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 | $0.00124 | $0.00124 |
| Opus 5 | $0.00062 | $0.00062 |
| Sonnet 5 | $0.00025 | $0.00025 |
| Haiku 4.5 | $0.00012 | $0.00012 |
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
- Unit test public methods and edge cases. Cover the public surface of each unit, including boundary conditions, empty/zero inputs, and error paths — not just the happy path.
- Use property-based testing where applicable. When behavior holds over a range of inputs (round-trips, invariants, ordering, idempotence), assert the property over generated inputs rather than enumerating examples by hand.
- Prefer hand-rolled fakes/in-memory implementations over mocking 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.

testing is a cursor rule published in the GitHub repository Jacoby6000/Smithplates (2 stars, last pushed 21d ago), licensed MIT. It adds 124 tokens to every session, about $0.0006 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.
