# Features

> Hooks, MCP tools, skills, and commands — everything Claude-Cognis provides

## Hooks

Cognis uses Claude Code's hook system to work automatically in the background. No manual action needed.

| Hook                 | Trigger           | What happens                                                                                                                                            |
| -------------------- | ----------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **SessionStart**     | Every new session | Loads relevant personal and team memories into context. Claude starts with knowledge of your past work                                                  |
| **UserPromptSubmit** | Each user message | Searches for relevant memories based on your prompt (first 150 chars). Injects matching memories if relevance > 0.5. Skips trivial inputs ("yes", "ok") |
| **Stop**             | Session ends      | Parses the conversation transcript, compresses tool outputs intelligently, and saves the session summary to Cognis                                      |

### Tool-Aware Compression

The Stop hook doesn't store raw transcripts. Instead, it compresses tool outputs:

| Tool           | Compression                              |
| -------------- | ---------------------------------------- |
| Edit/MultiEdit | `Edited file.js: 'old' → 'new'`          |
| Write          | `Wrote file.js (50 lines)`               |
| Read           | `Read file.js (100 lines)`               |
| Bash           | Command + output preview (max 200 chars) |
| Glob           | `Found 23 files matching '**/*.ts'`      |
| Grep           | `Searched for 'pattern': 42 matches`     |

## 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...", "search my memory for..." | Searches personal and/or team memories using semantic search    |
| **cognis-save**   | "remember this", "save this as project knowledge", "store this decision"        | Saves information to persistent memory (personal or team scope) |

## MCP Tools

8 tools exposed via the Model Context Protocol for direct memory operations.

| Tool                  | Description                                                             |
| --------------------- | ----------------------------------------------------------------------- |
| `add_memory`          | Store information in long-term memory. Supports personal or team scope  |
| `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 — combines short-term and long-term memory |
| `search_summaries`    | Search past session summaries and key decisions                         |

## Commands

| Command                         | Description                                                                                 |
