Give Claude Code a memory that never forgets

---

Features

• Automatic context — Relevant memories are loaded at the start of every session, so Claude already knows what you've been working on
• Mid-session memory — As you work, relevant memories are surfaced automatically based on what you're asking about
• Session capture — When you end a session, your conversation is automatically summarized and stored with tool-aware compression
• Session recall — Pick up exactly where you left off with /claude-cognis:recall
• Personal + team memory — Your memories are private by default; team knowledge is shared across everyone on the same repo
• Semantic search — Find past decisions, patterns, and context using natural language queries
• Codebase indexing — Analyze and store your project's architecture so Claude understands your codebase from the first message
• Memory stats — See what Cognis has stored with /claude-cognis:memory-stats
• Smart context assembly — Cognis intelligently combines short-term and long-term memory to build the most relevant context

Quick Start

1. Get your API key at studio.lyzr.ai

2. Install the plugin

In Claude Code, run:

/plugin marketplace add Lyzr-Cognis/claude-cognis
/plugin install claude-cognis

3. Set your API key

export LYZR_API_KEY="your-api-key"

Or save it permanently in ~/.cognis-claude/settings.json:

{ "apiKey": "your-api-key" }

That's it. Cognis will automatically load memories when you start a session and save them when you stop.

Architecture

How It Works

Hooks

Cognis uses Claude Code's hook system to work automatically in the background.

Hook	Trigger	What it does
SessionStart	Every new session	Loads relevant personal and team memories into context
UserPromptSubmit	Each user message	Surfaces relevant memories mid-session based on what you're working on
Stop	Session ends	Summarizes the conversation and saves it to memory with tool-aware compression

Skills

Natural language triggers — just talk to Claude and the right skill activates.

Skill	Trigger phrases	What it does
cognis-search	"what did I work on?", "find that decision about..."	Searches your memories using semantic search
cognis-save	"remember this", "save this as project knowledge"	Saves specific information to persistent memory

MCP Tools

For advanced usage, Cognis exposes 8 tools via the Model Context Protocol.

Tool	Description
add_memory	Store information in long-term memory
search_memories	Semantic search across personal and/or team memories
get_memories	List stored memories without a search query
update_memory	Update an existing memory's content or metadata
delete_memory	Delete a specific memory by ID
delete_all_memories	Clear all memories for a session (requires confirmation)
get_context	Intelligent context assembly combining short-term and long-term memory
search_summaries	Search past session summaries and key decisions

Commands

Command	Description
/claude-cognis:index	Analyze and index the current codebase
/claude-cognis:recall	Recall last session context to pick up where you left off
/claude-cognis:memory-stats	Show memory statistics and recent session history
/claude-cognis:project-config	Configure per-project settings
/claude-cognis:logout	Remove stored API credentials
