roll-forward

roll-forward is a skill for Claude Code, Codex from leecyno1/boutique-skills. It costs 42 tokens per session (315 once invoked), scanned A, a copy of roll-forward, MIT.

A tool for building a balance-sheet account schedule that starts with an opening balance, adds and subtracts activity, and reaches the closing balance in the general ledger.

In plain words
What is it for?
Use it for month-end close work and audit support, with each component linked back to accounting records.
Why use it?
It shows how an account changed during the period and exposes any unexplained difference instead of hiding it in an adjustment.

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 2mo 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.

Origin

This is a copy

100% identical to roll-forward — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

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.
