Conciseness

The body is dense and table-driven with almost no padding — nearly every line is host-specific runtime fact Claude cannot reliably know. Minor redundancy keeps it below a 5: the `claude plugin validate` advice ("v2.1.233 or later") and the strict-YAML portability warning each appear in both the Host reference and Step 2.

Actionability

Fully executable throughout: copy-paste discovery commands (`find -L .claude/agents -name "*.md"`), a point-by-point scoring rubric with per-criterion point values, a complete report template, concrete edge cases with fixes, and per-step "Done when" exit criteria.

Workflow Clarity

Steps 1-6 are clearly sequenced with explicit validation checkpoints (loadability via `claude plugin validate`, collision checks, "Done when" gates per step), a triage mode for >20 agents, and an explicit confirmation gate before file deletion — so the destructive/batch validation cap does not apply.

Progressive Disclosure

No bundle files exist; the ~90-line Host reference (load precedence, silent-skip rules, the full frontmatter field table, Codex schema) is inline lookup material that loads on every invocation and clearly belongs in separate reference files (e.g., references/claude-code.md, references/codex.md). Section headers give it structure, but content that should be separate is inlined.

Specificity

The description enumerates five concrete check dimensions ("loadability against the native schema, description overlap, model tier, tool scope, and headless-safe instructions") with explicit file paths for both hosts, giving comprehensive coverage of what the skill audits.

Completeness

It explicitly answers both what ("Audit custom subagent definitions ... loadability ... description overlap, model tier, tool scope, and headless-safe instructions") and when ("Use when onboarding to a project with agents, after adding or importing agents, or when the parent agent delegates to the wrong agent") with concrete trigger phrases.

Trigger Term Quality

Natural triggers like "onboarding to a project with agents", "after adding or importing agents", and "delegates to the wrong agent" are present alongside file extensions, but common synonyms users might say ("check my agents", "agent hygiene", "review agents") are missing.

Distinctiveness Conflict Risk

The niche is narrow and clearly bounded — custom subagent definition files for two named hosts with explicit paths — and the trigger scenarios (wrong delegation, agent import) are distinct from generic evaluation skills, so conflict risk is minimal.
