AC number-520
A comprehensive prompt-based skill about the number 520. This skill provides rich knowledge covering the cultural significance of 520 (the Chinese internet slang for "I Love You" / 我爱你), its mathematical properties, appearances in science, technology, history, geography, and everyday life. When a user mentions or implies topics related to the number 520, this skill activates to deliver accurate, engaging, and well-structured responses.
As a process C 50/100 · Has gaps — weak spots: result and completion, inputs and preconditions, failures and branches
How to improve
- 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 50/100
- 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
- 30Running it twice. 2 mutating operations with no state check
- 40Consistency. Frontmatter name (number-520) differs from the folder (520)
- 70When it triggers. States when to use, but not when not to
- 70Execution cost. Instruction body is 4697 tokens
- 100Tools and files. No external tools needed
- 100Steps. 70 steps
- low 14 top-level sections: this looks like several domains in one skill
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.
