About this integration

Connect Fixer to Definable to triage issues, review pull requests, monitor builds. Personas call Fixer's 3 tools directly from chat or scheduled flows. Wire it into a triage, review, or release-management persona — every action runs scoped, reviewable, and logged.

Connect Fixer to Definable and it becomes a set of typed tools your agents plan with — triggered by events, run on schedules, or invoked mid-conversation. Every write is checked by the verifier before it lands.
