Manage business clients - list, search, create, or update client information. Use when the user mentions clients, contacts, customers, Kunden, or needs to manage their client database.

The file

We split this skill into the rules it gives an agent

5 rules. About 0 are common, 1 is distinctive, and 4 are very specific to this project.

  • ≈0

    Common · estimate

    Many files like this have a rule of this kind.

  • ≈1

    Distinctive · estimate

    This author's own choices. Worth a look.

  • 4

    Very specific

    Tied to their project's names, files or tools. Probably skip.

  • Common
  • Distinctive
  • Very specific
  1. Very specific:

    Call list_clients to show all clients

    line 17
  2. Very specific:

    When creating a client with create_client, gather:

    line 21
  3. Very specific:

    Call get_client first to show current details

    line 29
  4. Very specific:

    Call update_client with only the fields that need changing

    line 30
  5. Distinctive:

    Always verify client details before creating invoices

    line 34

≈ “Common” is an estimate: at least 1 in 5 of the 350,495 skill files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

Help the user manage their client database:

Listing and searching

  • Call list_clients to show all clients
  • Present results in a clean table format: Name, Email, Phone, Outstanding balance

Creating a new client

When creating a client with create_client, gather:

  • Required: Client name (company or individual)
  • Recommended: Email, phone, address (street, city, postal code, country)
  • Optional: Tax ID (DE Steuernummer, PL NIP), EU VAT ID (DE USt-IdNr., PL NIP with the PL prefix), payment terms, notes
  • For German businesses: ask about Kleinunternehmer status if relevant
  • For Polish businesses: ask about the VAT exemption (zwolnienie podmiotowe z VAT) if relevant

Updating a client

  • Call get_client first to show current details
  • Call update_client with only the fields that need changing
  • Confirm changes with the user before updating

Best practices

  • Always verify client details before creating invoices
  • For EU business clients, their EU VAT ID is needed for reverse charge invoices, the German ZM and the Polish VAT-UE
  • Suggest cleaning up duplicate clients if detected

Does it work?

Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.

No reviews yet

People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.

  • It worked
  • Partly
  • It didn't
What did you use it for? e.g. Reviewing pull requests in a Rails app

Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.

Files you open will collect here, so you can find them again.

Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.

Now do this for your own.

Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
