Default deterministic codec + opt-in own-trained ML sidecar (no API key, no vendor). Ships a skill, UserPromptSubmit + PreCompact + PostToolUse hooks, lossless tool-result codec (ANSI strip + JSON minify + blank-collapse + trailing marker + data-shape guard + schema-tag prefix + break-even guard), and a 4-arm token benchmark. Fail-open on every path. Run bench/bench.py for measured numbers.","version":"0.5.0","strict":true,"keywords":["token-compression","codec","deduplication","compaction","hook","mcp","observability","context-window","claude-code"],"category":"deployment"}]}
