Names the domain (response letters) and a general action (transforming defensive/harsh language), but doesn't list multiple specific concrete actions like what the transformation produces or specific techniques used.

Describes what it does (polishes response letters by transforming defensive/harsh language) but has no explicit 'Use when...' clause or equivalent trigger guidance, which per the rubric caps completeness at 2, and the 'what' itself is also somewhat thin, bringing it to 1.

Includes some relevant terms like 'response letters', 'defensive', 'harsh language', and 'polishes', but misses common variations users might say such as 'tone', 'soften', 'rewrite', 'professional', 'diplomatic', or 'complaint response'.

The focus on 'response letters' and 'defensive or harsh language' provides some specificity, but could overlap with general tone-editing, writing improvement, or email polishing skills.

Extremely verbose and bloated. Contains massive amounts of boilerplate (Risk Assessment, Security Checklist, Lifecycle Status, Evaluation Criteria, Output Requirements, Response Template, Input Validation) that are generic filler not specific to tone polishing. The skill explains concepts Claude already knows and repeats itself across sections (e.g., 'Overview' restates the intro, 'Workflow' is generic project management boilerplate). Easily 3x longer than needed.

The transformation table and before/after examples are genuinely useful and concrete. The Python API example and CLI usage are specific. However, much of the 'actionable' content is generic boilerplate (e.g., the workflow section is not specific to tone polishing at all), and it's unclear whether scripts/main.py actually exists or is just aspirational. The core value—the tone patterns and expression library—is actionable but buried in noise.

The 'Workflow' section is entirely generic project management boilerplate ('Confirm the user objective, required inputs...') with no specificity to tone polishing. There is no clear sequence for how to actually polish a response—no steps like 'identify defensive phrases → classify tone → apply transformations → verify position preserved.' The Quality Checklist is useful but disconnected from any workflow. Missing validation/feedback loops for the actual polishing process.

References to external files (references/polite_expressions.json, references/tone_patterns.md, references/examples/) are present and one-level deep. However, the SKILL.md itself is monolithic with enormous inline content that should be split out (the full expression library, the transformation tables, the security checklist, etc.). Section ordering is poor—'Overview' appears after 'Implementation Details' and 'Quick Check', and there are circular references ('See ## Prerequisites above' when Prerequisites appears below).
