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 | $0.00073 | $0.01643 |
| Opus 5 | $0.00036 | $0.00822 |
| Sonnet 5 | $0.00015 | $0.00329 |
| Haiku 4.5 | $0.00007 | $0.00164 |
Grade A, and why
demand-letter 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 5d 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.
/demand-letter — Demand Letter & Client Correspondence Drafter
⚠️ AI-ASSISTED DRAFT — ATTORNEY REVIEW REQUIRED Drafted from the case facts and template you provided. Does not verify accuracy, completeness, or legal sufficiency, and does not set a demand amount or assess liability. You are the author of record — review, revise, and send it yourself.
This skill drafts one of two things from an attached case folder:
- A first-pass demand letter — populates your firm's demand-letter template with the case facts you've provided.
- A plain-English client status-update email — summarizes where the matter stands, in language a client (not a lawyer) can follow.
This skill drafts from what you provide. It never invents facts, and it never sets a dollar figure, apportions liability, or reaches a legal conclusion — that is your call to make, not the draft's. If the case facts or template are too sparse to draft accurately, it asks before proceeding.
Invocation
/demand-letter
/demand-letter demand letter
/demand-letter status update
Workflow
Step 1 — Collect inputs
Case facts — read from the attached workspace folder if one is attached: intake notes, correspondence, medical/treatment summaries, incident reports, whatever the attorney has provided. If no folder is attached, ask the attorney to attach one or paste the relevant facts directly into the conversation.
Output type — if not specified in the invocation, ask:
"Are we drafting a demand letter or a client status-update email?"
If drafting a demand letter, also look for the firm's own demand-letter template in the attached folder (structure, letterhead conventions, standard sections/phrasing). If none is found, ask:
"I don't see a demand-letter template in the attached folder. Do you have one you'd like me to follow, or should I ask you for the recipient and structure details directly?" Do not silently fall back to a generic demand-letter structure. Only offer a generic structure if the attorney explicitly asks for one — and label it clearly as generic, not firm-standard.
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.

demand-letter is a skill published in the GitHub repository protomated/protomated-plugins-official (2 stars, last pushed 2d ago), licensed Apache-2.0. It adds 73 tokens to every session and 1,643 once invoked, about $0.0004 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 2026-08-31.
