Conciseness

Lean bullet-driven sections with no over-explanation of basic concepts Claude already knows; minor repetition between the 'When to Use This Skill' list and the description keeps it just below a 5.

Actionability

Concrete behavioral directives ('State your assumptions explicitly', 'Match existing style') and concrete transform examples ('Add validation' -> 'Write tests for invalid inputs, then make them pass') give mostly executable guidance; the plan template is a skeletal placeholder rather than fully concrete, capping it at 4.

Workflow Clarity

Clear sequenced sections (Think Before Coding, Simplicity First, Surgical Changes, Goal-Driven Execution) with verify checkpoints ('verify: [check]', 'Loop until verified'); not a 5 because the verification loop is described generically rather than as an explicit validate->fix->retry feedback loop with concrete checks.

Progressive Disclosure

Well-organized into clearly signaled sections with no nested or missing references; as a self-contained behavioral-guideline skill with no need for bundle files, the structure is easy to navigate and content is appropriately placed inline.

Specificity

Lists several concrete actions ('writing, reviewing, or refactoring code', 'make surgical changes', 'surface assumptions', 'define verifiable success criteria') rather than vague language, with only minor coverage gaps; not a 5 because the actions are behavioral directives rather than a comprehensive enumerated operation set.

Completeness

Explicitly answers both 'what' ('Behavioral guidelines to reduce common LLM coding mistakes') and 'when' ('Use when writing, reviewing, or refactoring code...') with concrete trigger phrases, matching the 5-anchor example.

Trigger Term Quality

Includes natural user phrases ('writing, reviewing, or refactoring code') that a user would actually say, with good keyword coverage; not a 5 because synonyms/common variations (e.g. 'debugging', 'cleaning up code') are absent.

Distinctiveness Conflict Risk

Has a distinct niche (LLM-coding behavioral guardrails, surgical changes, verifiable success criteria) with minor overlap risk against general code-review skills; not a 5 because 'writing/reviewing/refactoring code' is broad enough to compete with related coding skills.
