Names the domain (roadmap-driven development) and describes a pipeline (plan -> execute -> verify), but the actual concrete actions are vague — 'discusses roadmap', 'dispatches phased execution pipeline' are abstract process descriptions rather than specific capabilities like 'creates task breakdowns' or 'generates implementation plans'.

It partially answers 'what' (coordinator discusses roadmap, dispatches phased execution) and has a trigger clause ('Triggers on "team roadmap-dev"'), but the trigger is an artificial command rather than a natural 'Use when...' clause describing user scenarios. The 'when' is technically present but not useful for natural skill selection.

The only explicit trigger is the artificial phrase 'team roadmap-dev', which is not something a user would naturally say. Terms like 'coordinator', 'dispatches', and '--role arg' are internal jargon, not natural user language. Missing natural terms like 'plan project', 'development workflow', 'break down tasks', etc.

The artificial trigger 'team roadmap-dev' would prevent false positives, but the description's mention of 'roadmap-driven development workflow' and 'plan -> execute -> verify' could overlap with other project planning or development workflow skills. The specificity of the artificial trigger helps but the underlying domain description is somewhat generic.

The content is mostly efficient and avoids explaining basic concepts, but includes some sections that could be tightened—the Model Selection Guide rationale column is somewhat redundant, and the architecture ASCII diagram, while helpful, is verbose. The Delegation Lock table is thorough but borderline over-specified for things Claude could infer.

Provides concrete spawn_agent templates with exact parameters, specific tool call allowlists/blocklists, exact file paths, timeout values (1800000ms), and precise session directory structures. The worker spawn template is copy-paste ready and the error handling table gives specific resolutions.

The multi-phase pipeline is clearly sequenced (PLAN -> EXEC -> VERIFY with gap closure loop, max 3 iterations). Validation checkpoints are explicit: agent health checks via list_agents, verification phase with gap closure feedback loops, timeout escalation protocol (STATUS_CHECK -> FINALIZE -> mark timed_out -> close). The Delegation Lock acts as a pre-execution validation gate.

SKILL.md serves as a clear router/overview with well-signaled one-level-deep references to role files (roles/coordinator/role.md, roles/planner/role.md, etc.) and specs (specs/pipelines.md). The Role Registry table provides a clean navigation index. Content is appropriately split between the overview here and detailed role instructions in referenced files.
