What is orbit CLAUDE.md?

Project instructions for Orbit, a real-time task manager with features such as documents, files, notifications, GitHub integration, and an MCP server. They define the project’s tooling, code rules, validation requirements, and writing constraints.

Use them when developing or reviewing Orbit code, running its checks, handling external input, or preparing project documentation and commits.

They keep contributions consistent with the project’s required runtime, strict typing, input validation, and style rules. They also prevent prohibited references and unsupported implementation choices.

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.

Model	Per session	Once invoked
Fable 5.1	$0.03986	$0.03986
Opus 5.5	$0.01594	$0.01594
Sonnet 5.5	$0.00797	$0.00797
Haiku 4.5	$0.00399	$0.00399

Security

Grade A, and why

orbit 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 1mo 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.

Expected in a hook, worth knowing in a rule or an instructions file.

How it starts

The opening of the file, as written. The whole thing — 219 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Orbit

Free, realtime, keyboard-first task manager. The UX polish of the best paid task managers with the breadth of the open-source ones, plus docs, files, notifications, GitHub, and an MCP server. No pricing, no billing, no paid tiers anywhere.

Hard rules

Bun is the package manager and the script runner. There is no pnpm, no npm, no yarn, no Turbo, and no node_modules produced by anything but bun install. Every command in this file starts with bun. The deployed runtime is node, so shipped code must not import a Bun built-in.
No comments in code. Ever. bun run check-comments fails the build on any comment that is not a functional directive (@ts-*, biome-ignore, eslint-*, /*! license */). Make names and structure carry meaning.
No AI attribution. Never mention Claude, Anthropic, Codex, or AI tooling in commits, branches, PRs, code, or docs.
No em-dash characters in code, copy, docs, or commit messages. Use commas, colons, or separate sentences.
Strict types only. any is a lint error. Non-null assertions are a lint error. noUncheckedIndexedAccess and exactOptionalPropertyTypes are on. Validate every external input with Zod.
Every check green before you finish. bun run verify runs lint, comment policy, typecheck, and tests.

Bun is the toolchain, not the runtime

Bun installs, runs scripts, and runs tests. Shipped server code must not call a Bun built-in, because the web app runs on Vercel's node runtime: that is the only runtime where a Vercel function can upgrade a websocket, and /api/ws needs it. Anything imported from bun fails there with Cannot find module 'bun'.

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.
