Conciseness

The body is lean and assumes Claude's competence: no explanations of what plans or agents are, no padding, and every section (Collect → Normalize → Cross-Review → Decide → Handoff) carries actionable guidance, matching the "every token earns its place" anchor.

Actionability

Concrete, executable guidance throughout: a 7-item extraction checklist, a 5-criteria tie-break order, three named decision outcomes, and a copy-paste-ready decision memo template. As an instruction-only skill, the absence of code is not penalized because the guidance is specific and directly actionable.

Workflow Clarity

The numbered 5-step workflow has explicit validation ("verify claims against the repo", "one execution handoff with verification gates"), a feedback loop for error recovery (the "Revise first" outcome sends plans back for another pass), a normalization checklist, and an approval checkpoint ("stop at the handoff and ask for approval"); planning is read-only, so the destructive-operation cap does not apply.

Progressive Disclosure

The single ~110-line file is well-organized with clear section headers and no buried content, but no bundle files exist and nothing is split out — the decision-memo template and cross-review checklist are reasonable candidates for a one-level-deep reference file, so it fits "good structure; minor organization gaps" rather than the well-signaled reference structure of a 5.

Specificity

The description lists several specific actions ("compare, cross-review, merge, judge, choose, or arbitrate competing plans") anchored to a concrete domain ("multiple agents such as Codex and Claude Code"), but the verbs are one action-family around a single capability rather than a comprehensive set of distinct actions, so it sits at 4 rather than 5.

Completeness

The "when" is explicit and multi-faceted ("Use when asked to...; when given two or more proposed plans...; or when the user wants one recommended execution plan..."), but the "what" is only embedded inside when-clauses — there is no declarative capability statement like "Compares and merges competing plans into one recommended plan", so it does not reach the explicit what-plus-when of a 5.

Trigger Term Quality

Good coverage of natural terms users would say — "compare", "merge", "judge", "arbitrate", "plans", "session IDs", "transcripts", "PR descriptions", "Codex and Claude Code" — though common phrasings like "which plan is better" or "pick the best plan" are absent, keeping it below the comprehensive-synonym coverage of a 5.

Distinctiveness Conflict Risk

"Competing plans from multiple agents such as Codex and Claude Code" carves a clear niche with distinct triggers, but there is minor overlap risk with general planning, review, or code-review skills, matching the "mostly distinct; minor overlap risk" anchor rather than a 5.
