mara on #5170: "dont split caps and perms. its all perms. / dont include
the now empty tool groups / nothing set -> default / also add perms to
agent creation screen".
- hive-sh4re: one `Permission` enum (messaging, meta, inbox, execution,
web_tools, manage_root_agent) replaces `ToolGroup` and `Capability`;
`lifecycle`/`forge` are gone. `Permission::default_for` is the default
for an agent the swarm sets nothing for.
- The record is `{ "permissions": [...] }`. Missing key, unset field or
no successful read yet = default; `[]` = none; a failed read after a
good one keeps the last value.
- hive-agent reads its own key every 10s and builds each turn's --tools,
--allowedTools and MCP config (rewritten before every turn) from it;
the subagent daemon reads it on each start/continue. Agents get a
read-only grant on their own key.
- hive-c0re restarts an agent only when its manage_root_agent changes.
The import now merges meta/capabilities.json and meta/tool-groups.json
into one list per agent and deletes both; the "import pending, don't
read" decision is `ImportOutcome::read_allowed`, table-tested.
- swarm-controller: `GET /api/permissions` (names + default) and an
optional `permissions` on `POST /api/agents`, stored before the job is
queued. swarm-ui's create-agent form gets a permissions field.
- Deleted: HIVE_TOOL_GROUPS and its forward to the subagent daemon,
tool_groups.rs, ruth's tool-group seed, the permissions rebuild job
(PermPayload/WritePermFile/perm_change), the dashboard permissions tab
and its stale-entries panel.
Part of #5170.
An agent's capabilities move from the hive's meta repo
(`meta/capabilities.json`, injected as `HIVE_CAPABILITIES`) into the
`capabilities` field of its key in a new `agent-permissions` KV bucket,
which swarm-controller alone writes.
- swarm-queue-client: `agent_permissions` (bucket, key, `AgentPermissions`,
direct-get read, the import subject and its wire types).
- swarm-controller: creates the bucket at start; `GET|PUT|DELETE
/api/agents/{name}/permissions` (deny_unknown_fields and unknown
capability ⇒ 422, duplicate ⇒ 400, agent must be declared by a hive);
answers each hive's one-shot import, writing a key only where there is
none and only for agents that hive's wanted state declares.
- swarmctl: `agent permissions get|set|clear`.
- swarm-nats-auth: a hive reads every key of the bucket and sends its
import on its own subject; the controller subscribes to the imports and
may answer them (`responses`).
- hive-c0re: reads each of its agents' keys every 30s into
/var/lib/hyperhive/swarm-agent-permissions.json and restarts an agent,
gracefully, when its capabilities change. Unset is the compiled-in
default (ruth: manage_root_agent; everyone else: none). A failed read
keeps the stored value. On first boot it seeds that file from
meta/capabilities.json, sends the grants to the controller, and deletes
the file once the controller answers.
Deleted: the capabilities.json reader/writer, `HIVE_CAPABILITIES` in the
rendered meta flake, ruth's capability seed, the capabilities half of the
permissions rebuild job (`PermPayload::Capabilities`/`Combined`), the
dashboard's capabilities table and `capabilities_changed` event, and the
now-unused `Capability::description`.
