Conciseness

The workflow core (Steps 1-5, output templates, guardrail) is efficient, but Step 0 belabors skill-context rule application across multiple repetitive paragraphs ("CRITICAL: ... you MUST comply", the separate "Enforcement" paragraph restating it), and the Artifact/Config policy section is boilerplate. Mostly efficient with unnecessary explanation that could be tightened fits anchor 3; not 4 because the redundancy exceeds minor instances, not 2 because there is no padding that explains concepts Claude already knows.

Actionability

For an instruction-only skill the guidance is fully executable: a concrete three-way classification taxonomy, hard rules for evidence vs. unknowns, a numeric confidence-gate rule, and two copy-paste-ready output format templates covering both gate outcomes. Matches the top anchor; not 4 because the templates leave no gaps for the common cases.

Workflow Clarity

Steps 0-5 are clearly sequenced with an explicit validation checkpoint (the Step 4 confidence gate requiring zero open unknowns) and a feedback loop ("To reach 100: 1-3 concrete asks or commands for the user to run and paste output"). The implementation guardrail adds validate-before-act protection; this is not a destructive/batch skill so no cap applies. Fits anchor 5 rather than 4 because both the gate and the retry path are explicit.

Progressive Disclosure

The single-file skill (~110 lines) is well-sectioned with no bundle files, and the only reference (.ai-factory/skill-context/aif-grounded/SKILL.md) is one level deep and clearly signaled. Good structure with minor organization gaps — the lengthy Step 0 block could be condensed — fits anchor 4; not 5 because the file exceeds the simple-skill threshold and contains a padded section, not 3 because nothing that belongs in a separate file is inlined.

Specificity

"Forces evidence-based reasoning, explicit uncertainty, and 'insufficient information' instead of guesses" lists three concrete behaviors, matching the several-specific-actions anchor with minor gaps (confidence-gate and output-format mechanics are not mentioned). Not 5 because coverage is not comprehensive; not 3 because it goes beyond 1-2 actions.

Completeness

The description explicitly answers both what ("Reliability gate for answers. Forces evidence-based reasoning, explicit uncertainty, and 'insufficient information' instead of guesses") and when ("Use when user says 'be 100% sure', 'no hallucinations'...") with concrete trigger phrases, matching the top anchor. Not 4 because the 'when' clause is already fully explicit rather than needing more specificity.

Trigger Term Quality

Quoted phrases like "be 100% sure", "no hallucinations", "only if verified", and "grounded answer" are natural things a user would say, but common variants such as "don't guess", "cite your sources", or "no assumptions" are missing. Good coverage with a few natural terms absent fits anchor 4 rather than the comprehensive synonym coverage of 5.

Distinctiveness Conflict Risk

"Reliability gate for answers" with triggers like "no hallucinations" and "grounded answer" carves a mostly distinct epistemic-reliability niche with minor overlap risk against research/verification skills, and "when stakes are high" is somewhat broad. Fits anchor 4; not 5 due to that residual overlap, not 3 since the triggers are distinctive rather than merely somewhat specific.
