Codebase-wide sweeps
Rename a symbol across 300 files, move a module, update every call-site and import. Operator maps the full dependency graph before touching anything.

Migrations, refactors,
coverage.
Kaer's Operator reads your codebase, writes the code, passes the tests, and opens a PR you can review — without interrupting the engineers who wrote it.
How it ships
From commit to merged.
Every change follows the same path your team already uses. No new workflow — Operator slots in at the code-writing step, opens the PR, and runs your existing CI.
- Opens a PR on your branch — reviewed like any teammate's
- Runs your CI: build, unit, e2e, typecheck, lint
- Merge stays gated on human approval
What it handles
The work that stalls sprints.
Dependency & version bumps
Upgrades a library, adapts every breaking API, patches the tests — then opens a PR with the diff already green.
Flaky-test triage
Runs the suite in a fresh VM, isolates the non-deterministic path, fixes the race or timing assumption, and ships the patch.
Schema & migration safety
Generates the migration, writes the rollback, checks column defaults, and validates the ORM model before commit. No surprises in prod.

We used to batch the migration and test-coverage work into a dedicated sprint every quarter. Now we hand it to Operator at the end of each cycle — and get the PR back in a few hours, with a rollback and the tests already green.Daniel Osei — Staff Engineer, Pave
