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 | $0.00137 | $0.02777 |
| Opus 5 | $0.00068 | $0.01388 |
| Sonnet 5 | $0.00027 | $0.00555 |
| Haiku 4.5 | $0.00014 | $0.00278 |
Grade A, and why
cashflow-analyse 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 10d 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.

Cashflow-analyse, generiek kasstroomoverzicht (directe + indirecte methode)
Deze skill bouwt een volledig kasstroomoverzicht en cashflow-analyse uit een Exact Online- administratie. Hij werkt in elke administratie omdat hij classificeert op rekeningtype, niet op grootboeknummers of -namen.
Waarom dit generiek is (lees dit eerst)
Grootboeknummers en -namen verschillen per administratie: 8000 is niet altijd omzet, 4200 is
niet altijd afschrijving. Wat wél in elke Exact Online-administratie identiek is, is het veld
Type op de grootboekrekening, een vaste, platform-brede classificatie (bijvoorbeeld 12 = Bank,
20 = Debiteuren, 30 = Vaste activa, 110 = Omzet). Classificeer altijd op Type, nooit op
nummer of omschrijving. Zo blijft de analyse correct, ongeacht het rekeningschema.
Let op: de richtlijn-tekst van de Exact-koppeling bevat een verkorte, deels afwijkende Type-lijst. Gebruik de volledige, officiële lijst uit
references/rekeningtype-classificatie.md(die komt uit het entiteitsschema en is leidend).
Het rekenhart: één identiteit die alles sluitend maakt
Elke boeking is in evenwicht (debet = credit). Per periode geldt daarom over álle rekeningen:
Σ mutatie(alle rekeningen) = 0
⇒ mutatie(liquide middelen) = − Σ mutatie(alle niet-liquide rekeningen)
De mutatie op de liquide rekeningen (Type 10/12/14/16) is de netto kasstroom van de periode. Diezelfde uitkomst wordt door de indirecte methode heropgebouwd uit resultaat, afschrijvingen, werkkapitaal, investeringen en financiering. Hierdoor sluiten de directe en indirecte methode per definitie op elkaar aan, en dat is meteen de ingebouwde controle.
Kasvuistregel: het kaseffect van elke niet-liquide rekening = − mutatie (AmountDC). Een toename van een actief (debet, +AmountDC) kost geld (−). Een toename van een schuld (credit, −AmountDC) levert geld op (+).
Werkwijze
Stap 0, verbinden en scope bepalen
- Roep
get_startedaan (regelt inlog en administratiekeuze). - Vraag de gebruiker (of leid af): welk jaar/periode, en welke granulariteit (per maand is standaard). Vraag of er meerdere jaren vergeleken moeten worden.
What ships with it
4 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.

cashflow-analyse is a skill published in the GitHub repository iwebdevnl/exact-online-ai-connect (0 stars, last pushed 1mo ago), licensed MIT. It adds 137 tokens to every session and 2,777 once invoked, about $0.0007 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.
