Conciseness

The body is lean with no concept explanations or padding — every line is scope, navigation, or a guardrail ("Use when your CLAUDE.md is long but AI still ignores your rules", "Stop and ask for clarification if required inputs... are missing"). Nothing identifiable could be trimmed, so it is above level 4.

Actionability

The only executable directive in the body is "Read [the detailed guide](references/detailed-guide.md) before executing this skill" — the concrete steps, commands, and example rewrites all live one level away in the reference. This matches "minimal concrete guidance; high-level hints but missing the specific steps to execute". Not level 3 because the body contains no inline quick-start, example, or command; not level 1 because the pointer is a specific, real instruction plus concrete stop conditions.

Workflow Clarity

The sequence in the body is only "read the guide → execute", and while validation is declared ("Treat its safety, prerequisites, and validation requirements as mandatory"), no actual checkpoint appears in the body. Since the skill's operation replaces a user's live CLAUDE.md (destructive-adjacent) and the body itself lacks validation steps, workflow clarity is capped at 3. Not level 4 because checkpoints are delegated rather than present; not level 2 because the delegation is explicit and the stop-and-ask conditions give a rough but stated frame.

Progressive Disclosure

Verified against the actual bundle: the single reference references/detailed-guide.md exists, is clearly signaled with a markdown link, is one level deep, and itself contains no nested references. The body is a clean overview (guide pointer, when-to-use, limitations) with trivial navigation. Not level 4 because the split is appropriate and there are no organization gaps to point to.

Specificity

"Convert human-written CLAUDE.md into AI-native structured-label format" and "Propose and evaluate structured-label rewrites" name the domain plus 1-2 concrete actions, but coverage of the full workflow (measuring, testing, migrating) is absent. It is above level 2 because the actions are concrete rather than generic, but below level 4 because it does not list several specific actions.

Completeness

The "what" is clear (convert CLAUDE.md to structured labels; propose and evaluate rewrites), but there is no "Use when..." clause or equivalent trigger guidance, which caps completeness at 3. Not level 4 because "when" is entirely missing rather than merely imprecise.

Trigger Term Quality

"CLAUDE.md" is the one genuinely natural keyword, but common user phrasings like "system prompt", "reduce token usage", or "rules" are missing. Not level 4 because there is no synonym or variation coverage; not level 2 because the present keyword is specific to the artifact, not generic.

Distinctiveness Conflict Risk

"human-written CLAUDE.md" conversion is a clear niche with a distinct artifact trigger, giving minimal conflict risk. Not level 5 because the broader prompt-optimization scope creates minor overlap with generic prompt-engineering skills; not level 3 because the CLAUDE.md artifact keeps it well distinguished.
