Conciseness

Lean and information-dense with no padding: it assumes Claude's competence (never explains what an eval, sandbox, or Django is) and every line carries a specific contract, path, or invariant; rationales like "so a broken seeder never masquerades as an agent regression" are skill-specific guards, not over-explanation of known concepts, so it clears the 4 anchor's "every token earns its place" bar.

Actionability

Fully executable guidance throughout — copy-paste-ready skeletons for sandboxed and one-shot suites, a real deterministic `Scorer` subclass, a `JudgedScorer` template, concrete `hogli evals` commands, exact field lists, and real import paths; the `...` placeholders are appropriate template holes, so it is not the 4 anchor's "minor gaps".

Workflow Clarity

Clear sequenced sections (Writing a suite → One-shot → Case anatomy → Seeding → Scorers → Running) capped by a numbered Verification checklist with explicit validation commands, plus a debugging feedback loop ("Start debugging with the transcript path... Then open the experiment's Agent logs directory"); the destructive/batch cap does not apply because explicit verification steps are present, so it is not capped at 3 or 4.

Progressive Disclosure

Structure and signaling are good — the body delegates field-level API detail to `references/authoring-reference.md` and provider setup to `references/running-evals.md` with clear contextual links — but those referenced files do not exist in the bundle (no `references/` directory is present), so the signaled references do not resolve and navigation is broken; this is more than the 4 anchor's "minor organization gaps" and lands at 3 where the disclosure is incomplete/unreachable rather than merely imperfect.

Specificity

Lists multiple concrete actions — "write and run evals", "adding or changing eval suites, cases, scorers, seeders, or synthesizers", "touching the harness", "running or debugging those evals" — with comprehensive coverage of the skill's scope; not the 4 anchor because it goes beyond "several specific actions" into full capability coverage.

Completeness

Explicitly answers both what ("Teaches how to write and run evals... sandboxed agent suites... and one-shot suites...") and when ("Use when adding or changing eval suites... when touching the harness... or when running or debugging those evals") with concrete trigger phrases; not 4 because the "when" is specific and multi-triggered rather than merely present.

Trigger Term Quality

Good natural-keyword coverage for the audience ("eval suites", "scorers", "seeders", "synthesizers", "hogli evals", "running or debugging those evals"); not 5 because a few natural synonyms/variations a user might say are missing for such a specialized domain.

Distinctiveness Conflict Risk

Clear niche (evals on a specific named harness) reinforced by explicit negative boundaries ("Not for ee/hogai/eval/ci/ pytest evals, and not for the LLM Analytics product's evaluation features"), giving minimal conflict risk; not 4 because the exclusions remove overlap with the closest related skills.
