Conciseness

The body is three lean sections: a playbook routing table, an 8-step numbered workflow of concrete commands, and a severity-tier table. It assumes Claude's competence (no explanation of what reentrancy or Slither is) and every token earns its place, matching the 5 anchor.

Actionability

Steps are executable with concrete commands ('bash("find /workspace/src -name *.sol | head -50")', 'slither . --json slither.json', 'forge test -vvv --match-contract Test_') and named tool calls ('solidity_scan_file', 'slither_ingest', 'kg_query'). Not a 5: step 6's 'foundry_reentrancy_test etc.' leaves the per-vulnerability test generators vague, and no example PoC snippet is shown.

Workflow Clarity

The 8-step sequence is clearly ordered from mapping to promotion, and there is a pass/fail gate (run 'forge test', then 'Promote passing PoCs as validated findings'). Not a 5: no explicit feedback loop for failing PoCs (fix/retry/discard guidance) and no baseline negative-control step in the body, though the workflow is not destructive so no cap applies.

Progressive Disclosure

Under 50 lines with well-organized sections and no inlined bulk content; per-vulnerability detail is pushed one level deep to sibling SKILL.md files via a clearly labeled routing table. This matches the small-skill exception (under 50 lines, no external reference files needed) for a top score.

Specificity

The description lists multiple concrete capabilities — 'Solidity/EVM pattern scanner', 'Slither ingestion', 'Foundry PoC generation', 'DeFi attack playbooks' — covering scan, ingest, PoC, and playbook layers with no vague filler. This matches the 5 anchor (multiple specific concrete actions, comprehensive coverage) and exceeds the 4 anchor, which implies coverage gaps; none are evident within the stated domain. It uses third person voice, so no person-penalty applies.

Completeness

The 'what' is clear (scanner, Slither ingestion, PoC generation, playbooks), but there is no 'Use when...' clause or equivalent explicit trigger guidance in the description, which caps completeness at 3 per the judging guidelines. Not a 2 because the 'what' is concrete and comprehensive, not vague.

Trigger Term Quality

Strong natural keywords: 'smart contract', 'Solidity', 'EVM', 'Slither', 'Foundry', 'DeFi', 'audit' — exactly what a user in this domain would say. Not a 5 because common variations like 'web3', 'blockchain', 'exploit', or 'security review' are absent.

Distinctiveness Conflict Risk

It occupies a clear niche (smart contract / EVM security auditing) with domain-specific triggers (Slither, Foundry, DeFi) that virtually no other skill type would claim, matching the 5 anchor's 'clear niche with distinct triggers; minimal conflict risk'.
