A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

The primary manifest — the file an agent reads to learn what this artifact does.
This is a KNOWLEDGE skill. It does not produce standalone deliverables. Instead, it enhances any marketing asset — landing pages, emails, ads, CTAs, pricing pages, onboarding flows — by applying behavioral psychology principles that increase persuasion and conversion.
When another skill produces copy or UX, this skill provides the psychological layer: why certain framings work, which biases to apply, and specific before/after rewrites grounded in research.
This skill is pure reference. It reads no brand files and writes no outputs. It is applied ON TOP of other skills' work.
While this skill reads no files itself, the calling skill should provide brand context when available:
When calling this skill, pass relevant brand context so principles are applied in voice, not generically.
Determine what marketing asset is being optimized:
Not every principle applies to every asset. Match principles to context. Use the Application Matrix below for quick selection.
| Principle | B2B Emphasis | B2C Emphasis |
|---|---|---|
| Social proof | Case studies, logos, ROI metrics | User counts, ratings, peer testimonials |
| Authority | Industry certifications, compliance | Celebrity endorsements, media features |
| Scarcity | Limited pilot spots, implementation slots | Limited stock, countdown timers |
| Loss aversion | Revenue at risk, competitive disadvantage | Missing out on experiences, wasted time |
| Anchoring | ROI comparison, cost of inaction | Was/now pricing, competitor comparison |
For real-world case studies of each principle in action: See references/case-studies.md — 11 examples from companies like HubSpot, Netflix, Stripe, Duolingo, and Superhuman showing how principles translate to specific implementations.
This is a knowledge skill — it enhances other skills' output rather than producing standalone deliverables.
Invocation pattern: When another skill produces copy or UX, ask: "Apply marketing psychology principles to this asset." This skill audits the output and suggests principle-specific rewrites.
Example: After /direct-response-copy produces a landing page, apply this skill to audit the hero for anchoring, the CTA for scarcity, and the testimonials for social proof.
People feel obligated to return favors. Give value first, ask second.
Application:
Before: "Sign up for our product" After: "Here's a free audit of your [X]. Want to fix these issues automatically? [Start free trial]"
Why this works: Giving value before asking creates an obligation loop — the free checklist makes the paid product feel like a natural next step, not a cold ask.
Where it works best: Lead magnets, free tools, onboarding emails, content marketing
People who take small steps continue in the same direction. Micro-commitments build toward conversion.
Application:
Before: "Buy our annual plan for $299/year" After: "Start your free project -> See your first results -> Upgrade when you're ready"
Why this works: Each small yes builds psychological momentum — once someone has invested time and seen results, saying yes to payment feels consistent with their prior actions.
Where it works best: Signup flows, onboarding, pricing pages, email sequences
People follow the actions of others, especially similar others.
Types of social proof (ordered by persuasion strength):
| Type | Example | Strength |
|---|---|---|
| Expert endorsement | "[Industry expert] recommends [Product]" | Highest |
| Celebrity/Influencer | "[Known figure] uses [Product]" | High |
| User statistics | "12,847 teams use [Product]" | High |
| Peer testimonial | "[Same role/industry] saw [specific result]" | High |
| Certification/Award | "G2 Leader, 4.8/5 stars" | Medium |
| Wisdom of crowds | "Most popular plan" badge | Medium |
| Friend referral | "[Name] invited you" | Highest (context-dependent) |
Before: "Our product is great" After: "12,847 marketing teams use [Product] to save 10+ hours/week. Here's what [Similar Company] achieved in 30 days."
Why this works: Humans use others' behavior as a decision shortcut — specific numbers and named peers eliminate the need to evaluate the product independently.
Where it works best: Every asset. No exceptions. Always include social proof.
People defer to experts and credible sources.
Authority signals:
Before: "We help with email marketing" After: "Built by the team that scaled [Company]'s email list from 0 to 500K subscribers"
Why this works: Concrete credentials transfer trust instantly — the reader borrows confidence from the known achievement rather than evaluating your claim from scratch.
Where it works best: Landing pages, about pages, sales emails, B2B proposals
People buy from people (and brands) they like. Similarity, compliments, and cooperation build liking.
