AC calculator
高性能本地计算器技能，通过 Python 脚本提供数值计算能力。触发场景：(1) Agent 需要进行数学运算（四则、幂、三角、对数等）(2) 需要矩阵运算（乘法、求逆、行列式、特征值、SVD 等）(3) 需要统计分析（均值、标准差、回归、概率分布等）(4) 需要高精度/任意精度计算（大数运算、超越函数等）(5) 需要数值优化（求极值、求根）(6) 需要数值积分或微分方程求解 (7) 需要信号处理（FFT、卷积等）。当 Agent 自行计算可能出错或需要高性能计算库时应优先使用此技能。
As a process C 60/100 · Has gaps — weak spots: when it triggers, failures and branches, consistency

How to improve
- Say in the description WHEN to use the skill ("use when…", example requests): that is the agent's main cue.
For the model run — optional
- 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.

Against the Agent Skills spec
- warning
description-no-whendescription does not say WHEN to use the skill (no "use when")
Process rating: all ten parameters 60/100
- 0Failures and branches. Linear process with no failure handling
- 20When it triggers. No condition that starts the skill
- 40Consistency. Frontmatter name (calculator) differs from the folder (calculator-py)
- 60Tools and files. Uses tools (python) that frontmatter does not declare
- 60Result and completion. Output format stated, no completion criterion
- 70Inputs and preconditions. Inputs and preconditions are listed
- 100Steps. 15 steps
- 100Execution cost. Instruction body is 1427 tokens
- 100Running it twice. No mutating operations
- 100Progress reporting. Reports progress
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.
Quality signals
- +5Description has no quoted example phrases that should trigger the skill
- +4Description does not say when NOT to use the skill (false activations)
- +1No license
- +2Single-language instructions
- +3Description length 245: enough signal without eating the budget
- +4Structure: 16 headings
- +3Step-by-step instructions: 15 items
- +3Output format is stated explicitly
- +4Has examples (14 code blocks)
- +3All 2 scripts are documented
Quality base 70; lint remarks subtract, signals add up to 100. Result: 78.

This is a real local calculator skill, but its expression parser can execute local shell commands despite claiming that arbitrary code execution is not possible.
