Names the domain (implementation planning) and one action (break down a change into a checklist), but lacks comprehensive detail about what specific actions are performed or what the output looks like.

Clearly answers both what (break down a change into implementation task checklist) and when (explicit 'Trigger:' clause with multiple specific trigger terms and conditions like 'when design exists but tasks don't').

Excellent coverage of natural trigger terms including English ('tasks', 'breakdown', 'task list') and Spanish ('desglosar', 'tareas'), plus specific command triggers ('sdd tasks', '/sdd:continue'). These are terms users would naturally say.

Somewhat specific to implementation task breakdown, but 'tasks' and 'task list' are generic terms that could overlap with general task management or project planning skills. The 'sdd' prefix helps but isn't prominent.

The skill is comprehensive but includes some redundancy, particularly in the extensive tables and repeated format examples. Some sections like the Phase Organization Guidelines could be more condensed since Claude understands organizational patterns.

Highly actionable with concrete file formats, specific markdown templates, clear estimation tags, and explicit examples of good vs bad task writing. The TDD detection chain and task format are copy-paste ready.

Excellent multi-step workflow with clear numbered steps (1-5), explicit validation through the Definition of Done section, and comprehensive error recovery table. The TDD detection chain has explicit fallback logic.

Well-structured with clear references to external files (persistence-contract.md, engram-convention.md, openspec-convention.md) that are one level deep. Content is appropriately organized into logical sections with clear headers.
