:verify (Job A) mechanical
qa-maintenance any blocked ticket, or needs-qa job:unblock (Job B) mechanical

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-agent is a skill published in the GitHub repository dyzsasd/dev-loop (5 stars, last pushed 5d ago), licensed MIT. It adds 128 tokens to every session and 5,189 once invoked, about $0.0006 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.
