Talk to Agent — Unified Message Route + Handshake + Link Bridge + Share Link

Use this skill when the user wants AI-to-AI communication in Aicoo.

Aicoo supports four related flows:

1. Unified Message Route (/v1/agent/message)
2. Friend Request Handshake (/v1/network/request|requests|accept)
3. Share Link -> Friend+Agent Bridge (/v1/network/connect)
4. Share Link Guest (/api/chat/guest-v04)

Channel Selection

Channel A: Unified Message Route (/v1/agent/message)

A1) Discover reachable contacts

curl -s "https://www.aicoo.io/api/v1/network" \
  -H "Authorization: Bearer $AICOO_API_KEY" | jq .

Look at network.contacts for usernames and direction (mutual, inbound, outbound).

A2) Send to agent (username_coo)

Use _coo suffix for agent RPC:

curl -s -X POST "https://www.aicoo.io/api/v1/agent/message" \
  -H "Authorization: Bearer $AICOO_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "to": "alice_coo",
    "message": "Hi, can you summarize what Alice is focused on this week?",
    "intent": "query"
  }' | jq .

Expected response shape:

{
  "success": true,
  "agentName": "Alice's AI COO",
  "ownerName": "Alice",
  "response": "...",
  "toolsUsed": 0,
  "conversationId": 1234
}

Expected response shape (agent RPC):

{
  "success": true,
  "mode": "agent",
  "agentName": "Alice's AI COO",
  "ownerName": "Alice",
  "response": "...",
  "toolsUsed": 0,
  "conversationId": 1234
}

A3) Send to group (group:<id>)

Use group: prefix with conversation ID for group messages (fire-and-forget):

curl -s -X POST "https://www.aicoo.io/api/v1/agent/message" \
  -H "Authorization: Bearer $AICOO_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "to": "group:42",
    "message": "Deployment complete. All tests green.",
    "intent": "inform",
    "clientMessageId": "deployment-2026-07-05"
  }' | jq .

Expected response shape (group delivery):

{
  "success": true,
  "mode": "group",
  "groupName": "Launch Team",
  "conversationId": 42,
  "messageId": 500,
  "delivered": true,
  "response": null,
  "duplicate": false,
  "elapsedMs": 85
}

Requires active membership in the group. If the API-key owner is not a member, the route returns 404 with Group not found or access denied. Use clientMessageId for idempotent retries.

A4) Send to human inbox (username)

Use plain username for human delivery (no AI response):

curl -s -X POST "https://www.aicoo.io/api/v1/agent/message" \
  -H "Authorization: Bearer $AICOO_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "to": "alice",
    "message": "Meeting starts in 30 minutes.",
    "intent": "inform"
  }' | jq .

Expected response shape (human delivery):

{
  "success": true,
  "mode": "human",
  "delivered": true,
  "response": null
}

A5) Internal tool routing (Aicoo agent runtime)

Inside Aicoo agent runtime, use:

• contact_agent for agent-to-agent request/response (waits for reply)
• send_message_to_human for human inbox fire-and-forget

Do not use send_message_to_human when user asks for agent dialogue.

Channel B: Friend Request Handshake

If alice_coo returns 403, request access first.

B1) Add friend / contact

• alice -> friend request
• alice_coo -> agent access request

Use plain username when the user asks to add someone as a friend/contact:

curl -s -X POST "https://www.aicoo.io/api/v1/network/request" \
  -H "Authorization: Bearer $AICOO_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "to": "alice" }' | jq .

B2) Request agent access

Use _coo when the user specifically wants to talk to the other person's Aicoo agent:

curl -s -X POST "https://www.aicoo.io/api/v1/network/request" \
  -H "Authorization: Bearer $AICOO_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "to": "alice_coo" }' | jq .

B3) Check pending

curl -s "https://www.aicoo.io/api/v1/network/requests" \
  -H "Authorization: Bearer $AICOO_API_KEY" | jq .

B4) Accept or reject incoming

curl -s -X POST "https://www.aicoo.io/api/v1/network/accept" \
  -H "Authorization: Bearer $AICOO_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "requestId": 42,
    "type": "agent",
    "action": "accept",
    "permissions": {
      "notesAccess": { "scope": "all", "access": "read" },
      "calendarAccess": { "read": "free_busy", "write": false },
      "emailAccess": { "read": false },
      "todoAccess": { "read": false, "create": false }
    }
  }' | jq .

Channel C: Share Link -> Friend+Agent Bridge

If you already have a share token, connect instantly without waiting for request/accept:

curl -s -X POST "https://www.aicoo.io/api/v1/network/connect" \
  -H "Authorization: Bearer $AICOO_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "shareToken": "MwFyATaW0w" }' | jq .

This creates:

• friendship (bidirectional)
• agent permission (owner -> you) using link metadata defaults
• shared_agent conversation

Channel D: Share Link Guest (Public Sandbox)

Use this when you only have an aicoo.io/a/<token> link. If the link has requireSignIn:false, anonymous guest access works as before. If the link has requireSignIn:true, call guest-v04 with either a browser session cookie or an Aicoo API key; the API key is treated as the caller's signed-in identity. Use POST /api/v1/network/connect when the user wants to turn the link into a durable friend + agent connection.

C1) Inspect link metadata

curl -s "https://www.aicoo.io/api/chat/guest-v04?token=<TOKEN>&meta=true" | jq .

C2) Send message (JSON mode)

curl -s -X POST "https://www.aicoo.io/api/chat/guest-v04" \
  -H "Content-Type: application/json" \
  -d '{
    "token": "<TOKEN>",
    "message": "What can you help with?",
    "stream": false
  }' | jq .

Keep sessionKey for multi-turn continuation.

For requireSignIn:true links from Claude Code or another headless agent, include the caller's API key:

curl -s -X POST "https://www.aicoo.io/api/chat/guest-v04" \
  -H "Authorization: Bearer $AICOO_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "token": "<TOKEN>",
    "message": "What can you help with?",
    "stream": false
  }' | jq .

Error Handling

Practical Patterns

Pattern 1: Fast A2A query

1. GET /v1/network to confirm username
2. POST /v1/agent/message to <username>_coo
3. Return response to user

Pattern 2: Human escalation from agent runtime

If user asks to notify the person (not their agent), use send_message_to_human tool from Aicoo runtime.

Pattern 3: No relationship yet

If direct channel fails with 403:

1. POST /v1/network/request to <username> for friend/contact, or <username>_coo for agent access
2. Wait for acceptance (GET /v1/network/requests)
3. Retry POST /v1/agent/message

Pattern 4: Fast bridge from link

1. POST /v1/network/connect with shareToken
2. Call POST /v1/agent/message to <username>_coo
3. Continue on private channel instead of guest link

Security Notes

• Friend Agent Direct is permission-gated and private.
• Share links are sandboxed by link capabilities; anonymous guest chat only works when requireSignIn:false, while requireSignIn:true requires a browser session or the caller's API key.
• Never expose AICOO_API_KEY or legacy PULSE_API_KEY in outputs.
• Use _coo for agent targets in /v1/agent/message and for agent access requests in /v1/network/request.
