claude-perm-sim

Claude Code permission rule simulator: shows which rule decides a tool call and where a rule set is permissive.

TypeScript · MIT · latest v0.1.0

What it is

claude-perm-sim loads your merged Claude Code permission settings, tells you which rule decides any given tool call, and finds the bypasses: commands that slip past a Bash pattern, paths that escape an Edit scope, and MCP tools nothing covers.

Install

npx @basitalisandhu/claude-perm-sim load                 # run without installing
npm install -g @basitalisandhu/claude-perm-sim@0.1.0     # or install the claude-perm-sim command
