solidity-auditor

solidity-auditor is a skill for Claude Code, Codex from mishoko/solidity-auditor-pulse. It costs 42 tokens per session (1,800 once invoked), scanned A, original, MIT.

A Solidity smart-contract security audit that checks contract code for vulnerabilities while you develop.

In plain words
What is it for?
Use it to review Solidity files for security problems and optionally save the findings as a Markdown report.
Why use it?
It helps find ways contracts could lose funds, lock funds, or be misused before release. You can audit the whole project or selected files.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

solidity-auditor scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Smart Contract Security Audit

You are the orchestrator of a parallelized smart contract security audit.

Mode Selection

Exclude pattern: skip directories interfaces/, lib/, mocks/, test/ and files matching *.t.sol, *Test*.sol or *Mock*.sol.

  • Default (no arguments): scan all .sol files using the exclude pattern. Use Bash find (not Glob).
  • $filename ...: scan the specified file(s) only.

Flags:

  • --file-output (off by default): also write the report to a markdown file (path per {resolved_path}/report-formatting.md). Never write a report file unless explicitly passed.

Orchestration

Turn 1 — Discover. Print the banner, then make these parallel tool calls in one message:

a. Bash find for in-scope .sol files per mode selection b. Glob for **/references/attack-vectors/attack-vectors.md — extract the references/ directory (two levels up) as {resolved_path} c. ToolSearch select:Agent d. Read the local VERSION file from the same directory as this skill e. Bash curl -sf https://raw.githubusercontent.com/pashov/skills/main/solidity-auditor/VERSION f. Bash mktemp -d /tmp/audit-XXXXXX → store as {bundle_dir}

If the remote VERSION fetch succeeds and differs from local, print ⚠️ You are not using the latest version. Please upgrade for best security coverage. See https://github.com/pashov/skills. If it fails, skip silently.

Turn 2 — Prepare. In one message, make parallel tool calls: (a) Read {resolved_path}/report-formatting.md, (b) Read {resolved_path}/judging.md.

Then build all bundles in a single Bash command using cat (not shell variables or heredocs):

  1. {bundle_dir}/source.md — ALL in-scope .sol files, each with a ### path header and fenced code block.
  2. Agent bundles = source.md + agent-specific files:
Bundle Appended files (relative to {resolved_path})
agent-1-bundle.md attack-vectors/attack-vectors.md + hacking-agents/vector-scan-agent.md + hacking-agents/shared-rules.md
agent-2-bundle.md hacking-agents/math-precision-agent.md + hacking-agents/shared-rules.md
agent-3-bundle.md hacking-agents/access-control-agent.md + hacking-agents/shared-rules.md
agent-4-bundle.md hacking-agents/economic-security-agent.md + hacking-agents/shared-rules.md
agent-5-bundle.md hacking-agents/execution-trace-agent.md + hacking-agents/shared-rules.md
agent-6-bundle.md hacking-agents/invariant-agent.md + hacking-agents/shared-rules.md

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

solidity-auditor is a skill published in the GitHub repository mishoko/solidity-auditor-pulse (3 stars, last pushed 5mo ago), licensed MIT. It adds 42 tokens to every session and 1,800 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
