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 | $0.00076 | $0.02895 |
| Opus 5 | $0.00038 | $0.01448 |
| Sonnet 5 | $0.00015 | $0.00579 |
| Haiku 4.5 | $0.00008 | $0.00290 |
Grade A, and why
Section 16 and Beneficial Ownership Triage 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.
How it starts
The opening of the file, as written. The whole thing — 131 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Section 16 and Beneficial Ownership Triage
Purpose
Triage the facts that drive Section 16 (Forms 3/4/5) reporting and Schedule 13D / 13G beneficial-ownership reporting. The skill builds the reporting-person fact map and the threshold-trigger flag list; the attorney concludes insider status, beneficial ownership, group formation, and any reporting obligation or deadline. This skill provides draft work product for attorney review only and is not legal advice.
Section 16, §13(d)/(g), and the underlying SEC rules have been amended substantively. This skill does not assert which rule version is current; every rule-tied element carries [verify current SEC rule version at time of review].
Use When
- A potential reporting person (insider candidate, 5%+ beneficial owner, group candidate) needs the underlying facts organized for attorney analysis.
- A transaction triggers a question about new Section 16 designation, a new 13D/13G filing, or a group-formation analysis.
- An issuer needs the Section 16 universe at the company level mapped (directors, officers, 10%+ owners).
Required Inputs
- Jurisdiction and governing law, or
[verify jurisdiction]. Federal U.S. by default; foreign-private-issuer considerations where applicable. - Issuer profile (reporting status, Exchange Act §12 registration of the class).
- Reporting-person profile: individual / entity / fund / fund family.
- The reporting person's direct and indirect holdings, including options, warrants, convertibles, derivatives.
- Voting and investment power facts: agreements, proxies, arrangements that allocate power.
- Group-candidate facts: each other person whose conduct or agreements might form a group with the reporting person.
- Transaction history: date and category of each transaction within the period the user is examining.
- The class of equity securities at issue and its outstanding share count.
If the issuer's §12 registration status, the reporting-person holdings, or the class outstanding-share count is missing, stop substantive analysis and return an intake gap list.
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.
