claudit: Skill for Claude Code

.claude/skills/solodit/SKILL.md

solodit is a skill for Claude Code from marchev/claudit. It costs 33 tokens per session (807 once invoked), scanned A, original, MIT.

A search tool for Solodit, a database of smart-contract security findings from real audits. It finds similar vulnerabilities and provides details about individual findings.

In plain words
What is it for?
Use it during smart-contract reviews to investigate known vulnerability patterns, compare audit findings, and research prior examples.
Why use it?
It helps compare a suspected issue with previously reported security problems instead of researching patterns from scratch.

This is marchev/claudit's own configuration. It tells Claude Code how to work on claudit itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything claudit configures →

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

solodit scanned grade A with 0 findings 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 1mo 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

The opening of the file, as written. The whole thing — 99 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You have access to Solodit's database of 20k+ smart contract security findings via MCP tools. Use them to find prior art, research vulnerability patterns, and compare against known issues from real audits.

Available Tools

mcp__solodit__search_findings

Primary search. Supports keywords, severity, firms, tags, language, protocol, time period, sorting, and advanced filters.

mcp__solodit__get_finding

Get full details for a specific finding by Solodit URL or slug.

mcp__solodit__get_filter_options

Discover valid filter values (firms, tags, categories, languages). Call this first if unsure what values to use.

When to Use

  • Reviewing a vulnerability: Search for similar findings to check if it's a known pattern
  • Auditing a protocol: Search by protocol category, language, or tags relevant to the codebase
  • Researching a bug class: Search by tags (e.g., "Reentrancy", "Oracle") to find real examples
  • Checking prior art: Before reporting a finding, search for similar issues to reference
  • Studying an auditor: Use advanced_filters.user to find a specific researcher's findings

Usage Patterns

Find similar issues

search_findings(keywords="oracle price manipulation", severity=["HIGH", "MEDIUM"], sort_by="Quality")

Research by firm

search_findings(firms=["Sherlock"], severity=["HIGH"], reported="90")

Explore a vulnerability tag

search_findings(tags=["Reentrancy", "Flash Loan"], severity=["HIGH"], sort_by="Quality")

Protocol-specific research

search_findings(protocol="Uniswap", severity=["HIGH", "MEDIUM"])

Language-specific search

search_findings(keywords="reentrancy", language="Solidity", sort_by="Quality")

High-quality solo findings (likely novel)

search_findings(
  tags=["Oracle"],
  advanced_filters={ quality_score: 4, max_finders: 1 }
)

Auditor research

search_findings(advanced_filters={ user: "0x52" }, severity=["HIGH"])

What this file has done since we first saw it

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.

solodit is a skill published in the GitHub repository marchev/claudit (158 stars, last pushed 6mo ago), licensed MIT. It adds 33 tokens to every session and 807 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
