The description uses vague, jargon-heavy language like 'plan-and-execute pipeline', 'pure router', 'coordinator always', and 'beat model is coordinator-only in monitor.md' without describing any concrete user-facing actions or capabilities.

The 'what' is extremely vague — it says it's a 'router' for a 'plan-and-execute pipeline' but never explains what that pipeline actually does for the user. The 'when' is limited to the trigger phrase 'team planex' with no broader context for when this skill should be selected.

The only explicit trigger is 'team planex', which is internal jargon unlikely to be naturally used by end users. Terms like 'pure router', 'coordinator', and 'beat model' are technical internals, not natural user language.

The very specific trigger phrase 'team planex' does reduce conflict risk since it's unlikely to match other skills accidentally. However, the rest of the description is so vague that without that exact trigger phrase, it would be impossible to distinguish this skill's purpose from other coordination or pipeline skills.

The skill is fairly well-structured and avoids explaining basic concepts, but includes some redundancy (e.g., the model selection guide's rationale column, the verbose spawn template, and the agent coordination section repeating patterns already shown). The delegation lock table and architecture diagram are efficient, but overall it could be tightened.

Provides concrete spawn_agent templates with exact parameter structures, specific tool call allow/block lists, explicit timeout values (1800000ms), exact file paths, and copy-paste ready code patterns. The delegation lock table is immediately actionable with clear verdicts.

The two-phase pipeline pattern is clearly sequenced (analyze → dispatch → spawn planner → wait → spawn executors → wait). Timeout cascade with explicit steps (STATUS_CHECK → FINALIZE → close_agent) provides a feedback loop for error recovery. The delegation lock acts as a validation checkpoint before every tool call. Error handling table covers failure scenarios with resolutions.

References to role files (roles/coordinator/role.md, roles/planner/role.md, roles/executor/role.md) and specs (specs/pipelines.md) are clearly signaled with links. However, no bundle files were provided to verify these exist, and the SKILL.md itself is quite long (~180 lines) with sections like the full session directory structure and agent coordination details that could potentially live in referenced files. The architecture is well-organized but borders on monolithic.
