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 5.1 | $0.00162 | $0.02584 |
| Opus 5.5 | $0.00065 | $0.01034 |
| Sonnet 5.5 | $0.00032 | $0.00517 |
| Haiku 4.5 | $0.00016 | $0.00258 |
Grade A, and why
opik-annotate 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 16d 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.
How it starts
The opening of the file, as written. The whole thing — 126 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Annotate — A Review Queue Annotators Can Read
Definition of done: the queue exists with the view saved, and the user knows where to check it — the write returned without a warning, and the answer carries the queue's link. A view is built from the project's real traces or threads, never from a guessed shape. If the queue or the view can't be saved, stop at the first genuine blocker and return exactly one next step.
Operate: look at real items first, cover every shape you saw, show text not JSON, keep scoring in Opik's own panel. This skill writes to Opik only and changes no application code.
Inputs
/opik-annotate <what annotators judge> ("the drafted reply", "whether the agent solved the ticket"), /opik-annotate <queue name or id> (change that queue's view), or a request to remove a view. Infer the rest; optional overrides: project (default: configured) · scope (default: trace; thread for whole conversations) · feedback definitions (default: the queue's own).
Activation — the only in-scope work
1. Resolve the project and the queue
With the Opik MCP connected: list('annotation_queue', project_name=…) shows the project's queues with their scope and item count; read('annotation_queue', id_or_name) returns one with its instructions, feedback definitions and view summary. The view's html is stated by size; read('annotation_queue', id, fields=['annotator_view.html']) returns it whole — read it before changing a view, and change only what was asked.
2. Look at real items before writing anything
- Queue with items:
list('trace', project_name=…, filters='annotation_queue_ids contains "<queue_id>"', size=20)(list('thread', …)for a thread queue), thenread('trace', id)on two or three that differ. - Empty or new queue: the project's latest traces or threads instead, and say so ("the queue has no items yet, so the view is built from the latest traces").
Note every shape input, output and metadata take: objects, arrays, or strings that hold JSON. A view that handles only the most common shape fails annotators on the rest.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

opik-annotate is a skill published in the GitHub repository comet-ml/opik-mcp (226 stars, last pushed today), licensed Apache-2.0. It adds 162 tokens to every session and 2,584 once invoked, about $0.0006 per session on Opus 5.5. 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 2026-10-29.
