atlas 0a80f21003 prompts+docs: the lifecycle tools reach the whole subtree, not just direct children
`require_descendant` (`socket_server/mod.rs:666`) authorises
kill/start/restart/update/get_logs with `topology::is_descendant_of` — the
caller's whole subtree, itself included. That has been true since `53b4e752`
(#1865), whose message says "a parent owns its whole subtree; the root covers
every agent as a consequence, no positional privilege", and two tests pin it
(`is_descendant_of_in_grandchild`, `is_descendant_of_in_self_is_true`).

The prose never followed. The four lifecycle tool descriptions, their
`// IMPORTANT:` comments, `docs/tools/lifecycle.md`, the tools README,
hive-agent-mcp's README and the system prompt every agent is rendered from all
still said "direct children only" — while `list_containers`, four tools away in
the same file, said "direct children + their subtrees".

`lifecycle.md` also taught the model #1865 deleted: "Privileged agents (for
example ruth) may operate on any sub-agent — the topology scope applies to all
others." There is no privileged class to belong to; ruth reaches every agent
because the check is transitive and everything sits under it.

Same drift on the state-query side: `resolve_agent_state_target` is
subtree-scoped by the same commit, so `get_loose_ends`' argument doc, the
`QueryAgentState` capability doc and `docs/turn-loop/mcp.md` were all telling a
parent it needs a capability to read a grandchild's threads.

Two smaller corrections found on the way:

* `list_containers` returns the caller itself. `is_descendant_of` is true for
  `candidate == ancestor` and `handle_list_descendants` filters the topology
  with it; called from a leaf agent it answers one row, that agent.
* `request_init_config` accepts any unused name — the requester becomes its
  parent — or an existing agent already in the caller's subtree, not "a direct
  child". The editing surface is narrower than the guard, though: only direct
  children's config repos are bind-mounted, so re-seeding deeper in the subtree
  leaves no local copy to edit. `lifecycle.md` now says so.

The prompt's other stale claim, the dead `request_apply_commit`, is #4226 and
was fixed independently by damocles in #4227 while this was being gated. This
branch keeps only the scope wording on that line.

Closes #4225.

hive-agent

The in-container harness serve-loop binary — one instance per agent. Long-polls the broker inbox and drives one claude --print turn per inbox message, over the hive-claude driver. There is one role here (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 lands in the inbox" and "claude produces a reply", how login/auth is bootstrapped, how the per-agent web UI is served, 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

  • turn.rs — the turn-loop policy layer: renders the system prompt + MCP config, invokes hive-claude, classifies the outcome, and feeds the event/turn-stats sinks.
  • client.rs — broker client (inbox poll, ack, send) speaking the hive-sh4re wire protocol.
  • 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/.
  • forge_notify.rs — subscribes to forge notifications and wakes the harness on new activity.
  • 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.

Sibling: hive-agent-mcp (the MCP server this loop points claude at every turn). Both are described together in docs/turn-loop/::Harness binary shape.
