The skill is fairly dense and information-rich, but includes some redundancy (e.g., the supervisor spawn/wake/shutdown pattern is explained twice across sections, and the delegation lock table restates what could be a simpler rule). The ASCII architecture diagram and model selection guide add bulk but are mostly justified for a complex orchestration skill. Some tightening is possible.

Highly actionable with concrete spawn_agent/followup_task/close_agent call templates, exact JSON-like parameter structures, specific file paths, timeout values, and explicit tool call verdicts. The worker spawn template, supervisor lifecycle, and wave execution engine are all copy-paste ready with clear parameter placeholders.

The Wave Execution Engine provides a clear 10-step sequence with explicit validation checkpoints (skip failed deps, handle block verdicts, agent health checks, checkpoint verdicts). Error handling table covers failure modes with specific resolutions. The supervisor lifecycle (spawn -> wake -> shutdown) is clearly sequenced with feedback loops for blocked checkpoints (Override/Revise/Abort).

SKILL.md serves as a clear router/overview pointing to one-level-deep references: role files in roles/<name>/role.md, specs in specs/*.md, and templates. The Role Registry table provides direct links. Content is appropriately split between the router (this file) and detailed role/spec files, with clear navigation signals.

The description uses abstract, jargon-heavy language like 'full lifecycle team skill with clean architecture', 'universal router', and 'coordinator-only' without describing any concrete actions the skill performs. No specific capabilities are listed.

The 'what' is extremely vague — it never explains what the skill actually does. The 'when' is limited to the artificial trigger phrase 'team lifecycle v4' with no real-world usage context. Both dimensions are very weak.

The only explicit trigger is 'team lifecycle v4', which is not a natural phrase any user would say. Terms like 'universal router', 'beat model', and 'clean architecture' are internal jargon, not user-facing keywords.

The highly specific but artificial trigger 'team lifecycle v4' would unlikely conflict with other skills, but the vague domain description ('full lifecycle team skill') could overlap with any team management or project coordination skill.
