What it does

Balance Sheet is an agent skill from WellApp-ai/Well. Build a balance sheet (bilan) from a Well workspace. Use when the user asks for a balance sheet, bilan, assets/liabilities/equity, or financial position at a point in time.

Its SKILL.md is about 530 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 Financial analysis. 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 balance sheet
  • Assets/liabilities/equity
  • Financial position at a point in time

Example prompts

  • “/balance-sheet”

Workflow steps

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

  1. Discover the schema (well:querying-well-data)
  2. As-of date: filter postings with date _lte (a balance sheet is cumulative from inception, not a period).
  3. Compute each account balance (sum of debits − credits, or read account_balances), then group by class
  4. Check it balances: total Actif must equal total Passif. If it doesn't, surface the gap rather than hiding it — it usually means unposted…

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

Balance Sheet loads about 534 tokens when it runs. Until then it costs about 47 tokens; SKILL.md has 250 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~47
When it runs · the whole SKILL.md, loaded when a task matches
~534

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.

Balance sheet (bilan) from Well

Like the P&L, the balance sheet comes from the posted ledger, not from raw documents. It is a point-in-time snapshot: balances of the balance-sheet accounts as of a date.

Do this

  1. Discover the schema (well:querying-well-data):
    • well_get_schema("ledger_accounts") — chart of accounts. Balance-sheet accounts are the asset/liability/equity classes (French plan comptable: classes 1–5; income-statement classes 6–7 are excluded).
    • well_get_schema("journal_entries") / journal_entry_lines — posted movements with debit/credit and dates.
    • well_get_schema("account_balances") — Well may expose computed balances directly; prefer these when present, they are the canonical balance per account.
  2. As-of date: filter postings with date _lte <as_of> (a balance sheet is cumulative from inception, not a period).
  3. Compute each account balance (sum of debits − credits, or read account_balances), then group by class:
    • Actif (assets): debit-normal balances (classes 2, 3, 4-debit, 5).
    • Passif (liabilities + equity): credit-normal balances (classes 1, 4-credit).
  4. Check it balances: total Actif must equal total Passif. If it doesn't, surface the gap rather than hiding it — it usually means unposted entries or a period filter mistake.

Do NOT

  • Do not derive assets/liabilities from invoice or bank-transaction lists directly; use the posted ledger / account_balances.
  • Do not assume account-class conventions without reading the chart of accounts.

If the ledger is empty

Say the books aren't posted yet. A bank accounts + account_balances snapshot can give a cash position (not a balance sheet) as a clearly-labelled fallback.

Present it

Two columns — Actif and Passif — grouped by class with subtotals, the as-of date, the currency, and an explicit "Actif = Passif ✓/✗" balance check.
