Fail-fast removes hidden fallback behavior and legacy compatibility paths that make code harder to reason about, test, and operate reliably.
Ask the agent to run the fail-fast scanner on your repository, then return a prioritized list of fallback smells to remove and the exact code/test changes needed to make failures explicit.

Removing hidden fallback behavior requires scanning a codebase for implicit defaulting and permissive env handling, then refactoring findings into explicit validation contracts. This workflow enforces deterministic failure modes when inputs or dependencies are missing.
Swallowed error handling hides missing dependencies and boundary failures through silent degradation. Replacing it with explicit error rethrowing and context prevents hidden compatibility paths from masking critical runtime failures.
Enforcing typed env schema validation replaces legacy option aliasing and permissive environment handling with strict validation contracts. This ensures deterministic builds by failing explicitly when environment variables are missing.
Static analysis identifies optional dependency degradation by running a scanner that classifies findings into remove, require, validate, or keep categories. This targets legacy branches and narrows edits to enforce explicit compatibility paths.
Adding failure-mode tests after narrowing edits to remove fallback paths proves deterministic failure. These tests explicitly verify that missing inputs or dependencies trigger validation errors rather than silent degradation.
Python 3 is required to run the fail-fast scanner, which analyzes your repository and returns a prioritized list of fallback smells. The scanner identifies exact code changes needed to make failures explicit across your environments.
