Governor: A Claude Code Plugin to Cut Token Waste via Output Compression, Context Slimming, and Tool Filtering

Governor is a Claude Code plugin that tackles token and context bloat beyond simple style compression. It reduces output tokens, shrinks recurring memory files like CLAUDE.md, filters noisy build/test logs, and adds planning guardrails to prevent scope drift. It's installed as a Claude Code plugin, exposing a /governor:* command namespace.
Quick Start
bash install.sh --forceRestart Claude Code, then run:
/governor:status
/governor:audit
/governor:compress CLAUDE.mdGovernor auto-starts in compact professional mode. Toggle with /governor:on and /governor:off.
Benchmarks
Small local benchmarks with Sonnet (non-interactive, no tools):
- Output tokens (three technical prompts): Control avg 989 tokens → Governor avg 440 tokens (55.5% savings). Caveman-style gives 44.9% savings.
- Memory compression: 1877-token file → 838 tokens (55.4% savings) with medium compression.
- Tool output filtering: Synthetic
pytest -vvnoisy output of 54,314 estimated tokens → 1,726 tokens (96.8% blocked) with preserved failure lines.
Key Features
- Always-on compact mode via
SessionStartandUserPromptSubmithooks. - Professional memory compression:
/governor:compress CLAUDE.mdrewrites verbose files while preserving code blocks, inline code, paths, URLs, headings, tables, warnings, and env vars. A quality guard rejects low-savings compressions and restores the backup. - Tool-output filtering: Summarizes noisy Bash/test/build output but preserves failure signals.
- Telemetry ledger:
/governor:statusreports blocked tokens, failures, compactions. - Prompt guidance: Soft suggestions for vague broad prompts.
- Plan and drift guard:
/governor:plancreates an implementation contract;/governor:guardchecks current changes against it. - Portable rule snippets: Compact-mode rules included for Codex, Gemini, Cursor, Windsurf, and Cline.

Heavy Claude Code users should try Governor if they struggle with context bloating, broad task drift, or noisy logs eating their quota. It's a serious alternative to style-only token savers.