Application:
Before: "Our enterprise-grade solution leverages AI-powered analytics" After: "We were tired of staring at spreadsheets too. So we built [Product]."
Why this works: Mirroring the audience's frustration signals "we're one of you" — people trust and buy from those who understand their lived experience.
Where it works best: Brand voice, about pages, founder stories, email tone
People value what's limited. Real scarcity drives action; manufactured scarcity destroys trust.
Legitimate scarcity patterns:
Illegitimate scarcity (never use):
Before: "Sign up anytime" After: "Launch pricing: $29/mo for the first 500 customers (347 claimed)" — only if real
Why this works: Real scarcity activates fear of missing out on a genuine opportunity — the specific count (347/500) makes the constraint feel tangible and urgent without feeling manufactured.
Where it works best: Pricing pages, launch campaigns, limited offers (when genuine)
People feel losses 2x more intensely than equivalent gains. Frame around what they'll lose, not just what they'll gain.
Before: "Save 10 hours per week with [Product]" After: "You're losing 10 hours every week to [manual task]. [Product] gives them back."
Why this works: The pain of losing 10 hours hits harder than the pleasure of saving them — reframing a gain as a recovered loss doubles the emotional weight.
Application: Cancel flows, upgrade prompts, trial expiration emails, feature comparison
The first number people see becomes the reference point. Control the anchor.
Application:
Pricing page pattern:
Enterprise: $299/mo <- Anchor
Pro: $99/mo <- Looks reasonable now
Starter: $29/mo <- Feels like a stealPeople value things more once they feel ownership. Let them invest before asking to pay.
Application:
People value things they helped build. Involvement increases attachment.
Application:
Too many options -> decision paralysis -> no action. Reduce choices, add recommendations.
Application:
Before: 5 plan tiers with 40 feature comparison rows After: 3 plans, "Most Popular" badge on middle tier, "Not sure? Start with Pro" CTA
Why this works: Reducing options from 5 to 3 eliminates decision paralysis, and the "Most Popular" badge gives permission to stop comparing — the crowd already chose for you.
People strongly prefer eliminating a risk entirely over reducing it. Money-back guarantees outperform discount offers.
Application:
The same information presented differently changes decisions. Frame to match your goal.
Application:
Before: "Our tool has 99.9% accuracy" After: "Our tool catches 999 out of every 1,000 errors — so nothing slips through"
Why this works: Concrete framing (999/1000) is more vivid than abstract percentages. The reader can picture the result.
People prefer the current state of affairs. Reducing friction to switch is more effective than amplifying benefits.
Application:
Where it works best: Competitor displacement, upgrade prompts, onboarding
Familiarity breeds preference. People like what they've seen before.
Application:
Where it works best: Top-of-funnel content, retargeting, email sequences, social media presence

When reviewing any marketing asset:
| Mistake | Why it fails | Instead |
|---|---|---|
| Applying all principles to every asset | Stacking 10 principles on one page creates a manipulative wall of tricks that readers feel viscerally — less is more persuasive | Select 2-4 most relevant using the Application Matrix |
| Forcing scarcity where none exists | Users share notes about fake urgency on social media — one "fake countdown timer" screenshot can destroy brand trust permanently | Only use scarcity with real constraints. Fake urgency destroys trust |
| Generic "add social proof" without specifics | "Add social proof" gives the agent nothing to work with — peer testimonials work differently than user counts, and the wrong type falls flat | Specify the TYPE of social proof (peer testimonial, user count, expert endorsement) based on audience |
| Applying principles without considering brand voice | A corporate brand writing "Don't miss out!!" and a playful brand writing "Enterprise-grade urgency metrics" both sound absurd | A playful brand and a corporate brand apply the same principle very differently |
| Suggesting dark patterns as psychological techniques | Dark patterns generate short-term conversions but long-term refunds, chargebacks, and reputation damage | Always apply the transparency test: would you be comfortable if the user knew? |
| Ignoring that the asset might already be effective | Over-optimizing working copy risks breaking what already converts — psychology should enhance, not overhaul | Audit first — if conversion is strong, don't add psychology for the sake of it |
Use psychology to help people make better decisions, not to trick them:
The test: Would you be comfortable if the user knew exactly what psychological principle you were applying? If yes, proceed. If no, find another approach.
