Conciseness

The body assumes Claude's competence (never explains what MCP servers or plugins are) and stays lean — file lists, a decision table, and output structure with no filler. Minor trimmable redundancy keeps it at the 4 anchor: the three-way available/primitive/missing taxonomy appears twice ("already available now / available but not wrapped well / not available" in Non-Negotiable Rules, then again as the Parity / Primitive-only gaps / Missing integrations output sections), and "Inspect only the files and settings needed to answer the question well" is throat-clearing.

Actionability

For an instruction-only skill the guidance is concrete: exact files to inspect (".mcp.json", ".claude/settings*.json", "package.json"), named env key examples ("STRIPE_API_KEY", "TWILIO_AUTH_TOKEN"), a gap-to-shape decision table, a fixed five-section output format, and illustrative callouts ("Stripe is available via connected app, but ECC lacks a billing-operator skill"). It falls short of fully executable because no concrete commands are given for the inventory phase (e.g. how to list installed plugins, enabled connectors, or MCP servers), leaving the executor to discover those.

Workflow Clarity

The three phases (Inventory → Benchmark → Decide) are clearly sequenced, Phase 2 supplies per-item checkpoint questions ("what they actually do / whether ECC already has parity / only primitives / missing entirely") and "Good Outcomes" defines success criteria. It sits at the 4 anchor rather than 5 because there is no explicit validation step confirming inventory claims against actual file contents before recommendations are made — a minor checkpoint gap, though the skill is read-only so no destructive-operation cap applies.

Progressive Disclosure

The skill is self-contained with no bundle files and no content that warrants splitting out — every section is short, well-labeled, and belongs in the main file, and navigation is easy via the clear heading hierarchy. Per the scoring notes, a skill with no need for external references can score 5 with well-organized sections, which this matches; nothing is inlined that should live in a separate reference.

Specificity

The description lists multiple concrete actions across a comprehensive surface: "Audit the active repo, MCP servers, plugins, connectors, env surfaces, and harness setup, then recommend the highest-value ECC-native skills, hooks, agents, and operator workflows." Both the audit inputs and the output artifact types are enumerated specifically, matching the comprehensive anchor rather than the 4 anchor which has minor coverage gaps.

Completeness

Both halves are explicit: the "what" is stated concretely (audit listed surfaces, then recommend ECC-native skills/hooks/agents/workflows) and an explicit "Use when..." clause gives concrete trigger conditions. This matches the anchor requiring both what and when with concrete trigger phrases; not the 4 anchor where "when" could be more specific.

Trigger Term Quality

"Use when the user wants help setting up Claude Code or understanding what capabilities are actually available" contains natural phrases users would say, but common variations present in the body's When to Use list ("what plugins or MCPs should I use?", "recommend automations", "what am I missing?") are missing from the description itself. Good coverage with a few natural terms missing — the 4 anchor — not the comprehensive synonym coverage of 5.

Distinctiveness Conflict Risk

The ECC-native framing ("ECC-native skills, hooks, agents", "connectors, env surfaces") carves out a clear niche, but the trigger "help setting up Claude Code" is broad enough to overlap with general setup/config skills, putting it at the 4 anchor (mostly distinct, minor overlap with closely related skills) rather than 5 (minimal conflict risk).
