Conciseness

The body is ~640 lines with no padding about concepts Claude already knows, but it duplicates content: the Mode A "8 quick-check items" are restated nearly verbatim in the Invariants reference (e.g. dead links / E-1, backlog completeness / E-12, ADR references / E-3), and the Caps table is an acknowledged mirror of another file ("the table below is a mirror and must be kept hand-aligned"). The templated console-report block with {n} placeholders could also be tightened.

Actionability

Guidance is fully concrete and executable: exact glob patterns for node discovery ("_devprocess/requirements/epics/EPIC-*.md"), exact frontmatter fields to parse ("feature-refs, adr-refs, fix-refs, imp-refs"), a per-finding-type fix dispatch table, exact marker syntax ("FIXME(stub): <reason> -- see FIX-{ee}-{ff}-{nn}"), and copy-paste commands ("bash <DIA-checkout>/tools/install-git-hooks.sh").

Workflow Clarity

The six-step Workflow is clearly sequenced with an abort condition if structure detection fails, and Mode C is a genuine feedback loop: load -> triage -> per-finding fix -> re-check (Mode A re-run) -> commit confirmation -> follow-up, with AskUserQuestion checkpoints at every step. Validation for risky batch behavior is explicit (escalation on shared-infrastructure or substance-deleting fixes, non-auto-fixable findings left for human triage) and a quality-gates checklist guards completion.

Progressive Disclosure

Section structure is clear, but content that clearly belongs in reference files is inlined: the full ~140-line invariants reference (whose stated source of truth is skills/project-conventions/references/graph-invariants.md) and the mirrored caps table both live in the SKILL.md body. External file pointers are plain code paths rather than clearly signaled navigable references, and no bundle files (references/, scripts/, assets/) exist to offload this detail.

Specificity

Enumerates concrete checked artifacts ("BA sections, Epics, Features, Success Criteria, ADRs, arc42 sections, PLANs, Backlog, Wayfinder rows, and code references") and names both check modes ("syntactic (links, IDs, Refs) and semantic (content coherence via an agent)"). The core action "Verifies the V-Model artifact graph is intact" is slightly generic relative to the anchor-5 examples of multiple distinct operations, so minor coverage gaps remain.

Completeness

Explicitly answers both what (verifies the V-Model artifact graph via syntactic and semantic modes, with default-run timing rules) and when, with a concrete "Use this skill when the user mentions..." clause listing trigger phrases. This matches the anchor-5 example pattern of capabilities followed by explicit trigger conditions.

Trigger Term Quality

Includes natural phrases users would say ("consistency check", "graph check", "check references", "dead links", "orphan features", "graph-health") plus a programmatic trigger ("when another V-Model skill completes a phase"). Some natural variations are missing, e.g. "Konsistenzpruefung" and "backlog health" appear only in the body's Keywords section, not the description.

Distinctiveness Conflict Risk

The V-Model artifact-graph niche is distinct and the inter-skill trigger is purpose-built. However, generic phrases like "check references" and "dead links" could plausibly fire in non-V-Model contexts (general link linting), a minor overlap risk with generic lint/checker skills.
