Blocks dangerous commands before execution via a Rust-based Claude Code hook. Use when configuring agent safety guards, setting up destructive command blocking, or auditing CLI protection rules. Use for git reset protection, rm -rf interception, force-push blocking, pack-based command filtering, and PreToolUse hook safety.

A high-performance Claude Code hook that intercepts and blocks destructive commands before they execute. Written in Rust with SIMD-accelerated filtering via the memchr crate and Aho-Corasick multi-pattern matching for sub-millisecond latency. Assumes agents are well-intentioned but fallible.
DCG uses a whitelist-first architecture: safe patterns are checked before destructive patterns, and unrecognized commands are allowed by default (fail-safe). This ensures legitimate workflows are never broken while known dangerous patterns are always blocked. DCG runs as a PreToolUse hook in Claude Code, receiving JSON on stdin for each Bash tool invocation and returning exit code 0 (allow) or 2 (block). It only i...
The processing pipeline has four stages: JSON parsing, command normalization (strips absolute paths like /usr/bin/git), SIMD quick-reject filter (skips regex for commands without git or rm), and pattern matching. The memchr crate provides hardware-accelerated substring search (SSE2/AVX2 on x8664, NEON on ARM), while Aho-Corasick handles multi-pattern matching in O(n) time regardless of pattern count.
