chartr Turns Multi-Agent Work Into a Star Map Built From the Planning Agent's Own Files
rengwu/chartr (MIT, Go 1.26+ with a Svelte frontend, created 2026-07-21) reached 219 stars and was pushed again on August 2. It multiplexes several coding agent CLIs in tabbed shell sessions, but the interesting part is that its interactive star-map is generated from .plan/maps/ files that the planning agent writes, so the visualization is a byproduct of planning rather than a separate diagramming step. Tickets sit on a frontier; assigning an unblocked one opens a session with the map, the ticket and its blockers' answers already loaded into the buffer. It ships a cgo-free binary serving 127.0.0.1:8787 plus a macOS .dmg and a Linux AppImage. Version 0.2.1, self-described as alpha with breaking changes expected before 1.0.
