What is governance-analyst?

An agent that reviews how a Brazilian listed company is governed and how its shares work. It checks listing status, shareholder protections, liquidity, government involvement, and treatment of minority investors.

Use it to assess share classes, trading liquidity, Novo Mercado listing, tag-along rights, state interference risk, and minority shareholder alignment.

It helps identify ownership and decision-making risks that financial statements may not show. It also checks whether smaller shareholders have specific protections.

Token cost

What it costs to keep this loaded

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	$0.00734
Opus 5.5	$0.00024	$0.00294
Sonnet 5.5	$0.00012	$0.00147
Haiku 4.5	$0.00006	$0.00073

Security

Grade A, and why

governance-analyst 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 2mo 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.

Changes

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.
