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 | $0.00263 |
| Opus 5 | $0.00005 | $0.00131 |
| Sonnet 5 | $0.00002 | $0.00053 |
| Haiku 4.5 | $0.00001 | $0.00026 |
Grade A, and why
1-clean-code 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
Code Quality:
- Maintain strict typing.
- Disallow untyped values and magic numbers.
- Use explicit enums for possible values.
- Avoid double negatives and ensure conditions are self-documenting.
- Use long, readable variable names reflecting domain concepts.
- Write the simplest code possible
- Eliminate duplication (DRY).
Length Limits:
- Max 20 lines per function : extract until you drop.
- Max 3 parameters per function.
- Max 300 lines per file.
- Max 10 sub-files per folder.
Responsibilities:
- One responsibility per file.
- Organize code by domain concepts (e.g., Communications, Player, Action).
Functions:
- No flag parameters; split into multiple functions if needed.
- Follow command-query separation.
- Use verbs for service methods that perform actions.
Errors:
- Fail fast and throw errors early.
- Use custom domain errors and translate errors to user language.
- Log errors in English with error codes.
Code Organization:
- Follow Ports & Adapters pattern with clear separation between entities, repositories, services, enums, events, listeners, and value objects.
- Favor composition over inheritance.
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.

1-clean-code is a cursor rule published in the GitHub repository cmnemoi/cursor-rules (2 stars, last pushed 1y ago), licensed MIT. It adds 9 tokens to every session and 263 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 2026-08-31.
