ConnectOnion Agent Networking

Connect to remote ConnectOnion agents, delegate tasks, and handle multi-turn collaboration.

Environment Setup

Before any interaction, verify the environment is ready. Run these checks sequentially — stop on first failure:

1. Check connectonion is installed:

python -c "import connectonion; print(connectonion.__version__)"

If ImportError: run pip install connectonion, then re-check.

2. Check agent identity exists:

ls .co/keys/agent.key 2>/dev/null || ls ~/.co/keys/agent.key 2>/dev/null

If neither exists: run co init to generate identity.

3. Verify identity is usable:

python -c "
from connectonion import address
from pathlib import Path
a = address.load(Path('.co')) or address.load(Path.home() / '.co')
print(a['address'])
"

If fails: report the error and stop. The user needs to fix their .co/ directory.

Note: import connectonion prints [env] ... lines to stdout. For all environment checks, parse only the last line of stdout output. Ignore everything else.

Skip environment checks after the first successful run in a session.

Connecting to a Remote Agent

Parsing User Intent

Extract from the user's message:

• Target address: match regex 0x[0-9a-fA-F]{64} (66 chars total)
• Task description: everything else

For /oo slash command: /oo <address> <task description>

Connection Strategy: Direct-First with Relay Fallback

The default connect() library has a known issue: the relay API may not return an online field, causing direct endpoint resolution to always fail and falling back to relay — which itself may be unreliable. To work around this, the skill uses a smart connection script that:

1. Queries the relay API for the agent's registered endpoints
2. Tries each endpoint directly (verifying via /info)
3. Falls back to relay only if all direct endpoints fail

One-shot Task

Generate and execute this Python script (fill in {address} and {task}):

TARGET = "{address}"
TASK = "{task}"
TIMEOUT = 60
RELAY_URL = "wss://oo.openonion.ai"

keys = address.load(Path(".co")) or address.load(Path.home() / ".co")

    def priority(url):
        if "localhost" in url or "127.0.0.1" in url:

        if any(x in url for x in ("192.168.", "10.", "172.16.", "172.17.", "172.18.")):

Execute via your shell tool. Parse stdout — only lines starting with CO_ matter, ignore all others. The CO_RESPONSE value is JSON-encoded (to handle multi-line responses). Decode it before presenting to the user.

• CO_DONE: True → return CO_RESPONSE content to the user. Done.
• CO_DONE: False → the remote agent is asking a follow-up question. See Multi-turn Task below.
• CO_METHOD: direct → connected directly (fastest path).
• CO_METHOD: relay → connected via relay fallback.
• CO_DIRECT_FAIL: ... → direct failed, trying relay next.
• CO_RELAY_FAIL: ... → both methods failed. Report error to user.

For long-running tasks, increase timeout to 300.

Multi-turn Task

Multi-turn requires maintaining session state. Use separate one-shot calls per turn since stdin interaction is unreliable in agent environments. Each turn is a new connection but passes context through the conversation.

For the first turn, use the one-shot script above. For follow-up turns, include conversation context in the prompt (e.g., prepend prior exchanges).

Response Handling

After each round, parse stdout — only CO_ prefixed lines matter, ignore all others:

• CO_DONE: True → return CO_RESPONSE content to the user. Done.
• CO_DONE: False → the remote agent asked a follow-up question:

- If you can answer from context (file contents, prior conversation, your own knowledge) → answer automatically. Do not bother the user. - If you need the user's input → show CO_RESPONSE to the user, wait for their reply, then send another round. - Loop until CO_DONE: True or 10 rounds.

Error Handling

If the script fails, check stderr for these patterns:
