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 | $0.00213 | $0.02402 |
| Opus 5 | $0.00106 | $0.01201 |
| Sonnet 5 | $0.00043 | $0.00480 |
| Haiku 4.5 | $0.00021 | $0.00240 |
Grade A, and why
merit-vat-kmd 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.
How it starts
The opening of the file, as written. The whole thing — 159 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Merit VAT & KMD (käibedeklaratsioon)
Scope: this skill describes the Estonian VAT regime (KMS, EMTA, the KMD return, the 24% standard rate). On the Polish localization (
360 Księgowość) the VAT rules, rates, and return differ — use the CLI's tax/account mechanics here, but apply your local Polish VAT rules rather than the EE specifics below.
How Merit computes VAT and produces the monthly KMD, and how to support it from
elnora-merit. The API has no KMD endpoint — Merit builds and files the KMD in the
UI from the invoices you enter. The CLI's job is to get the per-line VAT right and to pull
the figures that verify it.
Get the VAT codes (TaxId guids + rates) from the company profile (
elnora-merit profile sync→company-profile.json;profile show --section taxes). Filing cadence and standing VAT rules come from your prose books reference if you keep one. Load what applies before relying on this.
How the KMD is built (the one mental model)
Merit auto-fills the KMD from every saved sales and purchase invoice. The VAT
code (TaxId) on each invoice line routes that line's amounts to the correct KMD row.
You never type figures into the KMD. So a correct KMD is entirely a function of:
- The right
TaxIdon every invoice line (taxes list→ the guid), and - Every invoice for the period entered before the KMD is generated.
Get the line codes right and the declaration is right. Fix a wrong KMD by fixing the source invoice's code/date/amount, not the declaration.
The tax codes
elnora-merit taxes list # [{ Id (guid), Code "24%", Name, TaxPct }]
- The Estonian standard rate is 24% from 01.07.2025 (was 22%, earlier 20%). Use the
Idof the current standard-rate row on standard domestic supply. - VAT codes are bound to specific built-in GL accounts. When a new code is genuinely needed it's added in the UI (Settings → Finance → Käibemaks) — do not invent GL accounts for it; Merit assigns them.
taxes createexists but is documented only for OSS codes (--tax-type 12). Adding everyday rates is a UI task.
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.

merit-vat-kmd is a skill published in the GitHub repository Elnora-AI/elnora-merit-aktiva (8 stars, last pushed 5d ago), licensed Apache-2.0. It adds 213 tokens to every session and 2,402 once invoked, about $0.0011 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
