Collaborative Brainstorming

Turn uncertainty into a useful choice or a focused experiment. Explore only the questions that could change the design. A clear implementation request already supplies direction; act on it without manufacturing a brainstorm or approval gate.

The user's instructions take precedence over this skill's guidelines. Preserve their constraints and existing authorization. Resolve routine design details with judgment; ask only when missing information materially changes the outcome and cannot be inferred.

Choose the Work Shape

Situation	Useful output
The user wants open exploration	Distinct directions with concrete tradeoffs and unresolved questions
The problem is clear but the mechanism is uncertain	A recommendation and the evidence that would overturn it
One assumption determines feasibility	A small test of that assumption before elaborating designs
The approach is selected and implementation is authorized	Continue into implementation
The user asks why something happens	Diagnose the cause before designing a fix

Ground the Question

Read the relevant code, artifact, or workflow and recall prior decisions. When Sibyl is configured, use its installed skill for current commands (sibyl context "<decision>" --intent plan). Memory supplies leads; inspect current evidence before reusing a volatile claim.
