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.

Security

Grade A, and why

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 10d 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.

Closing Checklist

Purpose

Build and maintain a structured transaction closing checklist that captures every condition precedent, closing deliverable, and pre-closing covenant drawn from the transaction agreement. The skill can initialize a checklist from the agreement, fold in items surfaced by diligence, update item status, and produce a blocking and critical-path summary. It produces draft legal work product for attorney review — not legal advice and not a closing certification.

Use When

  • A deal team needs to initialize a closing checklist from a purchase agreement, merger agreement, or financing document.
  • Diligence findings have surfaced pre-closing action items — consents, regulatory filings, board or shareholder approvals, releases, or escrow mechanics — that must be tracked to closing.
  • The team needs to update the status of existing checklist items and surface what remains open.
  • A deal is approaching signing or closing and the team wants a consolidated view of open conditions and deliverables for attorney review.
  • The user asks for a "closing checklist," "conditions checklist," "pre-closing action list," or equivalent.

Required Inputs

  • The transaction agreement (purchase agreement, merger agreement, financing document, or equivalent) — required to initialize the checklist or verify item sourcing. Do not reconstruct or paraphrase conditions from memory or a description alone.
  • Deal context — deal name, transaction structure (e.g., stock purchase, asset purchase, merger, or financing [CONFIRM: structure]), and parties. If any of these are missing, ask for them before proceeding.
  • Operating mode — one of: initialize (build from the agreement), add (fold in diligence items), update (revise item status), or status report (surface blocking items and critical path).
  • Diligence findings — required only for add mode; a list or memo of findings that carry pre-closing action items.
  • Existing checklist — required for update and status report modes; provide the current checklist to be updated.
  • Optional: the practice group's practice-profiles/corporate.md if it has been populated and is loaded alongside this skill. If present, the skill uses its Standard Positions and Escalation Thresholds tables to benchmark the output and to gate escalation. If absent, the skill proceeds without practice-profile benchmarking and asks the user to supply standing positions inline if needed.

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.
