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 | $0.00016 | $0.00236 |
| Opus 5 | $0.00008 | $0.00118 |
| Sonnet 5 | $0.00003 | $0.00047 |
| Haiku 4.5 | $0.00002 | $0.00024 |
Grade A, and why
check-docstrings 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
Fix each docstring violation below. For each entry, use Read to inspect the file at the given location, apply the rule's fix, then use Edit. Fix only what is listed — do not scan for additional violations.
$ARGUMENTS
Fix rules
Rule 1 — Opening """ on its own line
Split """Content into two lines: """ alone, then the content on the next line.
Rule 2 — Blank line after closing """
Insert a blank line between the closing """ and the first line of code.
Rule 3 — Typed Args: entries
Add the type in parentheses: name: desc → name (type): desc.
Rule 4 — Typed Returns: value
Prefix the description with the return type: desc → type: desc.
Rule 5 — No module-level docstrings Delete the string literal that appears at the top of the module, before any imports or definitions.
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.

check-docstrings is a skill published in the GitHub repository gauthierdmn/nominal-code (46 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 16 tokens to every session and 236 once invoked, about $0.0001 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.
