audit-frontend

A check for common problems in frontend code, meaning the part of an application that users see and interact with. It looks for fixed sample values, placeholder images, mock data, debug logging, unused imports, weak TypeScript settings, and accessibility issues.

In plain words
What is it for?
Use it to inspect React, Vue, Svelte, Angular, or TypeScript frontend projects for code-quality and interface-pattern issues.
Why use it?
Temporary examples and debug code can accidentally reach production, while inconsistent styling and accessibility problems can harm users and maintenance.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

audit-frontend scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

The opening of the file, as written. The whole thing — 93 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Frontend Audit

Audit frontend source code for code quality issues, hardcoded values, dead code, and pattern violations.

Detection Strategy

Auto-detect frontend projects by scanning for:

  • package.json with React/Vue/Svelte/Angular dependencies
  • tsconfig.json for TypeScript projects
  • src/ directory structure

Identify all frontend directories (there may be multiple — e.g., user-facing app + admin panel).

Checks

1. Hardcoded Values in State

Grep useState.*["'][A-Z]|useState.*["'][a-z]{3,} for hardcoded initial state values. FAIL if personal data (names, emails, phone numbers) used as defaults — should come from API/props.

2. Placeholder Image URLs

Grep unsplash\.com|picsum\.photos|pravatar\.cc|placeholder\.com|placehold\.co|via\.placeholder. FAIL if used as production defaults without API fallback.

3. Mock Data in Production Code

Grep MOCK_|mockData|mock://|const mock[A-Z] in page/component files (NOT in dedicated test/mock files). FAIL for mock arrays or objects in production page components.

4. console.log/debug/info

Grep console\.(log|debug|info) in source files. Exclude console.error and console.warn. WARN with file count and locations.

5. TypeScript Strict Compliance

Run npx tsc --noEmit in each frontend project directory. FAIL for any type errors. Also grep for as any|: any — WARN with count (indicates type safety gaps).

6. Dead Imports

Grep for imports from files that no longer exist:

# Check for broken imports by running TypeScript compiler
npx tsc --noEmit 2>&1 | grep "Cannot find module"

FAIL if importing deleted or non-existent files.

7. Design Token Compliance

Grep #[0-9a-fA-F]{3,8} in component/page files (NOT in token/theme definition files). WARN for hardcoded color values that should reference design tokens. Also check for hardcoded spacing (margin:\s*[0-9]+px|padding:\s*[0-9]+px) outside utility classes.

8. Query Key Centralization

If using TanStack Query/React Query, grep useQuery.*queryKey:\s*\[['"] for inline string array keys. WARN if not using a centralized query key factory.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
