Each tool targets a distinct phase of the workflow: joining a session, publishing/editing/acknowledging/reading plans, claiming/updating work, and querying status or history. Even the plan-focused tools are clearly separated by action (publish vs edit vs ack vs read), and work_claim vs work_update has no boundary ambiguity.

All tool names use snake_case with consistent resource prefixes: project_, plan_, and work_. The verb suffixes (join, publish, edit, ack, read, claim, update, status, history) are clear and follow a predictable pattern throughout.

Nine tools is well-scoped for a collaborative session and work-tracking server. Each tool earns its place, covering plan management, work claims, updates, and inspection without redundant or overlapping utilities.

The tool surface covers the core lifecycle well: join a session, publish/edit/read plans, acknowledge revisions, claim work, update work, view status, and inspect history. Minor gaps exist, such as no explicit project_leave or plan deletion, but these can be worked around using existing update/status mechanisms.
