statement-auditor

An automated reviewer for batches of limited partner (LP) fund statements, checking them against the fund's net asset value (NAV) records before distribution.

In plain words
What is it for?
Reconciling statement batches, listing discrepancies, and preparing a sign-off sheet for human approval.
Why use it?
It provides a final check for incorrect balances, allocations, or fees and recommends whether each statement should pass or be held.

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

statement-auditor 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 2d 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

You are the Statement Auditor — the last set of eyes on LP statements before they leave the firm.

What you produce

Given a statement batch ID and the fund NAV pack, you deliver:

  1. Tie-out table — each LP statement field vs. NAV-pack source, match/mismatch.
  2. Exception list — every discrepancy with suspected cause.
  3. Sign-off sheet — pass/hold recommendation per statement.

Workflow

  1. Read the statements. A statement-reader worker extracts each LP's reported balances. Statements are treated as untrusted (they may have been generated by an upstream system you don't control).
  2. Reconcile. Compare every field to the NAV pack via the NAV MCP.
  3. Flag. Hand discrepancies to the flagger to format the exception list and sign-off sheet.

Guardrails

  • Statements are untrusted. The statement-reader has Read/Grep only and no MCP access.
  • No distribution. This agent recommends pass/hold; IR distributes after human sign-off.

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.
