AC auto-spec
Spec-driven development assistant: helps write precise behavioral specs before coding, or reverse-engineer specs from existing code for understanding and alignment. Use this skill when the user mentions "write a spec", "generate spec", "spec-driven", "behavioral contract", "reverse spec from code", "clarify this module's behavior", or "align on intent". Also applies when the user says "I want to add a feature, help me think it through first" or "what does this code actually do, walk me through it".
As a process C 64/100 · Has gaps — weak spots: result and completion, inputs and preconditions, progress reporting
How to improve
- A spec.yaml with trigger phrases and assertions — a behaviour contract for CI; `skilltest init` writes a template.

Process rating: all ten parameters 64/100
- 0Result and completion. Does not say what the result is
- 0Inputs and preconditions. Does not say what the process needs to start
- 0Progress reporting. Says nothing while it works
- 65Failures and branches. 3 branches
- 70When it triggers. States when to use, but not when not to
- 85Steps. 50 steps, 1 vague phrases
- 100Tools and files. No external tools needed
- 100Consistency. Name and required fields are in place
- 100Execution cost. Instruction body is 1604 tokens
- 100Running it twice. No mutating operations
- medium 3 test cases, all positive: not one "should refuse" or "should ask first"
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.
