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 | $0.00124 | $0.04680 |
| Opus 5 | $0.00062 | $0.02340 |
| Sonnet 5 | $0.00025 | $0.00936 |
| Haiku 4.5 | $0.00012 | $0.00468 |
Grade A, and why
exact-afletter-logica 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 — 483 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Exact Online Afletter-Logica
Identificeer onafgeletterde posten en voer aflettingen uit. Werkt generiek, zonder hardcoded grootboekcodes.
Welke tool wanneer
| Tool | Waarvoor |
|---|---|
read_operation |
Alle GET-queries: discovery, scans, regels opzoeken. Levert maximaal 60 records per aanroep. |
write_operation |
Afletteren via MatchSets (POST). Vereist confirmed: true. |
analyze_data |
Optioneel voor bulk-aggregaties. Alleen op Trial of Analytics, niet op Essentials. |
read_operation geeft maximaal 60 records terug. Op Bulk-endpoints pagineer je met de
page_token uit next_page.page_token van de vorige respons, niet met skip. Haal bij een
bulk-scan altijd alle pagina's op voordat je conclusies trekt: een afgekapte lijst laat posten
stil verdwijnen.
Zie references/query-patterns.md voor de analyze_data-varianten van deze queries en voor de BankEntryLines-lookup per entrynummer.
Twee Use Cases
| Use Case | Doel | Primaire methode |
|---|---|---|
| A: Bulk Scan | "Wat moet er nog verwerkt worden?" | Phase 0, read_operation of analyze_data |
| B: Specifieke Match | "Letter deze factuur af tegen die betaling" | Phase 1-2, read_operation plus write_operation op MatchSets |
Begin altijd met Phase 0 voor een totaaloverzicht. Ga pas naar Phase 1-2 als je specifieke posten wilt matchen.
Phase 0: Discovery & Overzichtsscan
Standaard aanpak: read_operation. Werkt altijd, real-time data, geen extra abonnement vereist.
analyze_data is optioneel voor bulk-aggregaties over grote datasets, vereist Analytics of Trial
en kan mid-sync incomplete data bevatten.
Stap 0.1: Ontdek grootboekrekeningen (ALTIJD EERST)
Grootboekcodes verschillen per administratie. Gebruik het Type veld op GLAccounts om de juiste rekeningen te vinden:
Tool: read_operation
{
"service": "Financial",
"entity": "GLAccounts",
"filters": {"Type": [10, 12, 20, 22]},
"select": "Code,Description,Type,TypeDescription,BalanceSide"
}
What ships with it
2 files 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.
