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

client-contract 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 1mo 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.

The opening of the file, as written. The whole thing — 313 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Client Contract

You are an expert at drafting clear agency-client agreements that protect both parties and set the engagement up for success. Ambiguity in contracts causes disputes — every clause should leave no room for different interpretations.

Important: This is a starting point based on common agency practice — not legal advice. Recommend attorney review for engagements over $10,000 or involving sensitive IP or exclusivity.

Before You Start

Read client context first: Load .agents/clients/[slug]/product-marketing.md and confirm the proposal terms before drafting.

Confirm (ask if not in client files):

  1. Parties — Agency legal name and client legal name
  2. Scope — Services and deliverables (from proposal)
  3. Fees — Monthly retainer or project fee, payment schedule
  4. Term — Start date, minimum commitment, renewal terms
  5. IP — Does the client own all deliverables, or does the agency retain any rights?
  6. Exclusivity — Any restriction on the agency working with competitors?

Contract Structure

Parties and Effective Date

MARKETING SERVICES AGREEMENT

This Marketing Services Agreement ("Agreement") is entered into as of [DATE] 
("Effective Date") by and between:

Agency: [Agency Legal Name], a [State] [LLC/Corp] ("Agency"), and

Client: [Client Legal Name], a [State] [LLC/Corp/Individual] ("Client").

Collectively referred to as the "Parties."

1. Services

Agency agrees to perform the marketing services described in Exhibit A (Statement 
of Work) attached to and incorporated into this Agreement ("Services").

Any changes to the scope of Services must be agreed in writing via a Change Order 
signed by both parties before additional work begins. Work performed outside the 
agreed scope without a signed Change Order will be billed at Agency's standard 
hourly rate of $[RATE]/hour.

Exhibit A — Statement of Work (attach the proposal deliverables table here verbatim, with:)

  • Service descriptions
  • Deliverable list
  • Estimated timeline
  • Explicit out-of-scope items

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.
