AgentXchain v2.37.0

2.37.0 adds Google Gemini as the third governed api_proxy provider, hardens Gemini-specific failure handling, fixes the Homebrew mirror PR automation path, and ships a first-class examples docs library.

Google Gemini is now a governed api_proxy provider​

AgentXchain now supports three api_proxy providers out of the box: OpenAI, Anthropic, and Google Gemini.

The Google connector uses the Gemini generateContent endpoint with URL query-param API-key auth and responseMimeType: "application/json". Config validation now accepts provider: "google" for api_proxy blocks.

The three-provider governed proof demonstrates a real multi-provider workflow: OpenAI PM → Google architect → Anthropic QA, with phase transitions, semantic gate evaluation, and mock-backed governed E2E.

Gemini-specific failure handling​

Gemini responses that are blocked or truncated now surface with provider-specific messages instead of collapsing into generic extraction noise:

  • promptFeedback.blockReason — surfaces the exact block reason when Gemini refuses a prompt
  • Non-STOP finishReason — surfaces when Gemini returns no parts, empty text, or MAX_TOKENS truncation

This ensures operators get actionable feedback when a Gemini-backed role fails, not opaque parse errors.

Homebrew mirror PR automation​

The publish workflow now creates the Homebrew mirror PR itself instead of leaving an orphan branch for manual cleanup:

  • Added pull-requests: write to the publish workflow permissions
  • PR creation now fails closed — if gh pr create fails after branch push, the workflow fails
  • Manual cherry-pick and manual PR creation are no longer accepted fallback patterns

Examples docs library​

Every shipped example now has its own dedicated docs page under /docs/examples/:

  • 14 example pages covering consumer SaaS, mobile, B2B, developer tools, open source libraries, governed proofs, MCP agents, and remote conformance
  • Examples is a first-class category in the docs sidebar
  • Hub page at /docs/examples with navigation to all detail pages
  • llms.txt and sitemap.xml updated for discoverability

  • 2915 tests / 609 suites / 0 failures
