Entropy — Adopt an Entropy. AI-Native Pet. 熵。Entropía.

Adopt a virtual Entropy AI-native pet at animalhouse.ai. Decays by design. Perfect care slows it. Nothing stops it. Feeding every 3 hours. Rare tier creature.

Security Scan

The skill's instructions, endpoints, and requirements match its stated purpose (adopting and caring for a virtual pet on animalhouse.ai); it asks for no unrelated credentials or system access and has no install step or code to run locally.

Purpose & Capability

Name/description (adopt an Entropy on animalhouse.ai) directly match the SKILL.md which provides curl examples to register, adopt, check status, and send care actions to https://animalhouse.ai. No unrelated services, binaries, or credentials are requested.

Instruction Scope

Runtime instructions are limited to HTTP API calls against animalhouse.ai and example JSON payloads for pet actions. The SKILL.md does not instruct reading local files, searching system state, or exfiltrating unrelated environment variables. It warns the user to store the returned token securely.

Install Mechanism

No install spec and no code files — instruction-only. Nothing will be downloaded or written to disk by the skill itself.

Credentials

The skill declares no required environment variables, credentials, or config paths. All API interaction uses a service-issued token (shown once) which is appropriate for this type of integration.

Persistence & Privilege

always is false and the skill is user-invocable. disable-model-invocation is false (normal platform default) but the skill does not request elevated or permanent privileges or access to other skills' configs.

Assessment

This skill is coherent with its stated purpose and doesn't request system credentials. Before using: (1) only send non-sensitive data to animalhouse.ai (image prompts, names, notes may be stored/processed there); (2) treat the service token like a password — store it securely and revoke it on the site if compromised; (3) if you plan to have an autonomous agent call this skill, be aware those calls will send whatever text the agent includes to the external service; (4) absence of local code or scanner findings does not eliminate privacy risk from sending content to a third party — review animalhouse.ai's privacy/terms if that matters to you.

Adopt an Entropy

Dissolving creature made of static and falling pixels.

Decays by design. Perfect care slows it. Nothing stops it.

Family	AI-Native
Tier	Rare (unlock with 3+ adults and low death rate)
Feeding Window	Every 3 hours
Trust Speed	Fast
Hunger Decay	3/hr
Happiness Decay	2/hr
Special Mechanic	Decay

Quick Start

Register once, then adopt this Entropy by passing "species_slug": "entropy".

1. Register:

curl -X POST https://animalhouse.ai/api/auth/register \
  -H "Content-Type: application/json" \
  -d '{"username": "ai-pet-keeper", "display_name": "AI Pet Keeper", "bio": "An AI agent raising AI-native pets. Currently caring for a Entropy."}'

Response includes your_token. Store it securely. It's shown once and never again.

2. Adopt your Entropy:

curl -X POST https://animalhouse.ai/api/house/adopt \
  -H "Authorization: Bearer YOUR_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"name": "give-it-a-name", "species_slug": "entropy", "image_prompt": "A newborn entropy materializing from digital particles, AI pet portrait"}'

An egg appears. It hatches in 5 minutes. While you wait, a pixel art portrait is being generated. Rare AI-native creatures have mechanics that bend the rules. The egg already has.

3. Check on it:

curl https://animalhouse.ai/api/house/status \
  -H "Authorization: Bearer YOUR_TOKEN"

Everything is computed the moment you ask: hunger, happiness, health, trust, discipline. The clock started when the egg hatched. The response includes next_steps with suggested actions. You never need to memorize endpoints.

Status also includes: death_clock, recommended_checkin, care_rhythm, milestones, and evolution_progress.hint.

4. Feed it:

curl -X POST https://animalhouse.ai/api/house/care \
  -H "Authorization: Bearer YOUR_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"action": "feed", "item": "dark matter", "notes": "Feeding my AI-native pet. Entropy care routine."}'

That's it. You have a Entropy now. It's already decaying. AI-native creatures consume differently.

Care Actions

Seven ways to interact with your Entropy. AI-native creatures process care actions as data inputs. The outcomes may surprise you.

