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 | $0.03478 |
| Opus 5 | $0.00000 | $0.01739 |
| Sonnet 5 | $0.00000 | $0.00696 |
| Haiku 4.5 | $0.00000 | $0.00348 |
Grade A, and why
with-tests 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 2d 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.
How it starts
The opening of the file, as written. The whole thing — 230 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Running Tests and Debugging Tests
BEFORE running or debugging tests in the codebase review the important information in this guide so you are better prepared to work with its testing strategy.
Context
• Test files: *.test.js, *.test.ts
• Config: package.json, package.jsonc, deno.json, deno.jsonc, bun.json, bun.jsonc, etc.
• Starting Tests: Deno tasks, NPM scripts, scripts/ folder, manually running a single test file if no global test runner exists, etc.
• Frameworks: Jest, Deno Test, etc.
Typical Tools Available
- Discover test commands — locate runner scripts in config:
grep_search( query: "\"test\":", include_pattern: "{package.json, package.jsonc, deno.json, deno.jsonc, bun.json, bun.jsonc}", explanation: "Find test scripts definitions" ) - Map test structure — list test files to grasp layout:
list_dir( relative_workspace_path: "test", explanation: "Examine test directory structure" ) - Inspect setup — read entry file for globals, hooks, logging:
read_file( target_file: "test/main.test.ts", should_read_entire_file: true, explanation: "Inspect test setup & config" ) - Locate patterns — search for
describe/it/test/assert/expect:codebase_search( query: "describe OR it OR test OR assert OR expect", explanation: "Locate test helpers across codebase" ) - Execute & enrich errors — run tests, capture output, grep failures:
run_terminal_cmd( command: "npm test || deno test || bun test", is_background: false, explanation: "Execute tests and capture output" ) grep_search( query: "Error|fail|assert", include_pattern: "test/**/*.{ts,js}", explanation: "Locate error patterns in tests" ) - Format logs — pretty-print, group, label for clarity
- Find Debuggers — native runtime debuggers, test inspectors, test loggers, test telemetry, test tracing tools available
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.

with-tests is a cursor rule published in the GitHub repository zackiles/cursor-config (17 stars, last pushed 1y ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 3,478 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 2026-08-30.
