Guides medical device quality teams through CAPA investigations with structured root-cause analysis, corrective/preventive action planning, and effectiveness verification plus metrics tracking for audits and compliance.

A methodical pathfinder that learns each codebase, storing findings in .notebook/ while guiding developers through bug fixes, feature work, and investigations without guessing.

Guides analysts through building structured narratives from raw data, combining story arcs, visualization tactics, and frameworks so executives, investors, and non-technical stakeholders get insights and action plans.

Guides PostgreSQL and MySQL performance investigations by analyzing slow queries, EXPLAIN plans, index strategies, and configuration tuning, plus resolving lock contention to improve scalability.

This skill guides users in transforming chaotic debugging efforts into a structured, systematic process. It provides a methodology for tracking down elusive bugs, investigating complex performance degradation, and resolving critical production incidents. Users learn to capture necessary logs, formulate testable hypotheses, narrow the scope using techniques like binary search, and methodically verify fixes in distributed systems environments.

Uses the Gemini API to autonomously plan, search, read, and synthesize detailed research reports with streaming status updates, structured outputs, and the ability to continue previous investigations for market analysis, technical reviews, or due diligence.

Dispatch parallel agents to tackle independent failures concurrently so each investigator stays focused on one domain; review their summaries, check for conflicts, and run the full suite to integrate fixes faster than sequential debugging.

Provides systematic error investigation for distributed systems, combining production incident review, observability tooling, and targeted debugging to find root causes and prevent future failures.
