Conciseness

The body is ~650 lines with several padded sections: two large ASCII diagrams, a "MANDATORY COMPLIANCE" section that repeats the same prohibition four ways, the same orchestrate.sh invocations re-listed in Quick Start and again per-phase, a cost table with dollar estimates, and provider subscription-tier tables — much of this is not knowledge Claude lacks. It is not a 1 because it never explains basic external concepts (e.g., what a CLI is) and most sections do carry operational content.

Actionability

Commands are concrete and copy-paste ready throughout — full invocations like `orchestrate.sh probe "..."` with realistic prompts, a prerequisites check with exact expected output and status values, a routing table, and per-option defaults. Not 5 because several commands reference behavior that is only named, not specified (what `spawn <agent>` does, how `--context` glob patterns resolve), and outputs like `probe-synthesis-*.md` are shown without how to consume them.

Workflow Clarity

The Double Diamond sequence is clearly ordered with explicit context chaining (`--context grasp-consensus-*.md`), validation checkpoints exist (preflight, detect-providers with status-based routing, tangle quality gates at 90/75% thresholds), and Troubleshooting covers failure recovery. Not 5 because the failure loop is only loosely closed — a FAILED gate just means "Ink phase flags for review" with no explicit fix-and-revalidate step in the workflow itself, and the batch-parallel dispatch path has no verification of sub-agent results.

Progressive Disclosure

Section structure is real and consistent (Quick Start, phases, Command Reference, Troubleshooting), so it is above the 'minimal structure' anchor. But roughly 300 lines of command reference, agent tables, and provider config examples are inlined that clearly belong in separate reference files, no bundle files exist at all, and the one body reference — `skills/blocks/codex-host-adapter.md` — does not resolve to a real file in this bundle.

Specificity

The description names the domain ("parallel agents") and one concrete action ("Decompose large tasks"), matching the anchor 'Names domain and 1-2 concrete actions, but not comprehensive'. It does not reach 4 because no further specific actions (e.g., fan-out, map-reduce, adversarial review, quality gates) are listed, even though the skill body contains many.

Completeness

Both 'what' ("Decompose large tasks across parallel agents") and 'when' ("use for migrations, multi-file refactors, or batch work") are explicitly present, so it clears the score-3 cap for a missing when-clause. Not 5 because the 'what' is thin relative to the skill's actual scope — it omits the Double Diamond workflow, adversarial cross-model review, and auto-routing that dominate the body — leaving the when-clause without a fully concrete counterpart.

Trigger Term Quality

"use for migrations, multi-file refactors, or batch work" provides good natural keyword coverage that users would plausibly say. Not 5 because common synonyms and phrasings users actually use for this skill's core behavior ("parallelize", "fan out", "run tasks concurrently", "multi-provider", "orchestrate") are missing.

Distinctiveness Conflict Risk

The trigger list (migrations, multi-file refactors, batch work) is concrete and gives it a recognizable niche with mostly distinct triggers. Not 5 because "Decompose large tasks across parallel agents" is a crowded capability that overlaps generic subagent-delegation and orchestrator skills, and the description gives no distinguishing signal (multi-provider, Double Diamond, adversarial review) that would separate it from those.
