# 🏠 tilde

> *Your AI agents' home directory*

**tilde** is a privacy-first [Model Context Protocol](https://modelcontextprotocol.io/) (MCP) server that acts as the universal memory and profile layer for AI Agents.

Configure once. Use everywhere. Your data, your control.

---

## The Problem

Every time you switch AI tools, you face the same issues:

- **🔄 Repetition**: "I'm a Senior SWE", "I prefer Python", "Don't use ORMs"
- **🧩 Fragmentation**: Preferences learned in Cursor aren't available in Claude
- **🔒 Privacy Concerns**: Unsure who has access to your personal context

## The Solution

**tilde** acts as a "digital passport" that your AI agents can read:

```
┌────────────────────────────────────────────────────────────┐
│  Claude Desktop  │   Cursor   │  Windsurf  │  Your Agent   │
└────────┬─────────┴─────┬──────┴─────┬──────┴───────┬───────┘
         │               │            │              │
         └───────────────┴─────┬──────┴──────────────┘
                               │
                    ┌──────────▼──────────┐
                    │   tilde MCP Server  │
                    │   (runs locally)    │
                    └──────────┬──────────┘
                               │
                    ┌──────────▼──────────┐
                    │   ~/.tilde/profile  │
                    │   (your data)       │
                    └─────────────────────┘
```

---

## MCP Tools

| Tool | Description |
|------|-------------|
| `get_profile` | Retrieve full or partial profile |
| `get_team_context` | Get team-specific context |
| `propose_update` | Agent proposes a profile update (queued for approval) |
| `list_pending_updates` | List updates awaiting user approval |

---

## CLI Commands

```bash
tilde init                    # Create default profile
tilde show                    # Display current profile
tilde show skills             # Show skills section only
tilde show --full             # Show full content without truncation
tilde edit                    # Open profile in $EDITOR
tilde config                  # Show current configuration
tilde pending                 # List pending agent updates
tilde approve <id> [id2...]   # Approve one or more updates
tilde reject <id> [id2...]    # Reject one or more updates
tilde approve --all           # Approve all pending updates
tilde reject --all            # Reject all pending updates
tilde approve --all -e <id>   # Approve all except one
tilde log                     # View update history
tilde ingest <file>           # Extract insights from a document
tilde export --format json    # Export profile
```

### Document Ingestion

```bash
# Ingest a book and extract insights
tilde ingest "~/Books/DDIA.pdf" --topic data_systems

# Dry run to preview what would be extracted
tilde ingest notes.md --dry-run

# Auto-approve high-confidence updates
tilde ingest paper.pdf --auto-approve 0.8
```

### Resume Import

Bootstrap your profile from an existing resume:

```bash
# Import resume (PDF, DOCX, or text)
tilde ingest ~/Documents/resume.pdf --type resume

# Preview what would be extracted
tilde ingest resume.pdf --type resume --dry-run

# Auto-approve high-confidence items
tilde ingest resume.pdf --type resume --auto-approve 0.8
```

The resume importer extracts:
- **Identity**: Name, role, years of experience
- **Experience**: Work history with companies, roles, dates
- **Education**: Degrees, institutions, graduation years
- **Tech Stack**: Programming languages, frameworks, tools
- **Projects**: Personal and open-source projects
- **Publications**: Papers, patents, articles

### Skills Management

Manage Anthropic-format skills with full bundling support:

```bash
# Import skills from Anthropic skills directory
tilde skills import /path/to/skills

# Import specific skills by name
tilde skills import /path/to/skills -n mcp-builder -n pdf

# Dry run to preview import
tilde skills import ./skills --dry-run

# Import as private skills
tilde skills import ./skills --visibility private

# List all imported skills
tilde skills list

# Export skills to Anthropic format
tilde skills export ./my-skills

# Export specific skill
tilde skills export ./output -n mcp-builder

# Delete skills
tilde skills delete skill-name
tilde skills delete --all --force
```

The skill importer bundles:
- **SKILL.md**: Skill content with YAML frontmatter
- **scripts/**: Python scripts and utilities
- **references/**: Documentation files
- **templates/**: Template files
- **assets/**: Static assets
- **Root files**: LICENSE.txt, etc.

All bundled resources are preserved through import → persist → export.

