当测试发现"这个功能测不了"、"加个日志就能定位"、"这个模块没法 Mock"时使用此技能。从可控性（能否控制测试条件）、可观察性（能否看到内部状态）、可隔离性（能否独立测试）、自动化性和可诊断性五个维度评估系统的可测试性水平，给出具体的系统改进建议和推动策略。可测试性差的系统一定质量差——不是因为系统本身不好，是因为你根本测不透它。输出可测试性评估报告和各维度的改造建议。 ⚠️ 本技能含废弃测试清理建议，执行前请确认非关键数据。 触发场景：可测试性、难测、不好测、测试推动、架构改进、可测性评审、需要推动架构改进可测试性时。 Use when the user asks about: assessing and improving system testability — controllability, observability, isolatability, automability, and diagnosability.

As a process C 59/100 · 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 59/100
- 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
- 70When it triggers. States when to use, but not when not to
- 100Tools and files. Tools declared in frontmatter
- 100Steps. 10 steps
- 100Consistency. Name and required fields are in place
- 100Execution cost. Instruction body is 347 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
- +4Description does not say when NOT to use the skill (false activations)
- +3Output format is not stated: the model decides each time
- +2Single-language instructions
- +5Description quotes 3 example trigger phrases
- +3Description length 421: enough signal without eating the budget
- +4Structure: 11 headings
- +3Step-by-step instructions: 10 items
- +4Has examples (3 code blocks)
- +4Reference files are cited in the instructions (1 of 1)
- +1License stated
Quality base 70; lint remarks subtract, signals add up to 100. Result: 94.
