Opik External Integrations

This skill builds Opik integrations whose code does not live in this repository. Two shapes:

• Standalone opik-* package / plugin — its own repo or package that depends on the published Opik SDK. Examples: opik-openclaw, opik-claude-code-plugin.
• Upstream contribution — Opik support added into a third-party project that already has its own logging/callback/plugin system. Examples: an Opik callback in LiteLLM, an Opik integration in Dify.

Activation gate — read this first. Use this skill only when the target lives in an external repo or external package. If the user wants an integration that ships inside sdks/python/src/opik/integrations/ or sdks/typescript/src/opik/integrations/, this is the wrong skill — use opik-integrations. When in doubt, ask the "where does it live" question (below) and route accordingly.

Two principles that make external work different

1. Follow the HOST repo's conventions, not this repo's. Structure, dependency management, lint/format, test framework, docs, and the contribution guide are dictated by the target project. Do not impose sdks/ layout, fake_backend, or Fern docs on an external repo. Read its CONTRIBUTING/AGENTS.md and mirror its closest existing integration/plugin.
2. Consume Opik through its PUBLISHED public API. Use the released opik (Python) / opik (TypeScript) SDK or the REST API — the same surface end users get. Never import this repo's internal modules (opik.decorator.*, rest_api, message-processing internals); they are not available outside this repo and are not a stable contract.

Start with the questionnaire

Collect everything up front, free-form — do not propose a target. See workflow.md Phase 0 for the full list. The essentials: which external repo/package (URL + links), integration shape (standalone package vs. upstream contribution vs. plugin), host language/stack, where the Opik code goes, how the host tests and documents, and how to run it to verify.

Once you know the target, check references.md — a curated list of known external integrations (standalone opik-* plugins incl. the cookiecutter template, and third-party host repos like LiteLLM / Dify / n8n) with their repo and Opik-docs URLs. If the target is listed or resembles one, start from its links and clone the closest sibling instead of researching blind.

The workflow

Multi-step and autonomous by default (front-load preparation, run through, self-verify, end with a report); ask for the interactive variant to approve the design first. Full playbook in workflow.md. At a glance:

0. Questionnaire + acquire the external repo (clone/checkout into the scratchpad).
1. Investigate the host — its integration/plugin conventions, dep management, test framework, docs, contribution guide. Find the closest existing integration to clone.
2. Investigate the Opik surface — pick the public API to use: @opik.track / track_* wrappers, the low-level client, or REST. Lean on the opik and instrument skills for the public API.
3. Design how Opik plugs into the host's extension point (callback hook, plugin entrypoint, middleware). Map host data → Opik trace/span fields.
4. Implement in the host checkout, mirroring its closest sibling and its style.
5. Verify via the Opik MCP — run the host with the integration active, log to the workspace the MCP reads, and read the trace/spans back. Loop until correct.
6. Test using the host's test framework and conventions.
7. Document following the host's docs conventions; optionally add/point an Opik docs page (write-docs).
8. Report — what was done, verification evidence, a per-flow supported/tested table, limitations, and how to open the upstream PR.

How this maps to the internal skill

The mechanism knowledge is shared — how a provider/framework exposes hooks, streaming, and usage is the same problem as in opik-integrations. Read that skill's python.md / typescript.md for the patterns (method patching, callback handler, OTel), but apply them against the published SDK surface and inside the host repo's structure.

Skills this one builds on (do not duplicate them)

• opik / instrument — the user-facing public API surface (the right way to consume Opik from outside).
• opik-integrations — the integration mechanism patterns (patching / callback / OTel) and field mapping.
• write-docs — only if you also add an Opik-side docs page pointing at the external integration.
