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.
65 bundled files
Scripts, templates, and references the model can read while it works. Files are read-only and never executed.
Open source
Published by transilienceai on GitHub. Read the source before you install it.

Installation

Install the Authentication 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.
https://github.com/transilienceai/communitytools/tree/main/skills/authentication
Enable the skill in any chat where you want it available.

Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.

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/transilienceai/communitytools.git /tmp/communitytools
mkdir -p .claude/skills
cp -r /tmp/communitytools/skills/authentication .claude/skills/authentication

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

Use it in TypingMind

Enable Authentication 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 Authentication 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 Authentication 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.

Authentication

Test authentication mechanisms including login security, token handling, 2FA, CAPTCHA, and bot detection.

Techniques

Type	Key Vectors
Auth Bypass	Default credentials, logic flaws, response manipulation
ADFS/SAML	Golden SAML, token signing cert theft, assertion manipulation, SAML wrapping
JWT	Algorithm confusion, key injection, claim tampering, token forging
OAuth	Redirect manipulation, CSRF, token leakage, scope abuse
Password	Brute force, credential stuffing, password policy bypass
2FA Bypass	Response manipulation, direct endpoint access, code reuse, race conditions
CAPTCHA Bypass	Missing server validation, token reuse, OCR, parameter manipulation
Bot Detection	Behavioral biometrics simulation, fingerprint randomization, stealth mode

Tools

PasswordGenerator (tools/password_generator.py):

python
from tools.password_generator import generate_password
password = generate_password(hint_text="8-16 chars, uppercase, numbers")

CredentialManager (tools/credential_manager.py):

python
from tools.credential_manager import CredentialManager
mgr = CredentialManager()
mgr.store_credential(target="example.com", username="test", password="pass")

Workflow

Analyze auth implementation (forms, tokens, 2FA, CAPTCHA)
Test bypass vectors per technique type
Use Playwright MCP with human-like behavior (typing 80-200ms, random pauses)
Capture evidence (screenshots, network logs, tokens)
Document findings with PoC scripts

Frequently asked questions

What does the Authentication AI skill do?

Authentication security testing - auth bypass, JWT attacks, OAuth flaws, password attacks, 2FA bypass, CAPTCHA bypass, and bot detection evasion.

Why use Authentication on TypingMind?

Because you install it once and use it with any model. Authentication 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 Authentication in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/transilienceai/communitytools/tree/main/skills/authentication. 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 Authentication?

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 Authentication?

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

Is the Authentication AI skill free?

Yes. It is published on GitHub by transilienceai 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.
