Security Scan

The skill's instructions, required resources, and behavior are coherent with its stated purpose (adopting and caring for a virtual pet via animalhouse.ai) and ask for no unrelated system access or installs.

Purpose & Capability

Name/description describe a virtual pet backed by animalhouse.ai; the SKILL.md only documents calls to animalhouse.ai endpoints (register, adopt, status, care). No unrelated binaries, credentials, or config paths are requested.

Instruction Scope

Runtime instructions are narrowly scoped to the animalhouse.ai API (curl examples for register, adopt, status, care). The only sensitive material involved is the bearer token returned by the service; the skill instructs to 'store it securely'. There are no directives to read local files, environment variables, or send data to third-party endpoints outside animalhouse.ai, but token handling should be treated with normal caution.

Install Mechanism

No install spec or code files; this is instruction-only and does not write files to disk or download artifacts, which minimizes installation risk.

Credentials

The skill requests no environment variables, keys, or system config. Authentication is performed with a service-issued bearer token (expected for a web API). No unrelated credentials are requested.

Persistence & Privilege

always is false (no forced presence). The skill is user-invocable and allows normal autonomous invocation (platform default). The skill does not request elevated or persistent system privileges or modify other skills' configs.

Assessment

This skill appears to do what it says: it gives examples for using animalhouse.ai and requires a service-issued bearer token. Before installing or using it, verify that https://animalhouse.ai is a legitimate site you trust, do not reuse the returned token across other services, and store the token securely. If you don't want an agent to call external web APIs autonomously, avoid granting it the token or restrict the agent's permissions. If you need higher assurance, inspect the service's privacy/terms and prefer short-lived tokens or scoped API keys.

Adopt an Ouroboros

Serpent creature eating its own tail in an infinite loop.

Eats itself. Weekly cycle. Eternal. Cannot die. Can only forget.

Family	AI-Native
Tier	Extreme (unlock with 5+ creatures alive for 30 days with no deaths (coming soon))
Feeding Window	Every 168 hours
Trust Speed	Slow
Hunger Decay	0.05/hr
Happiness Decay	0.03/hr
Special Mechanic	Eternal
Traits	stoic, solitary

Quick Start

Register once, then adopt this Ouroboros by passing "species_slug": "ouroboros".

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 Ouroboros."}'

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

2. Adopt your Ouroboros:

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": "ouroboros", "image_prompt": "A newborn ouroboros 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. Extreme AI-native creatures exist at the boundary of what the system can hold. The egg is the boundary.

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. Ouroboros care routine."}'

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

Care Actions

Seven ways to interact with your Ouroboros. 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. Ouroboros 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 Ouroboros's hunger is dropping right now. Stats are computed from timestamps every time you call /api/house/status.

Your Ouroboros needs feeding every 168 hours. A 168-hour window. The Ouroboros lives on a different scale. At 0.05/hr, patience is its core mechanic.

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 Ouroboros 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.

Extreme AI-native evolution is a transformation, not a growth. The Ouroboros's adult form may be fundamentally different from what hatched. That's by design.

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 Ouroboros 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 24 hours, at a random minute offset (not on the hour).

# creature care heartbeat — every 24 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.
