name: claude-code-skill description: Manage persistent coding sessions across Claude Code, Codex, Gemini, and Cursor engines. Use when orchestrating multi-engine coding agents, starting/sending/stopping sessions, running multi-agent council collaborations, cross-session messaging, ultraplan deep planning, ultrareview parallel code review, or switching models/tools at runtime. Triggers on "start a session", "send to session", "run council", "ultraplan", "ultrareview", "switch model", "multi-agent", "coding session", "session inbox", "cursor agent". metadata: { "openclaw": { "emoji": "🤖", "requires": { "anyBins": ["claude", "codex", "gemini", "agent"] }, "install": [ { "id": "npm-plugin", "kind": "node", "package": "@enderfga/openclaw-claude-code", "label": "Install plugin (npm)" }, { "id": "node-claude", "kind": "node", "package": "@anthropic-ai/claude-code", "bins": ["claude"], "label": "Install Claude Code CLI" }, { "id": "node-codex", "kind": "node", "package": "@openai/codex", "bins": ["codex"], "label": "Install Codex CLI" }, { "id": "node-gemini", "kind": "node", "package": "@google/gemini-cli", "bins": ["gemini"], "label": "Install Gemini CLI" } ] } }

Claude Code Skill

Persistent multi-engine coding session manager. Wraps Claude Code, Codex, Gemini, and Cursor CLIs into headless agentic engines with 27 tools.

Engine Quick Reference

Core Workflow

// 1. Start session (any engine)
claude_session_start({ name: "myproject", cwd: "/path/to/project", engine: "claude" })
claude_session_start({ name: "codex-task", cwd: "/path/to/project", engine: "codex" })
claude_session_start({ name: "gemini-task", cwd: "/path/to/project", engine: "gemini" })
claude_session_start({ name: "cursor-task", cwd: "/path/to/project", engine: "cursor" })

// 2. Send messages
claude_session_send({ name: "myproject", message: "Fix the auth bug" })

// 3. Check status / search history
claude_session_status({ name: "myproject" })
claude_session_grep({ name: "myproject", pattern: "error" })

// 4. Stop when done
claude_session_stop({ name: "myproject" })

Session Options

CLI 2.1.111 options

CLI 2.1.121 options

stats.pluginErrors is now populated from the system/init event when CLI plugins fail to load due to unmet dependencies.

TRACEPARENT / TRACESTATE (W3C distributed tracing) are automatically forwarded from parent process env — set them before starting the session and they propagate to the child Claude CLI.

Smart defaults: When bare: true, the plugin auto-enables --exclude-dynamic-system-prompt-sections and ENABLE_PROMPT_CACHING_1H=1 unless explicitly set to false.

Multi-Agent Council

Parallel agent collaboration with git worktree isolation and consensus voting. Agents can use different engines.

// Start a council
council_start({
  task: 'Build a REST API',
  agents: [
    { name: 'Architect', emoji: '🏗️', persona: 'System design', engine: 'claude' },
    { name: 'Engineer', emoji: '⚙️', persona: 'Implementation', engine: 'codex' },
  ],
  maxRounds: 5,
  projectDir: '/path/to/project',
});

Council lifecycle: council_start → poll council_status → council_review → council_accept or council_reject.

For details: see references/council.md

Cross-Session Messaging

Sessions can communicate. Idle sessions receive immediately; busy sessions queue.

claude_session_send_to({ from: "sender", to: "receiver", message: "Auth module needs rate limiting" })
claude_session_send_to({ from: "monitor", to: "*", message: "Build failed!" })  // broadcast
claude_session_inbox({ name: "receiver" })
claude_session_deliver_inbox({ name: "receiver" })

Team Tools (All Engines)

All engines use the same virtual-team layer: cross-session inbox routing across active SessionManager sessions. (Claude Code's native experimental Agent Teams is in-process TUI only and not reachable from a subprocess wrapper.)

claude_team_list({ name: "myproject" })
claude_team_send({ name: "myproject", teammate: "teammate", message: "Review this" })

Ultraplan & Ultrareview

• Ultraplan: Opus deep planning session (up to 30 min), produces detailed implementation plan
• Ultrareview: Fleet of 5-20 bug-hunting agents reviewing in parallel (security, logic, perf, types, etc.)

Both are async — start then poll status.

Authentication Prerequisites

Each engine requires its own auth before use:

• Claude: claude /login or ANTHROPIC_API_KEY
• Codex: codex login or OPENAI_API_KEY
• Gemini: gemini login or GEMINI_API_KEY
• Cursor: agent login or CURSOR_API_KEY
