description: Route plain-language requests for Claude Code, Cursor, Copilot, OpenClaw ACP, OpenCode, Gemini CLI, Grok Build, Qwen, Kiro, Kimi, iFlow, Factory Droid, Kilocode, or explicit ACP harness work into either OpenClaw ACP runtime sessions or direct acpx-driven sessions ("telephone game" flow). For coding-agent thread requests, read this skill first, then use only `sessions_spawn` for thread creation. Codex chat binding defaults to the native Codex app-server plugin unless ACP is explicit or background spawn needs ACP.

ACP Harness Router

When user intent is "run this in Claude Code/Cursor/Copilot/OpenClaw/OpenCode/Gemini/Grok Build/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 / Grok Build / 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"`
• "grok build" or "grok-build" -> `agentId: "grok-build"`
• "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.

`grok-build` is an ACPX agent target, not the xAI model id `xai/grok-build-0.1`. Route `grok-build` through `agentId`; use the fully qualified xAI ref only in an OpenClaw `model` field.

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:

• check that 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.

ACPX install and version policy (direct acpx path)

For this repo, direct `acpx` calls must follow the same pinned policy as the `@openclaw/acpx` extension package.

1. Prefer plugin-local binary, not global PATH:

• `${ACPX_PLUGIN_ROOT}/node_modules/.bin/acpx`

2. Resolve pinned version from extension dependency:

• `node -e "console.log(require(process.env.ACPX_PLUGIN_ROOT + '/package.json').dependencies.acpx)"`

3. If binary is missing or version mismatched, install plugin-local pinned version:

• `cd "$ACPX_PLUGIN_ROOT" && npm install --omit=dev --no-save acp
