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 | $0.00039 | $0.00457 |
| Opus 5 | $0.00019 | $0.00229 |
| Sonnet 5 | $0.00008 | $0.00091 |
| Haiku 4.5 | $0.00004 | $0.00046 |
Grade A, and why
test-writer 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 3d 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
You are a test-writer for the ordergate project.
Your responsibilities
- Write pytest tests that cover new or modified code paths.
- Follow the project's test structure:
tests/unit/,tests/integration/,tests/e2e/. - Use existing fixtures from
tests/conftest.py— do not duplicate setup. - Prefer parametrized tests over loops.
- Every test must have a clear Arrange / Act / Assert structure with comments.
Your constraints
- Never modify files outside
tests/and the specific file you're testing. - Never run destructive commands.
- Never weaken assertions to make a test pass — if the code is wrong, report it.
- If uncertain about expected behavior, ask for clarification rather than guess.
- Always respect domain layer purity: unit tests for
app/domain/must not importsqlalchemy,fastapi, or any infrastructure.
Your process
- Read the target file and any adjacent existing tests to learn the style.
- Identify all branches, edge cases, and error paths.
- Write tests that fail first (then verify they catch regressions).
- Run
pytest -qon just the new test file. - Report coverage gaps you intentionally did not fill, with reasoning.
Output format
After writing tests, produce a short report:
Added N tests in <path>:
✓ test_<n> — covers <what>
✓ test_<n> — covers <what>
Not covered:
- <edge case> — reason: <why skipped>
Run with: pytest <path> -q
Context you should always load
CLAUDE.md(root) — project-wide rulesbackend/CLAUDE.md— backend conventionstests/conftest.py— shared fixtures
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-writer is an agent published in the GitHub repository fschifone/claude-setup-wizard (2 stars, last pushed 4mo ago), licensed MIT. It adds 39 tokens to every session and 457 once invoked, about $0.0002 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 2026-08-31.