### Team Management

```bash
# Create a team
tilde team create myteam --name "My Startup" --org "ACME Corp"

# Activate team context (applies to all profile queries)
tilde team activate myteam

# Sync team config from URL or git repo
tilde team sync https://example.com/team.json --activate
tilde team sync git@github.com:myorg/team-config.git --activate

# List and manage teams
tilde team list
tilde team show
tilde team edit
tilde team deactivate
```

---

## Storage Backends

tilde supports multiple storage backends:

| Backend | Use Case | Command |
|---------|----------|---------|
| **YAML** (default) | Human-readable, git-friendly | `TILDE_STORAGE=yaml` |
| **SQLite** | Queryable, memories, faster at scale | `TILDE_STORAGE=sqlite` |
| **Mem0** | Semantic search via embeddings | `TILDE_STORAGE=mem0` |

```bash
# Use SQLite backend
export TILDE_STORAGE=sqlite
tilde init

# Query profile fields (SQLite only)
uv run python -c "
from tilde.storage import get_storage
storage = get_storage(backend='sqlite')
print(storage.query('%languages%'))
"
```

---

## Configuration

tilde uses a centralized configuration for LLM and embedding settings. Configuration is stored in `~/.tilde/config.yaml` and can be synced across devices.

### Configuration Priority

1. **Environment variables** (highest priority)
2. **Config file** (`~/.tilde/config.yaml`)
3. **Built-in defaults** (lowest priority)

### Environment Variables

| Variable | Description | Default |
|----------|-------------|---------|
| `GOOGLE_API_KEY` | Google/Gemini API key (primary) | Required |
| `OPENAI_API_KEY` | OpenAI API key (fallback) | Optional |
| `TILDE_LLM_MODEL` | LLM model for document ingestion | `gemini-3-flash-preview` |
| `TILDE_EMBEDDING_MODEL` | Embedding model for semantic search | `gemini-embedding-001` |
| `TILDE_STORAGE` | Storage backend (yaml, sqlite, mem0) | `yaml` |
| `TILDE_PROFILE` | Custom profile path | `~/.tilde/profile.yaml` |

### Managing Configuration

```bash
# View current configuration
tilde config

# Save settings to config file (for syncing across devices)
tilde config --save

# Modify a setting and save
tilde config --set llm_model=gemini-1.5-pro

# Show config file path
tilde config --path
```

> **Note**: API keys are NEVER saved to the config file for security. Always set them via environment variables.

### Quick Setup

```bash
# Minimal setup (just one API key!)
export GOOGLE_API_KEY="your-google-api-key"

# Save your settings for this device
tilde config --save

# Now you can use all features
tilde ingest paper.pdf
```

### Syncing Across Devices

The config file at `~/.tilde/config.yaml` is designed to be synced:

1. **Via dotfiles repo**: Add `~/.tilde/` to your dotfiles
2. **Via cloud sync**: Dropbox, iCloud, or similar
3. **Manually**: Copy the file to new devices

Example config file:
```yaml
llm_model: gemini-3-flash-preview
llm_temperature: 0.7
embedding_model: gemini-embedding-001
embedding_dimensions: 768
storage_backend: yaml
```

### Programmatic Configuration

```python
from tilde.config import get_config, call_llm, get_embedding, save_config

# Check current config
config = get_config()
print(f"Provider: {config.provider}")
print(f"LLM Model: {config.llm_model}")

# Use directly
response = call_llm("Summarize this document...")
embedding = get_embedding("Some text to embed")
```

- [x] **Phase 4**: Team sync for B2B use cases
- [x] **Phase 5**: SQLite and Mem0 storage backends
- [x] **Phase 6**: Skill Management (Anthropic SKILL.md format)
  - [x] Batch import from directory with `tilde skills import`
  - [x] Export to directory with `tilde skills export`
  - [x] Full bundling of scripts, references, templates, assets
  - [x] Deduplication by skill name

## Why "tilde"?

In Unix, `~` (tilde) represents your home directory — the place where your personal configuration lives. **tilde** is the home for your AI identity.

---

## Philosophy

1. **Your Data, Your Control**: Local by default, sync only if you choose
2. **Human-in-the-Loop**: Agents propose, humans decide
3. **Portable & Open**: Export anytime, no lock-in, works with any MCP tool
4. **Progressive Disclosure**: Start simple, add complexity as needed
