Comparisons vs alternatives

FAQ

What does Tonone's Lens do?
Lens is the AI analytics and BI engineer in the Tonone team for Claude Code. It builds dashboards where every chart answers one question and has one owner, defines metrics frameworks from North Star through operational metrics, builds automated reporting pipelines with scheduled delivery and alerts, and audits existing analytics setups for conflicting definitions, broken queries, and unused dashboards.
How is Lens different from just writing SQL myself?
Lens frames every query as part of a metrics framework, each metric has one definition, one owner, and one action threshold. It also reviews SQL for production-scale performance, checks for conflicting existing definitions before adding a new one, and produces full dashboard specifications that explain why each chart exists and what decision it enables.
Can Lens build dashboards for Metabase, Looker, or Redash?
Yes. Lens produces dashboard specifications and SQL formatted for the conventions of specific BI tools including Metabase, Looker, Redash, and Grafana. For teams with custom internal dashboards, it produces query and chart specifications that a frontend engineer can implement directly.
What is a metrics framework and why does it matter?
A metrics framework is a structured hierarchy of metrics: a single North Star metric that captures the core value the business delivers, input metrics that measure the levers teams can pull to move the North Star, and operational metrics that diagnose which part of the system is working and which is not. Without a framework, teams end up with a collection of disconnected numbers where no one agrees which ones matter. Lens builds the framework first so every subsequent dashboard is grounded in a shared measurement strategy.
How does Lens handle conflicting metric definitions?
The lens-audit skill inventories existing dashboards and identifies metrics that appear in multiple places with different SQL definitions, the most common source of analytics distrust. It surfaces these conflicts explicitly, proposes canonical definitions, and flags which dashboards need to be updated. Lens runs recon before building any new metric to avoid adding to the conflict.
Is Tonone's Lens free to use?
Yes. Tonone is MIT-licensed and free to use. Lens is one of 23 agents included in the Tonone package for Claude Code. You pay only for Claude Code token usage during the analytics work itself.
What SQL optimization does Lens perform?
Lens reviews queries for index usage, scan patterns, join order, and execution plan implications at production data scale. It adds guards like NULLIF for division operations, uses CTEs for clarity and performance, and structures queries to take advantage of existing indexes rather than triggering full table scans.
Can Lens set up automated Slack reporting?
Yes. The lens-report skill builds automated reporting pipelines that include Slack delivery with formatted block messages, email delivery for executive summaries, and threshold alerts that notify a channel when a metric crosses a configured value. It produces the SQL, scheduling configuration, and delivery specification together.
