Fix Your Angular Bug Fast is a skill published by agensi that assists developers in diagnosing and resolving bugs in Angular applications. When invoked, the skill analyses the problem described and works to identify the root cause, then provides ready-to-use solutions and step-by-step debugging guidance.

The skill covers several common Angular problem areas. For component issues, it helps explain why the UI is not updating, often tracing the problem to change detection or incorrect state mutations. For RxJS bugs, it can diagnose subscription management errors, operator misuse, and observable lifecycle problems. It also addresses HTTP and API call failures, helping to isolate issues in interceptors, error handling, or response mapping. Lifecycle-related problems — such as incorrect use of ngOnInit, ngOnDestroy, or change detection hooks — are within its scope. Finally, it can assist with unit test failures written in Jest, explaining why a test is failing and suggesting corrected test code.

This skill is the right choice when a developer has an active Angular bug and needs a clear explanation of what is going wrong alongside concrete code-level fixes. It does not replace a full static analysis tool or a linter, and it has no access to a running application’s runtime state — it works entirely from the description and code the developer provides.

Use cases

  • Diagnose why an Angular component's UI is not reflecting state changes
  • Fix RxJS subscription or operator errors causing unexpected behavior
  • Debug HTTP client calls that fail or return unexpected data
  • Resolve Angular lifecycle hook misuse causing runtime errors
  • Identify and correct failing Jest unit tests in an Angular project
  • Understand the root cause of a service not behaving as expected

When to use it

  • A developer has a specific Angular bug and can describe or paste the relevant code
  • RxJS observable chains are producing unexpected or no output
  • HTTP calls in an Angular service are failing or returning malformed data
  • Jest unit tests for Angular components or services are failing without a clear reason
  • Angular lifecycle hooks are triggering at unexpected times or not at all

When not to use it

  • The project does not use Angular — this skill is Angular-specific and not for React, Vue, or other frameworks
  • A full automated code review or linting pipeline is needed rather than targeted bug fixing
  • The issue requires runtime inspection of live browser state or network traffic
  • No code or error description can be provided, as the skill has no access to external environments
