dudoxx-ai-terminal: Instructions file for Claude Code

CLAUDE.md

dudoxx-ai-terminal CLAUDE.md is an instructions file for Claude Code from Dudoxx/dudoxx-ai-terminal. It costs 1,002 tokens per session, scanned A, original, MIT.

A root CLAUDE.md instruction document for a multi-package project that shares terminal sessions between people and coding agents. It describes the repository's purpose, packages, technologies, ports, and verification rules.

In plain words
What is it for?
It is for guiding work across the terminal contract library, NestJS broker, MCP agent channel, Next.js web interface, and end-to-end command-line fixtures.
Why use it?
It gives an agent project-specific rules and structure, reducing confusion about which package owns a change and how to check the result.

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

dudoxx-ai-terminal 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 2mo 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.

dudoxx-ai-terminal — CLAUDE.md (root DOX contract)

Binding work contract for this repo. Per-package CLAUDE.md files (closer-wins for local detail) live in each workspace package and are the authority for that package. This root doc carries repo-wide rules only. See the cascade index at the bottom.

Purpose

Shared multi-terminal bridge — one pinned tmux session is the canonical shared state; a human (web/xterm.js) and an AI agent (MCP) attach to the same terminals simultaneously. Four workspace packages + two CLI e2e fixtures.

Package Role Port / transport CLAUDE.md
@ddx/term-contract zod schemas: WS frames, MCP tool I/O, descriptors library (ESM+CJS+types) packages/ddx-term-contract/CLAUDE.md
ddx-term-broker human channel + canonical state (NestJS 11) HTTP/WS 13330 ddx-term-broker/CLAUDE.md
@dudoxx/ddx-term-mcp agent channel: MCP stdio, thin tmux client (no PTY) stdio ddx-term-mcp/CLAUDE.md
ddx-term-web xterm.js UI, one tab per terminalId (Next.js 16) HTTP 13340 ddx-term-web/CLAUDE.md

ddx-cli-py / ddx-cli-ts are interactive e2e-target fixtures — NOT workspace packages, never built or published from here.

Repo-wide invariants (the cascade floor — see context/_invariants.md)

  • The MCP server NEVER holds a PTY — it shells out to tmux only (no-pty.spec.ts guards this). A private PTY breaks shared state.
  • terminalId = stable address; pid = transient signal target. Never conflate.
  • All cross-boundary types come from @ddx/term-contract — never redefine a frame or descriptor in broker/mcp/web.
  • Broker pins session size (120×30) and owns canonical dims — no client renegotiation.
  • Zero any across all TypeScript.

Stack

  • Monorepo: pnpm 10.24.0 + turbo 2.5 + changesets. Node >=20.9.
  • TS 5.7 strict everywhere; @ddx/term-contract builds before broker/mcp/web (turbo DAG).
  • Only @dudoxx/ddx-term-mcp is published (public npm). Others are private by design.

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.
