Conciseness

The 72-line body is lean and assumes Claude's competence: every section instructs rather than explains ("Prefer JSONL for append-only ledgers and Markdown for human summaries"), with no padding or concept explanations. It matches the "every token earns its place" anchor.

Actionability

Concrete guidance throughout — a specific ledger field checklist, a 7-step rollout loop, and copy-paste-ready example blocks for the coherence mark and summary — but "Run the bounded search" and ledger storage details (path/format) remain unspecified. Mostly actionable with minor gaps, not the fully executable coverage of anchor 5.

Workflow Clarity

The 7-step "Rollout Loop" is clearly sequenced and includes real validation checkpoints (marking in step 4, downgrade-on-failed-replay in step 6, and explicit promotion gates), so it avoids the missing-validation cap. It falls short of anchor 5's full error-recovery feedback loops and checklists — e.g., what to do when a replay gate fails beyond downgrading.

Progressive Disclosure

A single-file skill with clean, well-signaled sections (Ledger Contract, Rollout Loop, Coherence Mark, Promotion Rules, Summary Shape) and no external references — appropriate since nothing clearly belongs in a separate file. However, the body exceeds the under-50-lines condition under which well-organized sections alone earn a 5, placing it noticeably above anchor 3 but below the clear 5.

Specificity

Names two concrete actions — "Run repeated rollouts... keeping an append-only decision ledger of trials, marks, coherence checks, and promotion gates" — with detailed scope, but lacks the multiple distinct actions of the 5 anchor. It sits noticeably above the 1-2-action coverage of anchor 3 but below comprehensive multi-action coverage.

Completeness

Explicitly answers what ("Run repeated rollouts... keeping an append-only decision ledger... so recursive confidence never auto-approves live trading, deploy, or destructive actions") and when ("Use when the user asks for repeated rollouts...") with concrete trigger phrases. Both halves match the 5 anchor exactly; no lower anchor fits.

Trigger Term Quality

The trigger list "repeated rollouts, marked decision processes, high-dimensional search, stochastic optimization, local-optima exploration, ensemble comparison, or recursive reasoning with a visible evidence trail" comprehensively covers the natural phrases a user would say, including synonyms and the distinctive "Prime Gauss" term.

Distinctiveness Conflict Risk

A niche domain (recursive rollout prompting with a decision ledger) with distinctive triggers, but broader terms like "high-dimensional search" and "stochastic optimization" create minor overlap risk with general optimization/research skills. Mostly distinct rather than a clear isolated niche.
