smart-contract-auditing SKILL.md skillA
smart-contract-auditing from nirholas/three.ws is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add nirholas/three.ws/smart-contract-auditing@git:20260501.87cefc9Pins git:20260501.87cefc9 in mdr.lock. Pin the fingerprint instead.

Complete mastery guide for smart contract security auditing — from first principles of EVM bytecode to advanced exploit patterns. Covers manual code review methodology, automated tooling (Slither, Mythril, Foundry fuzz), common vulnerability taxonomy (reentrancy, flash-loan attacks, oracle manipulation, access control, integer math), audit report writing, severity classification (Critical/High/Medium/Low/Informational), gas optimization reviews, upgrade safety, and DeFi-specific audit…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Smart Contract Auditing — From Zero to Expert This skill teaches you to think like a top-tier smart contract auditor. You'll learn to find vulnerabilities that automated tools miss, write clear findings, and reason about protocol-level risks in DeFi systems. ## The Auditor's Mindset > "Your job is not to confirm the code works. It's to prove it can break." An auditor must think adversarially. Every function is a potential attack surface. Every external call is a trust boundary. Every assumption is a vulnerability waiting to happen. ``` ┌─────────────────────────────────────────────────┐ │ AUDITOR'S MENTAL MODEL │ ├─────────────────────────────────────────────────┤ │ │ │ 1. UNDERSTAND the protocol's invariants │ │ 2. ENUMERATE every state-changing path │ │ 3. CHALLENGE every assumption │ │ 4. SIMULATE adversarial scenarios │ │ 5. VERIFY mitigations are complete │ │ │ │ "What must ALWAYS be true?" ← start here │ │ "How can I make it false?" ← then ask this │ …

How to install
mdr add nirholas/three.ws/smart-contract-auditing@sha256:8c9861a068c7c76cThe line at the top of this page pins the label git:20260501.87cefc9, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
