npx skills add langwatch/skills --skill evaluations
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.
npx skills add langwatch/skills --skill evaluations
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:
If the correct companion skill is available, load it and follow it instead of continuing here.
If experiments is missing, tell the user to install it with:
If online-evaluations is missing, tell the user to install it with:
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.
