# Co-Researcher

> A PhD-level research agent suite for Claude Code, Gemini CLI, OpenAI Codex, and OpenCode. Governed by Systemic Honesty — no fabricated citations, no hallucinated data.

This site is a live benchmark arena evaluating research agent performance across 22 test cases and 8 agent types.

## What Co-Researcher Does

Co-Researcher provides specialized research skills that run inside AI coding assistants. Each skill is a structured protocol enforcing academic rigor.

## Research Skills

- **Critical Analysis** — fallacy detection, bias identification, contradictory evidence handling
- **Literature Review** — systematic search, citation chaining, hallucination detection, gap analysis
- **Hypothesis Testing** — variable mapping, falsification criteria, experimental controls
- **Quantitative Analysis** — statistical method selection, effect size interpretation, Simpson's paradox detection
- **Qualitative Research** — thematic analysis, coding strategy, leading-question detection
- **Peer Review** — manuscript critique and methodological rigor scoring
- **Ethics Review** — IRB compliance, privacy risk assessment
- **Research Synthesis** — multi-source narrative synthesis with uncertainty quantification
- **Systematic Review** — PRISMA-standard protocol, Risk of Bias assessment
- **Grant Writing** — funding strategy, Specific Aims development
- **Lateral Thinking** — cross-domain analogies, constraint satisfaction, first-principles reasoning
- **Research Manager** — dynamic task scaffolding and polyglot session persistence
- **Academic Writing** — eliminating AI-isms from research prose
