juros

juros is a command for Claude Code from linofcp007/advogado-pt. It costs 25 tokens per session (269 once invoked), scanned A, original, MIT.

A calculator for default interest, meaning money added when a payment is late, under Portuguese commercial or civil rules. It calculates the amount between two dates from a principal sum.

In plain words
What is it for?
Use it to estimate late-payment interest by entering the principal, start date, optional end date, and interest type.
Why use it?
It avoids working out the time period, rate, interest, and total by hand. The result is an estimate for support, not a final legal calculation.

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

juros 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 8d 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.

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.
