File Based Safety Boundary Enforcement File Guard Hook

via “file-based safety boundary enforcement (file-guard hook)”

Autonomous agent framework with structured memory, safety hooks, and loop management. Built by the agent that runs on it.

Unique: Implements filesystem-level safety boundaries through portable shell scripts that pattern-match file paths against configurable allowlists/blocklists, executing as PreToolUse interceptors to provide deterministic file access control without kernel-level privileges

vs others: Provides granular file-level protection where OS-level permissions (chmod, SELinux) require system administration; unlike application-level checks in Claude Code itself, file-guard is external and cannot be bypassed by prompt injection
