Conciseness

The body is directive and lean throughout ("Locate the source image/model...", "Classify the actor as character or monster", "Never overwrite the high-detail source") with no padding or explanation of concepts Claude already knows; every line earns its place.

Actionability

Concrete, executable guidance is pervasive: exact file paths, template names, the command `scripts/validate_asset_manifest.py <manifest>` with `--root <repo>` and `--require-verified` flags, explicit slot and action-role lists, and specific verification actions.

Workflow Clarity

A clear sequenced workflow (contract first → common package → character/monster profiles → catalog lab → verify and commit) with explicit validation checkpoints (run validator before building, re-run with flags, browser verification checklist) and a feedback loop around acceptance checks.

Progressive Disclosure

SKILL.md is an overview with well-signaled, one-level-deep references to real files (requirements.md, catalog-and-testing.md) plus assets/ templates and a scripts/ validator, all of which exist in the bundle; detailed content is appropriately split out.

Specificity

The description enumerates multiple concrete actions ("Create, integrate, or audit", "main model, skeleton, animation library, sockets, collision contracts, separate character equipment, optimized runtime files, catalog media, and an interactive moveset inspector") with comprehensive coverage, matching the score-5 anchor.

Completeness

It explicitly answers both what ("Create, integrate, or audit production-ready rigged 3D characters and monsters...") and when ("Use when generating or importing FBX/GLB game actors; defining character-versus-monster asset requirements...") with concrete trigger phrases.

Trigger Term Quality

It includes natural trigger terms plus file extensions and synonyms — "FBX/GLB game actors", "separating swords, shields, helmets, armor, or stowed gear", and a full list of animation clips (idle, walk, run, attack, hit, dodge, block, cast, death) — giving comprehensive coverage of what users would say.

Distinctiveness Conflict Risk

The niche is clearly defined — rigged 3D game character/monster asset pipelines with FBX/GLB, equipment separation, and animation libraries — with distinct triggers and minimal overlap with other skills.
