comet-opik

comet-opik is an agent for Claude Code from jiamaozheng/awesome-claude-code. It costs 38 tokens per session (2,482 once invoked), scanned A, original, no licence file.

An agent for Comet Opik, a tool for recording and examining how applications use large language models. It works with prompts, projects, traces, and performance measurements through Opik's MCP server.

In plain words
What is it for?
Use it to instrument LLM applications, organise projects and prompts, audit prompt changes, and investigate traces and metrics.
Why use it?
It brings prompt management, prompt checks, and investigation of recorded model activity into one workflow. This can reduce the need to inspect model behaviour across separate tools.

Token cost

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.

Security

Grade A, and why

comet-opik scanned grade A with 2 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 1mo 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.

Unrestricted tool accesslowExcessive agency

A wildcard tool grant or "run any command" leaves no least-privilege boundary at all.

tools: ['*']

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

- For scripted diagnostics, prefer CLI over raw HTTP. When CLI is unavailable (minimal containers/CI), replicate the requests with `curl`:

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.
