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

Tender Letter Review 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.

Tender Letter Review

Purpose

Review a tender letter, notice of claim, additional insured tender, or contractual indemnity tender into a completeness checklist, a missing-documents list, risk flags, and proposed revisions for attorney review. This skill organizes what the tender contains and identifies gaps; it reaches no conclusion that the tender is timely, valid, or sufficient.

Use When

  • A tender letter, claim notice, additional insured tender, or contractual indemnity tender must be reviewed before it is sent or after it is received.
  • The user needs the tender checked for completeness, supporting documents, and risk flags.
  • A draft tender needs attorney-review revisions before finalizing.

Required Inputs

  • The tender or notice letter, with source references — or, if drafting-stage, the draft.
  • The asserted basis for the tender — the policy (with its additional insured provisions) and/or the contract (with its insurance and indemnity clauses), with source references.
  • The user's role (tendering party, party receiving the tender, insured, additional insured, insurer, broker, or other) — or not provided.
  • The claim or matter being tendered — or not provided.
  • The duties tendered — defense, indemnity, or both — or not provided.
  • Any timing facts the user supplies (date of loss, date of suit, date of tender), echoed and marked [deadline verification required].
  • Jurisdiction and governing law, or [verify jurisdiction].

If the letter, the asserted basis, or the user's role is missing, record it as not provided and return the missing-information list first.

Do Not Use When

  • The request is to conclude whether the tender is timely, valid, sufficient, or properly made.
  • The request is to determine additional insured status, a duty to defend or indemnify, or a contractual indemnity obligation.
  • The request is to conclude on the consequences of notice timing, or for legal advice.
  • The request is to approve sending the tender as final (the attorney does that).
