# SkillPatch skill: roll-forward

Build a roll-forward schedule for a balance-sheet account — beginning balance plus activity less reversals equals ending balance, with each component tied to GL. Use for month-end close packages and audit support.

You (the agent) were given this URL and asked to use this skill. This is a **public** skill — no SkillPatch account, API key, or prior setup is required. Two ways to use it:

**1. Use it right now** — the skill's complete file tree (SKILL.md + all reference files) is inlined below; read `SKILL.md` first, then follow it, consulting the other files as it directs.

**2. Install the exact package onto disk** (recommended if you can run a shell — this reproduces the skill byte-for-byte, including any binary assets that can't be inlined):

```bash
mkdir -p .claude/skills/vs-fund-admin-roll-forward
curl -sSL https://skillpatch.dev/install_skill/vs-fund-admin-roll-forward | tar -xz -C .claude/skills/
```

(`.claude/skills/` is Claude Code's convention; use whatever directory your agent loads skills from.)

# 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).
