previdencia-brasil

previdencia-brasil is a skill for Claude Code, Codex from AlissonSantos1/brasil-legal-skills. It costs 88 tokens per session (1,987 once invoked), scanned A, original, MIT.

An educational guide to Brazil’s INSS social-security system, which funds retirement and other benefits. It covers contributions, retirement rules, sickness benefits, maternity pay, survivor pensions, and the BPC benefit.

In plain words
What is it for?
Use it to estimate INSS contributions, compare employee, MEI, and self-employed options, examine retirement eligibility, and understand questions about sickness, maternity, disability, survivor, or BPC benefits.
Why use it?
Eligibility and contribution amounts depend on employment status, age, contribution history, and the benefit requested. This helps organize the rules and calculations, while personalized planning may require a specialist lawyer.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

previdencia-brasil 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 12d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/aposentadoria_estimativa.py, scripts/planejamento_contributivo.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
