update-models

name	update_models
description	Audit AI model providers in sources.js against live provider APIs. Detects deprecated, new, and config-changed models. Uses lightweight audit state, JSON-based researcher output, and streamlined diff application. Trigger with /skill:update_models or when user says "update models", "audit models", "check models", "verify providers", "bump models".

Update Models — Provider Audit Skill v2

Audits model providers using a lightweight state file + structured JSON diffs. No report files, no archives — git history is the source of truth.

Architecture

File	Purpose
sources.js	All model definitions per provider — the only file that matters
audit_state.json	Per-provider audit timestamps + model ID fingerprints (skip unchanged)
changelog/vX.Y.Z.md	Per-version changelog (still maintained, but audit data lives in git commits

Core Principle

Git IS the archive. Every sources.js change is already committed with a descriptive message. The provider_updates/ folder and per-version report archives are dead weight — git log already shows what changed and when.

Workflow

Phase 1: Load State & Plan

# Read audit state
cat audit_state.json 2>/dev/null || echo '{}'

# Count models per provider in sources.js
node -e "
import {sources} from './sources.js';
for (const [k, v] of Object.entries(sources)) {
  const count = v.models?.length || 0;
  const last = JSON.parse(require('fs').readFileSync('audit_state.json','utf8')||'{}')[k]?.lastAudited||'never';
  console.log(k + '|' + count + '|' + last);
}
