swarm-logs covers every host-tier unit this tool could reach, so the
second, capability-gated path into host journald earns nothing and is
removed outright rather than disabled behind a flag.
Removed end to end: the MCP tool definition + handler, the
GetHostJournal/HostJournal wire variants, hive-c0re's
dispatch_host_journal handler, the ReadHostJournal capability, and the
harness-side capability->--allowedTools gate. get_host_journal was the
only capability that mapped to an MCP tool, so allowed_capability_tools
could only ever return an empty vec; it goes too rather than linger as a
function that provably does nothing.
capabilities::has_cap/caps_for stay: #4624 gave ManageRootAgent's
bind-mount enforcement (hive-c0re/src/lifecycle/host_config.rs) a
second caller of has_cap, so they're no longer callerless once this
lands on top of it.
hive-sh4re's journal module (JournalPriority) had no consumer outside
this tool and is deleted.
An existing capabilities.json still naming read_host_journal does not
error: capabilities::prune_unknown drops unrecognised names with a
warn!, and an agent left with no capabilities has its entry removed. No
migration step is needed.
Untouched: hive-c0re/src/dashboard/journal.rs's
read_host_journal_response, which matches the name but is the private
helper behind the operator-only GET /api/journal-host dashboard route
and carries no capability check.
Both agent-facing tools go away end to end, with no replacement. This is
an intentional capability removal: agents can no longer enumerate their
own subtree, and can no longer queue a meta-flake input bump.
The system prompt and docs/tools/lifecycle.md land in this same commit
on purpose. A tool named in the prompt but absent from the server makes
agents confidently call something that doesn't exist, and the failure
then surfaces far from its cause.
Removed:
- MCP registrations and bodies (hive-agent-mcp), plus the now-unused
UpdateMetaInputsArgs.
- Wire variants Request::ListDescendants,
Request::RequestUpdateMetaInputs and Response::Containers, plus
ContainerInfo, whose only consumer was that response.
- hive-c0re's handle_list_descendants (its whole module) and
handle_request_update_meta_inputs, the two dispatch arms, and the
require_group(agent, "approvals", ...) gate on the meta-inputs verb.
- The stream_enrich emoji entry and argument formatter.
- docs/tools/lifecycle.md (both tools it documented are gone), its two
referrers, the tool-group tables and the agent-hierarchy prose.
Tool groups are kept, deliberately. ToolGroup::Lifecycle listed exactly
one tool and now lists none — it is vestigial, but the variant stays so
existing meta/capabilities.json grants still parse; retiring it is a
separate decision. ToolGroup::Approvals also listed exactly one tool,
but the group is NOT dead: check_can_cancel_approval still gates
cancel_loose_end's approval-cancel arm on it server-side.
ApprovalKind::UpdateMetaInputs stays too. Nothing in production code
produces it any more, but pre-existing approval rows may still carry it,
and the operator's own path to a meta update is unaffected — the
dashboard's POST /api/meta-update inserts the meta_update job directly,
bypassing approvals entirely.
The two format_ack tests in hive-agent-mcp that named
request_update_meta_inputs were only using it as a label string while
exercising the generic OkWarn/Ok renderer, so they are retargeted to a
surviving tool rather than deleted.
Note hive-c0re's priv_client::list_containers is a different thing (the
host-side privileged container listing behind hive-priv) and is
untouched.
Closes#4591
get_loose_ends now always returns the caller's own loose ends, for every
caller including the manager (ruth) — there is no separate manager
surface, ruth is a normal agent with different default capabilities.
- AgentGetLooseEndsArgs removed; get_loose_ends takes no args.
- Wire Request::GetLooseEnds collapses from an Option<String> target to
a unit variant.
- hive-c0re's handle_get_loose_ends drops the "*" hive-wide branch and
the subtree/capability resolver (resolve_agent_state_target); both
are gone since there is no longer a target to resolve.
- loose_ends::hive_wide and Capability::QueryAgentState removed as
dead code — their only callers were the two functions above.
- is_descendant_of is untouched (still used by lifecycle_handlers.rs
and schedules.rs independently of this change).
- Docs updated: docs/turn-loop/mcp.md, docs/web-ui/dashboard.md,
docs/process/conventions.md (Loose-ends wire shape + capabilities
table), plus the doc comments in hive-core-agent-sock, mcp_config.rs
and capabilities.rs that described the old shape.

Container lifecycle from inside an agent goes away: an agent no longer
starts, stops, restarts or rebuilds a container in its subtree, and no
longer reads another container's journal. Those are operator actions —
the dashboard and hivectl keep their own paths to the same job-queue
and hive-priv plumbing, which is why none of that machinery is removed
here, only the five MCP verbs and what they alone reached.
What went with them: the `Request` variants and `Response::Logs` on the
agent socket, the five tool definitions and their arg structs, the four
lifecycle handlers plus `handle_get_logs`, and `require_descendant` —
the topology guard those five were the only remaining callers of.
