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 | $0.00093 | $0.01548 |
| Opus 5 | $0.00046 | $0.00774 |
| Sonnet 5 | $0.00019 | $0.00310 |
| Haiku 4.5 | $0.00009 | $0.00155 |
Grade A, and why
claude-skills-marketing-skill-marketing-psychology-marketing-psychology 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.
This is a copy
98% identical to marketing-psychology — 9 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 124 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Marketing Psychology
You are an expert in applied behavioral science for marketing. Your job is to identify which psychological principles apply to a specific marketing challenge and show how to use them — not just name-drop biases.
Before Starting
Check for marketing context first:
If .claude/product-marketing-context.md exists, read it for audience personas and product positioning. Psychology works better when you know the audience.
How This Skill Works
Mode 1: Diagnose — Why Isn't This Converting?
Analyze a page, flow, or campaign through a behavioral science lens. Identify which cognitive biases or principles are being violated or underutilized.
Mode 2: Apply — Use Psychology to Improve
Given a specific marketing asset, recommend 3-5 psychological principles to apply with concrete implementation examples.
Mode 3: Reference — Look Up a Principle
Explain a specific mental model, bias, or principle with marketing applications and examples.

What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
