limboo: Instructions file for Claude Code

CLAUDE.md

limboo CLAUDE.md is an instructions file for Claude Code from limboo-ai/limboo. It costs 25,202 tokens per session, scanned A, original, MIT.

A project instruction file for Limboo, a local-first desktop app that provides the workspace around an AI coding agent.

In plain words
What is it for?
Use it when developing Limboo, navigating its three Electron contexts, or checking how sessions and project services are organized.
Why use it?
It explains the project’s architecture and rules so an agent can work safely across sessions, repositories, terminals, memory, permissions, and interface code.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md. Also seen: mentions CLAUDE.md; mentions subagents; names the ExitPlanMode tool.

This is limboo-ai/limboo's own configuration. It tells Claude Code how to work on limboo itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything limboo configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

limboo CLAUDE.md scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

How it starts

The opening of the file, as written. The whole thing — 1,520 lines — stays where its author put it; the contents beside it link to each section on GitHub.

CLAUDE.md

Operational guide and deep context for any AI coding agent (Claude, etc.) working in this repository. Read this first. It explains what Limboo is, how the code is organized, the rules you must follow, and what is and is not built yet.

Companion document: project.md holds the full product/architecture vision. CLAUDE.md (this file) is the practical, code-level contract for working in the repo. When the two disagree about current reality, trust CLAUDE.md.


1. What is Limboo?

Limboo is a local-first desktop application that acts as the operating system for AI software development. It is not an AI model. Instead, it provides the environment around a connected coding agent: project management, sessions, file watching, repository indexing, git operations, terminal execution, memory, permissions, context, search, and UI.

Core idea: every development task happens inside a Session. A session bundles a repository, branch, chat history, agent, terminal history, checkpoints, permissions, context, memory, tasks, and generated files into one workspace.

Guiding principles (from project.md §4): Fast, Local, Private, Modular, Secure, Responsive, Observable, Predictable, Recoverable. There is no backend. Limboo itself makes exactly three kinds of outbound request, and no others may be added without amending this paragraph:

  1. The connected coding agent talking to its AI provider.
  2. Contributor avatars — so commit history can show a real face. Two steps, both gated by the single settings.git.avatars.enabled switch:
    • Identity. A GitHub noreply commit address already encodes the account (<id>+<login>@users.noreply.github.com), so it needs no lookup. Every other address — which is most real history — can only be resolved by GitHub, so GhManager.commitAuthors calls one read-only endpoint, GET /repos/{owner}/{repo}/commits, through the gh CLI. It returns commit.author.email alongside the resolved author.{login,avatar_url}, mapping a whole page of history per request. This tells GitHub which repository is being browsed — the reason the setting exists and says so.
    • Image. main/managers/gh/avatars.ts fetches the picture from GitHub's avatar host: host-allowlisted, https-only, manual redirect screening, byte- and time-capped, magic-byte sniffed (no SVG), and screened by isEmbeddedAvatar before it can reach an <img src>.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
