l0-compressorCLI proxy for LLM token savings

Reduce AI coding assistant token consumption by 50-80% with a single command prefix.

l0-compressor --stats telemetry dashboard

Universal Filtering

Works with any command. No per-tool parsers and no alias rewriting -- just prefix with l0-compressor, or enable the optional Claude Code / Gemini CLI hook.

Adaptive Auto-tuning

Six rules adjust head/tail budgets per command from execution history, and persist what they learn between runs.

Safety Guard

Refuses rm -rf on system paths and HOME, reverse shells, credential exfiltration, DROP DATABASE. 161-case adversarial test suite.

Zero Overhead

Single-threaded, synchronous Rust binary. Sub-millisecond overhead. 700 KB on disk.

Production Hardened

UTF-8 lossy reads, OOM protection, SIGPIPE handling, POSIX exit codes, metrics rotation, telemetry redaction.

Cross-Platform

macOS, Ubuntu, Alpine, LXC, Proxmox, VPS. Static musl build for containers.
