CLAUDE.md

ai-phone-agent CLAUDE.md is an instructions file for Claude Code from bobbylkchao/ai-phone-agent. It costs 676 tokens per session, scanned A, a copy of ai-phone-agent AGENTS.md, MIT.

Repository-specific instructions for coding agents working on a Node.js and TypeScript backend for phone calls using OpenAI Realtime, Twilio, and Amazon Connect.

In plain words
What is it for?

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

ai-phone-agent 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 11d 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.

Origin

This is a copy

100% identical to ai-phone-agent AGENTS.md — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

The opening of the file, as written. The whole thing — 55 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Agent instructions (developers)

AGENTS.md and CLAUDE.md are intentionally the same. Edit both when you change this document so Cursor and Claude Code stay aligned.

What this repo is

  • Node.js + TypeScript backend for real phone callsOpenAI Realtime (voice).
  • Two integrations: Twilio (src/service/twilio-phone/) and Amazon Connect + OpenAI SIP (src/service/amazon-connect-phone/openai-sip-webhook/).
  • Phone-only — no browser voice UI in this kit.

Layout

Area Role
src/foundation/ Shared OpenAI helpers, Twilio WebSocket, MCP servers, Amazon Connect SDK helpers.
src/service/twilio-phone/ Twilio HTTP + wiring into foundation.
src/service/amazon-connect-phone/ Connect: incoming webhook, accept/hangup, Realtime WS, tools, SIP instructions.
doc/ Architecture and integration guides — read before large changes.

Imports use @/*src/*; build uses tsc-alias for dist/.

Conventions

  • Small, focused diffs — match existing style; don’t refactor unrelated code.
  • Lint / format — ESLint uses Airbnb (eslint-config-airbnb-base + @kesills/eslint-config-airbnb-typescript) with Prettier (eslint-config-prettier). Run npm run lint and npm run format before you finish.
  • Tools — New Realtime tools: Zod schema + matching parametersJsonSchema, register in openai-sip-webhook/tools/index.ts (same pattern as existing tools).
  • Voice prompts — Connect SIP: openai-sip-webhook/agents/ (e.g. sip-instructions.ts, entry-agent.ts). Twilio: service/twilio-phone/agents/realtime-phone/.

Security

  • Never commit secrets.env is gitignored; use .env.example for keys names only.
  • Don’t log API keys, tokens, or full PII; sanitize error messages aimed at end users.

npm run dev      # nodemon

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.
