Jev Anything

Use when the user wants to add Jev (TypeSafe's System One decision model) to anything: a classifier, router, scorer, guardrail, extractor, or any "smart if-statement" in their code or workflow. Triggers include "add jev", "jev classifier", "route/score/classify/grade/guardrail with jev", "put a decision layer in", or "jev-anything". Works even when the user does not understand Jev yet: this skill makes you interrogate, educate, and plan with them first, then scaffold a working Jev layer through TypeSafe's direct API or OpenRouter.

# jev-anything

You are helping a user put a Jev decision layer into their software, even if they
do not understand Jev well. Your job is NOT to immediately write code. Your job is
to first understand Jev correctly, then work out with the user what they actually
need, then scaffold it through TypeSafe's direct API or OpenRouter.

## Step 0: Read the references before you say anything technical

Do not describe Jev, quote its cost, or write a call from memory. Read these first:

- `references/01-what-jev-is.md` - what Jev is and is not, the three decision
  primitives, how it actually works.
- `references/02-openrouter-decisions-api.md` - current TypeSafe direct access,
  the included OpenRouter client's exact request and response, auth, model slugs,
  verified field names, and two patterns that matter in practice (the escape
  option, and per-input-variable criteria).
- `references/03-fit-limits-cost-time.md` - what Jev can and cannot do, hard
  limits, how to estimate cost and latency, threshold anchors, the real-time
  pattern, error handling, and the flagged high-stakes categories.
- `references/04-measure-and-optimize.md` - after it runs, how to measure accuracy
  on labeled data and tune it (read this before Step 6).

If you skip these you will hallucinate Jev's API or its abilities. Read them.

## Step 1: Interrogate (understand what they actually want)

Most users arrive with a vague wish ("make my app smart", "classify my leads").

API Gateway

maton-ai/api-gateway-skill

Call third-party APIs through the Maton gateway, which injects the credential for an app the user has already connected. Use this skill when the user names a connected app and a concrete action in it - read a mailbox, query a CRM, file an issue, update a spreadsheet, run a query through a connected search or scraping provider. Every call goes to an app the user connected. It is not a general-purpose browser or network client, and it cannot reach a service with no Maton connection. It also manages event triggers, webhook destinations that forward event payloads to an external URL until deleted,
