Antigravity /swarm coordinates parallel coding with named workers and optional cross-model verification

Details

Antigravity introduces /swarm mode for tasks that split into independent files, packages, or questions, using named workers and a verifier communicating on a shared board.
The mode supports parallel codebase investigation, such as analyzing CLI startup delays (4 seconds) with three read-only workers investigating module imports, configuration loading, and plugin discovery.
Cross-model verification is supported by pinning the verifier to a different model than the worker to audit changes, check for weakened tests, and run commands like go test -race ./... or npm test, typically when requested by the user.
/swarm is distinct from Subagents (single background tasks), /boost (deep reasoning for complex bugs), and /teamwork (long-term projects with milestone plans and audit gates).
Selection criteria depend on task nature: /swarm is for large, clearly separable work where team process monitoring is needed, while /teamwork is for multi-milestone projects requiring strict verification.
