Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00076 | $0.02843 |
| Opus 5 | $0.00038 | $0.01422 |
| Sonnet 5 | $0.00015 | $0.00569 |
| Haiku 4.5 | $0.00008 | $0.00284 |
Grade A, and why
frontend-dev-guidelines 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 5d ago.
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.
This is a copy
95% identical to frontend-dev-guidelines — 7 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Frontend Development Guidelines
Purpose
Comprehensive guide for modern React development, emphasizing Suspense-based data fetching, lazy loading, proper file organization, and performance optimization.
When to Use This Skill
- Creating new components or pages
- Building new features
- Fetching data with TanStack Query
- Setting up routing with TanStack Router
- Styling components with MUI v7
- Performance optimization
- Organizing frontend code
- TypeScript best practices
Quick Start
New Component Checklist
Creating a component? Follow this checklist:
- Use
React.FC<Props>pattern with TypeScript - Lazy load if heavy component:
React.lazy(() => import()) - Wrap in
<SuspenseLoader>for loading states - Use
useSuspenseQueryfor data fetching - Import aliases:
@/,~types,~components,~features - Styles: Inline if <100 lines, separate file if >100 lines
- Use
useCallbackfor event handlers passed to children - Default export at bottom
- No early returns with loading spinners
- Use
useMuiSnackbarfor user notifications
New Feature Checklist
Creating a feature? Set up this structure:
- Create
features/{feature-name}/directory - Create subdirectories:
api/,components/,hooks/,helpers/,types/ - Create API service file:
api/{feature}Api.ts - Set up TypeScript types in
types/ - Create route in
routes/{feature-name}/index.tsx - Lazy load feature components
- Use Suspense boundaries
- Export public API from feature
index.ts
Import Aliases Quick Reference
| Alias | Resolves To | Example |
|---|---|---|
@/ |
src/ |
import { apiClient } from '@/lib/apiClient' |
~types |
src/types |
import type { User } from '~types/user' |
~components |
src/components |
import { SuspenseLoader } from '~components/SuspenseLoader' |
~features |
src/features |
import { authApi } from '~features/auth' |

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.

frontend-dev-guidelines is a skill published in the GitHub repository VoDaiLocz/kilo-kit-mcp (26 stars, last pushed yesterday), licensed Apache-2.0. It adds 76 tokens to every session and 2,843 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. It is 95% identical to frontend-dev-guidelines, differing in 7 lines, and is treated as a copy.
