Markdown instructions
A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.
Works with any LLM
AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.
2 bundled files
Scripts, templates, and references the model can read while it works. Files are read-only and never executed.
Open source
Published by HoangNguyen0403 on GitHub. Read the source before you install it.

Installation

Install the Angular Security AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

Open the app and go to Plugins → Skills.
Choose "Install from GitHub".
Paste the skill folder URL below and confirm.
Enable the skill in any chat where you want it available.

Add skills

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills

git clone --depth 1 https://github.com/HoangNguyen0403/agent-skills-standard.git /tmp/agent-skills-standard
mkdir -p .claude/skills
cp -r /tmp/agent-skills-standard/skills/angular/angular-security .claude/skills/angular-security

Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Angular Security in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Angular Security on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Angular Security is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

Loaded only when it is needed
The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.
Switch models mid-chat
Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

Security

Priority: P0 (CRITICAL)

Principles

XSS Prevention: Angular sanitizes interpolated values by default — {{ userInput }} safe. NOT use innerHTML unless absolutely necessary (e.g., trusted static CMS content). For user-generated content, display as text with {{ content }} — never as HTML.
Trusted HTML APIs: Mark HTML as trusted only for content you control (e.g., vetted CMS headers). Never mark user-provided data as trusted. Prefer DomSanitizer.sanitize(SecurityContext.HTML, content) and review every trust-marking call as a potential XSS vector.
Route Guards: Protect all sensitive routes with functional CanActivateFn (e.g., inject(Router).createUrlTree(['/login'])). Apply with canActivate: [authGuard].

Guidelines

CSP: Configure CSP headers on server (not in Angular source). Use nonce-based CSP with script-src 'nonce-{nonce}' and avoid unsafe-inline/unsafe-eval.
HTTP: Use Interceptors to attach secure tokens. Use HttpOnly cookies managed by server — not localStorage or sessionStorage because they accessible via XSS.
Secrets: Never store API keys or secrets in Angular source code or bundle.

Anti-Patterns

No trust-marking on user input: Trust Angular's sanitization; reserve trusted HTML APIs for verified static content only.
No localStorage for tokens: Use HttpOnly cookies via interceptors for auth tokens.
No secrets in source: Never embed API keys or secrets in Angular bundle code.

CSP and secret checklist

Use a server-generated, per-response nonce in script-src 'nonce-{nonce}'; do not use a static nonce.
Keep controlled provenance explicit: trust-mark only controlled and verified or vetted static CMS content.
Do not put API keys or other secrets in the compiled bundle.

Canonical response anchors

Additional task-grounded exact anchors: {{ content }}

Bundled files

The model reads these on demand while the skill is loaded. They are exposed as readable files and are never executed.

Frequently asked questions

What does the Angular Security AI skill do?

Harden Angular apps against XSS, CSP violations, and unauthorized access. Use when implementing XSS protection, Content Security Policy, or auth guards in Angular.

Why use Angular Security on TypingMind?

Because you install it once and use it with any model. Angular Security is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Angular Security in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/HoangNguyen0403/agent-skills-standard/tree/develop/skills/angular/angular-security. TypingMind reads its SKILL.md and bundles its files and installs it as a skill you can enable per chat.

Which AI models can use Angular Security?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Angular Security?

As many as you like. As long as a model supports skills, you can use Angular Security with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Angular Security AI skill free?

Yes. It is published on GitHub by HoangNguyen0403 under the MIT license. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
