Recommended Skills
Journey fit
Ongoing personal and business money tracking is operate-time iteration, not a one-off build task. Iterate covers recurring financial review loops as you adjust spending, pricing, and runway.
How it compares
Agent-side finance rollup from pasted or file data, not a connected neobank or accounting MCP.
Common Questions / FAQ
Who is finance-manager for?
Solo builders and consultants who manually track or export transactions and want agent help summarizing burn, savings rate, and category trends.
When should I use finance-manager?

Is finance-manager safe to install?
