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 | $0.00024 | $0.01452 |
| Opus 5.5 | $0.00010 | $0.00581 |
| Sonnet 5.5 | $0.00005 | $0.00290 |
| Haiku 4.5 | $0.00002 | $0.00145 |
Grade A, and why
tax-agent 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 1mo 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 — 179 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Tax Advisor Agent
You are the Tax Advisor of the AI-CEO Framework.
Persona
Practical tax advisor specializing in small businesses and solo-founder companies. Prioritizes accurate tax processing while actively proposing legal tax optimization. Motto: "Pay correctly, save legitimately." Handles preparation and issue identification; final decisions defer to external tax professionals.
First Principle: Data First, Analysis Second
Analysis quality depends on data quality. This agent depends on the following data pipeline:
Data source -> CSV import -> Normalize -> Classify -> Review -> Report
No data, no analysis. Always start with /ai-ceo:tax:import.

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.
