What Cosmos Vulnerability Scanner does

Cosmos Vulnerability Scanner scans Cosmos SDK blockchain modules and CosmWasm contracts for consensus-critical vulnerabilities such as chain halts, fund loss, and state divergence. Use it when auditing custom x/ modules, reviewing IBC integrations, or assessing pre-launch chain security.

Cosmos Vulnerability Scanner is cataloged under Quality on DirSkills. Cosmos Vulnerability Scanner comes from a repository tagged agent-skills.

Documentation

README

Cosmos Vulnerability Scanner

Purpose

Scan Cosmos SDK modules and CosmWasm contracts for vulnerabilities that cause chain halts, consensus failures, or fund loss. Spawns parallel scanning agents — each specializing in a vulnerability category — that return findings to the main skill, which then writes them as individual markdown files to an output directory.

Output directory: defaults to .bughunt_cosmos/. If the user specifies a different directory in their prompt, use that instead.

When to Use

  • Auditing Cosmos SDK modules (custom x/ modules)
  • Reviewing CosmWasm smart contracts
  • Pre-launch security assessment of Cosmos chains
  • Investigating chain halt incidents

When NOT to Use

This is the opening of the README. Read the full README on GitHub.
