Quality

Content

48%Weight 40%Scale 1-5

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

The body presents a clear TDD workflow with verification checkpoints, but is padded with generic software-engineering principles Claude already knows and relies on stub/non-executable code with broken path syntax. It is monolithic with no progressive disclosure via reference files.

Suggestions

Remove the generic-principle sections (Implementation Guidelines DRY/YAGNI/KISS/SOLID, Performance Optimization, Documentation Standards) that Claude already knows; retain only SPARC-specific guidance.

Replace stub comments ('// Implementation', '// Arrange, Act, Assert') with executable code and fix the '$' path separators to '/' (e.g. 'tests/unit/auth.test.js') so examples run as written.

Move large reference-style blocks (Code Patterns, Error Handling Patterns) into separate reference files linked from the overview to reduce the monolithic inline content.

Dimension	Reasoning	Score
Conciseness	The ~226-line body pads several sections with concepts Claude already knows (DRY/YAGNI/KISS/SOLID, 'choose efficient data structures', 'proper indexing', 'pagination') and stub code, matching 'noticeably verbose; several unnecessary padded sections'.	2 / 5
Actionability	Some concrete guidance exists (retry-with-backoff, file structure), but most code is pseudocode with undefined variables (authTestSuite, userModel) and broken '$' path separators instead of '/', matching 'pseudocode instead of executable code; missing key details'.	3 / 5
Workflow Clarity	The Red/Green/Refactor phases are clearly sequenced with verification checkpoints (Bash('npm test') after each phase, plus lint in Refactor); only an explicit 'if failing, fix and retry' feedback loop is missing.	4 / 5
Progressive Disclosure	The file has clear section headers but is a monolithic 226-line document with no bundle files or external references; code patterns, optimization, and error-handling blocks that belong in separate files are all inlined.	3 / 5

Description

3%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

The description is a meta invocation stub rather than a capability statement: it says how to invoke the skill but not what it does or when to use it. It fails on specificity, trigger terms, and completeness.

Suggestions

Replace the invocation stub with a concrete capability statement, e.g. "Transforms specifications into working code using TDD: writes failing tests, implements minimal code, then refactors for quality".

Add an explicit 'Use when...' trigger clause with natural user phrases such as 'implementing a feature from a spec', 'writing code test-first', or 'refactoring for quality'.

Drop the 'invoke with $...' syntax from the description; it conveys no capability or trigger information.

Dimension	Reasoning	Score
Specificity	The description only states "Agent skill for implementer-sparc-coder - invoke with $agent-implementer-sparc-coder"; it names a domain but lists zero concrete actions, matching the 'entirely vague; no concrete actions' anchor.	1 / 5
Completeness	Neither 'what' (just 'agent skill for X') nor 'when' (only invoke syntax, no 'Use when...' clause) is meaningfully present; both are extremely vague, matching the lowest anchor.	1 / 5
Trigger Term Quality	It contains only the technical identifier "implementer-sparc-coder" and invocation syntax "$agent-implementer-sparc-coder"; no natural keywords a user would say, matching 'only technical jargon'.	1 / 5
Distinctiveness Conflict Risk	The named identifier narrows it slightly, but the template 'Agent skill for X - invoke with $X' is generic and identical across all such agent skills, giving high overlap risk.	2 / 5
	Total	5 / 20 Passed
