…agent dispatch Mode B (Subagent Fan-Out) docs told the coordinator to 'Use SendMessage to resume subagents', but plain subagents (dispatched by subagent_type with no name) are not addressable. Following that guidance nudges an agent to attach a name, which converts the target into a teammate — and a coordinator already running as a teammate then trips 'Teammates cannot spawn other teammates — the team roster is flat'. - coordinator.md: replace the misleading Mode B Communication line with the correct one-shot-subagent semantics + explicit flat-roster warning - build.md: drop SendMessage from the SUBAGENT MODE tool list - SKILL.md: tag Communication Channels 1-2 as Mode A / teammate-only Prose-only; no dispatch call changed. Version 4.43.0 -> 4.46.0.

Summary
Mode B (Subagent Fan-Out) docs told the coordinator to "Use SendMessage to resume subagents" — but plain subagents (dispatched by `subagent_type` with no `name`) are not addressable. Following that guidance nudges an agent to attach a `name`, which converts the target into a teammate — and a coordinator already running as a teammate then trips "Teammates cannot spawn other teammates — the team roster is flat".
Prose-only clarification across the three dispatch-doc sources. No actual dispatch call changed (they were already correct —
subagent_typeonly, noname).Changes
agents/coordinator.md— Mode B "Communication:" line rewritten: subagents are one-shot (collect return value; dispatch fresh to continue), with an explicit flat-roster warning. Removed "Use SendMessage to resume subagents".commands/build.md— droppedSendMessagefrom the SUBAGENT MODE tool list ("plain subagents only").skills/dev-squad/SKILL.md— tagged Communication Channels 1–2 (SendMessage) as Mode A / teammate-only + added a caveat note.4.43.0→4.46.0(both manifests).Versioning
Sits above the in-testing PRs #30 (4.44.0) and #31 (4.45.0) so this release does not force those to renumber. Both remain open/unmerged.
