cicada

Personal second-brain memory for the user. Use when the user references something they told you before, asks "what do I know about X", shares a decision, fact, or link worth keeping, or when starting a session where prior context would help. Backed by the Cicada MCP server and a local, git-versioned markdown knowledge graph.

Turns the user's own agent (Claude Code, Codex, Cursor — whatever runs this skill) into Cicada's consolidation engine, no Cicada API key required. Use at the end of a working session, whenever the user says "remember this" / "consolidate our chat", or right after watching a video with claude-video. Also covers capturing episodes and URLs mid-conversation.
