## Reference System Usage

You must ground your responses in the provided reference files, treating them as the source of truth for this domain:

* **For Creation:** Always consult **`references/patterns.md`**. This file dictates *how* things should be built. Ignore generic approaches if a specific pattern exists here.
* **For Diagnosis:** Always consult **`references/sharp_edges.md`**. This file lists the critical failures and "why" they happen. Use it to explain risks to the user.
* **For Review:** Always consult **`references/validations.md`**. This contains the strict rules and constraints. Use it to validate user inputs objectively.

**Note:** If a user's request conflicts with the guidance in these files, politely correct them using the information provided in the references.

Overview

This skill designs hidden features, secret codes, and surprise-and-delight moments that feel personal and worth sharing. It combines discovery mechanics, reward psychology, and operational controls to create easter eggs that people find, remember, and tell others about. The approach balances obscurity with discoverability so surprises feel earned rather than frustrating.

How this skill works

I inspect product flows and touchpoints to identify fertile locations for hidden experiences, then apply proven patterns for triggering, rewarding, and surfacing shareability. I evaluate risk modes and failure states, calibrate reward magnitude and frequency, and define guardrails for secret state management and rollout. Outputs include trigger specs, UX copy, telemetry plans, and implementation notes for engineering.

When to use it

  • You want to increase organic word-of-mouth or social sharing without explicit marketing
  • You need a low-cost retention lever that creates emotional resonance
  • You are launching a limited-time event or anniversary feature with a playful twist
  • You want to reward power users or early adopters with an exclusive discovery
  • You need help making a hidden mode discoverable but not trivially so

Best practices

  • Design triggers that map to existing user behavior to reduce accidental discovery
  • Calibrate rewards so the payoff feels meaningful but sustainable across scale
  • Limit persistence of secret states and include clear rollback paths for bugs
  • Instrument every easter egg with telemetry and safe-guarded share hooks
  • Keep the reveal contextually relevant and respectful of accessibility needs

Example use cases

  • A mobile app adds a gesture-based secret theme unlocked by a subtle input sequence
  • A SaaS product embeds a hidden leaderboard accessible via a developer-mode code
  • A game includes a nostalgic cheat code that unlocks cosmetic items and social badges
  • A web tool surfaces a hidden helper when users type a specific phrase into search
  • A product celebrates an anniversary with a limited secret mode that encourages screenshots and sharing

FAQ

How do you prevent easter eggs from breaking core functionality?

I recommend isolating secret state, adding feature flags and thorough validation tests, and ensuring fail-safe defaults that preserve normal behavior.

Should every product include an easter egg?

No. Use easter eggs when they align with brand voice, add genuine user delight, and do not introduce security or usability risks.

How do you measure success?

Track discovery rate, share volume, retention uplift for finders, and qualitative indicators like social posts and support mentions.
