nao Labs Changelog - March 7-14, 2026

This week brings foundational improvements to analytics discovery and enterprise deployment options. Database profiling enables data teams to understand table characteristics within nao's context system, Microsoft Fabric support adds SQL Analytics endpoints for Fabric customers, and Microsoft Teams deployment lets business users query data directly in their workspace. We also shipped context window visualization so you can see exactly how much context your queries consume, an improved chat interface with data context shortcuts, and KPI card support for quick metric views.

Highlights

Database profiling for warehouse discovery

Added profiling accessor across DuckDB, PostgreSQL, and MSSQL warehouses. The profiling feature generates summary statistics, column information, and top values for tables, automatically included in the agent context. Teams can configure refresh policies to balance context freshness against query costs.

Microsoft Fabric Data Warehouse and SQL Analytics Endpoint support

New database connector for Microsoft Fabric with four authentication modes: SQL password, Azure CLI, Azure Interactive (browser-based AD), and service principal. Handles ODBC token injection, pandas 2.0+ compatibility, and proper system schema filtering for production reliability.

Microsoft Teams bot deployment channel

Deployed nao as a Microsoft Teams bot, enabling business users to query data without leaving their workspace. The bot supports chat, story sharing, and image rendering within Teams native UI, filling the gap between web and Slack integrations.

Context window visualization in chat input

Added real-time context token tracking as a donut ring in the chat input bar. Shows current token usage against the model's limit, helping teams understand how much context remains before hitting truncation. Updates dynamically as context is added or cleared.

Added a plus menu in chat input for inserting Story mode, available skills, and database table mentions. Includes a context picker that reads your databases folder, making it faster to reference specific tables without typing.
