Conciseness

The body is lean — bullet lists, commands, and error/fix pairs with no explanation of concepts Claude already knows — but it duplicates the same validate_jtbd.py invocations in both "How to Use" and "Workflow", and the mock "Example Interactions" dialogue is padding, fitting anchor 4's minor-trimmable-instances rather than anchor 5's every-token-earns-its-place. It is well above anchor 3 since no unnecessary conceptual explanation exists.

Actionability

Commands are copy-paste ready and verified real ("python3 .claude/skills/jtbd-validator/scripts/validate_jtbd.py path/to/job.md ." points to an existing script), the batch loop and find command are executable as written, and common errors are shown with concrete error strings and fixes, matching anchor 5's fully-executable comprehensive coverage.

Workflow Clarity

The "When User Requests Validation" section gives a clear 4-step sequence (identify files → run validator → report results → explain fixes) with an error-handling branch, fitting anchor 4. It falls short of anchor 5 because there is no explicit re-validate-after-fix feedback loop for the batch (validate-all) path, and above anchor 3 because checkpoints (validator pass/fail with exit codes 0/1) are explicit rather than implicit.

Progressive Disclosure

Sections are well organized and the heavy logic correctly lives one level deep in a real, clearly-signaled script (scripts/validate_jtbd.py, verified present) with nothing inlined that belongs elsewhere, fitting anchor 4. Not anchor 5 because the body has no clearly-signaled reference/navigation structure beyond the script — the "Common Errors & Fixes" section and mock interactions are reasonable inline, but the ~95-line body offers only the single script reference rather than a well-signaled reference set.

Specificity

"Validate JTBD (Jobs-to-be-Done) markdown files for correctness and completeness" names the domain and a single action ("validate"), but does not enumerate the concrete checks performed (frontmatter, step dependencies, API URNs, operationIds), matching the anchor for 1-2 concrete actions without comprehensive coverage. It falls short of anchor 4, which expects several specific actions listed, and above anchor 2 because the domain is clearly named with a real action.

Completeness

It clearly answers both questions: the first sentence states what it does ("Validate JTBD... markdown files for correctness and completeness") and the second gives an explicit "Use when..." clause with concrete quoted trigger phrases, exactly matching anchor 5.

Trigger Term Quality

The explicit triggers "validate JTBD", "check JTBD", "verify workflow", and "lint JTBD" give good natural keyword coverage including a synonym ("lint"), but common variations like "check workflow" or file-extension terms are missing, fitting anchor 4 rather than the comprehensive synonym-plus-extension coverage of anchor 5. Above anchor 3 because multiple natural phrases users would actually say are present.

Distinctiveness Conflict Risk

JTBD validation is a clear niche with distinct triggers, but the trigger "verify workflow" is generic and could plausibly fire for unrelated workflow-verification requests, giving minor overlap risk per anchor 4. Not anchor 5 because of that generic trigger; not anchor 3 because the JTBD-specific terms are highly distinctive.
