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 | $0.00009 | $0.00253 |
| Opus 5 | $0.00005 | $0.00127 |
| Sonnet 5 | $0.00002 | $0.00051 |
| Haiku 4.5 | $0.00001 | $0.00025 |
Grade A, and why
setup-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 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.
What it actually says
Set up testing for Next.js 15 with framework: $ARGUMENTS (default: jest)
Steps to complete:
- Install necessary dependencies
- Create configuration files (jest.config.js, vitest.config.ts, playwright.config.ts, or cypress.config.js)
- Set up test utilities and helpers
- Create example test files for:
- Client Components
- Server Components (with limitations noted)
- Server Actions
- API routes
- E2E user flows (if Playwright/Cypress)
- Add test scripts to package.json
- Configure GitHub Actions workflow for CI
- Set up code coverage reporting
Ensure the testing setup:
- Works with Next.js 15's App Router
- Handles async components appropriately
- Includes proper mocking for Next.js modules
- Supports TypeScript
- Includes accessibility testing setup
- Has good defaults for performance
Create a comprehensive testing guide in the project documentation.
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.

setup-testing is a command published in the GitHub repository Matt-Dionis/claude-code-configs (625 stars, last pushed 1y ago), licensed MIT. It adds 9 tokens to every session and 253 once invoked, about $0.0000 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 2026-08-30.
