What it does

Behavioral Marketing is an agent skill from cbrock84/headcount. Applies decision science and cognitive bias research to marketing and product decisions — how people actually choose under uncertainty, and how framing, defaults, sequencing, and social context change behavior. Use this to diagnose why a well-argued offer is not converting, to structure choices and pricing presentation, to design an experience around how attention and memory work, or to pressure-test whether a persuasion tactic is legitimate or manipulative.

Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/sources.md`).

It sits in Marketing & SEO, covering Marketing psychology. The repository describes itself as: An agent organization structured as a company — 15+ departments, 125+ skills, each independently installable, citing the standards and regulators that settle the question. Runs… The licence is MIT.

When your agent uses it

  • Tasks that involve Marketing psychology

Example prompts

  • “Use the behavioral-marketing skill to apply decision science and cognitive bias research to marketing and product decisions — how people actually…”
  • “/behavioral-marketing”

What it can do on your machine

Read from SKILL.md and the folder at commit 98d1c17. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Behavioral Marketing loads about 1.3k tokens when it runs, and up to ~2.1k if it reads all its reference files. Until then it costs about 121 tokens; SKILL.md has 707 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~121
When it runs · the whole SKILL.md, loaded when a task matches
~1.3k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~2.1k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Applies decision science and cognitive bias research to marketing and product decisions — how people actually choose under uncertainty, and how framing, defaults, sequencing, and social context change behavior. Use this to diagnose why a well-argued offer is not converting, to structure choices and pricing presentation, to design an experience around how attention and memory work, or to pressure-test whether a persuasion tactic is legitimate or manipulative.

Behavioral marketing

People do not evaluate offers on merit and then act. They decide fast, under uncertainty, using whatever the context makes salient — and then explain the decision afterward. Marketing that assumes otherwise loses to marketing that does not.

The effects that most often explain a stuck conversion

Reference dependence. Nothing is judged absolutely. A price is high or low relative to whatever was shown first, so what you present first sets the frame for everything after it.

Loss aversion. Losing something registers considerably more than gaining the equivalent. This is why switching costs are underestimated by sellers and overestimated by buyers, and why "what you are currently losing" often outperforms "what you could gain."

Choice overload. More options reduce the likelihood of any choice being made. Beyond a small number, each additional option raises the cost of deciding faster than it raises the chance of a good match. If a pricing page has seven tiers, the problem is not the copy.

Status quo and default effects. Doing nothing is the most-chosen option in almost every context, and whatever is pre-selected is disproportionately taken. Whether a default exists is often a bigger lever than anything in the argument around it.

Social proof. Evidence of what similar others did carries more weight than claims about quality — and specificity matters. "Used by four hundred logistics teams" works where "trusted by thousands" does not, because the first is checkable and names a peer group.

Zero-price effect. Free is not a very low price; it is a different category that suspends cost-benefit reasoning. This makes free tiers powerful acquisition tools and dangerous pricing anchors.

Present bias. Immediate costs and benefits are weighted far above future ones. An annual plan competes against a monthly one on the immediacy of the charge, not on total value.

Goal-gradient and endowed progress. Effort increases as a visible goal approaches, and progress already granted counts. Progress indicators work; starting someone partway along works better.

Peak-end. An experience is remembered by its most intense moment and its ending, not its average. The last screen of onboarding and the cancellation flow carry disproportionate memory weight.

Using this without becoming manipulative

Every effect above can be used to help someone decide well or to extract a decision they would regret. The distinction is not subtle, and it is testable:

  • Would the customer be comfortable if you explained the technique to them? Anchoring against a real higher-value plan passes. A fake original price does not.
  • Does it help them decide, or prevent them deciding? Reducing choice overload helps. A countdown that resets on refresh does not.
  • Does it survive a satisfied customer? Tactics that work only until the person notices produce churn, chargebacks, and in several jurisdictions regulatory exposure — dark patterns around cancellation and consent are now specifically enforced.

Scarcity and urgency deserve particular caution: legitimate when real and stated precisely, corrosive when manufactured. A false constraint is the single fastest way to lose a customer who was going to buy anyway.

Reasoning about it

  • Look for the constraint, not the list. One thing usually blocks the decision. Applying six techniques to a page with an unclear value proposition addresses none of them.
  • Second-order effects. A tactic that raises conversion and raises refunds has not worked. Judge against downstream behavior, not the immediate step.
  • Effects are contextual and interact. Published effect sizes are directional, not predictions. Treat every application as a hypothesis to test rather than a known quantity — this is where behavioral marketing most often overreaches.

Sources

references/sources.md in this skill lists the outside authorities that settle the questions here — what each one is authoritative for, and what you may do with it. Check them before answering on anything they cover, and cite what you used. Most are free to read and not free to reproduce; the use note on each is binding.

Never

  • Deploy an effect without being able to name the mechanism. A tactic borrowed without its mechanism fails silently in a context that differs in ways nobody checked.
  • Manufacture scarcity, urgency, or social proof that is not true. It works once and costs the relationship permanently.
  • Treat a published effect size as a guaranteed lift. Those numbers come from populations and contexts that are not yours.
