Conciseness

The ~15-line body has no padding: every line instructs (definition of a suggestion, one-line format, card placement), and it trusts the reader's competence ('Keep the reasoning until the user asks'). It never explains concepts Claude already knows, matching the 'every token earns its place' anchor.

Actionability

The card block is a copy-paste-ready template and the format rule is exact ('the problem, then `→` what you would do'), but the JSON holds only a `…` placeholder with no filled-in example, and 'the band keeps those' is unexplained jargon leaving minor gaps.

Workflow Clarity

This is a simple single-action skill and the action is unambiguous: hold the suggestion, end the reply with it as a card ('never in its text'), and carry on with the task. No destructive or batch operations are involved, so the validation cap does not apply.

Progressive Disclosure

The skill is under 50 lines with no need for external references (no references/, scripts/, or assets/ exist), and the short paragraph structure is fully adequate for content of this size, matching the simple-skill exception.

Specificity

It enumerates concrete, comprehensive categories of what gets surfaced ('a decision it would make differently, effort it saw wasted, a better route to the goal, a fact the user lacks, friction in the tools, permissions, setup or docs') in third person, with no vague padding or over-claims. Not 4: there are no coverage gaps to point to.

Completeness

It explicitly answers both questions: the 'what' is the enumerated list of surfaced items, and the 'when' is concrete ('Use when you hold one of these and have not said it'). Not 4: the when-clause is already explicit and specific, not something that 'could be more explicit'.

Trigger Term Quality

Relevant keywords exist ('change', 'friction', 'tools, permissions, setup or docs') but the natural phrases a user or agent would echo are missing — 'feedback', 'complaint', 'suggestions', 'what would you do differently'. Fits 'some relevant keywords but missing common variations'; not 4 because coverage is partial rather than good-with-a-few-missing.

Distinctiveness Conflict Risk

A clear niche (agent-held unspoken suggestions, emitted as a card at reply end) with a distinct trigger, but it can overlap with general feedback/review skills that also collect improvement suggestions. Mostly distinct with minor overlap risk.