`ToolGroup::Diagnostics` goes too: `get_logs` was its only tool, so it
would otherwise be a grantable group that grants nothing. `lifecycle`
stays, now carrying `list_containers` alone.
An agent that gets a `needs_update` or `container_crash` helper event
has no remedy of its own left, so the system prompt and the docs now
send it to the operator instead of to a tool that no longer exists.
Refs #4480
swarm-controller's `InitAgentConfigRepo` node already covers config-repo
creation, so this deletes a duplicate rather than a capability; old
`init_config` rows are skipped by `collect_lenient` with no migration, by
operator decision.
Refs #4398
`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.
The gateway's nginx + dnsmasq no longer run in their own nspawn container.
`nix/host-modules/hive-gateway/default.nix` loses the
`containers.hive-gateway` wrapper and everything that existed only to punch
holes in it: `privateNetwork = false`, `CAP_NET_ADMIN`, five bind mounts,
its own `stateVersion`, `networking.firewall.enable = false`,
`networking.resolvconf.enable = false`, and the `hive-gateway-resolv`
path+service pair. 465 -> 303 lines.
The container never bought isolation here. It shared the host netns by
necessity — nginx binds the host's :80/:443, dnsmasq answers on the bridge —
so each of those settings was undoing a boundary the gateway could not
afford in the first place.
Four things made it more than a deletion, none of them visible in the nix
diff:
- The self-signed cert service also imports the hive CA leaf, so removing it
with the container would have left nginx naming a missing cert file, which
it refuses to load at all.
- The nginx reload is a hive-priv verb. It still needs root, but no longer
for the reason its doc gave, and `--machine=` was both transport and
scope — so the unit name is now hard-coded in the helper as the
containment.
- The lifecycle verb named a container that stops existing.
- `journalctl -M hive-gateway` had no machine to enter.
Per the operator's ruling, the operator verb keeps working and agents lose
it. `InfraContainer` answered three questions that used to share an answer;
it now splits into `name()` (identity), `target()` (Container vs HostUnit),
`service_unit()` (the systemd unit), and `agent_restartable()`, which the
MCP restart path checks before the capability so the refusal cannot read as
"ask for infra_admin". `SIBLING_CONTAINERS` drops the gateway — it gates the
requests that name a container as a string — while `FromStr` still accepts
it, because that answers what a name is, not who may act on it. The
dashboard's gateway journal reads host journald filtered to `nginx.service`.
Prose was corrected where it only named a location, and re-argued where the
container was doing security work: a `0666` per-agent socket was safe
because only the gateway container had the directory bind-mounted. There is
no mount now, so the directory permissions are the whole of the access
control — the constraint holds, its mechanism doesn't.
Gate: nix fmt / clippy --all-targets -D warnings / cargo test all clean (710
tests); hivectl-cli.md regenerated from the clap tree. The nix eval was run
in both TLS shapes at this commit: every delta in the rendered
virtualHosts is one of the three intended path moves, dnsmasq settings are
byte-identical, and the absence probe flips true -> false with bindMounts
emptied.
Closes the #3110 split — lib.rs is now just the crate doc comment and
the pub mod list.
journal.rs's new doc comment fixes a pre-existing bug: the old
JournalPriority doc text in lib.rs was actually half Capability's doc
(a leftover from an earlier reorder that moved the code but not the
comment above it).
Seven places described an authoring flow that does not exist: the
manager editing and committing a child's config in the bind-mounted
config dir. mara, on the snapshot issue: "the pr workflow is the main
one, anything else is legacy … the config dir in agent container is
read only copy to see own config … changes need to go through local
clone and via forge".
Two of the seven are the request_init_config MCP tool description and
its args struct, which are rendered into the system prompt of every
agent holding the approvals tool group. A wrong tool description is not
a stale comment; it is an instruction the whole hive reads as fact,
which is why the claim kept being repeated back.
The init tool creates the repo and seeds it. Nothing else. Tailoring
the seeded template is not a separate mechanism - it is the ordinary
config-change flow, a PR reviewed like any other.
Prose only; the code already implements the PR flow (an approval's
commit_ref is a PR number). Where a doc justified the parent's
read-write mount on the child's config dir with the authoring model,
the justification is removed rather than replaced: that mount is a
defect tracked on its own issue, and it should not read as intentional
while it waits.
Adds a real MCP-side path for the workaround #2639 documented: dial the
in-container HIVE_AGENT_SOCKET directly from cancel_loose_end (kind:"todo")
instead of shelling out via a tracked bash task (nc -U ...), which is what
was spawning a fresh completion todo on every clear and cascading forever.
hive-agent-mcp/src/mcp/render.rs: renamed local_todos's socket-dial guts
into a shared dial_agent_socket(req) helper, added mark_local_todo_done(id)
on top of it (MarkTodoDone request already existed server-side, unused
until now). mod.rs wires kind:"todo" into cancel_loose_end ahead of the
question/reminder/approval parse. args.rs + render.rs + docs/tools/bash.md
text updated to point at the new path instead of the old raw nc invocation.
