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 | $0.00073 | $0.01036 |
| Opus 5 | $0.00036 | $0.00518 |
| Sonnet 5 | $0.00015 | $0.00207 |
| Haiku 4.5 | $0.00007 | $0.00104 |
Grade A, and why
pn-financial-model-audit 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 7d 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.
How it starts
The opening of the file, as written. The whole thing — 106 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Financial model audit
When to use
- After
pn-dcf-model,pn-comps-analysis, or any LBO / 3-statement build, before the model feeds a deliverable. - When a user supplies a spreadsheet or table for review.
- As a quality gate in a modeling workflow step before proceeding to memo or presentation.
Pre-requisites
Load get_skill("pn-fsi-analyst-discipline"). Identify what was supplied: agent-produced structured output, user-uploaded file, or inline table.
Audit checklist
1. Hardcode detection
- Scan each row and formula for values that should be calculated but are typed as constants.
- Common offenders: tax rate typed as a number instead of referencing an assumption cell; D&A that does not roll from a schedule; NWC changes that are zero rather than formula-driven.
- Flag each hardcode: location (row / column / step), expected behavior, suggested fix.
2. Formula integrity
- Verify that each calculated line follows from the stated formula (e.g.
UFCF = NOPAT + D&A – Capex – ΔNWC). - Check for sign errors: cash outflows (capex, NWC increase) must be subtracted; inflows (D&A add-back) added.
- Check that growth rates are applied to the correct base (prior-year, not base-year, for compound growth).
- Check that discount factors use consistent periodicity (annual vs. mid-year convention; state which and apply uniformly).
3. Balance checks
For 3-statement models:
- Assets = Liabilities + Equity (balance sheet check; flag any period that does not balance).
- Cash flow statement: net change in cash reconciles to balance sheet cash movement.
- Retained earnings roll: opening RE + Net income – Dividends = Closing RE.
For DCF / LBO:
- PV of UFCF + PV of TV = EV (verify discounting arithmetic).
- Equity bridge: EV – Net debt – Minority – Preferred = Equity value.
- Returns check (LBO): sponsor equity = purchase equity – fees; exit equity = exit EV – exit debt; MOIC = exit equity / sponsor equity.
4. Circular references
- Flag any circular dependency (e.g. interest expense referencing ending debt, which depends on interest). Note whether it is intentional (iterative solve) and whether iteration is enabled.
- If not intentional, suggest the decoupling fix.
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.

pn-financial-model-audit is a skill published in the GitHub repository perniemann/pnCore (0 stars, last pushed 4d ago), licensed MIT. It adds 73 tokens to every session and 1,036 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
