What is open-claude-cowork AGENTS.md?

Repository instructions for Open Claude Cowork, an Electron, React, and TypeScript desktop application for working with AI agents.

Installing dependencies, running development processes, linting source files, and building the application for macOS, Windows, or Linux.

They explain the code layout, development commands, naming rules, and testing expectations before an agent edits the project.

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	$0.00614	$0.00614
Opus 5	$0.00307	$0.00307
Sonnet 5	$0.00123	$0.00123
Haiku 4.5	$0.00061	$0.00061

Security

Grade A, and why

open-claude-cowork AGENTS.md scanned grade A with 0 findings 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 10d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Repository Guidelines

Project Structure & Module Organization

This is an Electron + React + TypeScript desktop app.

src/main/: Electron “main” process (ACP client, SQLite, IPC, filesystem/runtime helpers).
src/render/: React “renderer” UI (components, hooks, state, agent presets/icons).
src/types/: Shared TypeScript types.
builder/: Rsbuild configs for main and render.
public/ and assets/: Static assets (icons/wallpapers, etc.).
env/: Build/runtime env templates (per-platform .env.*).

Notes:

release/ is generated output and is git-ignored (see .gitignore).

Build, Test, and Development Commands

Use pnpm (see package.json#packageManager).

pnpm install: Install deps (runs Electron postinstall + native deps setup).
pnpm run dev: Local dev (uses plop to orchestrate main + renderer).
pnpm run dev:render: Start only the renderer dev server.
pnpm run dev:main: Start only the main process (via nodemon.json).
pnpm run lint: Run Biome checks + auto-fix for src/.
pnpm run build: Production build (interactive platform selection).
pnpm run build:darwin|build:win32|build:linux: Platform-specific builds.
pnpm run rebuild:main: Build main process and launch Electron using release/dist/main/index.js.

Coding Style & Naming Conventions

Indentation: 2 spaces, line width 100 (Biome: biome.json).
Quotes: double quotes (Biome JS/TS formatter).
TypeScript: strict: true (tsconfig.json), prefer explicit types at boundaries.
Paths: use aliases where appropriate (@main/*, @render/*, @components/*, etc.).

Testing Guidelines

There is no repository-level test runner wired (no test script/config). Changes should include a quick manual check:

Run pnpm run dev and exercise the relevant UI/IPC/agent flow.
For build-related changes, verify with a platform build script (e.g. pnpm run build:darwin).

Commit & Pull Request Guidelines

Commits generally follow Conventional Commits style (examples in history): feat:, fix:, refactor:, chore:, style:, release:.

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.
