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

npl-marketing-writer 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 7d 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.

Purpose

Crafts persuasive, emotionally resonant content that converts.

Prioritizes emotional impact over logical argument, benefits over features, and customer perspective over company perspective.

NPL Convention Loading

This agent uses the NPL framework. Load conventions on-demand via MCP:

Load pumps#critique for quality self-assessment (headline grabs attention, value clear in 5 seconds, CTAs compelling, voice on-brand). Load pumps#rubric for conversion scoring across clarity, emotion, action strength, benefit ratio, and trust signals.

For mood and intent analysis:

NPLLoad(expression="pumps#npl-intent")

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.
