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.

Turn every agent session 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. 73% lands cheap - Segment the pipeline · what feeds the graph FTS median 5.9ms 128 applied → agents every event → typed graph → ranked interventions. local SurrealDB at 127.0.0.1 . see /features for the schema → /features six forms: skill · guidance · subagent · hook · automation · harness check If it shapes your agent, you should be able to fork it.
