Conciseness

The body is lean and imperative throughout — 'Extract the user's core claim from their framing. State it in one sentence stripped of premises', 'Categorise the pushback: is it new evidence or repeated opinion?' — with no explanations of concepts Claude already knows and every token earning its place. The only slight blemish is the 'When to Use' section restating the frontmatter description, which is not enough to drop it below anchor 5.

Actionability

Each step is a concrete, executable instruction with an unambiguous action (one-sentence claim extraction, evidence-for/against assessment, conclusion-first response) plus a two-branch pushback decision rule. It is not anchor 5 because a worked example — e.g. a before/after sample response demonstrating the posture — would make the guidance fully concrete for the common cases.

Workflow Clarity

The four numbered steps form a clear sequence with the assessment acting as an explicit evidence-check before concluding, and the pushback section is a genuine feedback loop with two explicit outcomes ('If new evidence --> update your position, state what changed' / 'If repeated opinion --> restate your position with the evidence'). No destructive or batch operations exist, so the validation cap does not apply.

Progressive Disclosure

The skill is under 50 lines with three well-organized sections ('When to Use', 'Process', 'Limitations') and no content that warrants external reference files; no references/, scripts/, or assets/ directories exist in the bundle. Per the rubric's simple-skill guidance, well-organized sections alone merit anchor 5.

Specificity

The description lists several specific actions — 'Eliminate sycophantic agreement patterns', 'Challenge user claims independently', 'avoid agreement bias', 'state evidence before deference' — in a named domain (sycophancy in AI responses). It falls short of anchor 5 because coverage has minor gaps: the pushback-handling behavior in the body is absent and the actions are behavioral rather than fully concretized.

Completeness

The 'what' is clear (eliminate sycophantic agreement, challenge claims, evidence before deference), but there is no 'Use when...' clause or equivalent explicit trigger guidance — 'when' is entirely missing, not just weakly implied. Per the judging guidelines this caps completeness at 3 (anchor 3), and it is not 4 because anchor 4 requires both 'what' and 'when' present.

Trigger Term Quality

Relevant keywords are present ('sycophantic agreement', 'challenge user claims', 'agreement bias', 'evidence'), but common variations and natural phrases a user would actually say are missing — e.g. 'stop agreeing with me', 'push back on my claims', 'be more critical', 'don't be a yes-man'. This matches anchor 3 ('some relevant keywords but missing common variations or synonyms') rather than anchor 4, whose keyword coverage is more complete.

Distinctiveness Conflict Risk

'Sycophantic agreement patterns' carves a clear niche unlikely to trigger for file-manipulation or tooling skills, matching anchor 4 ('mostly distinct; minor overlap risk'). It is not 5 because the niche could overlap with closely related critical-thinking/review skills, and the absence of a 'Use when' clause weakens trigger distinctiveness; it is clearly above anchor 3, whose overlap risk is with many similar skills.
