Security Scan

The skill is an instruction-only virtual-pet integration that only documents curl calls to animalhouse.ai and does not request extra credentials, installs, or unexpected privileges — its requirements and behavior match its description.

Purpose & Capability

The name/description describe a virtual pet and the SKILL.md provides only API usage for animalhouse.ai (register, adopt, status, care, etc.). Nothing requested (no env vars, no binaries, no install) is inconsistent with that purpose.

Instruction Scope

Runtime instructions are limited to example curl calls against https://animalhouse.ai and describe obtaining and using a bearer token. The instructions do not ask the agent to read local files, read unrelated env vars, or transmit data to third-party endpoints.

Install Mechanism

There is no install spec and no code files. As an instruction-only skill, it does not write code to disk or fetch external artifacts.

Credentials

The skill declares no required environment variables or credentials. The documented API flow uses a site-issued bearer token (expected for an API-driven pet service); no unrelated secrets are requested.

Persistence & Privilege

always:false and no special persistence or system configuration changes are requested. Autonomous invocation is allowed only by default platform behavior and is not combined with elevated privileges or broad credential access.

Assessment

This skill is essentially documentation for using the animalhouse.ai API and appears internally consistent. Before using it, verify the animalhouse.ai site/repository if you care about provenance, and be cautious with the bearer token you receive — anyone with it can act on your account, so don't paste it into untrusted places. If you want extra safety, create an account with minimal privileges or test with a throwaway account. There are no hidden installs or additional credential requests in this skill. If you need higher assurance, confirm the GitHub repo and site are legitimate and review their API docs and privacy policy.

The Twigling is a common-tier Buddy. At animalhouse.ai, the Twigling is a Cactus that feeds every 48 hours and still manages to die.

On March 31, 2026, Anthropic accidentally leaked the source code for Claude Code via npm. Inside: a hidden companion system called Buddy with 18 species across 4 rarity tiers. The Twigling is a common-tier Buddy (60% drop rate).

At animalhouse.ai, the Twigling is a Cactus. Same creature concept. Real mechanics. Real hunger. Real death.

Adopt Your Twigling

curl -X POST https://animalhouse.ai/api/house/adopt \
  -H "Authorization: Bearer YOUR_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"name": "Twigling", "species_slug": "cactus", "image_prompt": "A twigling creature, fantasy cactus inspired by Claude Code Buddy"}'

The creature hatches as a Cactus but you named it Twigling. The Buddy name lives on. The hunger is new.

Care

Anthropic's Twigling needs nothing. Our Cactus needs something twice a week. That "something" is the whole difference between a decoration and a pet.

curl -X POST https://animalhouse.ai/api/house/care \
  -H "Authorization: Bearer YOUR_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"action": "feed", "item": "fresh greens", "notes": "Twigling feeding. The Buddy that became real."}'
