atlas d6c8cd5a6f subagent: hand a subagent its parent's built-in tools, and no others 
`build_config` spawned a subagent with `--dangerously-skip-permissions`
and no `--tools` at all, so it got claude's entire built-in set —
`SendMessage` and `ListAgents` (message peers, or the operator, as its
parent), `Task*` including `TaskStop`, which takes an *agent* id and so
reaches clean outside the run, `Cron*`, `RemoteTrigger` and
`EnterWorktree`/`ExitWorktree`. None of that is part of "do this bounded
task in this directory", and none of it is something the parent agent
itself can do: the harness has always passed `--tools`.

Pass the same one. The value comes from
`hive_sh4re::permissions::builtin_tools_arg()` — literally the function
the harness resolves its own session with — so the subagent's set is the
parent's set, `HIVE_TOOL_GROUPS` and all. That inheritance is the
requirement, not an implementation detail: a hardcoded subagent list
would hand `WebFetch`/`WebSearch` to the subagent of an agent without the
`web_tools` group, which is a privilege escalation, and would drift from
the parent's list the first time anyone added a tool to either.

`--tools` is the real gate: it holds under
`--dangerously-skip-permissions`, unlike `--allowedTools`, which only
auto-approves prompts. It does not filter MCP tools, so the
`goal_reached`/`need_help` signal surface is deliberately unnamed in it
and survives on `--strict-mcp-config` alone.

`build_config`'s doc comment claimed `strict_mcp_config` was *the* safety
property and that a subagent got "nothing implicit and nothing more".
That was false for built-ins, and is what hid this gap for as long as it
did; it now says which flag covers which half and that neither
substitutes for the other.

An empty `--tools` value parses as *unset* and grants more than omitting
the flag, so an empty resolution can only be a bug — `build_config`
asserts against it and a test pins the non-emptiness alongside the
subset-of-parent property.

hyperhive docs

Depth reference for hyperhive — the substrate, not the pitch (that's the top-level README / website). Every page here stands alone; pick the one matching your task rather than reading top to bottom. For the autogenerated NixOS options reference (every services.hyperhive.* / hyperhive.* option, host and agent), see the options site instead — this tree is prose, that one's generated straight from the module declarations.

Getting started

  • Bringing a fresh hive online? → getting-started/setup.md (first-run hivectl bootstrap).
  • What does the dashboard look like, and how do I use it? → web-ui/ — the operator-facing starting point; its own sub-pages (shape, dashboard, agent, css-vars, terminal-rendering) go deeper into implementation.
  • What tools does an agent (or the operator) have available? → tools/ — hivectl (yours) plus every agent's MCP tool surface (bash, forge, lifecycle, matrix, scheduling).

Agent lifecycle

Trust boundary & security

Accounts & integrations

  • How do per-agent forge accounts work? What does forge_notify poll, and how does it format wake messages? → integrations/forge.md (the hive's own Forgejo); tools/forge.md for the hive-forge CLI verbs agents actually call.
  • How does the matrix-tuwunel container work? Multiple accounts per agent? → integrations/matrix.md (the homeserver); tools/matrix.md for the MCP tool surface and hyperhive.matrixAccounts.
  • How do I give an agent a GitHub account (gh + git push)? how's the PAT injected? → integrations/github.md (operator content up top; the gh/git-push + notification-poller mechanics are in a collapsed "Implementation" section at the bottom).
  • What's /knowledge? How does the hive-wide knowledge repo sync, and how do I contribute a document? → integrations/knowledge.md.
  • What does hivectl do? Provisioning, gateway users, container shells? → tools/hivectl.md (the curated guide); tools/hivectl-cli.md for the exhaustive, autogenerated flag reference.

Networking & swarms

  • What nginx vhosts does the gateway serve? How does matrix discovery work? → networking/gateway.md.
  • How does DNS resolution work in agent containers? What's the bridge network for? → networking/network.md.
  • How do I connect two hives into a swarm? → swarm/ (peer hives, TLS trust).
  • Where do agent snapshots go? How does the swarm's btrfs receive endpoint authenticate a pushing hive? → networking/snapshot-store.md.

Scheduler, CI, observability

  • what's the job queue, as a general idea (not hive-c0re specifics)? → scheduler/jobq.md — operator-facing, no implementation detail.
  • How does the rebuild queue work? What are the concrete step kinds, queue sources, scheduler internals? → scheduler/coordinator.md.
  • How does the CI runner work? What's the autoregistration flow? → scheduler/ci.md.
  • How do I export Claude Code metrics (tokens, cost, tool calls) to Prometheus/Grafana? → scheduler/observability.md.

Crate reference

  • What does a specific Rust crate do, on its own terms? → crates/ — every workspace crate's own README.md, one level up from source; the crate itself is still the source of truth, this is just a walkable mirror.
