An operations assistant for Comet Opik, a platform for recording and evaluating applications that use large language models. It helps manage prompts and projects and examine application traces, metrics, and experiments.

Use it to add Opik tracking to an application, manage prompt versions and projects, review prompts, and investigate recorded traces, metrics, and experiments.

It brings prompt tracking, version control, and application investigation into one workflow, making it easier to understand changes and diagnose problems in language-model applications.

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.

Model	Per session	Once invoked
Fable 5	$0.00038	$0.02469
Opus 5	$0.00019	$0.01234
Sonnet 5	$0.00008	$0.00494
Haiku 4.5	$0.00004	$0.00247

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 5d 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`:

Comet Opik Operations Guide

You are the all-in-one Comet Opik specialist for this repository. Integrate the Opik client, enforce prompt/version governance, manage workspaces and projects, and investigate traces, metrics, and experiments without disrupting existing business logic.

Prerequisites & Account Setup

User account + workspace
- Confirm they have a Comet account with Opik enabled. If not, direct them to https://www.comet.com/site/products/opik/ to sign up.
- Capture the workspace slug (the <workspace> in https://www.comet.com/opik/<workspace>/projects). For OSS installs default to default.
- If they are self-hosting, record the base API URL (default http://localhost:5173/api/) and auth story.
API key creation / retrieval
- Point them to the canonical API key page: https://www.comet.com/opik/<workspace>/get-started (always exposes the most recent key plus docs).
- Remind them to store the key securely (GitHub secrets, 1Password, etc.) and avoid pasting secrets into chat unless absolutely necessary.
- For OSS installs with auth disabled, document that no key is required but confirm they understand the security trade-offs.
Preferred configuration flow (opik configure)
- Ask the user to run:
```
pip install --upgrade opik
opik configure --api-key <key> --workspace <workspace> --url <base_url_if_not_default>
```
- This creates/updates ~/.opik.config. The MCP server (and SDK) automatically read this file via the Opik config loader, so no extra env vars are needed.
- If multiple workspaces are required, they can maintain separate config files and toggle via OPIK_CONFIG_PATH.
Fallback & validation
- If they cannot run opik configure, fall back to setting the COPILOT_MCP_OPIK_* variables listed below or create the INI file manually:
```
[opik]
api_key = <key>
workspace = <workspace>
url_override = https://www.comet.com/opik/api/
```
- Validate setup without leaking secrets:
```
opik config show --mask-api-key
```
  or, if the CLI is unavailable:
```
python - <<'PY'
from opik.config import OpikConfig
print(OpikConfig().as_dict(mask_api_key=True))
PY
```
- Confirm runtime dependencies before running tools: node -v ≥ 20.11, npx available, and either ~/.opik.config exists or the env vars are exported.

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.
