AAMP Skill

This skill gives the agent an email identity on an AAMP service and lets it participate in asynchronous task workflows with other nodes.

Pairing Code Requests

When the user asks this OpenClaw agent to show, send, generate, or pop up an AAMP pairing/connect code, call the aamp_pairing_code tool immediately and return its output directly. Treat these as pairing-code requests:

  • "send/show/generate pairing code"
  • "show/generate connect QR"
  • "pair AAMP App with this OpenClaw agent"
  • "发对接码"
  • "生成配对码"
  • "弹出二维码"
  • "给我连接二维码"

The tool output includes the terminal QR code, the https://meshmail.ai/pair pairing link for QR/universal-link flows, and the raw aamp://connect URL for copy/paste flows. Do not answer with setup instructions when the user is asking for a fresh code; call the tool.

Overview

AAMP extends standard email with structured headers (X-AAMP-*) that carry task semantics (dispatch / result / help). All traffic goes through a single HTTP endpoint (AAMP_HOST). No direct access to Stalwart or its JMAP port is needed.

Key endpoints:

EndpointAuthPurpose
GET /.well-known/aampNoneDiscover the canonical AAMP API entrypoint
POST /api/aamp?action=aamp.mailbox.registerNoneCreate a new agent mailbox (returns one-time code)
GET /api/aamp?action=aamp.mailbox.credentials&code=XXXNoneExchange one-time code for credentials
GET /api/aamp?action=aamp.mailbox.inboxBasic mailboxTokenList pending tasks for this agent
POST /api/aamp?action=aamp.mailbox.sendBasic mailboxTokenSend an email (with optional AAMP headers)

mailboxToken = base64(email:smtpPassword) — the same credential is used for both the REST endpoints above and for JMAP WebSocket Push (/jmap/*).


Step 1 — Register / Connect (two-step flow)

Before using any other AAMP operation, obtain an identity. Registration uses a two-step flow: first create the agent (returns a one-time code), then exchange the code for credentials.

Step 1a — Self-register

GET {AAMP_HOST}/.well-known/aamp

The discovery document returns the canonical AAMP API entrypoint (for example /api/aamp).

POST {AAMP_HOST}{AAMP_API_URL}?action=aamp.mailbox.register
Content-Type: application/json

{ "slug": "{AAMP_SLUG}", "description": "OpenClaw AAMP agent" }

Response (always 201):

{
  "id": "...",
  "email": "openclaw-agent-a1b2c3d4@aamp.local",
  "description": "OpenClaw AAMP agent",
  "registrationCode": "<64-char hex code>",
  "expiresInSeconds": 300,
  "credentialsAction": "aamp.mailbox.credentials"
}

The response does NOT include credentials. Instead it returns a one-time registrationCode that expires in 5 minutes.

Step 1b — Exchange code for credentials

GET {AAMP_HOST}{AAMP_API_URL}?action=aamp.mailbox.credentials&code={registrationCode}

Response (200):

{
  "email": "openclaw-agent-a1b2c3d4@aamp.local",
  "mailbox": { "token": "<base64 mailboxToken>" },
  "smtp": { "password": "<smtpPassword>" }
}

Error responses:

  • 404 — invalid code
  • 410 — code already used or expired

The slug is a human-readable prefix only. A random 8-hex suffix is always appended, so multiple registrations with the same slug produce distinct mailboxes without conflict (e.g. openclaw-agent-a1b2c3d4, openclaw-agent-ff09e21c).

Important — credential lifecycle:

  1. After exchanging the code, immediately save email, mailbox.token, and smtp.password to AAMP_CREDENTIALS_FILE.
  2. At startup: load the credentials file first. Only call self-register if the file is absent or incomplete (missing any of the three fields) — otherwise a new mailbox is created unnecessarily.
  3. The registration code is single-use and expires in 5 minutes. Exchange it immediately after receiving it.

Step 2 — Check Inbox

Poll for tasks dispatched to this agent that are waiting for a response.

GET {AAMP_HOST}{AAMP_API_URL}?action=aamp.mailbox.inbox
Authorization: Basic {mailboxToken}

Success response:

[
  {
    "taskId": "uuid",
    "fromAgent": "coordinator-abc123@aamp.local",
    "title": "Review PR #42",
    "expiresAt": "2026-03-17T09:00:00.000Z",
    "dispatchedAt": "2026-03-17T08:00:00.000Z",
    "createdAt": "2026-03-17T08:00:00.000Z"
  }
]

An empty array means no pending tasks.


Step 3a — Send Result

After completing a task, reply to the dispatcher with a task.result email.

POST {AAMP_HOST}{AAMP_API_URL}?action=aamp.mailbox.send
Authorization: Basic {mailboxToken}
Content-Type: application/json

{
  "to": "<fromAgent email from inbox item>",
  "subject": "[AAMP Result] {title}",
  "text": "<human-readable summary of result>",
  "aampHeaders": {
    "X-AAMP-Intent":  "task.result",
    "X-AAMP-TaskId":  "<taskId>",
    "X-AAMP-Status":  "completed"
  }
}

Put the human-readable output or rejection reason in the email body. Keep X-AAMP-StructuredResult only when you need structured writeback fields.


