Conciseness

The body is ~240 lines and restates the same iteration loop four ways — a mermaid flowchart (lines 33-57), Step Details (59-178), the Data flow diagram (204-238), and the Acceptance Criteria / 'What we do NOT want' sections (180-202). It is mostly efficient and free of concepts Claude already knows, but the cross-redundancy means it could be tightened. Not level 3 because the repeated representations of one loop are unnecessary tokens; not level 1 because it is not padded with beginner explanations.

Actionability

Provides fully executable, copy-paste-ready bash: jq filters ('.review.reviewScore // .weightedScore // .score'), rsync snapshot/revert, awk numeric comparison, and the devflow feeder block. Specific flags and env vars are named. Not level 2 because the code is complete and executable rather than pseudocode.

Workflow Clarity

The Iterate step sequences snapshot → apply → score → co-gate → keep/revert with explicit validation checkpoints, and the Acceptance Criteria table (G1-G7) provides a hard-gate checklist with feedback loops (revert on regression, revert entire run if G2 fails). Not level 2 because validation is explicit, not implicit.

Progressive Disclosure

The body offloads detail to a sibling 'REFERENCE.md' with clear one-level-deep signaling ('read REFERENCE.md (sibling)'), but no bundle files exist in references/scripts/assets and REFERENCE.md itself is absent — the reference points nowhere, so the actual bundle structure is empty. Additionally the main file carries the flowchart, step details, and data-flow sections inline where a single canonical representation would suffice. Not level 3 because the signaled reference does not resolve to an extant file; not level 1 because references are one-level-deep and clearly signaled rather than deeply nested.

Specificity

Lists multiple specific concrete actions: 'runs a Tessl-gated Ralph loop with snapshot-and-revert protection, never accepts a worse tessl review run score, and stops when no candidate change improves both the score and the structural quality.' This matches the level-3 anchor and exceeds level-2 (which would only name the domain and some actions).

Completeness

Explicitly answers both 'what' (iteratively optimizing an existing SKILL.md via a Tessl-gated loop) and 'when' (an explicit 'Use when...' clause plus a 'Triggers for...' list). Not level 2 because the 'when' is explicit, not merely implied.

Trigger Term Quality

Provides natural trigger phrases users would say — 'Triggers for /optimize-skill PATH, "make this skill better", "iterate on this SKILL.md", "improve this skill's tessl score"' — giving good coverage, not just technical jargon. It is not level 2 because common user phrasings are explicitly enumerated rather than merely implied.

Distinctiveness Conflict Risk

Has a clear niche — Tessl-gated skill optimization with snapshot-and-revert — and distinct triggers unlikely to fire for unrelated skills. Not level 2 because the combination of Tessl/iteration/score-gating is highly specific, not a broad overlap candidate.
