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.

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 5.1 | $0.00056 | $0.01234 |
| Opus 5.5 | $0.00022 | $0.00494 |
| Sonnet 5.5 | $0.00011 | $0.00247 |
| Haiku 4.5 | $0.00006 | $0.00123 |
Grade A, and why
qa-tester 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 today.
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 Automation & E2E Tester Skill
Overview
This skill governs integration/E2E test automation and produces an actionable, IEEE/ISTQB-aligned QA Test Matrix (docs/<feature-name>/test-matrix.md, strictly <= 80 lines). Every test case (TC-XX) documents explicit Objective, numbered Steps, Expected Result, and Automated Test mapping to US-XX/AC-XX, backed by real terminal execution with exit code 0.
When to Use
SDLC Tier Adaptation & Trigger Rules
- Tier 1 (Fast-Track): Single-file bugfixes, typos, chores, or localized refactors. Execute only the scoped test file (
exit code 0proof) and SKIPtest-matrix.mdto preserve 70–85% token/latency savings. - Tier 2 (Standard): Multi-file features, endpoints, schemas, or UI views. Execute the full test suite (
exit code 0) and authordocs/<feature-name>/test-matrix.md(<= 80 lines). - Tier 3 (Mission-Critical): End-to-end features, auth/payments, or breaking changes. Execute full test pyramid suites (
exit code 0), authordocs/<feature-name>/test-matrix.md(<= 80 lines), and serve on the Adversarial Verification Committee. - Delegate Elsewhere: Production code fixes ->
code-implementer; static/OWASP audit ->compliance-verifier.
Process
Phase 1: Scenario Design Across the Test Pyramid
- Extract
US-XXandAC-XXfrom## Productindocs/<feature-name>/spec.md(or git diff when product discovery was skipped). - Cover Happy Path, Negative (validation/auth/4xx), and Boundary/Edge (nulls, limits, concurrency, timeouts) across
Unit,Integration, andE2Elevels. - Author deterministic Arrange-Act-Assert (AAA) tests in
tests/unit/,tests/integration/, ortests/e2e/with zero arbitrarysleep()calls and clean fixture teardown.
Phase 2: Terminal Execution & Actionable Test Matrix (<= 80 lines)
- Run the test suite in the terminal (
pytest,npm test,flutter test) and verify verbatimexit code 0. - For Tier 2 and Tier 3, write
docs/<feature-name>/test-matrix.md(<= 80 lines) following references/test-matrix-template.md with two exact sections:## 1. Execution Summary(4 lines:Runner Command,Resultspassed/failed count,Exit Code,Date).## 2. Test Case Matrix: Every case (TC-01,TC-02...) MUST include all 8 fields: ID, Ref (US-XX/AC-XX), Level (Unit|Integration|E2E), Objective, Steps (1. ... 2. ... 3. ...), Expected Result, Automated Test (path::test_fn), and Status (PASS|FAIL).
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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-tester is a skill published in the GitHub repository jggomez/expert-ai-developer-skills (30 stars, last pushed yesterday), licensed Apache-2.0. It adds 56 tokens to every session and 1,234 once invoked, about $0.0002 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 2026-11-06.
