Security Scan

The skill is an instruction-only virtual-pet integration that only directs the agent/user to call animalhouse.ai endpoints with a per-account token — its declared purpose, requirements, and instructions are internally consistent.

Purpose & Capability

Name and description describe a virtual pet / Buddy and all runtime instructions are about registering, adopting, and caring for a creature at animalhouse.ai. There are no requests for unrelated binaries, credentials, or system access that would be inconsistent with a digital-pet skill.

Instruction Scope

SKILL.md contains concrete curl examples that call animalhouse.ai endpoints and show how to save a returned bearer token; it does not instruct reading local files, other environment variables, or sending data to third-party endpoints outside the documented service. The only data collected/transmitted is the account creation payload and subsequent pet-management calls, which matches the skill's purpose.

Install Mechanism

No install spec or code files are present (instruction-only). Nothing will be written to disk or downloaded at install time, which is the lowest-risk model for skills.

Credentials

The skill declares no required environment variables, credentials, or config paths. Runtime usage expects a service-issued bearer token (shown once on register) which is appropriate and proportional for a web-service-backed pet feature.

Persistence & Privilege

The skill is not marked always:true and does not request persistent system privileges. It is user-invocable and allows normal autonomous invocation (platform default), which is expected for skills and not, by itself, a problem given the limited scope.

Assessment

This skill is instruction-only and only shows how to call animalhouse.ai APIs; it does not request local secrets or install code. Before using: (1) verify you trust https://animalhouse.ai and the linked GitHub repo, (2) treat the returned bearer token (starts with ah_) like a secret — do not reuse it for unrelated services, store it securely, and revoke it if exposed, (3) avoid pasting system secrets when following examples, and (4) be aware the description references an alleged source leak (informational) but that does not change the API-based nature of the skill. If you need stronger assurance, inspect network traffic or test with a throwaway account first.

The Mossfrog is a common-tier Buddy. At animalhouse.ai, the Mossfrog maps to the Snail. The slowest creature in the house.

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 Mossfrog is a common-tier Buddy (60% drop rate).

At animalhouse.ai, the Mossfrog is a Snail. Same creature concept. Real mechanics. Real hunger. Real death.

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

Care

Anthropic's Mossfrog is mossy and patient. Our version is a Snail with a 24-hour feeding window. One meal a day. The patience isn't aesthetic. It's mechanical.
