zus-dra

zus-dra is a skill for Claude Code from dithiothreitol/jdg-ksiegowy. It costs 113 tokens per session (629 once invoked), scanned A, original, MIT.

A generator for Poland's ZUS DRA monthly declaration for a sole trader. ZUS is Poland's social-insurance institution, and the generated XML file can be imported manually into its PUE online portal.

In plain words
What is it for?
Use it to calculate the applicable health contribution, optionally include social contributions, generate a KEDU XML file, and check the filing deadline.
Why use it?
It calculates the health-insurance contribution from the previous year's revenue and prepares the declaration file. This avoids entering the same declaration data by hand, while still requiring manual import.

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

zus-dra 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 11d 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.

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.
