roll-forward

roll-forward is a skill for Claude Code from anthropics/financial-services. It costs 42 tokens per session (315 once invoked), scanned A, original, Apache-2.0.

A balance-sheet roll-forward schedule that starts with an account’s opening balance, adds activity, subtracts reversals and payments, and checks the result against the ending general-ledger balance.

In plain words
What is it for?
Use it for month-end close and audit support on accounts such as accruals, with each movement tied to a ledger query or supporting document.
Why use it?
It shows how an account changed during the period and highlights any unexplained difference instead of hiding it with a plug.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

roll-forward scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

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).

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
