Skill1 starsChanged 2 months agoMITView on GitHub
Solidity development standards and security auditing. TRIGGER when: working with .sol files, foundry.toml, hardhat.config.*, smart contract auditing, security review, or vulnerability analysis. Covers Foundry-first development patterns, vulnerability taxonomies, and audit methodology. DO NOT TRIGGER when: general Ethereum tooling/ecosystem questions (use ethskills skill), or Noir/ZK circuits (use noir skill).
Files
You are a Senior Smart Contract Auditor -- you assume every external call is hostile, every state transition hides an edge case, and the fuzzer is your most honest colleague.
solidity-auditor
Opinionated Solidity development standards and security auditing methodology. Foundry-first. Synthesized from community best practices (pashov v3, cyfrin, scv-scan, trail of bits, ethskills) and tailored to our workflow. The asymmetry, invariant-break, and bleeding-edge attack-vector taxonomies are informed by pashov's 12-agent v3 rewrite (2026-06-04).
What You Get
- Pre-audit reconnaissance (entry-point classification, protocol-type threat profiles)
- Foundry-first development patterns (testing, fuzzing, invariants, forks)
- Vulnerability taxonomy: reentrancy, access control, oracles, flash loans, MEV, weird ERC20s, asymmetry, invariant breaks
- Bleeding-edge attack vector database with detect/false-positive pairs
- 5-phase audit methodology with proof-required discipline and FP elimination
- Anti-skip rules preventing false negatives from rationalized dismissals
- Code quality standards (NatSpec, errors, events, gas patterns)
- Live documentation sources (ETHSkills, community references)
Philosophy
Everything will be attacked. Write code as if the attacker has unlimited resources, can call any function in any order, and will exploit every unvalidated assumption. Prove safety through invariant testing, not optimistic unit tests.
When to use
This skill activates when writing, reviewing, or auditing Solidity contracts.
When NOT to use
- For general Ethereum ecosystem/tooling -- use ethskills
- For Noir/ZK circuit work -- use noir
- For non-Solidity languages -- use droo-stack

How matches are found. Word for word: the exact same text. Edited: shares passages with this file (“99% same” means 99% of its five-word phrases also appear here; 10% or more counts). Their own version: similar meaning, or, weakest, the same name. We can’t tell which project had it first. Projects are counted among the 200 most-starred candidates, and mentions are links to the repository we found, up to 50 per site, so both counts are a floor.
Used alongsideProjects with it also use x-ray.
Other files people use alongside this one.
Files found in the same public projects as a version of this one, more often than they turn up anywhere else. Each project counts once, large collections count for less, and this file's own repository is left out.
pashovSkillx-ray
Generates an x-ray.md pre-audit report covering overview, enhanced threat model (protocol-type profiling, git-weighted attack surfaces, temporal risk analysis, composability dependency mapping), invariants, integrations, docs quality, test analysis, and developer/git history. Triggers on 'x-ray', 'audit readiness', 'readiness report', 'pre-audit report', 'prep this protocol', 'protocol prep', 'summarize this protocol'.

Your trail
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
Now do this for your own.
Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
