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 | $0.00050 | $0.03491 |
| Opus 5 | $0.00025 | $0.01746 |
| Sonnet 5 | $0.00010 | $0.00698 |
| Haiku 4.5 | $0.00005 | $0.00349 |
Grade A, and why
Cease and Desist Response 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 — 162 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Cease and Desist Response
Purpose
Produce a structured triage memo for a client who has received a cease-and-desist letter or similar intellectual property demand. The memo summarizes the assertion, assesses the sender's claimed rights and the client's exposure, presents response options with tradeoffs, triages any stated deadline, identifies immediate actions, and offers a draft recommendation — all for attorney review before the client responds, declines to act, or makes any commitment.
This is draft legal work product for attorney review. It is NOT a legal opinion on the merits, NOT advice about whether the client infringes, and does NOT determine the validity of any asserted right.
Use When
- A client has received a cease-and-desist letter, demand letter, or similar written IP demand asserting trademark, copyright, patent, trade secret, or related rights.
- A user asks to "review this C&D," "what does this letter mean," or "what should we do about this demand."
- A client wants a structured briefing document to share with outside IP counsel.
- A client needs to understand the range of response options and their tradeoffs before consulting an attorney.
Required Inputs
- The inbound letter: the full text, or a detailed description including: the sender's identity; the right(s) asserted (trademark, copyright, patent, trade secret, or other); the alleged infringing conduct; the specific demand (cease use, remove content, pay damages, execute a license, etc.); any stated deadline; and the overall tone.
- The client's factual self-assessment: the client's honest account of whether it is actually doing what the letter alleges, and any relevant context (when the conduct began, whether it was aware of the asserted right, any prior dealings with the sender).
If the letter text or description is not provided, stop and request it before proceeding. If the client's factual self-assessment is not provided, flag it as missing and note that the exposure assessment will be incomplete without it. Never fabricate any element of either input.
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.

Cease and Desist Response is a skill published in the GitHub repository zgbrenner/agentcounsel (19 stars, last pushed 1mo ago), licensed MIT. It adds 50 tokens to every session and 3,491 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
