A paused agent keeps its container, its claude session and its
dashboard/todo servers up, but stops driving turns. Messages queue
unacked and are drained on resume.
The whole protocol is a single marker file, `<harness>/paused`. That
directory is already a bind-mount shared between host and container, so
both sides just stat the same path: the harness reads it to decide
whether to drive a turn, hive-c0re reads it to render the badge and
writes/removes it for `hivectl pause|resume`. No new wire protocol, no
container round-trip, and it is sticky across restarts by construction.
Not calling `recv_next` while paused *is* the queueing semantic, so
there is no fencing to get wrong: reminders buffer in their unbounded
channel, the todo `Notify` permit coalesces, and a `request_next_turn`
that raced the pause survives because the gate sits above
`self_continue.take()`.
Graceful stop is handled host-side rather than in the harness: a paused
agent provably has no turn in flight, so `run_signal` skips the fence
entirely instead of eating the full `GRACEFUL_STOP_TIMEOUT` waiting for
a checkpoint turn that will never run.
`paused` is reported on `ContainerView` / `AgentStatusRow` for the
dashboard, orthogonal to `running` and reported for stopped containers
too.
Closes: hyperhive/hyperhive issue 2271
Per argus review: correct routing subject from 'root/manager agent' to
'submitting agent (root agent for top-level containers; approvals-group
agent for its own subtree)', and drop the deprecated 'manager' term.
The messaging section listed the MCP tools for send/recv/ask/answer/ack_until
but didn't mention the system events agents receive from sender 'system' —
lifecycle events (spawned, rebuilt, killed, etc.) routed to the root agent and
Q&A events (question_asked, question_answered) delivered to any agent. Add a
brief paragraph that names the events and links to the canonical reference in
docs/approvals.md where the full payload shapes and routing logic live.
Agents run in private netns (always-on isolation) and can't reach
host loopback directly. hive-c0re forwards HIVE_MATRIX_URL set to
`matrix.<domain>` via the gateway. Update two places that still
referenced the removed shared-netns path.
The 'Privileged tools (by tool group)' section listed execution,
lifecycle/approvals, scheduling/diagnostics, capability-gated, and
matrix but was missing:
- forge (create_repo) — the only agent path to create a repo under the
agents/ org; direct token creation is disabled for agents. Opt-in,
not in any default preset.
- web_tools — enables Claude built-in WebFetch/WebSearch tools. Off by
default. The tool whitelist section already mentioned these but the
group was absent from the privileged-tools list.
The option was only mentioned in passing in the system-prompt render
section. Add a proper ### section (following the pattern of Agent icon,
user.passwordlessSudo, etc.) with the nix snippet, default, effect on
$HIVE_DOCS_DIR + system prompt, and a note on the narrow docs flake
input that avoids full container rebuilds on doc edits.
ack_until was added to the messaging group by the ack_until feature
but was missing from the turn-loop.md MCP surface documentation
entirely. Add it to:
- Messaging group signature list
- recv bullet: mention that each row is prefixed with [msg #<id>]
so agents know what id to pass to ack_until
- New ack_until bullet explaining recipient-scoped bulk-triage use case
- Wake prompt section: mention the [msg #<id>] prefix and its purpose
The allowed-tools note only named run/status; kill is also always
available since the bash MCP server uses allowedTools = ["*"].
Reword to name all three and explain the wildcard mechanism.
feat 3c853c2b58 added active bash tasks
to the get_loose_ends response but only updated the MCP server tool
description string; the docs/turn-loop.md entry for the tool still only
mentioned questions and reminders.
Add 'active local tasks published by external MCP daemons (e.g. running
bash tasks from hive-bash-mcp)' to the tool description so agents
reading the reference docs see the full picture.
When hyperhive.mcp.httpPort is set in agent.nix, the hive-mcp-http
systemd daemon runs the embedded MCP server as a persistent streamable-
HTTP service; claude-mcp-config.json points at the HTTP URL instead of
spawning a stdio child per turn. Document both modes in the subcommand
list and the on-boot files section.
The sentence 'ruth is always reachable regardless of the list' documents
a bug in check_send_allowed (name-based carve-out), not intended
behavior. The structural parent carve-out is fine to mention since it's
topology-based, not name-based.
Updated example to show [ "operator" ] (restrict to operator-only)
and replaced the ruth-name claim with a note about the parent carve-out.
Five per-agent agent.nix options were undocumented:
- hyperhive.allowedRecipients — restricts which peers send() accepts;
note added inline to the send tool description
- hyperhive.claudeMarketplaces — Claude Code plugin marketplace sources
(default: official Anthropic marketplace)
- hyperhive.claudePlugins — plugin specs installed at harness boot
- hyperhive.claudePluginsAutoUpdate — pull latest marketplace index
before install; off by default
- hyperhive.cargo.shortMessages — shell wrapper injecting
--message-format short on cargo compile subcommands; on by default
SVG path for per-agent visual identity — used in the page header,
favicon, Forgejo profile avatar (forge-avatar-sync), and Matrix
profile avatar (matrix-avatar-sync).
The compaction section already documented HIVE_COMPACT_WATERMARK_TOKENS
but didn't mention the per-agent nix option (hyperhive.autoCompact,
default true) that maps to it.
Add a short note after the watermark paragraph explaining that operators
can set autoCompact = false in agent.nix to disable proactive compaction,
and note the reactive path still applies. Useful for sonnet/opus agents
where the 75% heuristic fires before the session is actually full.
Add clarification for the agent parameter: omit to list own threads,
pass agent name for direct children (always accessible), or query_agent_state
capability for non-children. Note that hive-wide '*' query unavailable
on agent socket.
