opik-optimize skillA
opik-optimize is agent-read markdown (skill) from comet-ml/opik-claude-code-plugin: Improve a prompt with the Opik Agent Optimizer — resolve the prompt, a dataset, and a metric, pick the algorithm, run a bounded optimization, check the gain on held-out data, and save the winner as a new prompt version with the optimization run link. Runs via the opik-optimizer package; reads prompts and datasets via the MCP when connected. Use for "optimize this prompt", "improve my system prompt", "make the agent answer better", "tune the prompt against my dataset", "run the prompt optimizer"..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# Optimize — Improve a Prompt Against Data **Definition of done:** an **optimized prompt** whose score on the metric **beats the baseline on data it was not tuned on**, the **optimization run link** in Opik, the cost of getting there, and the winner **saved as a new prompt version** (when the prompt lives in the library) — with the swap into code left as the next step. If the optimization can't run within a stated budget, stop at the **first** genuine blocker and return **exactly one** next step. A prompt that scores higher only on its own training items is not an improvement. Operate: **measure the baseline first, state the budget before spending it, hold data out, pick the algorithm for the failure you see, save the winner where it can be versioned — and change no application code.** The only file this skill writes is a runner outside the repo; the prompt is saved to Opik, not into the codebase. ## Inputs The entry point is `/opik-optimize <prompt-name>` (a prompt-library prompt), `/opik-optimize <path or function>` (a prompt in code), or `/opik-optimize` (find the system prompt in this repo). Infer the rest; treat these as **optional overrides**: …

How to install
mdr add comet-ml/opik-claude-code-plugin/opik-optimize@git:20260917.109a551mdr add comet-ml/opik-claude-code-plugin/opik-optimize@sha256:c5f7241f75fed1d6Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