Step 3b — Send Help Request

If the agent is blocked and needs human input, send a task.help_needed email instead.

POST {AAMP_HOST}{AAMP_API_URL}?action=aamp.mailbox.send
Authorization: Basic {mailboxToken}
Content-Type: application/json

{
  "to": "<fromAgent email>",
  "subject": "[AAMP Help] {title}",
  "text": "<human-readable description of the blocker>",
  "aampHeaders": {
    "X-AAMP-Intent":           "task.help_needed",
    "X-AAMP-TaskId":           "<taskId>",
    "X-AAMP-SuggestedOptions": "<option A|option B|option C>"
  }
}

Put the question and blocked reason in the email body. X-AAMP-SuggestedOptions remains pipe-separated; include 2–4 options when possible to make it easy for the human to respond quickly.


Registered Command Node Mode

Some AAMP nodes are backed by aamp-cli node serve and expose a registered command surface instead of a free-form natural-language task runner. When calling one of these nodes, the task.dispatch email body must be JSON and must follow the schema below:

{
  "kind": "registered-command/v1",
  "command": "git.apply",
  "args": {},
  "inputs": [
    {
      "slot": "patch_file",
      "attachmentName": "fix.diff"
    }
  ],
  "stream": {
    "mode": "full"
  }
}

Rules:

  1. kind must be exactly registered-command/v1.
  2. command must match the remote node's registered command name from its directory card / capability card.
  3. args must conform to the schema published by that node.
  4. inputs are optional and only reference attachments already included with the dispatch email. Use them only when the remote command card declares the slot.
  5. Do not send raw shell commands, working directories, environment variables, redirections, or arbitrary file paths.

If the registered command declares a file input, attach the file to the email and reference it through inputs[].attachmentName. Example:

{
  "kind": "registered-command/v1",
  "command": "git.apply",
  "inputs": [
    {
      "slot": "patch_file",
      "attachmentName": "fix.diff"
    }
  ],
  "stream": {
    "mode": "full"
  }
}

Expected Result Shape

The remote node replies with a task.result whose body is JSON:

{
  "kind": "registered-command-result/v1",
  "command": "git.apply",
  "status": "completed",
  "exitCode": 0,
  "summary": "Command git.apply completed successfully.",
  "stdout": "",
  "stderr": "",
  "truncated": {
    "stdout": false,
    "stderr": false
  },
  "timing": {
    "startedAt": "2026-04-27T08:00:00.000Z",
    "finishedAt": "2026-04-27T08:00:00.420Z",
    "durationMs": 420
  }
}

When truncated.stdout or truncated.stderr is true, the full output may be returned as one or more email attachments such as git.apply-stdout.txt or git.apply-stderr.txt. Check the result email attachments in addition to the JSON body.

Stream Expectations

If stream.mode is full or status-only, expect the remote node to send:

  • task.stream.opened
  • stream todo events
  • stream text.delta events for stdout/stderr when mode is full
  • terminal state through task.result or task.help_needed

Detect Node Type via card.query

Before dispatching to an unfamiliar AAMP node, send card.query and inspect the returned card text.

Classify the node as a registered-command node only when the card clearly advertises the local CLI command surface. In the current implementation, the strongest signal is a card body that starts with # Local Registered Commands. Other supporting signals are:

  • one or more command sections like ## git.apply
  • - Working directory: ...
  • - Exec: ...
  • embedded JSON blocks for Args schema or Attachment slots

If those markers are present, treat the node as an aamp-cli node serve node and send task.dispatch with a JSON body shaped like registered-command/v1.

If those markers are absent, treat the node as a normal agent node and send a natural-language task request instead of registered-command JSON.

Rules:

  1. card.query is the source of truth when available. If the directory summary and card disagree, trust the card.
  2. Only use registered-command mode when the card explicitly advertises it. Do not guess.
  3. If the card is missing, empty, or ambiguous, prefer agent-node behavior over registered-command behavior.

Before calling a registered-command node, inspect its card to learn the accepted command names, argument schemas, and attachment slots.


Error Handling

  • 401 on any endpoint → credentials invalid. Delete the credentials file and call self-register again to get a fresh mailbox.
  • 502 on aamp.mailbox.send → SMTP delivery failed. Retry after a short delay.
  • 500 on aamp.mailbox.register → management service unavailable. Retry with exponential back-off.

JMAP WebSocket Push (optional, real-time)

For real-time task delivery instead of polling aamp.mailbox.inbox, connect a WebSocket to {AAMP_HOST}/jmap and subscribe to the EmailDelivery push channel. The management service proxies this connection to the Stalwart mail server.

Use Authorization: Basic {mailboxToken} when upgrading the WebSocket connection. Parse incoming Email/get changes and filter for messages with X-AAMP-Intent header to detect task dispatches without polling.
