parallel-code CLAUDE.md

Project instructions for an Electron desktop application, with a SolidJS and TypeScript user interface and a Node.js backend. They describe the project structure, commands, and coding conventions.

In plain words
What is it for?
They help start development, build the app, run TypeScript checks, find code in the right folders, and follow rules such as strict TypeScript and functional SolidJS components.
Why use it?
They give a coding agent the local rules it needs to make changes that fit the existing application. This avoids guessing how the frontend, backend, communication, and state management are organized.

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

parallel-code CLAUDE.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 yesterday.

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.

What it actually says

Parallel Code

Electron desktop app — SolidJS frontend, Node.js backend. Published for macOS and Linux only (no Windows).

Stack

  • Frontend: SolidJS, TypeScript (strict), Vite
  • Backend: Node.js (Electron, node-pty)
  • Package manager: npm

Commands

  • npm run dev — start Electron app in dev mode
  • npm run build — build production Electron app
  • npm run typecheck — run TypeScript type checking

Project Structure

  • src/ — SolidJS frontend (components, store, IPC, lib)
  • src/lib/ — frontend utilities (IPC wrappers, window management, drag, zoom)
  • electron/ — Electron main process (IPC handlers, preload)
  • electron/ipc/ — backend IPC handlers (pty, git, tasks, persistence)
  • src/store/ — app state management

Conventions

  • Functional components only (SolidJS signals/stores, no classes)
  • Electron IPC for all frontend-backend communication
  • IPC channel names defined in electron/ipc/channels.ts (shared enum)
  • strict: true TypeScript, no any
Changes

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.
