What is agentzt CLAUDE.md?

Repository instructions for agentzt, a security proxy that controls how AI agents connect to company models and tools.

Understanding the client and gateway structure, preserving the no-dependency setup, and developing or testing this Node and TypeScript project safely.

They explain how the proxy authenticates agents, limits access, checks requests, and records activity, while setting strict rules for changing the code.

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	$0.01360	$0.01360
Opus 5.5	$0.00544	$0.00544
Sonnet 5.5	$0.00272	$0.00272
Haiku 4.5	$0.00136	$0.00136

Security

Grade C, and why

agentzt CLAUDE.md scanned grade C 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 1mo 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.

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

Guidance for Claude Code (and other agents) working in this repository.

What this is

agentzt — Zero Trust for AI Agents. An AI agent reaches enterprise model APIs and tools only through a zero-trust proxy, the same way a human reaches enterprise apps through a ZTNA client + gateway. It does not replace ZTNA for humans; it secures the agent→model and agent→tool path.

agentzt-client (src/client) — local proxy + per-agent identity. The agent points its model SDK at it (ANTHROPIC_BASE_URL=http://localhost:8787); the client attaches a short-lived token to every request and forwards to the gateway.
agentzt-gateway (src/gateway) — PDP+PEP. Authenticates the agent, issues scoped short-lived tokens, enforces deny-by-default RBAC + ABAC + JIT, runs input/output guardrails, audits everything, then forwards to the real model API / tools.

Hard constraints — read before editing

Zero runtime dependencies. No build step. Everything runs on Node ≥ 22.6 via native TypeScript type-stripping (node src/...ts). Do not add npm dependencies or a bundler. package.json deps stay empty (only @types/node + typescript as devDeps for editor/typecheck).
Because of type-stripping, write erasable TypeScript only: no enum, no namespace, no constructor parameter properties, no decorators. Use import type for type-only imports and .ts extensions on every relative import (ESM).
The only allowed external process is openssl, and only in src/cli/tls.ts for opt-in mTLS PKI setup. The runtime never shells out.
Use Node built-ins only: node:http, node:https, node:crypto, node:tls, global fetch. Note global fetch can't carry client certs — use src/client/transport.ts (which falls back to node:https) for outbound client calls.

Commands

npm run demo        # end-to-end: enroll, start gateway+client, drive 8 control checks, audit
npm run demo:mtls   # same, over mutual TLS (needs openssl)
npm test            # 28 checks (auth, RBAC, guardrails, ABAC, JIT, audit chain, mTLS)
npm run typecheck   # tsc --noEmit (needs `npm i` once for typescript)

npm run gateway                                  # start gateway (PDP+PEP)

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.
