Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00120 | $0.00749 |
| Opus 5 | $0.00060 | $0.00375 |
| Sonnet 5 | $0.00024 | $0.00150 |
| Haiku 4.5 | $0.00012 | $0.00075 |
Grade A, and why
ley-ar scanned grade A with 0 findings 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 13d 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.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 79 lines — stays where its author put it; the contents beside it link to each section on GitHub.
ley-ar — Argentine Legal Database Search
Search jurisprudence, legislation, and doctrine from 4 public Argentine legal databases.
Installation
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
# 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
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.

ley-ar is a skill published in the GitHub repository ThomasMoreAI/legal-skills-open (72 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 120 tokens to every session and 749 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 0 findings.
