Conciseness

The body is dense and mostly free of explanations of known concepts, but the SDK handoff proof ladder is written out in full twice (Workflow step 7 and the Validation section), and the "First-Principles Gate" section is abstract boilerplate padding. Mostly efficient with clear tightening opportunities — anchor 3, not 2, since most lines carry real guidance.

Actionability

Guidance is copy-paste ready for an instruction-only skill: a concrete YAML output template, a fully worked example with expected output, executable validation commands ("./bin/ask skills audit … --level strict --json --robot"), and specific thresholds ("Treat oss-local misses as 70-75 discovery-band repair inputs"). Matches the anchor for fully executable, common-case-covering guidance.

Workflow Clarity

The seven-step workflow is clearly sequenced with explicit validation checkpoints ("stops at the first failed gate"), a fail-fast rule, and error-recovery loops via the Failure Mode section and the blocked_by mechanism. Destructive actions (merge, fold, retire, publish) are explicitly gated behind approval, satisfying the destructive-operation validation requirement.

Progressive Disclosure

Structure is good: the four referenced files (taxonomy.md, discovery-interview.md, evidence-routing.md, harness-evidence-mapping.md) all exist in the bundle, are clearly signaled, and are one level deep. Minor gaps: the long proof-ladder detail is inlined rather than split to a reference, and the References section lists external "Infrastructure/references/…" paths that are not part of the bundle. Anchor 4 rather than 5's cleanly split, easily navigable structure.

Specificity

The description lists multiple concrete actions — "Analyzes bounded skill evidence, classifies root causes, and recommends a lifecycle lane such as keep, observe, improve through Skill Factory hardening, merge with approval, or retire with approval" — with the outcome lanes enumerated. It matches the anchor for comprehensive concrete actions and is written in third person.

Completeness

It explicitly answers both questions: what it does (analyze evidence, classify root causes, recommend a lifecycle lane with the lanes named) and when to use it via a concrete "Use when a skill is not working…" clause. This matches the anchor for clear and explicit what-and-when with concrete trigger phrases.

Trigger Term Quality

The "Use when" clause covers natural phrases users would say ("a skill is not working", "not triggering correctly", "evals or Tessl disagree", "repeated failures need debugging"), but misses common variations like "skill is broken" or "skill keeps failing". Good keyword coverage with a few natural terms absent — fits anchor 4 rather than 5's comprehensive synonym coverage.

Distinctiveness Conflict Risk

The niche is clear (evidence-backed lifecycle decisions for failing skills) with distinct triggers like "evals or Tessl disagree", but phrases such as "a skill is not working" or "repeated failures need debugging" could plausibly trigger adjacent skill-maintenance or general debugging skills. Mostly distinct with minor overlap risk — anchor 4, not 5's minimal conflict risk.
