AC portrait-compare
人脸识别与相似度比对 skill。当用户上传两张照片并询问"是否为同一个人"、"人脸相似度"、"人脸比对"、"人脸识别"、"两张图片是不是同一个人"，或需要计算两张人脸照片的相似度分数时，必须使用此 skill。 适用场景：人证比对、照片对比、身份核验、人脸匹配等任务。即使用户只是说"帮我看看这两张照片是不是同一个人"也应触发此 skill。
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 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 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. 5 steps
- 100Consistency. Name and required fields are in place
- 100Execution cost. Instruction body is 517 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.

This skill locally compares two face photos as advertised, but users should treat the images and generated result as sensitive biometric data.
