nyldn/claude-octopus v9.19.0

v9.19.0 — CC v2.1.87-92 sync, token compression, ~7,300 tokens/session savings

on GitHub

Highlights

• 13 new CC feature flags (122 total) — synced through v2.1.91. PostCompact context recovery, --bare subprocess optimization, Elicitation hooks, bin/ plugin executables, MCP result size override, and more.
• Headroom-inspired token compression — bin/octo-compress CLI and automatic PostToolUse hook compress large JSON arrays (80-95%), logs (82-95%), HTML (70-90%), and verbose output (60-80%). HUD "Saved" column tracks savings.
• ~7,300 tokens/session savings — Hook conditional gates, PostToolUse consolidation (3→1 dispatcher), context-reinforcement trim (750→150 tokens), lazy skill paths: on 9 skills, CLAUDE.md diet (36% smaller), additionalContext minimization.
• Plugin CLI — octopus doctor, octopus version, octopus session, octopus fleet as bare commands (CC v2.1.91+).
