Problem Solved
What problem does Reason solve?
It's for engineering teams and developers who spend hours on bug fixes, performance tuning, and reporting. Today they manually reproduce issues, trace code, write tests, and assemble decks from scattered data. Reason takes a plain-language task, spawns subagents to read code, run benchmarks, edit files, and verify fixes, then reports back with a merged PR or generated artifacts. For example, a developer asks Reason to find why the nightly export is slow; it profiles the job, batches the queries, and reports a 14x speedup with passing tests.
