agent-readiness-manifest

· Spec site · strattlabs.com

An open, declaration-only spec and reference validator for the Agent Readiness Manifest — a single well-known descriptor that points to a site’s agent-relevant resources and states its self-declared posture toward automated agents.

Think robots.txt, but for agent discovery: one small JSON file that says “here is everything I declare about how to work with me” and points at your existing llms.txt, MCP descriptor, agent card, OpenAPI doc, policies, and more.

• 📄 SPEC.md — the specification.
• 🧱 schema/agent-readiness.schema.json — the normative JSON Schema (draft 2020-12).
• ✅ Reference validator — a small CLI + library that checks a manifest against the schema.

Status: v0.1 draft / request-for-comment. The schema is the normative contract; expect additive change before 1.0.

The manifest is a set of pointers and self-declared posture, and the reference validator is structural only: it tells you a manifest is well-formed against the schema.

Install

pnpm add @strattlabs/agent-readiness-manifest
# or: npm i @strattlabs/agent-readiness-manifest

Requires Node.js ≥ 18.18.

CLI

agent-readiness validate ./.well-known/agent-readiness.json

Exit code 0 when the manifest is structurally valid, 1 when invalid, 2 on a usage error — suitable for CI.

$ agent-readiness validate examples/invalid.json
  /version: must match pattern "^\d+\.\d+$"
  /site: must have required property 'url'
  /resources/llmsTxt: must match pattern "^(https?://|/).+"
  (root): unexpected property "unknownField"
  /policy/agentsAllowed: must be boolean
✗ examples/invalid.json: 5 error(s)

The schema declares a fixed vocabulary (additionalProperties: false), so any property it does not define is reported as an error.

Library

import { validateManifest, type AgentReadinessManifest } from '@strattlabs/agent-readiness-manifest';

const manifest: AgentReadinessManifest = {
  version: '0.1',
  site: { name: 'Acme', url: 'https://acme.example.com' },
  resources: { llmsTxt: '/llms.txt', mcp: '/.well-known/mcp.json' },
  policy: { agentsAllowed: true },
};

const result = validateManifest(manifest);
if (!result.valid) {
  for (const e of result.errors) console.error(`${e.path}: ${e.message}`);
}

The JSON Schema is also importable for use in your own tooling:

import { loadSchema } from '@strattlabs/agent-readiness-manifest';
// or reference the file directly:
import schema from 'agent-readiness-manifest/schema' with { type: 'json' };

Minimal manifest

{
  "$schema": "https://strattlabs.github.io/agent-readiness-manifest/schema/agent-readiness.schema.json",
  "version": "0.1",
  "site": { "url": "https://acme.example.com" }
}

See examples/ for minimal, complete, and intentionally-invalid samples.
