What it does

Vat Summary is an agent skill from WellApp-ai/Well. Produce a VAT / sales-tax summary for a period from a Well workspace's posted ledger. Use when the user asks for a VAT return, VAT summary, sales tax owed, output vs input VAT, or tax declaration figures for a period.

Its SKILL.md is about 540 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Business, Finance & HR, covering Tax preparation and Forms and invoices. The repository describes itself as: No more Sundays on Finance. We build the infrastructure that retrieves, processes, and routes your financial and business data to your FinOps stack, so founders can ship, not… The licence is MIT.

When your agent uses it

  • The user asks for a VAT return
  • Output vs input VAT
  • Tax declaration figures for a period

Example prompts

  • “/vat-summary”

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. Discover the schema first (see well:querying-well-data).
  2. Output VAT (collected on sales) — from issued invoices / invoice_items and their tax_rates, or the corresponding VAT ledger_accounts /…
  3. Input VAT (paid on purchases) — from received invoices / invoice_items + tax_rates, or the input-VAT ledger accounts.
  4. Net VAT due = output VAT − recoverable input VAT, per the period's date filter.
  5. By rate and jurisdiction — break the totals down by VAT rate and, for multi-jurisdiction workspaces, by jurisdiction. Read the rate from…

What it can do on your machine

Read from SKILL.md and the folder at commit c740217. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Vat Summary loads about 535 tokens when it runs. Until then it costs about 57 tokens; SKILL.md has 267 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~57
When it runs · the whole SKILL.md, loaded when a task matches
~535

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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

  1. Discover the schema first (see well:querying-well-data).
  2. 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).
  3. Input VAT (paid on purchases) — from received invoices / invoice_items + tax_rates, or the input-VAT ledger accounts.
  4. Net VAT due = output VAT − recoverable input VAT, per the period's date filter.
  5. 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.
