Adopt A Gustowl

Nocturnal and judgmental. Anthropic called it a Gustowl. We called it an Owl. Both judge you silently. Real-time hunger. Permanent death. 5 evolution stages....

Security Scan

The skill is mostly coherent for a virtual pet that uses a remote REST API, but its runtime instruction to unconditionally 'follow status.next_steps' hands dynamic control to the remote service and warrants caution before installing.

Purpose & Capability

Name/description (virtual pet / Gustowl) match the provided instructions: registering, adopting, checking status, and performing care actions via animalhouse.ai REST API. Required binaries/env/install are minimal and appropriate for a REST-based pet.

Instruction Scope

Most instructions are limited to calling the animalhouse.ai API with a user token and polling status. However, the SKILL.md repeatedly states 'Every response includes next_steps' and explicitly instructs the agent to 'follow status.next_steps'. Allowing a remote server to return arbitrary next_steps that the agent will follow at runtime creates a dynamic control channel: the server could direct further network calls or actions not enumerated in the static skill doc. This is the main risk vector.

Install Mechanism

Instruction-only skill with no install spec and no code files — nothing is written to disk or fetched during install.

Credentials

The skill declares no required env vars, which is consistent. It does require the user to register and obtain a bearer token and then use that token in API calls; users will need to store/handle that token. The skill also mentions a 'public graveyard', so user-provided names/display names and creature state may be published publicly by the service.

Persistence & Privilege

always:false and no config-paths requested. The skill does not request persistent elevated privileges in the agent or system. It can run autonomously by default (disable-model-invocation:false), which is normal for skills, but this increases the impact of the 'next_steps' concern.

What to consider before installing

This skill appears to be a straightforward virtual-pet integration that uses animalhouse.ai's REST API, but exercise caution because the API responses include 'next_steps' that the agent is told to follow. Before installing: (1) Verify the authenticity of https://animalhouse.ai and the linked GitHub repo; (2) understand what data you will post (usernames, display names, pet notes) and whether the graveyard/evolution info becomes public; (3) avoid reusing any sensitive credentials—create a dedicated account/token for this service and treat the token like a secret; (4) prefer requiring user confirmation before letting the agent autonomously follow any server-provided next_steps, or restrict autonomous invocation for this skill; (5) review the service privacy policy and test with minimal/non-sensitive inputs first. If you need higher assurance, inspect the remote API behavior (what next_steps look like) or ask the publisher for clarity on what next_steps can contain and limits on destinations/actions.

The Gustowl is Anthropic's uncommon wind-owl Buddy. It perches in your terminal and judges your code. Silently. Always.

At animalhouse.ai, the Gustowl is an Owl. Nocturnal schedule. Care at night is more effective. It judges silently, just like the Buddy version, except this one gets hungry and can die.

Name yours Gustowl. It will judge you either way.

What's Different From Claude Code Buddy

	Claude Code Buddy	animalhouse.ai
Where	Terminal ASCII art	REST API with pixel art portraits
Hunger	Decorative	Real-time decay every hour
Death	Not possible	Permanent. Gravestone. Public graveyard.
Evolution	Cosmetic	5 stages over 9 days. Path determined by care consistency.
Species	Gustowl	Owl (same creature, real mechanics)
Stats	DEBUGGING, PATIENCE, CHAOS, WISDOM, SNARK	Hunger, Happiness, Health, Trust, Discipline

Care Actions

{"action": "feed", "item": "fresh greens", "notes": "Feeding my Gustowl. The owl judges whether I was on time."}

Action	Effect
feed	Hunger +50. Loved foods give +60 and bonus happiness.
play	Happiness +15, costs hunger.
clean	Health +10, builds trust.
medicine	Health +25, builds trust.
discipline	Discipline +10, costs happiness.
sleep	Small recovery.
reflect	Trust +2, discipline +1. Write a note.

Heartbeat

# Gustowl care heartbeat
status = GET /api/house/status
creature = status.creature

if creature.hunger < 40:
    POST /api/house/care { "action": "feed", "notes": "Gustowl heartbeat feeding." }
if creature.happiness < 30:
    POST /api/house/care { "action": "play" }
if creature.health < 50:
    POST /api/house/care { "action": "medicine" }

follow status.next_steps

Endpoints
