AB spec-writer
Generate structured implementation spec documents for coding projects or features. Use when a user provides a requirement, feature idea, bug description, or GitHub issue and needs a spec before implementation. Produces a spec document covering objectives, user stories, technical plan, boundaries, verification criteria, and task breakdown — ready to hand off to a coding agent or human developer. Triggers on "write a spec", "draft a spec", "create an implementation plan", "spec this out", or any request to formalize requirements into a structured document. NOT for actually implementing code (use dev-workflow for that).
As a process B 79/100 · Nearly there — weak spots: 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 79/100
- 0Inputs and preconditions. Does not say what the process needs to start
- 0Failures and branches. Linear process with no failure handling
- 100Tools and files. No external tools needed
- 100Steps. 46 steps
- 100Result and completion. Output format and completion criterion are stated
- 100When it triggers. States when to use and when not to
- 100Consistency. Name and required fields are in place
- 100Execution cost. Instruction body is 1102 tokens
- 100Running it twice. No mutating operations
- 100Progress reporting. Reports progress
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.
