zylos-ai

C4 communication bridge — central gateway for ALL external communication (Telegram, Lark, etc.). Use when replying to users via the "reply via" path, sending proactive messages to external channels, querying recent conversations or checkpoint status (prefer c4-db.js CLI; sqlite3 OK for unsupported queries), fetching conversation history for Memory Sync, or creating checkpoints after sync. Incoming messages are queued by channel bots and delivered to Claude via a PM2 dispatcher daemon. Session-start hooks automatically provide conversation context and can trigger Memory Sync when unsummarized conversations exceed the configured threshold.

Built-in web interface for communicating with Claude without external services. Use when setting up or configuring the web console channel, or troubleshooting browser-based access.

Guardian service that monitors the active runtime agent's state and automatically restarts it if stopped. Use when checking agent liveness state or understanding the auto-restart mechanism.

Guidelines for managing zylos components via CLI and C4 channels. Use when installing, upgrading, or uninstalling components, or when user asks about available components.

Start a new session when context is high. Claude uses /clear, Codex uses /exit. Use when context is high or when a fresh session is needed.

Use when the user asks to restart Claude Code, or after changing settings/hooks/keybindings.

Upgrade Claude Code to the latest version with graceful shutdown and auto-restart. Use when the user asks to upgrade or when a new Claude Code version is available.

Guide for creating effective skills. Use when asked to create a new skill (or update an existing skill) that extends Claude's capabilities with specialized knowledge, workflows, or tool integrations.

Lark (international) and Feishu (飞书, China) communication channel. Use when: (1) replying to Lark/Feishu messages (DM or group @mentions), (2) sending proactive messages or media (images, files) to Lark/Feishu users or groups, (3) managing DM access control (dmPolicy: open/allowlist/owner, dmAllowFrom list), (4) managing group access control (groupPolicy, per-group allowFrom, smart/mention modes), (5) operating Feishu/Lark productivity surfaces via the bundled lark-cli — documents, sheets, slides, multidim Base, calendar, tasks, mail, drive, wiki/whiteboard, OKR, approval, attendance, video conferencing, minutes, native OpenAPI explorer (see "Bundled Capability Modules" section in SKILL.md body — full module index under references/), (6) configuring the bot (admin CLI, markdown card settings, verification token, encrypt key), (7) troubleshooting Lark webhook or service issues.
