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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00053 | $0.00580 |
| Opus 5 | $0.00026 | $0.00290 |
| Sonnet 5 | $0.00011 | $0.00116 |
| Haiku 4.5 | $0.00005 | $0.00058 |
Grade A, and why
ta-tax-compliance 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.
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
Perform a thorough tax compliance check for the tax advisor:
Step 1: Check compliance status
- Call
get_tax_compliance_statuswith the active company ID - This returns tax reports status, tax settings, and registration info
Step 2: Review tax settings
- Call
list_tax_settingsto verify the reporting frequency and VAT configuration - Check if the settings match the company type (e.g., Kleinunternehmer vs. VAT subject)
Step 3: Verify registration
Check the following registration details:
- Steuernummer (tax ID): Is it set? Is it in the correct format for the tax state?
- USt-IdNr. (VAT ID): Is it set? Is it needed based on EU trade activity?
- Tax state (Bundesland): Is it correctly assigned?
Step 4: Analyze report filing status
For each unfiled report:
- Identify the report type (USt-VA, EÜR, annual VAT, trade tax)
- Note the period and due date
- Flag if it is overdue
Step 5: Present the compliance report
Registration Status
- Tax ID: ✅/❌ with value if present
- VAT ID: ✅/❌ with value if present
- Tax state: ✅/❌ with name
Filing Status
| Report Type | Period | Status | Due Date |
|---|---|---|---|
| ... | ... | ... | ... |
Upcoming Deadlines
- List the next 3 filing deadlines with dates
- Note the standard deadlines:
- Monthly USt-VA: 10th of the following month (+ Dauerfristverlängerung = 10th of the month after)
- Quarterly USt-VA: 10th of the month after the quarter ends
- Annual USt: July 31 of the following year (with advisor extension: end of February of the year after)
Action Items
Prioritized list:
- Overdue reports that must be filed immediately
- Reports due within the next 30 days
- Registration issues that need attention
- Settings that may need adjustment
Be precise with dates and report periods. Use German tax terminology where appropriate.
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.
