 multi_agent = true
 ```
 
-This enables `spawn_agent`, `wait_agent`, and `close_agent` for skills like `dispatching-parallel-agents` and `subagent-driven-development`. When using subagent-driven-development, close reviewer subagents when their review returns. Keep each implementer subagent open until its task's review passes — the fix loop resumes the implementer — then close it. If your harness cannot send another message to a spawned agent, dispatch each fix round as a fresh implementer carrying the brief, the report file, and the findings.
+This enables the multi-agent tools that skills like
+`dispatching-parallel-agents` and `subagent-driven-development` use.
+Which tools you get depends on the multi-agent version your model
+preset selects (current presets run V2; older ones run V1). Trust your
+actual tool list over any table — including this one — when they
+disagree.
+
+- **Spawning:** give children a clean context with
+  `spawn_agent {fork_turns: "none"}`; the default `"all"` copies your
+  entire transcript into the child. On Codex 0.145+, role files under
+  `~/.codex/agents/` attach to isolated forks via `agent_type`.
+  Full-history forks accept `model` and `reasoning_effort` overrides
+  (only `agent_type` is refused there) — isolated forks are the SDD
+  default for context hygiene, not because overrides require them.
+- **Fix rounds:** resume the implementer with `followup_task` — it
+  delivers your message, triggers a turn, and transparently reloads a
+  child the harness evicted. Never dispatch a fresh implementer on the
+  theory that a spawned agent cannot be messaged again; on V2 it
+  always can.
+- **Lifecycle:** V2 has no `close_agent`. Finished children are
+  evicted automatically when slots are needed; leaving them unclosed
+  costs nothing. Only V1 sessions have `close_agent` — there, close
+  reviewers when their review returns, and close each implementer
+  after its task's review passes.
+- **Model names:** never copy a model name from a skill, table, or old
+  session into `spawn_agent` without checking it against your current
+  spawn allowlist — V2 accepts only V2-capable presets and hard-errors
+  on the rest.
+
+## Waiting on children
+
+`wait_agent` is an event subscription, not a poll: a long wait wakes
+the moment a child produces mailbox activity, with the same latency as
+a short one. Short-timeout polling buys nothing and costs a tool call —
+and a context rebill — per poll. In measured sessions, roughly
+two-thirds of all wait calls were short polls that timed out.
+
+- While you still have local work, do not wait at all. A completed
+  child's final answer is pushed into your mailbox and arrives with
+  your next turn.
+- When you are genuinely idle with children outstanding, wait in
+  bounded stretches: `wait_agent` with `timeout_ms` 300000-600000
+  (5-10 minutes). After each stretch — wake or timeout — post one
+  status line, run `list_agents`, and chase any child that finished
+  without reporting. Never stack polls shorter than five minutes; the
+  event subscription wakes a bounded stretch just as fast as a short
+  one.
+- Completion mail cannot wake an idle controller (it is delivered
+  without triggering a turn); covering that idle window is
+  `wait_agent`'s only job. A stretch that times out with no activity
+  is your cue to reconcile, not to shorten the next stretch.
+
+## Model routing on spawns
+
+Every `spawn_agent` you issue — including when you are yourself a
+spawned child running a fan-out — sets `model` AND `reasoning_effort`
+explicitly, per the Model Selection rules of the skill you are
+executing. Setting `model` alone is a trap: the child's effort
+silently resets to that model's default, not to yours.
+
+Ask your human partner to add a machine-level backstop to
+`~/.codex/config.toml` so any spawn that slips through still routes to
+a deliberate tier instead of silently inheriting the session's most
+expensive model:
+
+```toml
+[agents]
+default_subagent_model = "<a mid-tier model from your spawn allowlist>"
+default_subagent_reasoning_effort = "medium"
+```
