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 | $0.00000 | $0.00372 |
| Opus 5 | $0.00000 | $0.00186 |
| Sonnet 5 | $0.00000 | $0.00074 |
| Haiku 4.5 | $0.00000 | $0.00037 |
Grade A, and why
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 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.
What it actually says
Testing Standards
Coverage Targets
- Line coverage: ≥ 80%
- Branch coverage: ≥ 75% on critical paths
- Function coverage: ≥ 90%
Test Structure (AAA Pattern)
it('should return error when input is empty', () => {
// Arrange
const input = ''
// Act
const result = validateInput(input)
// Assert
expect(result.ok).toBe(false)
expect(result.error).toBe('Input cannot be empty')
})
Naming
- Describe behavior, not implementation:
'should return 404 when user not found' - Not:
'test getUserById with invalid id'
Test Data
- Use factories/builders, not hardcoded values
- Seed random data with
fakerfor variety - Reset state between tests
Mocking Rules
- Mock external dependencies (HTTP, DB, filesystem)
- Don't mock your own code (that's testing the mock)
- Verify mock calls when behavior matters, not just return values
Flaky Test Prevention
- No
setTimeoutorsleepin tests - Use
waitForwith explicit conditions - Deterministic test order (each test is independent)
- No shared mutable state between tests
Edge Cases Checklist
- Empty/null input
- Maximum/minimum boundary values
- Unicode and special characters
- Concurrent operations
- Network timeout/error
- Permission denied
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.

testing is a cursor rule published in the GitHub repository dasomel/oh-my-cursor (2 stars, last pushed 5mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 372 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.
