Conciseness

The body is ~55 lines of near-pure directive with no concept explanations Claude already knows, and each phase delegates detail to a reference file. Minor trimming is possible: the 'Consumer and interaction' section carries abstract phrasing ("Deliver a supported position in the form the intended consumer can use", "A person's request may need a brief answer or a shareable document") that could be tightened. Not score 3: there is no unnecessary explanation, only a few wordy sentences; not score 5: those wordy stretches exist.

Actionability

Guidance is concrete and executable for an instruction-only skill: exact reference files to read at each phase ("Read references/intake.md now, before any grounding"), exact config path ("docs_root from <repo-root>/.compound-engineering/config.yaml"), exact command ("git rev-parse --show-toplevel"), and defined failure returns ("Blocked — missing context"). Not score 5: the panel/scout mechanics themselves are delegated to references rather than shown, so the body alone leaves minor execution gaps.

Workflow Clarity

A clearly sequenced Phase 0–4 pipeline (Frame → Ground → Verify → POV → Deliver) with explicit validation checkpoints: Phase 2 is dedicated to verifying grounding with a defined failure path ("If the evidence falls short, no subject shape may return a confident result; that reference names the result each shape returns instead"), missing context returns a structured Blocked result, and an invalid docs_root stops with a named error instead of falling back. Not score 4: the checkpoints and their failure handling are explicit, not implicit.

Progressive Disclosure

The body is a genuine overview that splits per-phase detail into one-level-deep references, each signaled with its purpose and read-order at the point of need (intake.md, boundaries.md, grounding.md, method.md, cross-model-panel.md, followup.md — all present in references/, along with scripts/cross-model-pov.sh, scripts/peer-job-runner.py, and four files under references/agents/). Not score 4: every referenced path resolves, each reference is clearly labeled with what it defines, and nothing bulk that belongs in a reference is inlined (the ce-docs-root block is short and required before any artifact path is composed).

Specificity

The description names the domain ("Judge a supplied subject against the project's evidence and constraints") and several subjects ("external-adoption question", "a holistic take on a document", "a supplied approach set"), but these are variations of one abstract judging action rather than multiple distinct concrete operations like 'extract text' or 'fill forms'. Not score 4: the verbs (judge, assess, consult, reconcile) stay abstract and no concrete deliverable is named; not score 2: the domain is clearly named and more than one action is enumerable.

Completeness

Both parts are explicit: the 'what' is "Judge a supplied subject against the project's evidence and constraints" and the 'when' is a concrete "Use when..." / "Use for..." list covering four trigger scenarios, plus routing disambiguation ("Use ce-explain for understanding and ce-doc-review for findings review"). Not score 4: the 'when' is not merely present but enumerates specific triggering situations rather than a generic clause.

Trigger Term Quality

Trigger phrases are natural for the domain — "assessing an external-adoption question", "a holistic take on a document", "a supplied approach set", "an oracle panel to consult other models and reconcile their opinions" — and a user needing this skill would plausibly say them. Not score 5: common synonyms like 'second opinion', 'evaluate this approach', or 'cross-check' are absent from the description itself (cross-check appears only in the argument-hint); not score 3: coverage across several distinct trigger scenarios is solid.

Distinctiveness Conflict Risk

The niche is clear (forming a project-grounded verdict/POV) and the description actively de-conflicts by routing sibling use cases elsewhere ("Use ce-explain for understanding and ce-doc-review for findings review"). Triggers (oracle panel, external-adoption question, document take) are distinct enough that wrong-skill triggering is minimal. Not score 4: no meaningful overlap risk remains given the explicit sibling routing.
