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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.25202 | $0.25202 |
| Opus 5 | $0.12601 | $0.12601 |
| Sonnet 5 | $0.05040 | $0.05040 |
| Haiku 4.5 | $0.02520 | $0.02520 |
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.

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.mdholds 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, trustCLAUDE.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:
- The connected coding agent talking to its AI provider.
- Contributor avatars — so commit history can show a real face. Two steps,
both gated by the single
settings.git.avatars.enabledswitch:- 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, soGhManager.commitAuthorscalls one read-only endpoint,GET /repos/{owner}/{repo}/commits, through theghCLI. It returnscommit.author.emailalongside the resolvedauthor.{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.tsfetches 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 byisEmbeddedAvatarbefore 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.

limboo CLAUDE.md is an instructions file published in the GitHub repository limboo-ai/limboo (92 stars, last pushed yesterday), licensed MIT. It adds 25,202 tokens to every session, about $0.1260 per session on Opus 5. A static security scan graded it A with 1 finding (runs shell commands). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
