Installation

Summary

  • Compatibility router for LangWatch evaluation requests.
  • Use only when the user asks for evaluations without making it clear whether they mean pre-deployment experiments or production online evaluations.
  • Routes the request to the focused companion skill and does not implement either workflow itself.

Route an Evaluation Request

This is a compatibility skill. Do not build an experiment, monitor, or guardrail from this skill.

Classify the user's intent:

Intent Correct skill
Batch test a dataset, compare prompts or models, benchmark, create a CI quality gate experiments
Score live traces or threads, monitor production quality, create a guardrail online-evaluations

If the request remains ambiguous after inspecting context (a bare "make me an eval" that names neither a dataset nor live traffic), do not create anything yet. This choice picks what gets tested, so it is the user's to make, not a default's. Ask it as a question card and stop; the answer arrives as the next message.

In Langy, ask it with the question tool and stop; the options are the concrete alternatives, for example "A dataset, before deployment" and "Live production traffic". Elsewhere, ask the same question as one short line of prose.

A rejected field value is not this kind of choice. If a create later fails with a validation_error whose reason names the field and an expected list, correct that exact field from the list and retry once. Never turn a fixable slug into a question for the user.

Then hand off:

  1. If the correct companion skill is available, load it and follow it instead of continuing here.
  1. If experiments is missing, tell the user to install it with:

``bash npx [email protected] add langwatch/skills/experiments ``

  1. If online-evaluations is missing, tell the user to install it with:

``bash npx [email protected] add langwatch/skills/online-evaluations ``

Do not recreate the companion skill's instructions from memory. Load the focused skill so its current workflow, safety checks, and verification steps are used.
