What problem does it solve?
Deep-dive helps you investigate an unclear or evidence-heavy problem by first tracing the underlying causes and then turning the findings into a precise requirements specification instead of guessing.
Core Features & Use Cases
- Two-phase pipeline: runs a 3-lane causal trace (parallel hypotheses) and then performs a focused deep-interview to crystallize what to do next.
- 3-point injection: injects trace synthesis and lane-level critical unknowns into the interview so requirements building starts with evidence and uncertainty, not repetition.
- Brownfield/greenfield handling: detects whether you’re working with existing codebases and adapts the approach accordingly, including codebase context reuse.
- Evidence-structured outputs: produces both trace artifacts and a final spec containing a dedicated Trace Findings section.
Quick Start
Invoke deep-dive with your target problem statement, for example: /skill:deep-dive "Why does the production DAG fail intermittently on the transformation step?"
