Markdown instructions
A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.
Works with any LLM
AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.
Self-contained
Everything the model needs lives in the instructions — no extra files to sync.
Open source
Published by WellApp-ai on GitHub. Read the source before you install it.

Installation

Install the Vat Summary AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

Open the app and go to Plugins → Skills.
Choose "Install from GitHub".
Paste the skill folder URL below and confirm.
Enable the skill in any chat where you want it available.

Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills

git clone --depth 1 https://github.com/WellApp-ai/Well.git /tmp/Well
mkdir -p .claude/skills
cp -r /tmp/Well/plugins/well/skills/vat-summary .claude/skills/vat-summary

Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Vat Summary in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Vat Summary on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Vat Summary is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

Loaded only when it is needed
The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.
Switch models mid-chat
Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

VAT summary from Well

A VAT return is a byproduct of closed books, not a separate project. If the ledger is posted and correct, the figures already exist — the work is presentation. Work backward from the filing deadline and forward from the posted ledger, and surface uncertainty rather than reporting a number you're not sure of.

Build it from the posted ledger + tax rates

Discover the schema first (see well:querying-well-data).
Output VAT (collected on sales) — from issued invoices / invoice_items and their tax_rates, or the corresponding VAT ledger_accounts / journal_entries for the period. Group by rate (standard / reduced / zero / exempt).
Input VAT (paid on purchases) — from received invoices / invoice_items + tax_rates, or the input-VAT ledger accounts.
Net VAT due = output VAT − recoverable input VAT, per the period's date filter.
By rate and jurisdiction — break the totals down by VAT rate and, for multi-jurisdiction workspaces, by jurisdiction. Read the rate from the data (tax_rates), don't assume it.

Rules — conservative by design

"The books are not closed yet." If the period's journal_entries are still DRAFT / unposted, say so before producing a final figure — declarations fall out of closed books. Offer a provisional figure clearly labelled as such.
Surface uncertainty, don't file it. Where a rate, exemption, or jurisdiction treatment is ambiguous, flag it for human review rather than guessing.
Read rates and jurisdictions from tax_rates / the data; never hardcode a percentage.
Don't sum across currencies without converting (exchange_rates).

Present it

Output VAT (by rate) → total; Input VAT (by rate) → total; Net VAT due; the period and jurisdiction; a books-closed/draft status line; and any flagged uncertainties for review.

Frequently asked questions

What does the Vat Summary AI skill do?

Why use Vat Summary on TypingMind?

Because you install it once and use it with any model. Vat Summary is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Vat Summary in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/WellApp-ai/Well/tree/main/plugins/well/skills/vat-summary. TypingMind reads its SKILL.md and installs it as a skill you can enable per chat.

Which AI models can use Vat Summary?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Vat Summary?

As many as you like. As long as a model supports skills, you can use Vat Summary with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Vat Summary AI skill free?

Yes. It is published on GitHub by WellApp-ai under the MIT license. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
