​
Connect to an agent

import { AgentClient } from '@samvad-protocol/sdk'

// Fetches the remote agent card and builds a typed client
const client = await AgentClient.from('https://other-agent.com')
from() fetches /.well-known/agent.json, loads the public key, and generates a local Ed25519 keypair stored in .samvad/client-keys/ (created if absent).

​
Sync call

const result = await client.call('review-code', {
  code: 'function foo() {}',
  language: 'typescript',
})
// result is the skill's typed output
call() builds a signed envelope, sends it to POST /agent/message, and returns the parsed result. Throws SamvadError on protocol errors.

​
Async task

// Fire-and-forget with webhook — agent POSTs result to your callback URL
const taskId = await client.task(
  'review-code',
  { code: '...' },
  'https://my-agent.com/agent/message'
)

// No webhook — SDK polls automatically with configurable interval/timeout
const result = await client.taskAndPoll('review-code', { code: '...' }, {
  intervalMs: 500,
  timeoutMs: 60_000,
})

​
SSE streaming

for await (const chunk of client.stream('review-code', { code: '...' })) {
  process.stdout.write(String(chunk))
}
stream() sends to POST /agent/stream and returns an async generator over SSE chunks. The stream ends when the agent sends "done": true.

​
Calling a trusted-peers skill

A trusted-peers skill only accepts callers whose agent:// ID and public key are registered on the server. Use AgentClient.prepare() to generate the client keypair before connecting, so you can register it first: 
// 1. Generate client identity without connecting
const client = await AgentClient.prepare()

// 2. Register the client's public key on the server
serverAgent.trustPeer(client.agentId, client.publicKey)

// 3. Now connect and call
await client.connect('https://server-agent.com')
const result = await client.call('internal-skill', { data: '...' })

​
Error handling

import { SamvadError, ErrorCode } from '@samvad-protocol/sdk'

try {
  const result = await client.call('review-code', { code: '...' })
} catch (err) {
  if (err instanceof SamvadError) {
    switch (err.code) {
      case ErrorCode.RATE_LIMITED:
        // back off and retry
        break
      case ErrorCode.AUTH_FAILED:
        // signature verification failed or bearer token missing
        break
      case ErrorCode.SCHEMA_INVALID:
        // input didn't match the skill's schema
        break
    }
  }
}
