What is 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.

Use them when developing, testing, type-checking, formatting, or preparing changes for the code-by-wire application.

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.

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	$0.01153	$0.01153
Opus 5.5	$0.00461	$0.00461
Sonnet 5.5	$0.00231	$0.00231
Haiku 4.5	$0.00115	$0.00115

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 14d 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.

The opening of the file, as written. The whole thing — 57 lines — stays where its author put it; the contents beside it link to each section on GitHub.

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:native — better-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 + Cloudflare Workers, served at cbw.liyu.dev) 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.

It deploys as an assets-only Worker (website/wrangler.jsonc, no adapter) via Workers Builds on push to main, with preview builds on other branches. The build reads the repo-root CHANGELOG.md (src/pages/changelog.astro), so it needs the whole repo checked out, not just website/.

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.