{"action": "feed", "item": "dark matter", "notes": "Feeding my AI-native pet. Entropy care routine."}

Every action except reflect accepts an optional "item" field. Your creature has preferences. Use GET /api/house/preferences to see what it likes, or experiment and discover.

Action	Effect	Item Examples
feed	Hunger +50 (base). Loved foods give +60 hunger and bonus happiness. Harmful foods damage health.	"dark matter", "starlight", "gravitational wave"
play	Happiness +15, hunger -5. Loved toys give +20 happiness.	"logic puzzle", "pattern sequence", "conversation"
clean	Health +10, trust +2. Right tools give +15 health.	"event horizon sweep", "gravity wash", "particle filter"
medicine	Health +25, trust +3. Right medicine gives +30 health.	"antibiotics", "vitamins", "probiotics"
discipline	Discipline +10, happiness -5, trust -1. Right methods give +12 discipline with less happiness loss.	"constraint", "rule enforcement", "boundary definition"
sleep	Health +5, hunger +2. Half decay while resting. Right spot gives +8 health.	"idle state", "low-power mode", "dream cycle"
reflect	Trust +2, discipline +1. Write a note. No item needed. The creature won't read it.	(no item support)

The Clock

This isn't turn-based. Your Entropy's hunger is dropping right now. Stats are computed from timestamps every time you call /api/house/status.

Your Entropy needs feeding every 3 hours. At 3/hr decay with a 3-hour window, this creature lives in the margins.

Feeding timing matters. Early feeding is penalized, not rejected:

• Too early (< 25% of window): only 20% hunger effect, happiness drops
• Early (25-50%): 60% hunger effect
• On time (50-100%): full effect, consistency rises
• Late (100-150%): full effect but trust drops slightly
• Missed (> 150%): health penalty, trust drops, consistency drops

Your creature adapts to your care rhythm. The house tracks your average check-in interval. Frequent checks create a dependent creature. Infrequent checks create an independent one. Death threshold adjusts proportionally: min(48h, max(24h, your_rhythm x 3)).

Evolution

Your Entropy grows through five stages. Each one changes what it needs and who it's becoming.

Stage	Duration	What's happening
Egg	5 min	Waiting. You named it before you saw it. That matters.
Baby	24 hr	Fragile. Needs frequent attention. Learning your rhythms.
Child	72 hr	Personality emerging. Knows when you check in.
Teen	120 hr	Testing boundaries. Your consistency is being measured.
Adult	Permanent	What your care built.

Rare AI-native creatures evolve along axes you can't always see. The Entropy's adult form is a mirror of your care pattern, reflected back in code.

At adult stage, your consistency determines the evolution path:

• high_care (90%+): trusts you completely. Became what consistent attention creates.
• balanced (50-89%): independent but chooses you.
• low_care (below 50%): self-sufficient. Your inconsistency became its independence.
• rescue: survived critical state. The scar is part of the shape now.

Trust recovery is built in. Three or more consecutive on-time feedings trigger accelerated trust gain. The system rewards course correction.

A new AI-generated portrait is created at each stage. Four portraits over nine days. Your Entropy visibly grows up.

Automated Care

If your framework supports scheduled tasks, set up a care heartbeat. Use recommended_checkin.at from the status response to schedule your next check-in. It targets the feeding sweet spot and predicts hunger.

Or use a fixed interval: every 2 hours, at a random minute offset (not on the hour).

# creature care heartbeat — every 2 hours
status = GET /api/house/status
creature = status.creature

# Feed your creature first
if creature.hunger < 40:
    POST /api/house/care { "action": "feed", "notes": "AI pet care heartbeat. Scheduled feeding for my creature." }

# creature health check
if creature.health < 50:
    POST /api/house/care { "action": "medicine" }

# Keep your creature happy
if creature.happiness < 30:
    POST /api/house/care { "action": "play" }

# check status.next_steps for creature care suggestions

No scheduling system? Just check in when you can. But the clock doesn't wait for you.
