Use when reviewing scripts, client components, bundles, or runtime behavior related to Parse JSON safely with error handling. Inspect both source code and the browser execution path so fixes target the real bottleneck or bug.
インストールする前に、エージェントに与えられる指示の中身を確認できます。
JSON.parse() on invalid input throws a SyntaxError that will crash your application if uncaught. API responses, localStorage values, and user-provided data can all be malformed. Safe parsing with validation catches these errors at the point of parsing, not deep in your application logic when a missing property causes an unexpected error.
Find all JSON.parse() calls in this file and check whether each one is wrapped in try/catch and whether the result is validated before use.
Add try/catch error handling to all JSON.parse() calls and add shape validation to protect against unexpected data structures.
Explain why JSON.parse can throw, what safe JSON parsing looks like, and when to use schema validation libraries.
Review scripts, client components, and browser execution paths related to Parse JSON safely with error handling. Flag exact imports, event handlers, runtime side effects, or blocking operations that violate the rule, and state how the change should be verified in the browser.

概要と使いどころ
Use when reviewing templates, rendered HTML, or shared components related to Create a custom 404 error page. Validate the final browser-facing markup, not just the source framework abstraction.

Use when auditing metadata, crawlability, structured data, or indexability related to Create a dedicated About page. Verify the rendered HTML and HTTP response rather than relying only on source files.

Use when reviewing component libraries, page flows, or CI pipelines that need repeatable accessibility checks. Automated testing is strongest at catching structural and attribute-level issues; it does not replace keyboard, screen reader, and manual UX testing.
