This is a well-crafted skill description that excels across all dimensions. It clearly specifies concrete actions (writing files, running tests, verification), includes natural trigger terms users would actually say, explicitly separates the 'what' from the 'when', and carves out a distinct niche around task-based implementation workflows.

Dimension	Reasoning	Score
Specificity	Lists multiple specific concrete actions: 'coding each task', 'writes source files', 'runs tests', 'verifies assertion integrity', and 'validates output against constitutional principles'. These are clear, actionable capabilities.	3 / 3
Completeness	Clearly answers both what ('Execute the implementation plan by coding each task...writes source files, runs tests, verifies assertion integrity') AND when ('Use when ready to build the feature, start coding, develop from the task list, or resume a partially completed implementation').	3 / 3
Trigger Term Quality	Includes natural keywords users would say: 'build the feature', 'start coding', 'develop from the task list', 'resume a partially completed implementation', plus references to 'tasks.md' which is a specific artifact trigger.	3 / 3
Distinctiveness Conflict Risk	Has a clear niche focused on executing from tasks.md with specific workflow elements (assertion integrity, constitutional principles). The reference to a specific file (tasks.md) and the implementation-from-plan workflow makes it distinct from general coding skills.	3 / 3

Implementation

85%

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

This is a high-quality, complex implementation skill with excellent workflow clarity and actionability. The BDD verification chain, task completion gates, and parallel execution handling are well-documented with explicit validation steps. Minor verbosity in some sections (Windows command repetition, some explanatory text) prevents a perfect conciseness score, but overall the skill is well-crafted for its complex purpose.

Suggestions

Consolidate Windows command notes into a single reference section or footnote rather than repeating inline throughout the document

Consider moving the detailed error handling table to a reference file to reduce main document length

Dimension	Reasoning	Score
Conciseness	The skill is comprehensive but includes some redundancy (e.g., Windows commands repeated multiple times, verbose error handling tables). Some sections could be tightened, though most content is necessary for the complex workflow.	2 / 3
Actionability	Provides fully executable bash/PowerShell commands throughout, specific file paths, concrete JSON parsing instructions, and copy-paste ready code blocks. Every step has explicit commands or clear decision criteria.	3 / 3
Workflow Clarity	Excellent multi-step sequencing with explicit validation gates (BDD verification chain, task completion gates, pre-implementation validation). Clear feedback loops for error recovery (§2.1-2.4, §6.5). Numbered phases with explicit checkpoints throughout.	3 / 3
Progressive Disclosure	Well-structured overview with clear one-level-deep references to supporting documents (constitution-loading.md, conversation-guide.md, parallel-execution.md, tessl-integration.md, etc.). Content appropriately split between main skill and reference files.	3 / 3
