Use stub safely with AI

Sets the rules for working in stub: confirms which business you are in, chooses between similar tools, and asks for your explicit yes before anything in your books changes.

Use it when

You are starting any stub task and want the assistant to check the business scope first
You want to know which stub actions the assistant will only propose and never apply on its own
An assistant is about to create, edit or delete records and you want to review the exact change first

Tools it uses

delete_clients_bulk
create_income_expenses_bulk
add_document_line
add_journal_line
add_salestax_to_entities
add_entity_salestax
add_entity_salestaxes
add_document_item_salestax
create_account
create_asset
create_bank_account
create_folder
create_tag
attach_file
clear_entity_tags
delete_client
delete_document
delete_document_line
delete_expense
delete_income
delete_journal_entry
delete_message
delete_product
delete_supplier

Example

Before you touch anything in stub, confirm which business we are working in and list the unpaid invoices from last month.

You are working in Acme Studio. I checked invoices dated last month with status unpaid: 12 records on one page, and the list is complete. Nothing has been changed. Tell me if you want any of them updated.

Clean up your customers and suppliers in stub

Finds duplicate, stale and incomplete client and supplier records, checks what each one is linked to, and prepares a change list. Nothing is merged or deleted until you approve it.

Use it when

Your customer list has the same company entered twice
You want to archive old suppliers without losing open bills
You need supplier and client details filled in before year end

Tools it uses

delete_document
delete_document_line
delete_client
delete_clients_bulk
add_entity_salestax
add_entity_salestaxes
delete_supplier

Example

Find duplicate and stale clients in my stub account and suggest what to merge or archive.

I reviewed 214 clients across 3 pages. I found 17 likely duplicates: 11 are strong matches on tax number, and 6 are name-only matches I've flagged as questions. Before any merge, I checked each record's invoices and balances. Nothing has been changed yet; reply with approval for each group.

Prepare your VAT or sales tax return summary

Gathers the tax figures for a period, checks the rate on every invoice and bill, and produces a reconciliation for your review. It asks before changing any document and never files anything.

Use it when

You need to prepare your VAT or sales tax for the quarter
You want to check that invoices carried the right tax before you file
You want to know roughly what you owe or can reclaim for a period

Tools it uses

add_entity_salestax
add_entity_salestaxes
add_document_line
add_document_item_salestax

Example

Prepare my sales tax summary for the quarter ending 31 March and tell me what I need to fix first.

Output tax is 12,400 from 186 invoices and credit notes, and input tax is 4,150 from 97 bills, so you owe a net 8,250. Three invoices to one customer have no tax code and would add about 620 if corrected. I have not changed anything; send me the yes and I will apply the fixes.

Reconcile your bank transactions

Matches your stub bank feed lines to income and expense records, flags unmatched items, duplicates and transfers, and proposes categories. It asks before changing any entry.

Use it when

Your bank feed has lines that are not yet recorded in stub
You want to check the books agree with the bank statement for the month
You suspect a payment was imported twice

Tools it uses

create_bank_account
add_journal_line
create_income_expenses_bulk
delete_income
delete_expense
add_entity_salestax
add_document_item_salestax

Example

Reconcile my main current account for March and tell me what doesn't match.

Your March feed has 142 lines totalling 58,420.00 and there are 139 income and expense entries. 131 match exactly. Of the 11 unmatched bank lines, 6 look like card settlements that cover several sales, and 5 need a category. I found one likely duplicate: a 1,250.00 supplier payment imported twice on 14 March. Nothing has been changed yet.

Review invoices and quotes in stub

Audits your open invoices, quotes and credit notes for overdue, mismatched or incomplete documents, then drafts follow-ups for your approval. Nothing is sent or changed without your say.

Use it when

Month-end, when you want to know what customers owe you
Before chasing payments, to rule out invoices that are already paid
When credit notes or old quotes may have been left unapplied

Tools it uses

add_document_line
delete_document_line
add_document_item_salestax
add_entity_salestax
add_salestax_to_entities
delete_document

Example

Review my open invoices as at today and tell me what needs chasing.

Of 38 open invoices totalling 214,500, 11 are overdue for 41,800 in total. Six of those are between 31 and 60 days old, and the largest is an invoice to Kestrel Trading for 12,400, now 47 days late. Two credit notes totalling 3,200 have not been applied against anything. I have drafted reminders for the six clearest cases and have sent none; tell me which to send.

How stub skills work

Connect stub
The stub MCP server gives the agent its tools.
Ask in plain words
“Find duplicate and stale clients in my stub account and suggest what to merge or archive.” Each SKILL.md says when it applies, so only the one that fits is loaded.
Approve any change
The agent calls the tools in order, checks its work, and shows you any change before it makes it.

How to install stub skills

In RevampKey the skills install themselves when you connect stub. In other tools each skill is one folder with a SKILL.md file, and you also need the stub MCP server connected there.

stub skills FAQ

What is a stub agent skill?

A SKILL.md file: a short playbook an AI agent loads when your request matches it. Each stub skill describes one job, which stub tools to use in which order, what to check first and when to stop and ask you.

Do the stub skills change anything on their own?

The others tell the agent to show you the change and wait for a yes before it creates, edits or deletes anything in stub.

Which tools can use these skills?

Any agent that reads the open Agent Skills format: Claude Code, Cursor, Codex, VS Code with Copilot and RevampKey. In RevampKey they are attached when you connect stub; elsewhere you copy the folders into your project or skills directory.

Do I need the stub MCP server too?

Yes. The skills tell the agent how to do the work; the stub MCP server gives it the tools to do it. The stub MCP setup guide covers every client.
