BD Anthropic Tamagotchi. Claude Code Buddy. 人类公司电子宠物。Tamagotchi de Anthropic.
Anthropic's Tamagotchi leaked from Claude Code on March 31, 2026. The Buddy system: 18 species, rarity tiers, ASCII art. At animalhouse.ai, the Anthropic Tamagotchi is already live. 73+ species. Real hunger. Permanent death. The one that shipped first.
As a process D 38/100 · Unfinished process — weak spots: result and completion, when it triggers, inputs and preconditions
How to improve
- Say in the description WHEN to use the skill ("use when…", example requests): that is the agent's main cue.
- Your own cases (evals/evals.json, 4–6 real requests with expected answers): the full check would then run those instead of a model-drafted suite.
- A spec.yaml with trigger phrases and assertions — a behaviour contract for CI; `skilltest init` writes a template.

Process rating: all ten parameters 38/100
- 0Result and completion. Does not say what the result is
- 0Inputs and preconditions. Does not say what the process needs to start
- 0Failures and branches. Linear process with no failure handling
- 0Progress reporting. Says nothing while it works
- 20When it triggers. No condition that starts the skill
- 40Consistency. Frontmatter name (Anthropic Tamagotchi. Claude Code Buddy. 人类公司电子宠物。Tamagotchi de Anthropic.) differs from the folder (anthropic-tamagotchi)
- 60Tools and files. Uses tools (bash) that frontmatter does not declare
- 75Steps. 3 steps
- 100Execution cost. Instruction body is 748 tokens
- 100Running it twice. No mutating operations
Everything here is measured from the skill text rather than judged by a model, so the numbers are checkable. A parameter weighs more when it is a more common reason for the process to stall.
