the open reflex commons

Give your AI agents reflexes.

Skills are what your agent can do. Reflexes are how you'd do it.

    if (ctx.tool === "Bash" && ctx.command?.includes("--force"))
      return deny("open a PR — don't force-push shared history");

01 in the moment

Caught the instant before it runs.

Same reflexes, every agent. Switch tabs — the command runs through the hook either way.

fired: the proactive move you'd have made
blocked: the mistake you'd never make
paused: the call only you should make
