Test it

Using "typescript-strict-guard". A React form component uses broad event types and unsafe assertions.

Expected outcome:

Lists the unsafe event and assertion patterns.
Recommends exact React event types and nullable state handling.
Explains how the changes satisfy strict mode.

Using "typescript-strict-guard". An API client returns unknown data without validation.

Expected outcome:

Defines the expected domain shape in plain terms.
Suggests runtime guards before returning typed values.
Adds error handling guidance for invalid responses.

Using "typescript-strict-guard". A project wants a pre-commit TypeScript sanity check.

Expected outcome:

Explains which validator checks apply.
Shows when to run the validator during review.
Notes that compiler and linter checks are still required.

Security Audit

Safe

v8 • 7/6/2026 Open versioned report

Static analysis flagged many patterns because this skill is documentation-heavy and includes TypeScript examples. Manual review found the backticks, fetch calls, environment variable names, and file paths are examples or validator messages, not malicious runtime behavior. No prompt-injection attempt or exfiltration intent was found.

What You Can Build

Review generated TypeScript

Find strict mode problems before generated code reaches a pull request.

Standardize React typing

Apply consistent props, event, hook, and form patterns across React components.

Harden external data handling

Replace unsafe casts with type guards, assertions, and runtime validation patterns.

Try These Prompts

Check strict mode basics

Review this TypeScript file for strict mode issues. Identify unsafe any, @ts-ignore, non-null assertions, and missing return types.

Improve React typings

Refactor this React TypeScript code to use explicit props, typed events, safe refs, and precise hook return types.

Design runtime guards

Create type guards and assertion helpers for this external data shape. Avoid unsafe casts and explain each narrowing step.

Audit a TypeScript workflow

Audit this TypeScript workflow for strict mode gaps, async error typing, third-party type boundaries, and validator coverage.

Best Practices

Use the guide before generating TypeScript that touches external data or React state.
Run the validator on changed files, then confirm results with TypeScript and project lint rules.
Prefer unknown plus type guards when data crosses a trust boundary.
