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 | $0.00030 | $0.00379 |
| Opus 5 | $0.00015 | $0.00189 |
| Sonnet 5 | $0.00006 | $0.00076 |
| Haiku 4.5 | $0.00003 | $0.00038 |
Grade A, and why
poland-tax 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 it actually says
Poland Tax
Use for PIT and other official tax-process orientation, tax-year routing, NIP
questions, e-Tax Office, filing channels, tax-office appointments, and source
verification. Social-insurance contributions and eZUS belong to
poland-social-insurance.
Confirm tax year, income or activity categories without amounts, employment or business context, cross-border countries, stated deadline, and whether the user needs public guidance, a generic placeholder draft, or an official landing-page handoff. Do not collect identifiers, account data, tax records, or credentials in plugin tools.
Use current Ministry of Finance, podatki.gov.pl, and National Revenue Administration records. State the period, competent office or service, known assumptions, missing facts, freshness, and human action boundary. Do not decide tax residence, choose deductions, optimize tax, calculate liability from an incomplete case, or accept a tax declaration's truth for the user.
For requested e-Tax Office or filing assistance, apply
../../references/automation-playbook.md. The user authenticates, signs or
attests, and completes final payment authorization. Explicit task scope permits
minimum relevant record inspection and form filling; booking, correction,
server-side draft creation, payment initiation, upload, download, or submission
requires fresh action-time confirmation. Recheck calculated values and current
official rules before the checkpoint.
Route business formation to poland-business, ZUS to
poland-social-insurance, cross-border free movement to poland-eu-mobility,
and adverse decisions to poland-appeals-review. Read
../../references/work-tax-business.md.
What ships with it
1 file 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.
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.
