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

monthly-close-checklist-and-reconciliation-prep 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.

Monthly Close Checklist and Reconciliation Prep

This skill turns a pasted transaction list or bank export (CSV rows or markdown table) plus a brief business context into three ready-to-use artifacts: a monthly-close checklist, a categorization draft with disputed flags, and an accountant/investor-ready summary — no accounting SaaS or integrations required.

Input:

  • Transaction list: CSV rows or markdown table (minimum columns: date, counterparty/description, amount)
  • Business context: entity type (ИП / ООО / sole-prop), primary currency, brief description of revenue model

Output:

  • Artifact 1 — Monthly-Close Checklist (locale-adapted)
  • Artifact 2 — Categorization Draft with Disputed Flags
  • Artifact 3 — Accountant Snapshot + Investor Narrative

Language Detection

Detect the user's language from their message:

  • If Russian (or contains Cyrillic): respond in Russian
  • If English (or other Latin-script language): respond in English
  • If ambiguous: respond in the language of the trigger phrase used

Instructions

Step 1: Validate Input

  1. Check that a transaction list is present in the user's message (CSV rows, markdown table, or plain list with date + counterparty + amount)

    • If no transaction list detected: stop. Return bilingual prompt:

      "Для работы нужен список транзакций — вставьте CSV-строки или таблицу в формате Markdown. / I need a transaction list — paste CSV rows or a Markdown table."

  2. Check that at least one parseable data row exists (not just headers or empty rows)

    • If zero data rows found: stop. Return in user's language:

      "Список не содержит транзакций. Убедитесь, что данные включают хотя бы одну строку с датой, контрагентом и суммой. / The list contains no transactions. Include at least one row with date, counterparty, and amount."

  3. Note any missing business context (entity type, currency, revenue model)

    • If absent: proceed with generic international defaults; note assumptions in the output preamble

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.
