AD elective
PKU Course Selection (选课网) CLI tool built in Rust. Use this skill when working on the elective crate, debugging elective commands, adding features, or when the user mentions 选课, elective, course selection, auto-enroll, CAPTCHA solving, dual-degree, or elective.pku.edu.cn. Also use when dealing with CAPTCHA recognition backends (utool/ttshitu/yunma), automated course enrollment loops, or elective SSO callback. **NOT for general course schedule / 课表 / 这学期上什么课 questions — use the `treehole` skill (`treehole course`) instead, which gives a unified weekly grid with 主修+辅修+双学位. The `elective show` command only sees one program at a time and easily misses courses from the other program for dual-degree students.**
As a process D 48/100 · Unfinished process — 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 48/100
- 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 (elective) differs from the folder (pku-elective)
- 60Tools and files. Uses tools (bash) that frontmatter does not declare
- 100Steps. 20 steps
- 100When it triggers. States when to use and when not to
- 100Execution cost. Instruction body is 601 tokens
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.
