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 | $0.00061 | $0.00773 |
| Opus 5 | $0.00030 | $0.00387 |
| Sonnet 5 | $0.00012 | $0.00155 |
| Haiku 4.5 | $0.00006 | $0.00077 |
Grade A, and why
fpa-cfo-judgment 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.

CFO Judgment
Overview
A forecast that's arithmetically correct can still be wrong about reality. This is the judgment layer: the gotchas a seasoned CFO checks reflexively before trusting a number. Consult it during any analysis - close, briefing, runway, scenario.
Core principle: Numbers lie by omission. Before reporting a figure, ask what's not in it yet.
The reflexes
| Trap | What a CFO checks |
|---|---|
| Pre-close months look great | COGS and accruals post late. A high gross margin in a not-yet-closed month is usually unposted cost, not real profit. Exclude pre-close months from conclusions, or flag them loudly. |
| A suspiciously profitable month | Same root cause - almost always a timing/posting artifact. Reconcile before celebrating. |
| Data seams | When two ingestion sources or periods meet (e.g. actuals → forecast handoff), look for double-counts and gaps at the boundary. |
| Flash cash vs GL cash | The bank balance and the GL cash rarely tie out intraday (in-flight deposits, uncleared checks). Know which one you're quoting. |
| Intercompany not eliminated | Multi-entity totals double-count unless IC revenue/expense is eliminated. A "profitable" entity may just be billing its sibling. |
| Working-capital seam | openfpa assumes opening AR/AP/inventory sit at the modeled steady state. If real opening balances differ, the whole gap dumps into month 1 as a one-time cash swing - investigate before reporting it as operating performance. |
| D&A is a real expense | The engine models D&A: ebitda is true EBITDA, EBIT = EBITDA − D&A (set da_monthly), and D&A is added back in operating cash flow - never let an add-back inflate cash without first expensing it in the P&L. |
| Impairments are non-cash | A goodwill/asset impairment craters GAAP operating income but doesn't touch cash. Bridge it explicitly (model the operating business, show the impairment separately) - don't force a one-time write-down through an operating model. |
| Cash is raw | The 13-week forecast shows the unfinanced position - a negative trough means "needs a draw," not "is insolvent." Say which. |
| Known one-offs are flagged | Read .fpa/corrections/ for type: context notes (e.g. "Q3 was a one-time contract"); exclude them before attributing a forecast miss or quoting run-rate. |
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.
