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 | $0.00202 | $0.01239 |
| Opus 5 | $0.00101 | $0.00620 |
| Sonnet 5 | $0.00040 | $0.00248 |
| Haiku 4.5 | $0.00020 | $0.00124 |
Grade A, and why
merit-reverse-charge 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.

Merit Reverse-Charge VAT
How to book reverse-charge VAT (pöördkäibemaks) in Merit Aktiva so it lands on the KMD correctly. Covers EU intra-community acquisitions of goods and services, plus reverse-charged services from non-EU suppliers.
The one thing to get right: reverse charge is driven by the VENDOR'S COUNTRY, not
by a VAT code. There is no "reverse-charge" tax code to select or create — that is
Envoice's model, not Merit's. Do not conflate them. taxes list confirms it: the
company has plain rate codes (24%, 22%, 9%…) and no reverse-charge code.
The rule
Set the vendor card's country correctly, leave the standard rate (24%) on the invoice lines, and Merit zeroes the payable VAT and self-assesses the reverse charge onto the KMD automatically.
| Supplier | Vendor card CountryCode |
Invoice line VAT | KMD lines (value / VAT) |
|---|---|---|---|
| EU, VAT-registered (e.g. an EU SaaS supplier registered in IE) | the EU country, not EE |
leave 24% | 1, 6, 6.1 / 4, 5 |
| EU service (no goods) | the EU country | leave 24% | 1, 6 / 4, 5 |
| Non-EU service, place of supply EE (e.g. a US SaaS vendor) | the non-EU country | leave 24% | 1, 7 / 4, 5 |
| EU supplier not VAT-registered | the EU country | set line to 0% | no reverse charge |
| Non-EU goods (cleared at customs) | the non-EU country | set line to 0% | import VAT via customs, not here |
Net VAT effect of a reverse charge is €0 when fully deductible (same amount on line 4 output and line 5 input) — but declaring it is mandatory.
What Merit does NOT do
Merit posts no general-ledger entry for the reverse charge — the GL records only net expense and net vendor payable. The self-assessment exists for the KMD alone. This is why the KMD's "Müügi käibemaks kokku" and "Sisendkäibemaks kokku" differ from the GL VAT account balances by exactly the reverse-charge amount. Expected, not an error.
Booking it (CLI)
A reverse-charge purchase is an ordinary purchase-invoices create with two things
right. Read reference/recipe.md for the full step-by-step,
the exact field values, and verification before posting.
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.
