Conciseness

The core content is dense, actionable templates rather than prose padding, but there is real duplication: grader types, pass@k guidance and thresholds, and the eval artifact layout each appear twice (main body and the 'Product Evals (v1.8)' appendix), and the 'Philosophy' section states concepts that are largely restated by 'When to Activate'. Mostly efficient but needs tightening — anchor 3; it avoids anchor 2 because it never explains concepts Claude already knows.

Actionability

Grader examples are copy-paste ready ('grep -q "export function handleAuth" src/auth.ts && echo "PASS" || "FAIL"', 'npm test -- --testPathPattern="auth"'), and eval/report templates are concrete. However, the central eval loop contains placeholders ('[Run each capability eval, record PASS/FAIL]') and the '/eval define|check|report' commands are referenced with no implementation or mechanism — minor gaps, anchor 4 rather than 5.

Workflow Clarity

The Define → Implement → Evaluate → Report workflow is clearly sequenced with a template and checklist for each phase, and eval definitions naturally serve as validation checkpoints. It falls short of anchor 5 because there is no explicit failure-recovery feedback loop (what to do when an eval fails mid-implementation is left implicit).

Progressive Disclosure

As a single-file skill with no bundle files, it relies on well-organized sections, which are logical and easy to navigate (activation triggers, eval types, graders, metrics, workflow, storage, examples). The main gap is that the 'Product Evals (v1.8)' appendix duplicates main-body content instead of being merged or split into a reference file — minor organization gaps, anchor 4.

Specificity

The description names the domain ("Formal evaluation framework for Claude Code sessions implementing eval-driven development (EDD) principles") but states no concrete actions — it never mentions defining evals, measuring pass@k, or generating reports, which the body actually covers. It matches anchor 2 ('names the domain but actions are minimal or generic') rather than 3 because no specific capability is listed.

Completeness

The 'what' is present (a formal evaluation framework implementing EDD principles) but the 'when' is entirely absent — there is no 'Use when...' clause or equivalent trigger guidance, which caps completeness at 3 per the judging guidelines. It does not reach 4 because nothing implies activation conditions.

Trigger Term Quality

Terms like "evaluation framework", "eval-driven development", and "EDD" are relevant, but the description misses natural variations users would say such as "evals", "pass@k", "regression testing", or "benchmarking agent performance". Some relevant keywords exist, but common synonyms are missing — anchor 3.

Distinctiveness Conflict Risk

The EDD/eval-harness niche is fairly distinct from unrelated skills, with only minor overlap risk against generic testing or code-review skills (e.g., a user asking to 'evaluate this code'). It does not reach 5 because the absence of explicit triggers leaves moderate risk of firing on generic evaluation requests.
