Show HN: Whole Body Compute: A local 5-organ runtime for coding agents on Mac Whole Body Compute released `body`, a local macOS runtime that intercepts coding-agent file reads and tool outputs in under 3ms before they reach cloud billing, claiming up to 98.7% token reduction on large reads and 96.9%–99.5% sensory token reduction on desktop vision. Across 146 live unscripted agent sessions, including 100 official princeton-nlp/SWE-bench_Verified runs across 10 Python organizations, the project reports 30/30 (100% Pass@1) and 10/10 Pass^3 with context falling from 203.08M to 137.23M tokens, which it describes as zero accuracy loss. The tool auto-wires PreToolUse/PostToolUse hooks for Claude Code, Cursor, Windsurf, Cline, Goose and Antigravity, and adds a 23-vendor secret redaction layer claiming 0 secret leaks and 0.0% ASR on AgentDojo. Cut agent token burn and latency with zero accuracy loss on SWE-bench Verified. Whole Body Compute makes AI computing simpler, faster, and local: giving Claude Code, Cursor, Windsurf, Cline, Goose, and Antigravity a <3ms AST context shield, native macOS vision, and on-device memory right on your Mac with cross-platform Blood-Brain Barrier & FinOps audit support on Linux . Option 1: 1-line installer macOS & Linux curl -fsSL https://wholebodycompute.com/begin | sh Option 2: uv / pipx directly from GitHub uv tool install git+https://github.com/wholebodycompute/whole-body-compute.git && body begin Option 3: Source checkout git clone https://github.com/wholebodycompute/whole-body-compute.git cd whole-body-compute python3 -m venv .venv && source .venv/bin/activate && pip install -e . body begin Or run a read-only 30-day token spend audit across your local agent logs with zero installation: curl -sSL https://wholebodycompute.com/audit.py | python3 Cloud coding agents burn massive context windows re-ingesting full files, noisy test logs, and screenshots on every turn. Whole Body Compute body sits locally between your coding agent and macOS/Linux hardware, intercepting bloated reads and tool outputs in <3ms before they hit your cloud billing meter. ┌────────────────────────────────────────────────────────────────────────────────────────┐ │ WHOLE BODY COMPUTE 5 CORE ORGANS │ ├──────────────────────────┬──────────────────────────┬──────────────────────────────────┤ │ 01.
