Conciseness

The opening paragraph — "Scale your AI context for coding agents. Make your next context work (skills, plugins & more) for your team, community, or self. Context engineering toolkit for AI coding agents." — is marketing tagline padding that repeats "for AI coding agents" and adds nothing actionable, and "This skill demonstrates a complete, self-referential example..." is meta commentary. The command list itself is tight, so this is 'mostly efficient but includes some unnecessary explanation', not 2 (only one padded paragraph) and not 4 (that paragraph could be cut entirely with no loss).

Actionability

Four copy-paste-ready commands with concrete paths ("doraval validate .", "doraval skill validate ./skills/doraval/", "doraval skill drift ./skills/doraval/", "doraval skill judge ./skills/doraval/") map each need to an exact invocation, and the closing rule "Always run `doraval validate` before sharing or publishing a plugin" is concrete. Not 4 — the commands cover all common cases with no gaps.

Workflow Clarity

"When you need to check a skill or Codex plugin:" pairs each scenario with an exact command, and the Codex test steps 1-4 form a clear sequence. Not 5 — there are no checkpoints on what to do with output (e.g., how to act on a drift report or failed validation); not 3 — sequences are explicit and complete rather than merely listed with implicit checkpoints.

Progressive Disclosure

The body is ~25 lines with no bundle files, so inline placement is appropriate, and content is logically grouped (commands, rule, test steps). Not 5 — there are no section headers to aid navigation, and it references ".agents/plugins/marketplace.json", a path that does not exist in this bundle; not 3 — given its size, nothing here clearly belongs in a separate file.

Specificity

"validate, measure drift, and judge skills and plugins" names the domain (doraval) and three concrete actions with explicit targets. Not 3 (more than 1-2 actions); not 5 (minor gaps — it never says what validation/judging entail, e.g., rubric-based scoring or lint rules).

Completeness

Both halves are explicit: what = "Use doraval to validate, measure drift, and judge skills and plugins"; when = "Use when authoring or reviewing context engineering artifacts for AI coding agents (works for Codex too)" with concrete trigger words. Not 4 — the when-clause is explicit and specific, not merely present-but-vague as the 4 anchor requires.

Trigger Term Quality

"skills and plugins", "authoring or reviewing", "AI coding agents", "Codex" give good coverage of natural terms a user would say. Not 5 (common variations like "check my skill's quality", "lint a plugin", or file-extension cues are missing); not 3 (keywords are relevant and go beyond a single generic phrase).

Distinctiveness Conflict Risk

A named tool (doraval) plus a clear niche — validating/judging AI agent skills and plugins — yields distinct triggers with minimal conflict risk; general code-review skills target code, not context artifacts. Not 4: the niche is clear and specific, not just "mostly distinct".
