Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00002 | $0.01336 |
| Opus 5 | $0.00001 | $0.00668 |
| Sonnet 5 | $0.00000 | $0.00267 |
| Haiku 4.5 | $0.00000 | $0.00134 |
Grade A, and why
check-model 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 9d 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.
This is a copy
88% identical to check-model — 9 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.
How it starts
The opening of the file, as written. The whole thing — 139 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Model Checker
description: Debug and audit financial models for errors — circular references, broken formulas, hardcoded overrides, balance sheet imbalances, cash flow mismatches, and logic gaps. Use when a model isn't tying, producing unexpected results, or before sending to a client or IC. Triggers on "debug model", "model check", "audit model", "model won't balance", "something's off in my model", "check my model", "QA model", or "model review".
Workflow
Step 1: Ingest the Model
- Accept the user's Excel model (.xlsx or .xlsm)
- Identify model type: DCF, LBO, merger, 3-statement, comps, returns, or custom
- Map the structure: which tabs exist, how they're linked, where inputs vs. outputs live
Step 2: Structural Checks
Tab & Layout Review:
- Are inputs clearly separated from calculations?
- Is there a consistent color-coding convention? (blue = input, black = formula, green = link)
- Are there hidden tabs or rows that could contain overrides?
- Is the model flow logical? (assumptions → IS → BS → CF → valuation)
Formula Consistency:
- Check for hardcoded numbers inside formulas (partial hardcodes)
- Check for inconsistent formulas across row/column ranges (should be the same formula dragged across)
- Identify any #REF!, #VALUE!, #N/A, #DIV/0! errors
- Flag cells that are formatted as formulas but contain hardcoded values
Step 3: Integrity Checks
Balance Sheet:
- Total Assets = Total Liabilities + Equity (every period)
- If imbalanced, quantify the gap and trace where it breaks
- Check that retained earnings rolls forward correctly: Prior RE + Net Income - Dividends = Current RE
- Verify goodwill and intangibles flow from acquisition assumptions (if M&A model)
Cash Flow Statement:
- Ending cash from CF = Cash on BS (every period)
- Operating CF + Investing CF + Financing CF = Change in Cash
- D&A on CF matches D&A on IS
- Capex on CF matches PP&E rollforward on BS
- Working capital changes on CF match BS movements (AR, AP, inventory)
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.

check-model is a skill published in the GitHub repository yuping322/financial-services-plugins-new (17 stars, last pushed 6mo ago), licensed Apache-2.0. It adds 2 tokens to every session and 1,336 once invoked, about $0.0000 per session on Opus 5. A static security scan graded it A with 0 findings. It is 88% identical to check-model, differing in 9 lines, and is treated as a copy.
