mudguard
Aijo24/mudguard
mudguard is an autonomous, delta-aware architecture analysis skill for Claude Code that sweeps codebases for deep-module and deletion-test opportunities, independently verifying candidates before filing them as vertical-slice issues.

GreatOverview
Designed to prevent architectural silt, mudguard operates headlessly to evaluate codebases—either entirely or in specific subsystems—using an inlined methodology derived from modern codebase design principles. It employs a rigorous propose-and-verify split, maintains delta-awareness to avoid re-analyzing unchanged components, and leverages per-area receipts to store exclusion maps and rejection history. The skill runs safely within an isolated git worktree without executing external scripts by default, producing ready-to-grab vertical-slice tickets under a scratch directory.
Capabilities
- ▸Autonomous codebase architecture sweeping

Security considerations
The skill performs analysis-only operations and writes exclusively to local scratch directories. It executes inside an isolated git worktree on a dedicated branch, avoids pushing changes by default, and downloads or fetches no external data or scripts during standard execution.
