cosq 0.6.1

Quick Start

# Install (macOS / Linux)
brew install mklab-se/tap/cosq

# Or via cargo
cargo install cosq

# Login to Azure
cosq auth login

# Initialize with a Cosmos DB account
cosq init

# Run a query
cosq query "SELECT * FROM c"

# Output as table or CSV
cosq query "SELECT * FROM c" --output table
cosq query "SELECT * FROM c" --output csv

# Pipe-friendly (JSON to stdout, metadata to stderr)
cosq query "SELECT c.name FROM c" -q | jq '.[].name'

Stored Queries

Save and reuse parameterized queries as .cosq files:

# Create a stored query (opens in editor)
cosq queries create recent-users

# List all stored queries
cosq queries list

# Run a stored query (interactive parameter prompts)
cosq run recent-users

# Run with parameters from the command line
cosq run recent-users -- --days 7

# Browse and pick a query interactively
cosq run

Multi-Step Queries

Query across multiple containers in a single stored query:

# ~/.cosq/queries/order-details.cosq
---
description: Get order with customer details
params:
  - name: orderId
    type: string
steps:
  - name: order
    container: orders
  - name: customer
    container: customers
template: |
  Order: {{ order[0].id }}
  Customer: {{ customer[0].name }}
---
-- step: order
SELECT * FROM c WHERE c.id = @orderId

-- step: customer
SELECT * FROM c WHERE c.id = @order.customerId

Steps execute in dependency order — independent steps run in parallel, while steps referencing @step.field wait for that step to complete.

AI Query Generation

Generate stored queries from natural language — the AI samples your actual documents for field-accurate SQL and auto-generates output templates:

# Set up AI (auto-detects Claude, Codex, Copilot, Ollama, or Azure OpenAI)
cosq ai init

# Fully interactive: pick database, container, describe your query
cosq queries generate

# Or provide a description directly
cosq queries generate "active users by region in the last 30 days"

# Target a specific database/container
cosq queries generate --db mydb --container users "top 10 by login count"

See INSTALL.md for all installation methods, shell completions, and platform-specific instructions.
