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 | $0.00222 | $0.13619 |
| Opus 5 | $0.00111 | $0.06809 |
| Sonnet 5 | $0.00044 | $0.02724 |
| Haiku 4.5 | $0.00022 | $0.01362 |
Grade C, and why
officecli-financial-model scanned grade C with 2 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 3d 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.

OfficeCLI Financial-Model Skill
This skill is a scene layer on top of officecli-xlsx. Every xlsx hard rule — shell quoting, incremental execution, Help-First Rule, visual delivery floor, CFO 4-color code (blue input / black formula / green cross-sheet / yellow-fill assumption), number-format standards (years as text, zero as -, % one decimal, negatives in parens), assumption-cell discipline, CSV batch import, chart data-feed forms (a/b/c), the 5-gate Delivery cycle, cache-drift guidance, Known Issues (the cross-sheet ! trap, batch + resident for formulas, renderer caveats) — is inherited, not re-taught. This file adds only what a financial model requires on top: three-zone architecture, 3 model-type recipes (3-statement / DCF / LBO), sensitivity + scenario protocols, financial-function patterns, circular-reference discipline, and model-specific Delivery Gates 4–6.
When the xlsx base rules cover it, the text here says → see xlsx v2 §X. Read skills/officecli-xlsx/SKILL.md first if you have not.
Setup
If officecli is missing:
- macOS / Linux:
curl -fsSL https://raw.githubusercontent.com/iOfficeAI/OfficeCLI/main/install.sh | bash - Windows (PowerShell):
irm https://raw.githubusercontent.com/iOfficeAI/OfficeCLI/main/install.ps1 | iex
Verify with officecli --version (open a new terminal if PATH hasn't picked up). If install fails, download a binary from https://github.com/iOfficeAI/OfficeCLI/releases.
Help-First Rule
This skill teaches what a financial model requires, not every CLI flag. When a prop name / alias / enum is uncertain, consult help BEFORE guessing: officecli help xlsx [element] [--json]. Help is pinned to installed version — when this skill and help disagree, help wins. Every --prop X= below was verified against officecli help xlsx <element> on v1.0.63.
Mental Model & Inheritance
Inherits xlsx v2. Read skills/officecli-xlsx/SKILL.md first. This skill assumes you know create / open / close, set values/formulas, batch heredocs for cross-sheet formulas, /SheetName/A1 paths, named ranges, the 5-gate Delivery cycle, the cross-sheet ! trap, and that cross-sheet formulas go non-resident (single batch OR individual set), never batch-while-resident.
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.
