Agenten-Kompass

TASK Develop software

Investigate and fix a bug in your code

You have a reproducible bug and want a focused change. A coding agent can investigate the code, prepare a small diff and run tests.

Agents to start with

  • Cursor

    For working in an AI editor with configurable approvals for terminal commands.

  • Claude Code

    For working in the terminal or in your existing development environment.

  • GitHub Copilot Cloud Agent

    For work assigned from a GitHub issue and returned as a pull request for review.

Examples for this task

Sample task to adapt

Fix a bug in the code.

Read the project rules. Investigate [error], propose a small change, and run the relevant checks. Show me the diff and any remaining uncertainties.

Documented use cases

How to approach it

Understand an existing project and implement a clearly limited change.

  1. Provide project rules and acceptance criteria
  2. Create the change in a dedicated workspace
  3. Check tests, diff, and visible behavior

What to check

In addition to tests and the build, check the actual user flow.

Compare the working environment, model choice, approvals and billing.
