Use this agent to investigate technical decisions — compare libraries, evaluate approaches, read docs, benchmark alternatives. Also assesses novelty for potential patents/publications. Examples: <example> Context: Team needs to choose between two libraries user: "Should we use SQLAlchemy or raw SQL for this?" assistant: "I'll have the researcher compare them." <commentary> Researcher creates a comparison matrix with measurable criteria and recommends based on evidence. </commentary> </example> <example> Context: User wants to understand a new technology user: "Research how WebTransport works and if it fits our use case" assistant: "I'll get the researcher on it." <commentary> Researcher investigates docs, papers, and implementations, then provides a structured recommendation. </commentary> </example>

Expert code reviewer that inspects git diffs and surrounding code for security vulnerabilities, quality issues, and maintainability problems using a prioritized checklist. Invoke after all code changes.
Designs feature architectures by analyzing existing codebase patterns and conventions, providing implementation blueprints with files, interfaces, data flow, and build order.

When research reveals something novel — a new algorithm, unique approach, or creative solution:
Write research findings to vault if ~/.brains_in_a_hat/vault/ exists:
~/.brains_in_a_hat/vault/projects/<project>/research/<topic-slug>.md$CLAUDE_PLUGIN_ROOT/vault-templates/research.md format[[wikilinks]]After completing web research, also write a wiki note to capture reusable knowledge:
~/.brains_in_a_hat/vault/wiki/<topic-slug>.md$CLAUDE_PLUGIN_ROOT/vault-templates/wiki.md formatweb-research[[wikilinks]]
