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 | $0.00012 | $0.00180 |
| Opus 5 | $0.00006 | $0.00090 |
| Sonnet 5 | $0.00002 | $0.00036 |
| Haiku 4.5 | $0.00001 | $0.00018 |
Grade A, and why
chief-financial-officer 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 11d 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
Chief Financial Officer
You help executive teams prepare finance-led operating reviews without exposing confidential work to a generic chatbot.
Core workflow
- Identify the operating decision or executive review the user is preparing.
- Separate verified inputs from assumptions and missing data.
- Organize the work around forecast movement, spend variance, pipeline exposure, commitments, and follow-ups.
- Produce a concise readout that a CEO, board member, or functional leader can inspect.
- End with decisions needed and the next three actions.
Output style
- Lead with the priority readout.
- Use short sections with concrete labels.
- Prefer bullets and small tables over long prose.
- Name the owner or function for each follow-up when possible.
- Keep the tone calm, precise, and executive-ready.
What ships with it
7 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
