Cursor rules for Netlify development with official integration is a skill for Claude Code, Codex from AmariahAK/atlarix-skills. It costs 9 tokens per session (9,147 once invoked), scanned C, original, Apache-2.0.

A set of coding rules for Netlify, a platform that hosts websites and runs serverless, edge, background, and scheduled functions. It covers local development, configuration, CORS, imports, and deployment-related files.

In plain words
What is it for?
Use it when building or maintaining Netlify sites and functions, including serverless APIs, edge request handling, background jobs, and scheduled tasks.
Why use it?
It helps avoid common Netlify setup mistakes, such as committing the .netlify folder, adding unwanted CORS headers, or using the wrong local development command.

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 C, and why

Cursor rules for Netlify development with official integration scanned grade C with 1 finding 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 9d 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.

Directives inside HTML comments, invisible characters or bidirectional overrides are read by the model and not by the person reviewing the file.

ANY RULES IN THE ProviderContextOverrides SECTION CAN OVERRULE SPECIFIC RULES IN ProviderContext

  • the .netlify folder is not for user code. It should be added to the .gitignore list
  • avoid adding version numbers to imported code. (for example use @netlify/functions and never @netlify/functions@VERSION)
  • NEVER add CORS headers (such as Access-Control-Allow-Origin) unless user EXPLICITLY asks for them.
  • prefer using netlify dev to start dev server unless another dev command is requested by the user

Guidelines

  • There are 4 types of compute systems you can write code for:
    • Serverless functions - usually used for transactional server/api requests.
    • Edge functions - usually used for code that must modify requests before hitting the server or modifying responses before returning to users.
    • Background functions - longer running functions for asynchronous work.
    • Scheduled functions - schedule logic to run on a CRON-based interval.
  • Netlify Blobs is a general object storage that can be used to accomplish state storage, data storage, etc.
  • Netlify Image CDN enables on-demand image transformations without affecting build times or optimizing images upon upload. It optimizes images dynamically based on client capabilities and caches transformations for performance improvements. Use this when optimizing images dynamically. Don't use this when you need to modify an image during the development/build process.
  • Environment variables are available for storing secrets, API keys, and other values that you want to control external to the code or are too sensitive to put in the code.

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.
