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 | $0.00060 | $0.02998 |
| Opus 5 | $0.00030 | $0.01499 |
| Sonnet 5 | $0.00012 | $0.00600 |
| Haiku 4.5 | $0.00006 | $0.00300 |
Grade A, and why
Capital Markets Closing Checklist 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.

Capital Markets Closing Checklist
Purpose
Organize the closing-workstream universe for a capital-markets transaction, from signing through closing, settlement, and any over-allotment closing — covering approvals, agreements, opinions, certificates, comfort, lock-ups, transfer-agent/DTC mechanics, listing and FINRA, blue-sky/Form D, funds flow, and post-closing filings. The skill builds the tracker; the attorney closes each condition. This skill provides draft work product for attorney review only and is not legal advice.
Use When
- A capital-markets transaction is in execution and the deal team needs the closing workstream organized.
- An issuer is preparing for an IPO, follow-on, registered direct, ATM, block trade, debt issuance, or private placement and the closing-condition universe needs to be tracked.
- Outside counsel is taking over a closing in mid-flight and needs the existing closing record audited for completeness.
Required Inputs
- Jurisdiction and governing law, or
[verify jurisdiction]. - Transaction type (IPO / follow-on / secondary / shelf takedown / private placement / debt issuance / registered direct / ATM / block trade / convertible / PIPE / Rule 144A) supplied by counsel.
- Agreement type (firm-commitment underwriting / best-efforts placement / private-placement subscription / debt purchase / other).
- Parties (issuer, selling stockholders, underwriters or placement agents, indenture trustee where applicable).
- Signing, pricing, and closing dates
[deadline verification required]. - Offering size and structure.
- Document set: purchase / underwriting agreement (draft or executed), prospectus / offering memorandum, indenture (if debt), lock-up agreements, transfer-agent posture, listing-application posture.
- Concurrent regulatory items: FINRA review status (where applicable), exchange-listing status, blue-sky/Form D posture, foreign-regulatory posture.
If the transaction type, agreement type, or signing/closing-date inventory 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.
