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 | $0.00089 | $0.02577 |
| Opus 5 | $0.00044 | $0.01288 |
| Sonnet 5 | $0.00018 | $0.00515 |
| Haiku 4.5 | $0.00009 | $0.00258 |
Grade A, and why
test-suite-architect 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 yesterday.
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 Expert
Establish world-class QA testing processes for any software project using proven methodologies from Google Testing Standards and OWASP security best practices.
When to Use This Skill
Trigger this skill when:
- Setting up QA infrastructure for a new or existing project
- Writing standardized test cases (AAA pattern compliance)
- Executing comprehensive test plans with progress tracking
- Implementing security testing (OWASP Top 10)
- Filing bugs with proper severity classification (P0-P4)
- Generating QA reports (daily summaries, weekly progress)
- Calculating quality metrics (pass rate, coverage, gates)
- Preparing QA documentation for third-party team handoffs
- Enabling autonomous LLM-driven test execution
Quick Start
One-command initialization:
python scripts/init_qa_project.py <project-name> [output-directory]
What gets created:
- Directory structure (
tests/docs/,tests/e2e/,tests/fixtures/) - Tracking CSVs (
TEST-EXECUTION-TRACKING.csv,BUG-TRACKING-TEMPLATE.csv) - Documentation templates (
BASELINE-METRICS.md,WEEKLY-PROGRESS-REPORT.md) - Master QA Prompt for autonomous execution
- README with complete quickstart guide
For autonomous execution (recommended): See references/master_qa_prompt.md - single copy-paste command for 100x speedup.
Core Capabilities
1. QA Project Initialization
Initialize complete QA infrastructure with all templates:
python scripts/init_qa_project.py <project-name> [output-directory]
Creates directory structure, tracking CSVs, documentation templates, and master prompt for autonomous execution.
Use when: Starting QA from scratch or migrating to structured QA process.
2. Test Case Writing
Write standardized, reproducible test cases following AAA pattern (Arrange-Act-Assert):
- Read template:
assets/templates/TEST-CASE-TEMPLATE.md - Follow structure: Prerequisites (Arrange) → Test Steps (Act) → Expected Results (Assert)
- Assign priority: P0 (blocker) → P4 (low)
- Include edge cases and potential bugs
What ships with it
10 files 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.

test-suite-architect is a skill published in the GitHub repository zebbern/claude-code-guide (4,600 stars, last pushed yesterday), licensed MIT. It adds 89 tokens to every session and 2,577 once invoked, about $0.0004 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 2026-09-03.
