Ley Ar

Organization

NeverSight

ley-ar

Search Argentine legal databases (SAIJ, JUBA, CSJN, JUSCABA) for jurisprudence, legislation, case summaries, and doctrine using the `ley` CLI. Use when the user asks about Argentine law, court decisions, legal precedents, fallos, jurisprudencia, legislación, or mentions SAIJ, JUBA, CSJN, JUSCABA. Supports parallel search across databases, JSON/table/text output, and filtering by jurisdiction. Built from reverse-engineered MCP servers (hernan-cc) — direct HTTP calls, no MCP layer needed.

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

Installation

Install the Ley Ar 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.

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/NeverSight/learn-skills.dev.git /tmp/learn-skills.dev
mkdir -p .claude/skills
cp -r /tmp/learn-skills.dev/data/skills-md/0juano/agent-skills/ley-ar .claude/skills/ley-ar

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

Use it in TypingMind

Enable Ley Ar 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 Ley Ar 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 Ley Ar 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.

ley-ar — Argentine Legal Database Search

Search jurisprudence, legislation, and doctrine from 4 public Argentine legal databases.

Installation

bash
cd {baseDir}/scripts && pip install -e . --break-system-packages -q

Requires Python 3.10+. Dependencies: typer, httpx, rich.

Databases

DB	Source	Best For	Reliability
`saij`	saij.gob.ar	National jurisprudence, legislation, doctrine	✅ Clean JSON API
`csjn`	sjconsulta.csjn.gov.ar	Supreme Court summaries	✅ HTML+JSON
`juba`	juba.scba.gov.ar	Buenos Aires Province decisions	⚠️ HTML scraping
`juscaba`	eje.juscaba.gob.ar	CABA court cases/expedientes	⚠️ Poor free-text

Default strategy: Start with --db saij,csjn. Add juba only for PBA-specific queries. Use juscaba only with case IDs.

Commands

bash
# Search all databases (parallel)
ley search "prescripción adquisitiva"

# Filter by database(s)
ley search "daño moral" --db saij,csjn

# Limit results
ley search "phishing bancario" --db saij --limit 5

# JSON output for scripting
ley search "responsabilidad civil" --db csjn --json

# Plain text
ley search "contrato de locación" --text

# Status check
ley status
ley --version

Search Tips

Use legal terminology: "daños y perjuicios" not "accidente de auto"
Be specific: "prescripción adquisitiva inmueble" > "prescripción"
"Patentes" ambiguity: returns IP patents, not vehicle tax. Use "impuesto automotor" or "radicación automotor" instead.
For current tax rates or alícuotas, use web search — these databases index case law, not regulatory info.

Output

Each result: db, id, title, date, snippet, url. Default: Rich table. --json for structured data.

Limitations

JUBA depends on ASP.NET WebForms scraping — breaks if site changes
CSJN full case text may need reCAPTCHA (summaries work)
JUSCABA works best with case identifiers, not free-text
No auth required — all public APIs
Respect rate limits: avoid rapid-fire queries

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 Ley Ar AI skill do?

Why use Ley Ar on TypingMind?

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

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/NeverSight/learn-skills.dev/tree/main/data/skills-md/0juano/agent-skills/ley-ar. 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 Ley Ar?

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 Ley Ar?

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

Is the Ley Ar AI skill free?

It is published on GitHub by NeverSight. Check the repository for licensing terms. 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.
