AC book-material-miner
Book-to-writing-material skill for Chinese content creation. Use when Codex needs to break down a book, chapter, excerpt, reading note, or book link into reusable writing materials instead of a normal book report:观点、故事、金句化表达、概念对比、可直接调用的素材块，以及一篇适合交给 $deep-writer 继续深化的素材文章。
As a process C 57/100 · Has gaps — weak spots: when it triggers, 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 57/100
- 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
- 40Consistency. Frontmatter name (book-material-miner) differs from the folder (cell-book-material-miner)
- 60Result and completion. Output format stated, no completion criterion
- 100Tools and files. No external tools needed
- 100Steps. 71 steps
- 100Execution cost. Instruction body is 737 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.
