My router said sonnet. The invoice said fable

Ax, a new open-source tool, monitors coding agent sessions to identify repeated mistakes and generate repo-specific fixes. Built by Necmttn, it runs locally with SurrealDB and aims to improve agent performance by turning session data into actionable insights.

into a better next run.

Built because we got tired of guessing what actually works.

ax watches every session your coding harness runs, spots the mistakes it repeats, and turns them into small, repo-specific fixes you review and apply — one at a time.

paste it - your agent installs ax, labels your skills, and tells you which ones to actually use✓ Copied - paste into your coding agent for the guided setup

Your sessions, working for the next one. #

Every session lands in one local graph your agent can reach back into — to catch a repeat mistake, replay a clean run, recover the moment a test fails, or grade the harness itself. Same loop, whatever you run it in.

Mission Control for your agents. #

Run ax serve

and the whole HUD lights up — archetype sigil, live activity, streaks, token spend by model. The wrapped highlights pop out as ax finds them.

Maps the whole repo before touching a line — reads wide, edits once.
