Initialize a new dazense project

dazense init

This will create a new dazense project in the current directory. It will prompt you for a project name and ask you to configure:

• Database connections (BigQuery, DuckDB, Databricks, Snowflake, PostgreSQL)
• Git repositories to sync
• LLM provider (OpenAI, Anthropic, Mistral, Gemini)
• Slack integration
• Notion integration

The resulting project structure looks like:

<project>/
├── dazense_config.yaml
├── .dazenseignore
├── RULES.md
├── databases/
├── queries/
├── docs/
├── semantics/
├── repos/
├── agent/
│   ├── tools/
│   └── mcps/
└── tests/

Options:

• --force / -f: Force re-initialization even if the project already exists

Start the dazense chat UI

dazense chat

This will start the dazense chat UI. It will open the chat interface in your browser at http://localhost:5005.

Test connectivity

dazense debug

Tests connectivity to all configured databases and LLM providers. Displays a summary table showing connection status and details for each resource.

Sync resources

dazense sync

Syncs configured resources to local files:

• Databases — generates markdown docs (columns.md, preview.md, description.md, profiling.md) for each table into databases/
• Git repositories — clones or pulls repos into repos/
• Notion pages — exports pages as markdown into docs/notion/

After syncing, any Jinja templates (*.j2 files) in the project directory are rendered with the dazense context.

Run tests

dazense test

Runs test cases defined as YAML files in tests/. Each test has a name, prompt, and expected sql. Results are saved to tests/outputs/.

Options:

• --model / -m: Models to test against (default: openai:gpt-4.1). Can be specified multiple times.
• --threads / -t: Number of parallel threads (default: 1)

Examples:

dazense test -m openai:gpt-4.1
dazense test -m openai:gpt-4.1 -m anthropic:claude-sonnet-4-20250514
dazense test --threads 4

Explore test results

dazense test server

Starts a local web server to explore test results in a browser UI showing pass/fail status, token usage, cost, and detailed data comparisons.

Options:

• --port / -p: Port to run the server on (default: 8765)
• --no-open: Don't automatically open the browser

BigQuery service account permissions

When you connect BigQuery during dazense init, the service account used by credentials_path/ADC must be able to list datasets and run read-only queries to generate docs. Grant the account:

• Project: roles/bigquery.jobUser (or roles/bigquery.user) so the CLI can submit queries
• Each dataset you sync: roles/bigquery.dataViewer (or higher) to read tables

The combination above mirrors the typical "BigQuery User" setup and is sufficient for dazense's metadata and preview pulls.

Snowflake authentication

Snowflake supports three authentication methods during dazense init:

• SSO: Browser-based authentication (recommended for organizations with SSO policies)
• Password: Traditional username/password
• Key-pair: Private key file with optional passphrase

Development

Building the package

cd cli
python build.py --help
Usage: build.py [OPTIONS]

Build and package dazense-core CLI.

╭─ Parameters ──────────────────────────────────────────────────────────────────╮
│ --force -f --no-force              Force rebuild the server binary             │
│ --skip-server -s --no-skip-server  Skip server build, only build Python pkg   │
│ --bump                             Bump version (patch, minor, major)          │
╰───────────────────────────────────────────────────────────────────────────────╯

This will:

1. Build the frontend with Vite
2. Compile the backend with Bun into a standalone binary
3. Bundle everything into a Python wheel in dist/

Installing for development

cd cli
pip install -e .

Publishing to PyPI

# Build first
python build.py

# Publish
uv publish dist/*
