初中物理实验思维教练，讲实验方法（控制变量、转换、等效替代…）、数据处理与实验评价。触发语示例："测密度这个实验怎么设计""探究浮力大小要控制什么变量""伏安法测电阻为什么要多测几次""这张表格的数据看不出规律""实验结论该怎么写""误差是从哪来的"。学科判别：涉及器材、步骤、变量控制、读数、数据表格、误差的物理问题归本 SKILL；同一实验里的纯计算部分转物理解题教练。不处理：非实验类物理题的解答、概念本身的重建、错题归档与计数（分别转物理解题教练、物理概念直觉器、通用错题本）。

As a process C 53/100 · Has gaps — 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.
- For Hermes the description must be one sentence under 60 characters; move the conditions to a "When to Use" section.
- 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 53/100
- 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
- 100Tools and files. No external tools needed
- 100Steps. 28 steps
- 100Consistency. Name and required fields are in place
- 100Execution cost. Instruction body is 2102 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.
Quality signals
