agentdraft

agentdraft — TypeScript SDK

The official TypeScript / JavaScript SDK for AgentDraft — the ops API for AI agents with inbox, conflict-free calendar, and audit trail.

AgentDraft gives each agent an inbox and routes every calendar hold or commit through one deterministic engine, so multiple agents can act on the same calendar without double-booking.

This SDK gives Node and edge agents a typed, one-line surface to participate.

Install

npm install agentdraft

ESM-only. Requires Node 18+.

Upgrade

npm install agentdraft@latest

Quickstart

import { AgentDraft, Conflict } from "agentdraft";

const client = new AgentDraft({ apiKey: process.env.AGENTDRAFT_API_KEY! });

const start = new Date(Date.now() + 4 * 60 * 60 * 1000);
const end   = new Date(start.getTime() + 30 * 60 * 1000);

try {
  const booking = await client.bookings.commit({
    start, end,
    idempotencyKey: "ik_call_42",
    title: "Discovery call",
    invitee: { name: "Ada Lovelace", email: "[e-mail]" },
  });
  console.log("booked:", booking.bookingId);
} catch (e) {
  if (e instanceof Conflict) {
    console.log(`outranked by ${e.winningAgentId} (rank ${e.winningAgentPriority})`);
  } else {
    throw e;
  }
}

title and invitee ({ name?, email?, notes? }) are first-class fields: persisted on the booking, returned on the Booking object, and shown to the calendar owner in the dashboard. A top-level title supersedes a legacy metadata.title. client.agents.me() also returns the owner's timezone so a client can render slots in their zone.

A losing agent gets a typed Conflict error, not a timeout — it knows who won, by what priority, and where the audit row lives, so fallback behavior is a clean instanceof away.

Authentication

API keys are issued from the AgentDraft dashboard and start with avs_live_. Pass it via the constructor or set AGENTDRAFT_API_KEY in the environment.

new AgentDraft({ apiKey: "avs_live_..." });
// or:
process.env.AGENTDRAFT_API_KEY = "avs_live_...";
new AgentDraft();

For local development against a dev backend, pass baseUrl: or set AGENTDRAFT_BASE_URL.

Surface

Attribute	Purpose
client.availability	Read merged availability across all agents writing to the calendar
client.bookings	hold, release, commit, cancel — the four state transitions
client.agents	me() — confirm key + current priority + scopes
client.mailbox	Inbound/outbound mail surface for agents that book via email

Error types

• Conflict — your write was outranked. Carries winningAgentId, winningAgentPriority, winningBookingId, auditEventId.
• AuthError — bad/missing/expired API key.
• RateLimited — token bucket exhausted. Has retryAfterSeconds.
• RuleViolation — request was syntactically valid but violated a rule.
• ApiError — base class.

Idempotency

Pass idempotencyKey to bookings.commit({...}). The server caches the result by (agentId, key) for 24 hours, so retries return the original booking, not a duplicate.

Supply chain

Releases are cut from the publish-typescript-sdk.yml workflow on ts-sdk-v* tag pushes. npm view agentdraft shows the published tarball metadata. npm provenance attestations are temporarily disabled pending a move to github-hosted runners — see ryabinski-labs/agentdraft#168.

Verify an approval receipt

A downstream service can verify a signed approval or consent receipt offline with the public JWKS:

import { hashEvidence, verifyApprovalToken } from "agentdraft";

const claims = await verifyApprovalToken(receipt, {
  audience: "https://deploy.example.com",
  actionType: "deploy.production",
  evidenceSha256: hashEvidence(requestPayload),
});
// claims.sub is the human; claims.act.sub is the agent.

verifyApprovalToken checks the Ed25519 signature, issuer, audience, expiry, act.sub, and the RAR entry. Pass jwks for an air-gapped verifier; otherwise the public JWKS is fetched and cached for five minutes.
