Conciseness

The body is dense and operational — tables for modes and stages, no tutorials on concepts Claude already knows — but the opening paragraph repeats the frontmatter description almost verbatim, the execution rules and GATEs partially restate each other (e.g. rule 4 vs GATE-U4, rule 2 vs GATE-U5), and the runtime-probe section is wordier than needed. Not 5 due to this duplicated material; not 3 because the padding is minor, not whole unnecessary sections.

Actionability

Concrete, executable guidance throughout: exact command flags (--map, --trace <entry>), exact file-reference and flow formats, named JSON outputs (context-map.json, flow-trace-<id>.json, variants.json), and a precise checklist-item schema table. As an instruction-only skill the absence of code is not penalized. Not 5 because some operational details are unresolved in-body ('output_dir: resolved by raptor-run-lifecycle' defers a value without a pointer, and how/where the modes are invoked is never shown); not 3 because the guidance goes well beyond high-level hints.

Workflow Clarity

The Stages table cleanly sequences mode → gates → output, the execution rules are numbered, and the gates act as explicit checkpoints (READ-FIRST, EVIDENCE-ONLY confidence matching is effectively a validation gate). Not 5 because there is no explicit feedback/error-recovery loop and the Stage table omits Study (which appears in the Modes table), leaving a minor gap; not 3 because checkpoints are explicit and the sequence is coherent.

Progressive Disclosure

The body is well-sectioned and explicitly defers detail ('See stage-specific files for detailed instructions', 'MAP-7 in map.md'), but the bundle contains no stage-specific files — no references/, scripts/, or assets/ exist, and map.md is referenced by name without a path or link, so the signaled references dangle. Per the guideline to score against the actual bundle structure, the clearly-signaled one-level references point at files that are not present, leaving navigation broken despite good in-file organization. Not 2 because the SKILL.md itself is appropriately split and the references are clearly signaled, not buried; not 4 because referenced files cannot actually be reached.

Specificity

Names the domain ('security research') and several concrete actions — 'mapping architecture, tracing data flows, and hunting vulnerability variants' — which is several specific actions with minor gaps ('build ground-truth understanding' is more abstract than an action). Not 5 because the closing purpose phrase is abstract and coverage of the modes (study/teach) is not indicated; not 3 because the action list clearly exceeds 1-2 concrete actions.

Completeness

The 'what' is clear (map architecture, trace data flows, hunt variants), but there is no 'Use when...' clause; the only temporal hint is 'before or alongside static analysis', which weakly implies when. The judging guideline caps completeness at 3 for a missing explicit trigger clause; not 2 because the 'what' is concrete, not vague.

Trigger Term Quality

Relevant keywords exist ('architecture', 'data flows', 'vulnerability variants', 'static analysis') but common natural variations are missing — no 'understand this codebase', 'audit', 'trace this input', 'taint', or file-type hints. Not 4 because a user needing code comprehension would not naturally say 'adversarial code comprehension' or 'ground-truth understanding'; not 2 because several genuinely relevant domain terms are present.

Distinctiveness Conflict Risk

The niche (adversarial comprehension for security research complementing static analysis) is fairly distinct from general code-review or document skills. Not 5 because it could still overlap with generic 'understand/analyze this code' requests or a security-review skill given no explicit trigger scoping; not 3 because the security-research framing and pre-scan positioning give it a clear niche.
