Acp Router

ACP Harness Router

When user intent is "run this in Claude Code/Cursor/Copilot/OpenClaw/OpenCode/Gemini/Qwen/Kiro/Kimi/iFlow/Droid/Kilocode (ACP harness)", do not use subagent runtime or PTY scraping. Route through ACP-aware flows.

Codex is special: plain chat/conversation binding and control should use the native Codex app-server plugin (/codex bind, /codex threads, /codex resume) instead of the default ACP path. Use ACP for Codex only when the user explicitly names ACP//acp/acpx, or when spawning background child sessions through sessions_spawn where a native Codex runtime spawn is not available yet.

Intent detection

Trigger this skill when the user asks OpenClaw to:

• run something in Claude Code / Cursor / Copilot / OpenClaw / OpenCode / Gemini / Qwen / Kiro / Kimi / iFlow / Droid / Kilocode
• run Codex explicitly through ACP, /acp, or acpx
• continue existing harness work
• relay instructions to an external coding harness
• keep an external harness conversation in a thread-like conversation

Mandatory preflight for coding-agent thread requests:

• Before creating any thread for ACP harness work, read this skill first in the same turn.
• After reading, follow OpenClaw ACP runtime path below; do not use message(action="thread-create") for ACP harness thread spawn.

Mode selection

Choose one of these paths:

1. OpenClaw ACP runtime path (default): use sessions_spawn / ACP runtime tools.
2. Direct acpx path (telephone game): use acpx CLI through exec to drive the harness session directly.

Use direct acpx when one of these is true:

• user explicitly asks for direct acpx driving
• ACP runtime/plugin path is unavailable or unhealthy
• the task is "just relay prompts to harness" and no OpenClaw ACP lifecycle features are needed

Do not use:

• subagents runtime for harness control
• /acp command delegation as a requirement for the user
• PTY scraping of supported ACP harness CLIs when acpx is available

AgentId mapping

Use these defaults when user names a harness directly:

• "openclaw" -> agentId: "openclaw"
• "claude" or "claude code" -> agentId: "claude"
• "codex" -> agentId: "codex" only for explicit ACP/acpx requests or background ACP runtime spawn
• "copilot" or "github copilot" -> agentId: "copilot"
• "cursor" or "cursor cli" -> agentId: "cursor"
• "droid" or "factory droid" -> agentId: "droid"
• "opencode" -> agentId: "opencode"
• "gemini" or "gemini cli" -> agentId: "gemini"
• "iflow" -> agentId: "iflow"
• "kilocode" -> agentId: "kilocode"
• "kimi" or "kimi cli" -> agentId: "kimi"
• "kiro" or "kiro cli" -> agentId: "kiro"
• "qwen" or "qwen code" -> agentId: "qwen"

These defaults match current acpx built-in aliases.

If policy rejects the chosen id, report the policy error clearly and ask for the allowed ACP agent id.

OpenClaw ACP runtime path

Required behavior:

1. For ACP harness thread spawn requests, read this skill first in the same turn before calling tools.
2. Use sessions_spawn with:
   • runtime: "acp"
   • thread: true
   • mode: "session" (unless user explicitly wants one-shot)
3. For ACP harness thread creation, do not use message with action=thread-create; sessions_spawn is the only thread-create path.
4. Put requested work in task so the ACP session gets it immediately.
5. Set agentId explicitly unless ACP default agent is known.
6. Do not ask user to run slash commands or CLI when this path works directly.

Example:

User: "spawn a test codex ACP session in thread and tell it to say hi"

Call:

{
  "task": "Say hi.",
  "runtime": "acp",
  "agentId": "codex",
  "thread": true,
  "mode": "session"
}

Thread spawn recovery policy

When the user asks to start a coding harness in a thread, treat that as an ACP runtime request and try to satisfy it end-to-end.

Required behavior when ACP backend is unavailable:

1. Do not immediately ask the user to pick an alternate path.
2. First attempt automatic local repair:
   • ensure plugin-local pinned acpx is installed in the ACPX plugin package
   • verify ${ACPX_CMD} --version
3. After reinstall/repair, restart the gateway and explicitly offer to run that restart for the user.
4. Retry ACP thread spawn once after repair.
5. Only if repair+retry fails, report the concrete error and then offer fallback options.

When offering fallback, keep ACP first:

• Option 1: retry ACP spawn after showing exact failing step
• Option 2: direct acpx telephone-game flow

Do not default to subagent runtime for these requests.
