AB book-writing-assistant
A complete writing companion for book authors covering both fiction and nonfiction. Tracks characters, plot threads, chapter outlines, research, world-building, and continuity. Also brainstorms, drafts passages, and helps with writer's block. Use this skill whenever someone mentions writing a book, novel, memoir, story, chapter, manuscript, character development, plot outline, world-building, or any long-form writing project. Trigger on casual phrases too -- "I'm working on my book," "I need to flesh out this character," "help me outline chapter 5," "what did I say about the setting in chapter 2," or "I'm stuck on this scene" should all activate this skill.

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 79/100
- 0Inputs and preconditions. Does not say what the process needs to start
- 60Result and completion. Output format stated, no completion criterion
- 70Failures and branches. 4 branches
- 70Execution cost. Instruction body is 4220 tokens
- 100Tools and files. No external tools needed
- 100Steps. 78 steps
- 100When it triggers. States when to use and when not to
- 100Consistency. Name and required fields are in place
- 100Running it twice. Mutating operations check current state
- 100Progress reporting. Reports progress
- medium Safety rules and hard prohibitions inside a skill: they belong in the system prompt, here they protect nothing
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.
