fix(scripts): skip OpenRouter aliases and stop copying tool templates - #1109
Merged
Conversation
The model sync generator treated ~routing aliases as models and stamped every new native-provider model with another model's tool list. Skip aliases, share one identifier sanitiser, and infer only features that OpenRouter reports.

📝 WalkthroughWalkthroughModel synchronization now shares model-ID validation, excludes routing aliases, and generates provider support metadata from model capabilities. Maintainer tests include model-sync tests, and documentation describes synchronization and CI validation steps. ChangesModel synchronization
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔵 Low · up to The model-sync fixes are mergeable, but the maintainer documentation still describes routing aliases unclearly, which could cause confusion during future sync runs; clarify that wording as a follow-up.

Correct the routing-alias description.
Replace “Those ids move under you” with a direct statement such as “Those IDs are unstable and cannot become JavaScript identifiers.” The current sentence is unclear.

OpenRouter catalog still emits ~anthropic/claude-haiku-latest (const name maps ~ to _). Native openai/anthropic/gemini/grok sync still skips those ids.

Problem
The daily model sync (
pnpm generate:models, PR #1048) was generating bad metadata:~anthropic/claude-haiku-latest) became invalid or fake constants.computer_use,local_shell,google_search,x_search,web_fetch,priority_tier).The scheduled job itself is green. The generator was still writing the wrong facts.
Fix
scripts/model-sync/ids.tsandscripts/model-sync/provider-supports.ts.~aliases.toModelConstNamethrows if a caller forgets to filter.supported_parameters.toolsis[]until a human curates them.pnpm test:maintainer.1048
Do not rebase
automated/sync-models. Merge this intomain, then re-run Sync Model Metadata. That rebuilds #1048 from the fixed generator.The sync workflow still pushes with
GITHUB_TOKEN, so Test / E2E will not start on that push. After the rebuild, run the PR checks from the Actions tab or push an empty commit. A PAT for auto-CI is a separate decision (new secret).Test plan
