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.

What it costs to keep this loaded
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 5.1 | $0.00030 | $0.00205 |
| Opus 5 | $0.00015 | $0.00102 |
| Sonnet 5 | $0.00006 | $0.00041 |
| Haiku 4.5 | $0.00003 | $0.00020 |
Grade A, and why
write-unit-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.
What it actually says
Purpose
Create comprehensive unit tests for current code with proper imports/setup per project testing conventions.
Steps
- Test Coverage: Test all public methods/functions, cover edge cases/error conditions, test positive/negative scenarios, aim for high coverage
- Test Structure: Use project's testing framework conventions, write clear descriptive test names, follow Arrange-Act-Assert pattern, group related tests logically
- Test Cases: Happy path scenarios, edge cases/boundary conditions, error handling/exception cases, mock external dependencies appropriately
- Test Quality: Make tests independent/isolated, ensure deterministic/repeatable, keep simple/focused, add helpful assertion messages
Completion
Read completion evidence before reporting completion.
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.

write-unit-tests is a skill published in the GitHub repository blockmatic/basilic (89 stars, last pushed yesterday), licensed MIT. It adds 30 tokens to every session and 205 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 2026-09-03.
