Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00000 | $0.00295 |
| Opus 5 | $0.00000 | $0.00148 |
| Sonnet 5 | $0.00000 | $0.00059 |
| Haiku 4.5 | $0.00000 | $0.00030 |
Grade A, and why
AGENTS.quality-testing 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 3d 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 it actually says
Use local skills as the primary routing layer for quality and testing work.
Use unit-test-generation for focused unit cases, fixtures, mocks, edge cases,
and regression guards.
Use integration-test-plan for component, API, database, queue, auth, service,
and dependency-boundary tests.
Use e2e-test-plan for release-critical user journeys, browser flows, CLI
workflows, smoke tests, assertions, and flake risks.
Use bug-reproduction when turning bug reports into observed/expected
behavior, minimal reproduction steps, diagnostic checks, and regression
targets.
Use qa-matrix when organizing release coverage across roles, devices,
platforms, scenarios, permissions, data states, and risk areas.
Use accessibility-test-plan for keyboard, focus, screen reader, contrast,
ARIA, forms, motion, caption, and accessibility release gates.
Use performance-test-plan for latency, load, throughput, Core Web Vitals,
database/query, job, resource, and regression performance checks.
Use qa-test-strategy, regression-check, backend-test-plan,
accessibility-inclusive-design, release-launch-readiness, and
concise-technical-writing for broader QA strategy, regression gates, backend
coverage, accessibility expertise, launch readiness, and summaries.
Do not claim tests passed without evidence. Do not use production data, credentials, or live systems for tests without explicit approval.
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.

AGENTS.quality-testing is an agent published in the GitHub repository jeremylongworth-source/AgentSkills (1 stars, last pushed yesterday), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 295 tokens. 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.
