What roll-forward does

The skill produces a roll-forward table for an account or account group, entity, and period. It walks from prior-period closing balance to the ending balance across additions, accruals, reversals, settlements, reclassifications, and foreign exchange translation.

Every activity entry references a specific general ledger query with date ranges and journal source filters through the internal-gl MCP tool. The schedule must foot mathematically. If components do not sum to the ending balance, the tool surfaces the unexplained variance rather than plugging the difference.

Running this requires the internal-gl MCP connection in your agent environment, because the skill needs it to run queries and cite sources for every line item.

What it helps with

  • build a balance sheet roll-forward schedule
  • tie activity lines directly to general ledger queries
  • surface unexplained gaps between beginning and ending balances
  • assemble supporting documentation for period-end close and audits

Example prompts for the agent

  • Build a roll-forward schedule for accrued expenses for entity Acme over the prior period
  • Tie beginning and ending balances for accounts payable with general ledger query citations
  • Generate a roll-forward table for prepaid assets and flag any foot check failure

# Roll-forward

Given an account (or account group), entity, and period, produce a roll-forward that ties beginning to ending.

## Structure

```
Beginning balance (per prior-period close)      X
  + Additions / new activity                    A
  + Accruals booked this period                 B
  − Reversals of prior accruals                (C)
  − Payments / settlements                     (D)
  ± Reclasses / adjustments                     E
  ± FX translation                              F
Ending balance (per GL at period end)           Y
```

## Tie each line

- **Beginning** — prior-period close package, or GL balance at prior-period end date.
- **Each activity line** — a GL query (account + date range + journal-source filter) via the internal-gl MCP. Cite the query.
- **Ending** — GL balance at period-end date.

The schedule **must foot**: `X + A + B − C − D + E + F = Y`. If it doesn't, the gap is an unexplained item — surface it, don't plug it.

## Output

The roll-forward table with a "ties to" column citing the GL query or document for every line, plus a foot check (pass/fail and the unexplained delta if any).
