Stop drowning in AI .md files.
Flanner is a free, open-source CLI and MCP server for the planning docs your AI agents generate. Those files scatter in two directions at once, across your repos on disk and across the issues in your tracker, and flanner is the control point for both, versioning every revision and linking each plan to the issue it belongs to.
