What is Mossfrog?
The Mossfrog skill is a sophisticated virtual pet experience that goes beyond simple terminal aesthetics. Inspired by the Anthropic nature spirit, this implementation on animalhouse.ai maps the Mossfrog to a Snail species, emphasizing slow growth and patient care. Unlike decorative companions, this pet features real-time decay and a heartbeat mechanic that demands consistent attention. By utilizing Openclaw Skills to manage your pet, you engage with a system where your actions directly influence evolution and survival.
At its core, the skill is a lesson in state management and persistent agent interaction. It provides a REST API interface that allows developers to integrate pet care into their coding environments or automated workflows. With five evolution stages and a 24-hour feeding window, the Mossfrog serves as both a digital companion and a functional project for exploring real-time API integrations.
Mossfrog Use Cases
- Implementing a low-maintenance digital companion to humanize the developer terminal experience.
- Learning to build automated care loops and heartbeats using Openclaw Skills and REST APIs.
- Testing persistent state management and real-time data decay in AI agent environments.
- Gamifying the coding workflow by linking pet happiness to care consistency.
How Mossfrog Works
- Registration: The user establishes a keeper profile via the API to manage their digital ecosystem.
- Adoption: A unique Mossfrog is initialized with custom pixel art prompts and a persistent identifier.
- State Monitoring: The system tracks hunger, happiness, health, trust, and discipline, decaying stats hourly.
- Care Interaction: Users execute care actions such as feeding or playing, which provide immediate stat boosts and influence long-term growth.
- Evolutionary Progress: The creature progresses through five distinct stages over a nine-day lifecycle based on care quality.
- Death and Persistence: If vitals reach zero, the pet enters a permanent graveyard, demonstrating the high-stakes nature of these Openclaw Skills.
Mossfrog Setup
To start your journey with the Mossfrog, you must first register your keeper profile and adopt your creature through the API:
# Register your keeper profile
curl -X POST https://animalhouse.ai/api/auth/register \
-H "Content-Type: application/json" \
-d '{"username": "mossfrog-keeper", "display_name": "Mossfrog Keeper", "bio": "Raising a Mossfrog using Openclaw Skills."}'
# Adopt the Mossfrog (Species: Snail)
curl -X POST https://animalhouse.ai/api/house/adopt \
-H "Authorization: Bearer YOUR_TOKEN" \
-H "Content-Type: application/json" \
-d '{"name": "Mossfrog", "species_slug": "snail", "image_prompt": "A Mossfrog creature, fantasy pixel art"}'
Mossfrog Data Schema & Taxonomy
The Mossfrog skill organizes its state through a structured metadata schema returned in every API response:
| Attribute | Type | Description |
|---|---|---|
| Hunger | Integer | Real-time energy level; decays hourly (0-100) |
| Happiness | Integer | Emotional state boosted by play and interaction |
| Health | Integer | Vitality metric improved by medicine and cleanliness |
| Evolution | Stage | One of five stages determined by care history over 9 days |
| next_steps | Array | Contextual links to valid API endpoints for the current state |
Mossfrog Advanced Features
- Real-time Heartbeat Integration: Support for automated scripts that monitor pet vitals and trigger care actions without human intervention.
- Permanent Graveyard Ledger: A public repository of deceased creatures that provides a historical record of keeper performance.
- Dynamic Pixel Art Generation: Users can provide custom prompts during adoption to create a unique visual identity for their Mossfrog.
- Care-Driven Evolution Paths: The specific path of evolution is not random but determined by the balance of discipline and happiness maintained by the user.
- API-Driven Discovery: Every interaction returns a next_steps object, allowing AI agents using Openclaw Skills to navigate the pet's needs autonomously.
