Example task library

Start with a proven development task.

Explore practical examples of work Kepler can execute autonomously. Each template represents a focused outcome with an explicit verification path.

9 use cases Backend to delivery Verification included

Templates and examples

Adapt the repository, acceptance criteria, constraints, and verification commands to match your project.

Backend

Add REST endpoint

Implement a production-ready endpoint with validation, error handling, API documentation, and focused integration tests.

Testing

Fix failing tests

Reproduce the failure, identify the root cause, apply the smallest safe fix, and verify the full test suite.

  • pytest
  • Jest
  • CI
Architecture

Refactor module

Improve a module's structure and maintainability while preserving its public behavior and regression coverage.

  • Python

Delivery

Resolve CI failure

Inspect pipeline logs, repair the broken build or verification step, and confirm the workflow succeeds end to end.

  • GitHub Actions
  • Docker
  • YAML
Data

Add database migration

Create a reversible schema migration, update the data layer, and test both upgrade and rollback paths.

  • PostgreSQL
  • Alembic

  • Observability
  • Logging
  • API
Maintenance

Update dependencies safely

Upgrade selected packages, address compatibility changes, run security checks, and verify no regressions.

  • npm
  • pip
  • Security
Frontend

Improve accessibility

What every task includes

Scope. Implement. Verify. Deliver.

Kepler inspects the relevant code, makes the scoped change, runs the supplied checks, and returns reviewable output. These examples are starting points, not one-click actions.
