code-by-wire CLAUDE.md

Project instructions for code-by-wire, an application built with Electron, React, and TypeScript. They describe development commands, testing, formatting, native-module rebuilding, cross-platform requirements, and code organization.

In plain words
What is it for?
Use them when developing, testing, type-checking, formatting, or preparing changes for the code-by-wire application.
Why use it?
They give a coding agent the repository’s expected tools and checks, reducing mistakes such as using the wrong package manager or skipping required builds.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

code-by-wire 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 2d 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.

CLAUDE.md

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

Development

  • Package manager is pnpm (pinned), Node 24. Use pnpm, never npm.
  • pnpm dev runs the app (electron-vite). pnpm test runs the suite (vitest); tests live in tests/ mirroring the source tree. tests/renderer/** and tests/xterm/** run under jsdom (renderer logic only); there's no component-render harness, so verify actual UI by hand. Vitest only picks up tests/**/*.test.ts — no .tsx tests.
  • CI runs pnpm test on both ubuntu-latest and windows-latest (.github/workflows/ci.yml) — terminal/pty and path-handling code must work on both, not just macOS where local dev happens.
  • After pnpm install or any Electron upgrade, run pnpm rebuild:nativebetter-sqlite3 and node-pty are native modules and must be rebuilt against Electron's ABI, or the app crashes on launch.
  • pnpm typecheck runs two passes: tsconfig.node.json (main/preload/shared/tests) and tsconfig.web.json (React renderer, JSX). Test-reachable types must live in JSX-free .ts so they pass under the node config.
  • Before pushing, run pnpm format and pnpm lint — CI's lint job runs format:check then lint and fails on either.
  • scripts/make-icon.mjs (pnpm icon) string-replaces exact lines from build/icon.svg — editing the SVG can silently break macOS icon generation; check the script's .replace() targets after any SVG change.

Website

website/ (marketing site, Astro + Vercel) is a separate project sharing this repo — it has its own pnpm-workspace.yaml, isolating its install and lockfile from the root workspace. Run its commands from inside website/: pnpm install, pnpm dev, pnpm run check (typecheck), pnpm test.

Architecture

Electron app, three processes plus a utility process:

  • main (src/main/) — Node. Reads Claude Code and Codex transcripts (provider/claude/, provider/codex/), analytics in better-sqlite3 (db/), pty terminals (terminal/), git, settings. Request/response only — no background timers or fs.watch; the renderer polls.
  • parse worker (src/main/parse-worker/, its own bundle entry → out/main/parse-worker.js) — a utilityProcess main forks lazily so every poll-driven fs read (summarize, discovery, transcript/metrics/shells/monitors/tasks reads, the reconcile sweeps) runs off the main thread. It hosts the same ClaudeReader main falls back to; transcript docs return as one JSON string (TranscriptReadWire) that main relays and the preload parses. Still request/response (rides renderer polls); on worker fault each read degrades to the same code in-process. Main-process state (managed registry, model picks) never moves in — it rides the request or adorns the response.
  • preload (src/preload/) — contextBridge exposing window.api to the renderer.
  • renderer (src/renderer/src/) — React 19 + Tailwind 4 + xterm.

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.

code-by-wire CLAUDE.md is an instructions file published in the GitHub repository luojiahai/code-by-wire (74 stars, last pushed 6d ago), licensed MIT. It adds 1,073 tokens to every session, about $0.0054 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
