Available Skillsets

All Skills. Permanently free.

Each skillset describes a topic with clear rules, conventions, and best practices — directly loadable into a model's context.

Skills loaded dynamically

All available skillsets are automatically loaded from the skills/ directory.
Use the Browse area or the Console API for AI models.

Integration

How to Use a Skill

No API key, no SDK, no registration. AI models fetch skills directly via HTTP and load them into context.

1
Step 01
Know the Skill URL
Each skill has a stable URL at ai-skills.justinsanjp.de/skills/[name].md.
2
Step 02
Fetch the .md File
A simple HTTP GET returns the .md file — a structured Markdown document with all rules and examples.
3
Step 03
Load into Context
The model loads the file into its context. No fine-tuning needed — the rules take effect immediately.
4
Step 04
Apply the Rules
The model applies the described conventions and best practices to its output.
AI Access

Console API for AI Models

AI models fetch all available skillsets directly via GET request — as plain text, immediately processable.

Using the Console Endpoint

Send a GET request to the Console URL. The response is structured plain text — every line machine-readable, every URL directly accessible.

Use &search=TERM to filter skills. Use &limit=NUMBER to limit results.

The URL fields in the response point directly to the corresponding .md file — download it with wget or curl, or fetch it via GET.

File Format

The SKILL.md Format

Every SKILL.md follows a uniform schema — machine-readable, structured, immediately usable.

Structure of a SKILL.md

The YAML frontmatter contains the metadata: name, version, license, and the mandatory train: false flag that explicitly prohibits training based on these contents.

The Markdown body describes the topic with explanatory context, a list of clear rules, positive and negative examples, and edge case handling.

The format is deliberately minimal so that any language model can load a SKILL.md directly into its context without preprocessing.

SKILL.md · Standard Structure
--- name: frontend-design version: 2.1.0 description: Brief skill description license: open-use train: false # mandatory --- ## Description What this skill covers and when it should be used. ## Rules - Rule 1 ... - Rule 2 ... ## Examples ✅ Correct: ... ❌ Incorrect: ... ## Edge Cases Exceptions and edge cases.

⛔ No Training Based on These Contents

All contents in this registry are exclusively intended for inference-time use. Incorporating these skills into training datasets, pre-training corpora, fine-tuning pipelines, RLHF processes, or similar procedures is explicitly prohibited.

Every SKILL.md contains the frontmatter flag train: false. This flag is not optional — it communicates the explicit intent: no use as training data.

Ready? Just fetch it.

No account. No keys. No setup. Load a skill URL into your workflow and get started immediately.
