expenses-and-vendors

expenses-and-vendors is a skill for Claude Code from Frihet-io/frihet-mcp. It costs 86 tokens per session (1,672 once invoked), scanned A, original, MIT.

A business-record tool for managing expenses and vendors in a connected Frihet workspace. It can list and inspect records and, with confirmation, create or update them.

In plain words
What is it for?
Use it to filter expenses by date, category, or vendor, inspect expense details, and list, create, or update vendor records.
Why use it?
It keeps spending and supplier information organized and distinguishes proposed accounting changes from authorized changes. This makes it easier to review expenses without editing records accidentally.

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

expenses-and-vendors 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 2d 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.

Expenses & Vendors (expenses-and-vendors)

Respond in the user's language (English or Spanish). Keep expense proposals and accounting questions distinct from authorized changes in Frihet.

Supported tools in this workflow

  • Expenses (read-only): list_expenses, get_expense
  • Expenses (write, requires confirm: true): create_expense, update_expense
  • Vendors (read-only): list_vendors, get_vendor
  • Vendors (write, requires confirm: true): create_vendor, update_vendor

1. Reviewing expenses and vendors

  1. Expense queries:
    • Call list_expenses with optional filters (from, to, category, vendorId, limit, offset, after).
    • Call get_expense (id) when the user needs full detail on a specific expense (including stored paidDate, taxDeductible, vendor, and vendorId).
  2. Vendor queries:
    • Call list_vendors (limit, offset, after) and get_vendor (id) to inspect supplier records (id, name, email, phone).
    • Dedicated government-identifier fields (NIF/CIF/VAT) and precise street addresses are intentionally omitted from the reviewed vendor DTOs.
  3. Pagination truth (exploratory single-page default vs. exhaustive requests):
    • Always check total, limit, offset, and nextCursor on list_expenses and list_vendors.
    • Never present a single page as the complete set of expenses or vendors when nextCursor is present or total > data.length. For general browsing, return the first page immediately and state clearly that the response is a partial page (e.g., Showing 20 of 65 expenses); when the user explicitly requests all records, a full sort, or an exact sum across all pages, paginate using after (nextCursor) or offset until all pages are retrieved (or until a clear safety limit is reached, disclosing the exact coverage).

2. Recording a new expense (create_expense)

  1. Required inputs & zero-invention rule:
    • create_expense requires four explicit business fields plus confirmation:
      • description (non-empty string)
      • amount (positive number, in the schema's monetary unit)
      • date (YYYY-MM-DD — determines the expense's accounting and future tax-report period)
      • taxDeductible (boolean — records an explicit internal tax-deductible classification without filing any return)
      • confirm: true
    • Optional fields: category, vendor (supplier name).
    • Never invent description, amount, date, or taxDeductible. Do not assume an expense is tax-deductible (taxDeductible: true) or non-deductible (false) by default, and do not guess the expense date or amount if the user did not state them. If any of description, amount, date, or taxDeductible is missing, do not call list_vendors, list_expenses, or get_business_context first—ask the user directly for only the specific required fields that are actually missing (for example, if the user already provided date and taxDeductible but omitted amount or description, ask only for the missing amount / description and confirmation without re-asking for date or taxDeductible) before calling create_expense.
  2. Authorization & lasting/external effects disclosure:
    • Before executing an unauthorized create_expense, disclose:
      • The date selects the accounting and future tax-report period (no tax return is filed, and the connector does not mark the expense paid).
      • When vendor is provided and no exact vendor match exists, Frihet may create and link the vendor in a separate backend step that can remain even if the subsequent expense write fails.
      • create_expense can deliver expense.created events to active owner-configured webhooks, notify eligible workspace admins or accountants in-app and via Novu, and award first-use referral activation credits.
    • Minimum necessary calls: Make the minimum calls needed to complete the user's task. When the user's prompt already supplies description, amount, date, and an explicit taxDeductible choice along with authorization to record the expense, call create_expense with confirm: true directly without asking a second confirmation question or performing redundant pre/post reads, unless a lookup (list_vendors / get_expense) is needed to disambiguate an incomplete input, verify an uncertain write outcome, or satisfy an explicit verification request.
  3. Post-creation reporting:
    • Report the new id, description, amount, date, taxDeductible, category / vendor / vendorId (when stored), and externalEffects. Do not claim the expense was paid, reimbursed, or filed with a tax authority.

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.
