Validation And Fix

Use when running existing project validation commands and fixing failures after code changes, including lint, type-check, unit/integration test, build, CI, or local script failures. Do not use when the task is to design or author new component/E2E tests; Chinese triggers include validation, check fa

Verify and fix

Purpose

Automatically execute existing verification commands, analyze the reasons for failure and safely repair them to ensure that quality access control meets standards.

Procedure

1. Identify available commands from package.json or repository documentation.
2. Prioritize execution in the following order:
   • lint
   • type-check
   • unit/integration tests
   • build
3. Read the failure output carefully.
4. Group errors by file, error type and dependency, prioritizing root causes that block subsequent diagnosis.
5. Fix one type of problem at a time and display or log critical error context.
6. After each critical repair, re-execute the affected command to confirm whether the error is reduced.
7. If the same error still fails to be repaired three times in a row, stop expanding changes and report blocking.
8. Finally, press Expected Output to summarize the execution results, repair content and remaining risks.

Failure Triage

• Fix the earliest errors that will cascade first, such as missing types, import failures, and configuration parsing failures.
• Differentiate between real product bugs, test environment issues, snapshot drift, dependency version changes and flaky.
• Log Node version, package manager, environment variables, path case, and working directory differences for CI-specific failures.
• When fixing tests, give priority to fixing product code or testing waiting methods, instead of deleting assertions to cover up real regressions.

Constraints

• Do not blindly turn off rules to eliminate errors
• Don't compromise type safety to pass checks unless there is a clear reason to do so
• Don’t rewrite irrelevant modules just because a nearby test fails
• Do not modify multiple irrelevant root causes at once
• Don't remove failing tests to make validation pass
• Don't just run a fragment of the failed command and claim that the overall validation passed

Detailed reference

When writing a verification fix report, load references/report-template.md.

Expected Output

• All verification commands such as lint/type-check/test/build passed
• Failed items have been fixed or given clear reasons and follow-up actions
• The fix report is saved as reports/validation-fix-YYYY-MM-DD-HHmmss.md
