In development · macOS 14+

Organize the rules
you give Claude Code.

A native Mac app we are building for the CLAUDE.md and settings.json files Claude Code reads. It will move rules between user, project, and local, and edit settings without making you remember schemas. Rulebook is in development and not available yet.

Rules

Move rules between user, project, and local.

Rulebook parses each CLAUDE.md by double-newline blocks. Drag a rule into another level and the source and destination files update atomically. Full undo, search, and inline Markdown highlighting.

Settings

Every settings.json field, in one place.

All ~80 documented settings (permissions, sandbox, hooks, MCP, plugins, attribution) with inline tooltips sourced from the Claude Code docs. The Permissions editor groups your rules by tool and offers one-click consolidation when 12 git rules can become Bash(git:*).

Enhance

Rewrite rules with Claude. Iterate on the result.

Click Enhance and Rulebook shells out to claude -p, then shows a side-by-side diff. Not quite right? Type feedback and it continues the same conversation via --resume. The session ID is rulebook-<short-id> so you can find it in /resume too.

FAQ

Questions, answered.

Can I get Rulebook now?+

Not yet. Rulebook is in development and not available yet. Email hello@greatwork.company if you want to hear when it launches.

Does Rulebook need Claude Code installed?+

Mostly no. It reads and writes the same CLAUDE.md and settings.json files Claude Code does, but it doesn't run Claude Code at runtime. The exception is the Enhance button, which shells out to the claude CLI on your PATH.

Which files does it touch?+

~/.claude/CLAUDE.md, ~/.claude/settings.json, ~/.claude/settings.local.json, plus any project's .claude/CLAUDE.md or ./CLAUDE.md, .claude/settings.json, .claude/settings.local.json, CLAUDE.local.md, and .mcp.json. Managed enterprise config at /Library/Application Support/ClaudeCode/ is shown read-only.

Will it clobber my existing files?+

No. Rules are split on double-newlines on read and joined back on write. Settings.json round-trips through a Codable model with an overflow dictionary that preserves any unknown fields. All writes are atomic.

How does Enhance work, exactly?+

It runs claude -p --session-id <uuid> with your rule. If you give feedback, it runs claude --resume <uuid> with the follow-up, so Claude remembers the previous attempt and can refine. Sessions are named rulebook-<short-id> for visibility in /resume.

Is it open source?+

No. Pricing will be announced when Rulebook launches.

Does it sync between machines?+

No, because CLAUDE.md and settings.json sync on their own if you keep ~/.claude/ in dotfiles or your project config in git. Rulebook edits the source of truth.

Apple Silicon?+

It is being built to run natively on both Apple Silicon and Intel Macs.
