chore: fetch Lovable AI Gateway model catalog in the daily sync - #1251
Conversation
📝 WalkthroughWalkthroughThe PR adds a Lovable AI Gateway model fetch script, a typed catalog wrapper, a generated model catalog, and integration with model generation and synchronization workflows. ChangesLovable Gateway model synchronization
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to The daily sync can fetch a changed Lovable catalog but fail to commit it when no package files change, leaving the repository's catalog stale. Merge should wait for the workflow gate to include the generated catalog path or for an owner to explicitly accept this limitation. Sequence Diagram(s)sequenceDiagram

🗄️ Data Integrity & Integration | 🟡 Minor | ⚡ Quick win
The commit gate never triggers on a Lovable-only catalog change.
The changes step at lines 36-40 sets changed=true only when packages/ differs. Nothing regenerates package code from the Lovable catalog today, so a run where only scripts/lovable-gateway.models.json changes stays at changed=false. The commit and push steps are skipped, and the fetched catalog is dropped. The committed file then stays stale until an unrelated OpenRouter or Vercel change moves packages/.
Include the staged script data in the gate.

The daily model sync now fetches the Lovable AI Gateway catalog from
https://ai.gateway.lovable.dev/v1/models, next to the OpenRouter and Vercel AI Gateway catalogs. The catalog is written toscripts/lovable-gateway.models.json, and the sync workflow commits it. No published package changes yet. A later PR can add a convert step that generatespackages/ai-lovable/src/model-meta.tsfrom this data.🎯 Changes
scripts/fetch-lovable-gateway-models.ts— fetches the catalog and writesscripts/lovable-gateway.models.json. Same pattern as the OpenRouter and Vercel fetch scripts: plain JSON output, id validation, sorted ids, 30-second timeout. The endpoint is public, so there is no API-key handling.scripts/lovable-gateway.models.ts— hand-written wrapper that re-exports the JSON typed asArray<LovableGatewayCatalogModel>, for a future convert script.package.json—generate:models:fetchnow runs the new script..github/workflows/sync-models.yml— the sync commit now includesscripts/lovable-gateway.models.json, and the PR body lists the new fetch.CONTRIBUTING.md— the model-sync section now names the Lovable AI Gateway catalog.Docs and changeset are skipped because this change is repo tooling only. It does not touch a published package.
✅ Checklist
pnpm run test:pr, or these tests do not apply to this pull request.docs/for this change, or this change is not user-facing.pnpm changeset), or this PR does not change a published package.🚀 Release Impact
Testing
Commands run
pnpm tsx scripts/fetch-lovable-gateway-models.ts— fetched 41 models and wrote the JSON file.pnpm tsx -e "import { models } from './scripts/lovable-gateway.models'"— the typed wrapper loads all 41 models.oxlintandoxfmton the two new files — clean.pnpm test:pr— passed.Manual test
pnpm tsx scripts/fetch-lovable-gateway-models.ts.scripts/lovable-gateway.models.json. Make sure that it lists the current Lovable catalog, sorted by id.pnpm generate:models:fetch. Make sure that all three fetch scripts complete.How this PR makes testing easy
The fetch script is one command with no credentials. A reviewer can run step 1 and read the output file.
Risk / rollback
Risk is low. The change writes one JSON file under
scripts/and does not touch published packages. One new failure mode: if the Lovable endpoint is down,generate:models:fetchfails, and the daily sync run fails visibly in Actions. No bad data is committed in that case. Rollback: revert this PR.Summary by CodeRabbit
