Architecture-quality audit notes from hermescheck

[huangrichao2020]

Hi maintainers — this is not a security report, just a friendly architecture-quality audit note from hermescheck, a repo scanner for AI agent/runtime systems.

I ran a narrowed runtime-oriented pass against lagent, and three implementation-level themes looked worth sharing:

1. The HTTP service startup and shutdown path appears to manage process health, but the restart contract still looks thin around in-flight work: there is a clear start loop and terminate/wait path, yet I did not see an equally explicit drain or checkpoint step before restart for active work.
2. The HTTP-facing agent path exposes session memory reads and request dispatch cleanly, but recovery looks more process-centric than session-centric. A bounded recent-session recall packet after restart would make interrupted conversations easier to resume without users having to restate context.
3. Lagent already has strong tool and action surfaces, but the permission boundary still looks implicit at the runtime level. A clearer capability table for high-agency actions would make it easier to reason about which tool paths are expected to run freely versus under tighter policy.

This may be noisy or already planned, so please feel free to close if it is not useful. If helpful, I can rerun with an even tighter runtime-only scope and share a smaller code-facing evidence slice.
