Release v0.3.1

Release v0.3.1

• eval generate now works on ADK 2.x projects that use built-in tools such as VertexAiSearchTool. Raised the google-cloud-aiplatform floor to 1.156.0, which carries the SDK fix.
  • #27
• Skills installed via agents-cli setup are now visible to Antigravity. Global skills are mirrored into the Antigravity skill directories.
  • #26
• update now surfaces errors clearly instead of failing silently.
• Agent deploys tolerate a corrupt or malformed deployment_metadata.json instead of crashing.
• Deployment timestamps are now timezone-aware.
• A malformed AGENTS_CLI_EXPERIMENTS value no longer crashes the CLI.
• agents-cli install now runs with --locked, so a drifted uv.lock fails fast instead of silently resolving new dependency versions.
