Conciseness

The body is dense and operational with no explanation of concepts Claude already knows, but the activation-vs-content-eval distinction is restated four times (Overview, Step 2, Step 5, "When to stop") and the stop-gate condition repeats across Step 2 and "When to stop" — minor over-explanation that could be trimmed, matching the 4 anchor rather than the lean 5.

Actionability

Guidance is fully executable: exact commands with flags ("tessl eval run <plugin-path> --skip-forced-context-activation --skip-scoring --label <run-label>"), a copy-paste skill-count command, explicit numeric thresholds (≥85% stop gate, ≥80% baseline triage, 2-iteration cap), and a complete report template covering fired/not-fired and cross-reference cases.

Workflow Clarity

Five clearly sequenced steps each carry entry/exit criteria or decision points, an explicit eval-ordering rule by skill count, feedback loops (re-run evals, compare before/after), an iteration cap, and a dedicated "When to stop" section — explicit validation checkpoints throughout, matching the 5 anchor.

Progressive Disclosure

No bundle files exist, and the skill is a clean orchestrator: all detail is appropriately delegated to three clearly-signaled sub-skills invoked per step, with well-organized section headers and easy navigation — matching the clear-overview / appropriately-split 5 anchor.

Specificity

The description lists six concrete actions spanning the entire cycle — "review best practices, generate eval scenarios, run BOTH activation evals … and content evals …, diagnose gaps, fix, and re-run until scores improve" — matching the comprehensive-coverage anchor rather than the minor-gaps anchor at 4.

Completeness

Both questions are explicitly answered: a clear "what" (the full cycle of concrete actions) and an explicit "when" ("Use when someone says 'optimize my skill'…"), matching the 5 anchor exactly rather than the 4 anchor where the "when" could be more explicit.

Trigger Term Quality

It quotes natural phrases users would actually say ("optimize my skill", "improve my plugin", "run evals", "benchmark my plugin") plus "wants to measure and improve", but misses common synonyms such as "evaluate", "test", or "score my plugin" — good coverage with a few natural terms missing, so 4 rather than 5.

Distinctiveness Conflict Risk

It occupies a clear niche (plugin eval/optimization) with distinct triggers, but phrases like "improve my plugin" and "run evals" overlap with its own closely related sub-skills (optimize-skill-instructions, setup-skill-performance) that a user might want individually — minor overlap risk with closely related skills, the 4 anchor rather than minimal-conflict 5.
