What Grill does

Grill calibrates interrogation of a fuzzy idea before it becomes a spec, asking one question at a time and landing answers as goals or constraints. Use it when a plan is vague or needs stress-testing before writing a spec.

Grill is cataloged under Quality on DirSkills. Grill comes from a repository tagged claude-code, parallel-agents, skills, spec-driven-development and test-driven-development.

Documentation

README

Excerpt

grill — sharpen idea before spec

One question at a time. Every answer lands in a § or gets parked ?. Never guess a constraint into existence.

Plan-then-execute guesses the fuzzy parts & builds the wrong thing. Grill drags the fuzz into §G/§C before a single §T row exists. A bad assumption caught here costs one question. Caught in §B it costs a bug.

WHEN TO GRILL

Idea is one sentence & you can feel the holes.
Multiple readings of the goal exist & you are about to pick one silently.
Before /spec new on anything non-trivial.
User asks to be challenged / stress-tested.

Skip for a typo or a one-line fix. Grill scales to uncertainty, ⊥ to ego.
