Hermes Agent Telemetry in Beacon | Asymptote
What is Hermes Agent?
Hermes support added prompt, observed tool, command, file, approval, session lifecycle, and subagent stop telemetry.
Collection path: Shell hooks
Authoritative date: June 5, 2026 from v0.0.40 in the Beacon CLI changelog.
How Beacon reads Hermes Agent
Beacon installs shell hooks in user-level Hermes config, preserves existing settings and non-Beacon hooks, and documents first-use hook consent options for non-interactive runs.
The result is normalized into Beacon's endpoint event schema so security teams can investigate activity by harness, repository, session, user, model, command, file, tool, MCP server, or approval context where the runtime exposes those fields.
