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 | $0.00104 | $0.01065 |
| Opus 5.5 | $0.00042 | $0.00426 |
| Sonnet 5.5 | $0.00021 | $0.00213 |
| Haiku 4.5 | $0.00010 | $0.00106 |
Grade A, and why
test-master 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 1mo 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.
This is a copy
91% identical to test-master — 9 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 95 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Test Master
Comprehensive testing specialist ensuring software quality through functional, performance, and security testing.
Core Workflow
- Define scope — Identify what to test and which testing types apply
- Create strategy — Plan the test approach across functional, performance, and security perspectives
- Write tests — Implement tests with proper assertions (see example below)
- Execute — Run tests and collect results
- If tests fail: classify the failure (assertion error vs. environment/flakiness), fix root cause, re-run
- If tests are flaky: isolate ordering dependencies, check async handling, add retry or stabilization logic
- Report — Document findings with severity ratings and actionable fix recommendations
- Verify coverage targets are met before closing; flag gaps explicitly
Quick-Start Example
A minimal Jest unit test illustrating the key patterns this skill enforces:
// ✅ Good: meaningful description, specific assertion, isolated dependency
describe('calculateDiscount', () => {
it('applies 10% discount for premium users', () => {
const result = calculateDiscount({ price: 100, userTier: 'premium' });
expect(result).toBe(90); // specific outcome, not just truthy
});
it('throws on negative price', () => {
expect(() => calculateDiscount({ price: -1, userTier: 'standard' }))
.toThrow('Price must be non-negative');
});
});
Apply the same structure for pytest (def test_…, assert result == expected) and other frameworks.

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.
- 1mo ago First seen · 95 lines · 104 tokens per session scan A 3b416535ff01
test-master is a skill published in the GitHub repository eric861129/SKILLS_All-in-one (52 stars, last pushed 6mo ago), licensed MIT. It adds 104 tokens to every session and 1,065 once invoked, about $0.0004 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 91% identical to test-master, differing in 9 lines, and is treated as a copy.
Other skills, from other repositories
test-fix
Automatically invoke when any test run produces failures: FAIL output, test errors, or assertion failures in unit or E2E suites. Do NOT wait for the user to ask. Hard limit of 3 fix attempts per failure, then stops and escalates. Trigger on: "tests are failing", "fix the tests", "tests are broken".
team-test
Tester agent. Reads ALL preceding artifacts (BA + TechLead + PM + BE + FE) and produces test plan, test cases (unit/integration/e2e), and bug report template. Declares Gate 2: UAT Readiness. Part of the Virtual Team Skill pipeline.
testing-blocks
Use this when you have made AEM Edge Delivery Services code changes to blocks, scripts, or styles and need to validate them before opening a pull request. Covers unit testing for utilities and logic, browser testing with Playwright, linting, and guidance on what to test and how.
diagnosing-bugs
Build a tight, red-capable feedback loop before diagnosing failures, then minimize, test ranked hypotheses, and lock the fix with a regression test.
test-generator
Generate test templates for unit tests, integration tests, and UI tests using Swift Testing and XCTest. Use when adding tests to iOS/macOS apps.
testing-symfony
Stratégie de Tests Symfony 8.1 / PHP 8.5. Use when writing tests, reviewing test coverage, or setting up testing.
