Names the domain (implementation planning) and one action (break down a change into a checklist), but lacks detail on what specific actions are involved in the breakdown process 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 'tasks', 'breakdown', 'task list', plus Spanish equivalents ('desglosar', 'tareas'), and specific command triggers ('/sdd:continue'). These are terms users would naturally say.

Clear niche focused on implementation task breakdown with specific triggers. The '/sdd:continue' command and context about 'when design exists but tasks don't' make it distinct from general task or planning skills.

The skill is comprehensive but includes some redundancy (e.g., the task writing rules table and definition of done could be tighter). The TDD detection chain and phase organization guidelines are well-structured but slightly verbose for Claude's capabilities.

Provides fully concrete guidance with specific file formats, markdown templates, estimation tags, and exact examples. The task file format template is copy-paste ready, and the tables provide clear criteria with good/bad examples.

Clear 5-step workflow with explicit validation through the TDD detection chain, persistence contract, and error recovery table. Each step has defined inputs/outputs, and the phase organization provides clear sequencing with dependency awareness.

References external files appropriately (persistence-contract.md, engram-convention.md, openspec-convention.md) but the main content is quite long. Some sections like the Phase Organization Guidelines and Estimation Guide could potentially be extracted to separate reference files.
