bukio-cli

bukio-cli is a skill for Claude Code, Codex from erikvankempen/bukio-cli. It costs 32 tokens per session (1,203 once invoked), scanned A, original, Apache-2.0.

An agent workflow for bukio-cli, a bookkeeping tool for small and medium-sized businesses in eleven countries. It records invoices, stores their original files, and checks that the accounting records remain balanced.

In plain words
What is it for?
Use it to record purchase and sales invoices, import and match bank transactions, read VAT information, and check the books at month-end. It also supports other ledger changes such as reversals, assets, and amounts owed.
Why use it?
Manual bookkeeping can lose source documents or create unbalanced records. This workflow adds required checks and rules around recording transactions and closing a month.

Token cost

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.

Security

Grade A, and why

bukio-cli 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 3d 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.

bukio-cli — agent workflow

Full manual: AGENTS.md (house rules, JSON contracts, account codes, error codes, anti-patterns). This skill is the agent-facing workflow for the two things you'll do most: booking documents and keeping the books verifiable.

When to use

  • User sends an invoice PDF/photo/scan: "book this", "hoe boek ik dit?"
  • Register an inkoopfactuur (purchase) or verkoopfactuur (sale)
  • Month-end: bank import → match → VAT readout, or the month-end close check
  • Any mutation of the ledger (entry, reversal, VAT, assets, payables)

Environment

What How
DB --db <path> or BUKIO_DB (default ~/.bukio/bukio.db)
Actor --actor '<role>:<name>' or BUKIO_ACTOR — required (e.g. agent:bartholomeus)
JSON --json on every command; exit 0 = success, 1 = failure
Verify after any mutation: bukio report trial-balance --jsondata.balanced === true

House rules (non-negotiable): dry-run every mutation first · never touch the SQLite file directly · never delete posted entries (reverse instead) · money is integer cents · archive every source document (see below).

Booking an invoice (the core loop)

  1. Extract — read the invoice text (OCR for scans/images). Recompute the VAT: vat = round(net × rate) per rate, gross = net + vat. If the stated VAT differs beyond rounding, STOP and ask.
  2. Map — account from the chart (defaults: 4000 goods, 4340 software/SaaS, 4300 kantoor/general, 4310 accountant, 4320 insurance, 1800 equipment

    €450, 4500 bank charges; sales → 8000/8100), VAT code (21/9/0/V/R/RE/marge), counter leg (1100 bank if paid, 2000 crediteuren if unpaid, 1200 debiteuren for sales).

  3. Book — VAT module on → bukio vat book --postings "4300:100.00@21,1100:-121.00" --post (never hand-build VAT legs with entry add). VAT off/KOR → gross to the expense account, no VAT legs. Always --dry-run first, always --actor.
  4. Archive the original (mandatory) — before finishing:

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.
