Keep Claude Code concise, clean, and under control.

Compact professional output, context hygiene, tool-output filtering, and usage telemetry for Claude Code Max users.

Governor is the serious alternative to style-only token savers. It keeps the agent concise, shrinks recurring memory files, blocks noisy logs from flooding context, and adds planning guardrails for broad tasks.

The installed Claude Code command namespace is still /governor:*.

Restart Claude Code, then run:

/governor:status
/governor:audit
/governor:compress CLAUDE.md

Governor auto-starts in compact professional mode when the plugin is loaded. Use /governor:off to disable response compression and /governor:on to re-enable it.

Heavy Claude Code users do not only burn quota on long answers. The bigger session killers are often:

• bloated always-loaded context such as CLAUDE.md, notes, and rules
• huge Bash/test/build output copied into conversation context
• vague prompts that trigger broad scans and repeated failed attempts
• scope drift during long coding tasks
• compactions caused by preventable context growth

Governor attacks those system problems while keeping the interaction professional and readable.

Small local smoke benchmarks, not universal claims. Same machine, same prompt set, Claude CLI non-interactive runs.

Three technical explanation prompts, Sonnet, no tools.

Synthetic noisy pytest -vv output with preserved failure lines.

Interpretation: Caveman is excellent at style compression. Governor aims for broader quota control: compact output, recurring-context compression, noisy-tool filtering, telemetry, and retry reduction.

• Always-on compact mode: SessionStart and UserPromptSubmit hooks keep responses concise in every Claude Code chat.
• Professional memory compression: /governor:compress CLAUDE.md rewrites verbose memory files into dense prose.
• Protected-span safety: code blocks, inline code, paths, URLs, commands, env vars, versions, headings, tables, and warnings are preserved.
• Quality guard: low-savings compression is rejected and the backup is restored instead of pretending success.
• Tool-output filtering: noisy Bash/test/build output is summarized while preserving failure signals.
• Telemetry ledger: /governor:status reports blocked tokens, failures, compactions, and statusline snapshots when available.
• Prompt guidance: vague broad prompts get soft, non-blocking suggestions.
• Plan and drift guard: explicit contracts for broad builds, then scope checks with /governor:guard.
• Portable rule snippets: compact-mode rules for Codex, Gemini, Cursor, Windsurf, and Cline.

gh repo clone 0xhimanshu/governor
cd governor
bash install.sh --force

bash install.sh --project /path/to/project --agents all

Supported rule snippets:

Other agents get compact professional behavior only. Claude Code is the V1 target for hooks, telemetry, statusline, and Bash output filtering.

/governor:compress is automatic from the user's point of view:

1. Create a timestamped backup.
2. Mark protected spans.
3. Rewrite the file with dense professional prose.
4. Strip markers.
5. Validate protected content.
6. Attempt protected-span recovery if needed.
7. Reject low-savings output and restore the backup if the quality guard fails.
8. Report exact before/after token estimates and backup location.

Compression levels:

Set GOVERNOR_ALLOW_LOW_SAVINGS=1 only if you intentionally want to keep a low-savings compression result.

Governor stores a local JSONL ledger under:

~/.claude/plugins/governor/

It tracks:

• tool-output tokens blocked
• full-output overrides
• prompt-risk suggestions
• Bash failures
• compactions
• statusline snapshots
• memory compression savings

Prompt caching can reduce usage/cost but does not necessarily reduce context window occupancy. Governor reports those separately when Claude Code exposes the data.

Use benchmarks/ for measured comparisons.

Recommended conditions:

• control: no token/style plugin
• caveman: Caveman enabled as normal
• governor-hooks: Governor hooks enabled, memory unchanged
• governor-compressed: Governor after /governor:compress CLAUDE.md
• governor-strict: optional strict-mode run for broad tasks

Fill benchmarks/run-sheet.csv, then run:

python3 scripts/compare_benchmarks.py benchmarks/run-sheet.csv

Primary metrics: five-hour usage delta, peak context %, assistant output tokens, tool-output tokens blocked, failed tool calls, compactions, wall time, and task success.

• Helpful by default, strict only when invoked.
• Professional dense prose, never novelty dialect.
• Measure exact savings where possible.
• Treat 1M context as a ceiling, not a target.
• Keep broad planning and drift checks opt-in.
• Restore backups instead of accepting unsafe or low-value compression.

• If hooks do not fire, /governor:status will show little or no telemetry.
• Existing custom statuslines are not overwritten by the installer.
• Compression sends file content through the active Claude Code/model workflow. Do not compress secrets or sensitive private files.
• Use /governor:full before a diagnostic command when you need unfiltered logs.
• For installed-but-inactive behavior, launch Claude Code with GOVERNOR_DEFAULT_MODE=off.
