atlas f3860f3497 hive-claude 0.1.4: the idle watchdog stops claude with SIGINT 
hive-claude 0.1.4 (hive-claude #28) sends the idle watchdog's signal as
SIGINT to claude's process group instead of SIGKILL. It then waits for
claude to exit, with no SIGKILL fallback. claude stops the commands its
Bash tool started when it shuts down on SIGINT, and a SIGKILL left them
running. This is the last SIGKILL of a claude process from #4999.

hive-agent's `idle_timeout` -> `Error::IdleTimeout` -> `TurnError::ApiStall`
path is unchanged. The difference is that the error now arrives only
once claude has exited. A claude that ignores the SIGINT keeps the turn
open until it is killed by hand or the unit stops.

The Cargo.lock change is only hive-claude's version and checksum. A plain
`cargo update -p hive-claude --precise 0.1.4` also moved seven crates'
Windows-only `windows-sys` edges from 0.61.2 to 0.52.0, unrelated to this
bump. The minimal lock passes `--locked`.

The turn-loop and web-UI docs, and hive-agent's watchdog docs and stall
note, now say SIGINT instead of "killed". That includes the ACP spots
that the previous commit's `Drop` change made stale.

hive-agent

The in-container harness serve-loop binary — one instance per agent. Long-polls the broker inbox and drives one turn per inbox message through hive-runtime, on the agent's runtime (claude --print by default, or an ACP agent). It has one role (agent); the Surface trait + AgentSurface zero-sized type tag keep the turn loop generic and testable for future roles without a parallel copy of the loop.

When to use it

You don't call into this crate from elsewhere — it's the top-level binary systemd starts per agent container. Look here when you need to understand or change: what happens between a message landing in the inbox and the agent's reply, how the harness bootstraps login/auth, how it serves the per-agent web UI, or how turn/event stats get recorded. Architecture detail lives in docs/turn-loop/; this README is just the map of the module tree.

Shape

  • main.rs — the serve loop and the Surface trait; broker calls (inbox poll, ack, send) go through hive-sock-client with hive-core-agent-sock wire types.
  • turn.rs — the turn-loop policy layer: renders the system prompt + MCP config, runs the turn through hive-runtime, classifies the outcome, and feeds the event/turn-stats sinks.
  • login.rs / login_session.rs — first-run and session-resume auth flow for the claude CLI.
  • mcp_config.rs — renders the per-turn --mcp-config / --allowedTools blob from tool groups + capabilities.
  • todos.rs / reminders.rs / todo_server.rs — the harness-local loose-ends v2 stores (sqlite-backed) and the in-agent socket server extra MCP daemons + hive-agent-mcp dial into for todo/reminder ops.
  • vacuum.rs — periodic sqlite vacuum sweep for the harness-local stores.
  • events.rs / turn_stats.rs / stats.rs — append-only event sink and per-turn telemetry recording (context usage, cost, tool favorites) under harness/.
  • prompt.rs — system-prompt renderer (persona + tool docs + environment facts).
  • web_ui/ — the per-agent dashboard (terminal pane, status, schedules) served over the built-in hive-agent web port.
  • paths.rs — canonical path resolution for state/harness dirs and the harness-local sqlite files.

Siblings: hive-agent-mcp (the MCP server this loop points the agent at every turn) and hive-runtime (the library a turn runs through). docs/turn-loop/::Harness binary shape covers all three together.
