What problem does it solve?
This Skill helps you safely investigate a blocked issue when the root cause, source behavior, or validation evidence is missing, so you can gather the minimum facts needed before implementing a change.
Core Features & Use Cases
- Bounded Investigation Planning: Defines a precise question, affected repository, search scope, command budget, and stop conditions before you start digging.
- Evidence Collection: Captures source facts, blockers, unknowns, and hints in a structured investigation note for later handoff or resumption.
- UI Runtime Troubleshooting: Guides targeted runtime checks for layout, host embedding, DOM ancestry, computed styles, box metrics, and scrollbar behavior when frontend parity issues are suspected.
- Routing Decision Support: Recommends whether the work should proceed as a micro-fix, standard bugfix, full SDD, validation-only pass, or remain blocked.
- Use Case: You are debugging a broken feature, but the failing condition is unclear and the current fix attempt did not help; use this Skill to collect proof and decide the safest next stage.
Quick Start
Use this skill to investigate the blocked feature, record the evidence in the required investigation file, and recommend the next stage before making another implementation change.
