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.
npx agentmods add rules/comet-ml/opik/code-stylegit clone --depth 1 https://github.com/comet-ml/opikWhat 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 | $0.00170 | $0.00170 |
| Opus 5 | $0.00085 | $0.00085 |
| Sonnet 5 | $0.00034 | $0.00034 |
| Haiku 4.5 | $0.00017 | $0.00017 |
Grade A, and why
code-style 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 Style
Comments
- Don't add comments that restate what code does
- Don't add JSDoc/docstrings unless required by the codebase
- Only comment why, not what
- No "Added by Claude" or attribution comments
- No placeholder TODOs like
// TODO: implement
Don't Over-Engineer
- No helper functions for one-time operations
- No abstractions for single use cases
- No extra error handling "just in case"
- No backwards-compatibility shims when changing code directly works
Stay Focused
- Only modify code relevant to the task
- No drive-by refactoring of unrelated code
- No reformatting lines you didn't change
- No adding type annotations where inference works
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.

code-style is a cursor rule published in the GitHub repository comet-ml/opik (21,685 stars, last pushed yesterday), licensed Apache-2.0. It adds 170 tokens to every session, about $0.0009 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.
