# Claude Code Skill > 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". Use when this capability is needed. - Skill: `tomevault-io/claude-code-skill-2` (Agent Skill, multi-file: 2 files) - Install (CLI): `npx skillmds@latest add tomevault-io/claude-code-skill-2` - Raw SKILL.md: https://api.skillmd.com/api/skills/tomevault-io/claude-code-skill-2/raw - Safety review: pending - Works with: Claude Code, Claude.ai, OpenAI Codex - Category: AI & ML - Author: tomevault-io (https://skillmd.com/u/tomevault-io) - Updated: 2026-09-17 - Page: https://skillmd.com/skills/tomevault-io/claude-code-skill-2 --- # 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 | Engine | CLI | Session Type | Best For | |--------|-----|-------------|----------| | `claude` | `claude` | Persistent subprocess | Multi-turn, complex tasks | | `codex` | `codex exec` | Per-message spawn | One-shot execution | | `gemini` | `gemini -p` | Per-message spawn | One-shot execution | | `cursor` | `agent -p` | Per-message spawn | One-shot execution | ## Core Workflow ```javascript // 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 | Parameter | Description | |-----------|-------------| | `engine` | `claude` (default), `codex`, `gemini`, `cursor` | | `model` | Model name or alias (`opus`, `sonnet`, `haiku`, `gpt-5.4`, `gemini-pro`, `composer-2`) | | `permissionMode` | `acceptEdits`, `auto`, `plan`, `bypassPermissions`, `default` | | `effort` | `low`, `medium`, `high`, `max`, `auto` | | `maxBudgetUsd` | Cost limit in USD | | `allowedTools` | List of allowed tool names | ### CLI 2.1.111 options | Parameter | Description | |-----------|-------------| | `bare` | Minimal mode — no CLAUDE.md, hooks, LSP, auto-memory. Auto-enables prompt cache optimizations (see below). | | `includeHookEvents` | Stream hook lifecycle events (PreToolUse/PostToolUse). | | `permissionPromptTool` | Delegate permission prompts to an MCP tool for non-interactive use. | | `excludeDynamicSystemPromptSections` | Move cwd/env/git from system prompt to user message for better prompt cache hits. Auto-enabled with `bare: true`. | | `enablePromptCaching1H` | Enable 1-hour prompt cache TTL (vs default 5-min). Auto-enabled with `bare: true`. | | `debug` / `debugFile` | Targeted debug output by category (e.g. `"api,mcp"`) and optional file path. | | `fromPr` | Resume a session linked to a GitHub PR number or URL. | | `channels` / `dangerouslyLoadDevelopmentChannels` | MCP channel subscriptions (research preview). | **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. ```javascript // 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](references/council.md) ## Cross-Session Messaging Sessions can communicate. Idle sessions receive immediately; busy sessions queue. ```javascript 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) - **Claude**: native `/team` and `@teammate` commands - **Codex/Gemini/Cursor**: virtual teams via cross-session inbox routing ```javascript 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. ## 27 Tools Overview | Category | Tools | |----------|-------| | Session Lifecycle | `claude_session_start`, `claude_session_send`, `claude_session_stop`, `claude_session_list`, `claude_sessions_overview` | | Session Ops | `claude_session_status`, `claude_session_grep`, `claude_session_compact`, `claude_session_update_tools`, `claude_session_switch_model` | | Inbox | `claude_session_send_to`, `claude_session_inbox`, `claude_session_deliver_inbox` | | Teams | `claude_agents_list`, `claude_team_list`, `claude_team_send` | | Council | `council_start`, `council_status`, `council_abort`, `council_inject`, `council_review`, `council_accept`, `council_reject` | | Ultra | `ultraplan_start`, `ultraplan_status`, `ultrareview_start`, `ultrareview_status` | For full parameter reference: see [references/tools.md](references/tools.md) ## 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` --- > Source: [shendiid/openclaw-claude-code](https://github.com/shendiid/openclaw-claude-code) — distributed by [TomeVault](https://tomevault.io).
