Software that gets better at your work.
commonshell makes tools for people who build software. Our first product, Pathfinder, is a task agent that remembers what worked, what failed and why, and brings that back the next time you work on the same project.
See PathfinderWhat we build
Local first
Your tasks, learnings and project files stay on your Mac. Nothing needs a server of ours to run.
Memory that is checked
Learnings are recorded with their outcome and date. Old answers are superseded, not silently reused.
Measured, not promised
We publish our method and our numbers, including the results that did not show a gain.
Pathfinder
A local-first task agent for macOS. Run Claude Code in tabs, plan work into tasks, and let the agent recall what it learned in earlier sessions. Pathfinder can also run your web tests in a browser you can watch, and be reached from your phone.
