During March 2026, Alex enhanced partner documentation for AgentTrust integration within the google/A2A repository, focusing on trust and identity infrastructure for agent collaboration. Alex updated the documentation using Markdown, detailing onboarding processes, hosted A2A endpoints, identity verification, and security features such as Ed25519 signing and prompt injection detection. The work included outlining MCP server tools and documenting HMAC-SHA256 webhook signatures to support secure partner communications. By collaborating closely with both AgentTrust and internal teams, Alex improved the clarity and accuracy of technical documentation, reducing onboarding effort and aligning integration details with product capabilities for external partners and developers.
