BREAKING CHANGE: Tool names, schemas, and default model updated to match the hosted Browserbase MCP server. Removed screenshot, get_url, and agent tools. Removed all Smithery references and dependencies. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
- Add vitest with 11 unit tests verifying tool names, schemas, and capabilities - Add STDIO smoke test that spawns server and verifies tools/list response - Update all 3 eval configs to use new tool names (start, end, navigate, act, observe, extract) - Remove eval workflows referencing deleted tools (screenshot, url, agent) - Add pnpm test step to CI pipeline (runs before evals, needs no secrets) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

should we keep the prefix? might get confusing but if this is exact 1-1 with hosted it makes sense

I think making it line up 1-1 is the goal
The end tool now returns {"success": true} instead of
"closed successfully via Stagehand", so expectedState checks
need to use "success" instead.
