What is vivagents CLAUDE.md?

Project instructions for VivAgents, a standalone server that lets VivaDicta apps access Claude Code, Codex CLI, and Gemini CLI over a network.

Use it when changing the HTTP routes, command-line provider integration, configuration, authentication, or build process.

It describes how to build, run, configure, authenticate, and structure the small Node.js and TypeScript server.

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	$0.00478	$0.00478
Opus 5.5	$0.00191	$0.00191
Sonnet 5.5	$0.00096	$0.00096
Haiku 4.5	$0.00048	$0.00048

Security

Grade A, and why

vivagents CLAUDE.md scanned grade A with 1 finding 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.

What it actually says

CLAUDE.md

Project Overview

VivAgents is a standalone HTTP server that wraps CLI AI tools (Claude Code, Codex CLI, Gemini CLI) behind a simple REST API. It's extracted from VivaDicta macOS app's embedded CLI server to run independently on any machine — Mac, Linux VPS, or Docker.

Primary use case: VivaDicta iOS/macOS apps connect to VivAgents over the network for AI text processing, instead of requiring a Mac running VivaDicta.

Build & Run

npm install
npm run build        # tsc → dist/
npm start            # node dist/index.js (starts server)
node dist/index.js check   # Check which CLIs are available
node dist/index.js token   # Show auth token

Architecture

Runtime: Node.js + TypeScript (ESM)
HTTP: Raw node:http (no Express — only 3 routes)
CLI spawning: node:child_process.spawn with timeout
Config: ~/.vivagents/config.json + env vars + CLI args (cascading priority)
Auth: Bearer token stored in ~/.vivagents/token

Key files

src/index.ts — Entry point, CLI arg parsing, commands
src/server.ts — HTTP server, routing, auth
src/config.ts — Config loading cascade
src/providers/ — Claude, Codex, Gemini CLI providers
src/providers/discovery.ts — Binary discovery (PATH, nvm, known locations)
src/routes/ — /health, /models, /enhance handlers
src/utils/ — Process spawning, error detection

API

GET /health — Server status + provider availability
GET /models — Available models per provider
POST /enhance — Process text through a CLI provider

All endpoints require Authorization: Bearer <token> header.

Conventions

API is 100% backward-compatible with VivaDicta macOS ClaudeCLIServer and iOS ClaudeCLIServerClient
No external dependencies beyond TypeScript + @types/node

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.
