Inspired by RhinoInsight: Improving Deep Research through Control Mechanisms for Model Behavior and Context

A structured research workflow skill for Claude Code, OpenCode, and Codex, supporting two-phase research: outline generation (extensible) and deep investigation. Human-in-the-loop design ensures precise control at every stage.

Use Cases

• Academic Research: Paper surveys, benchmark reviews, literature analysis
• Technical Research: Technology comparison, framework evaluation, tool selection
• Market Research: Competitor analysis, industry trends, product comparison
• Due Diligence: Company research, investment analysis, risk assessment

Installation

git clone https://github.com/Weizhena/deep-research-skills.git
cd deep-research-skills

Claude Code

# English version
cp -r skills/research-en/* ~/.claude/skills/

# Chinese version
cp -r skills/research-zh/* ~/.claude/skills/

# Required: Install agent and modules
cp agents/web-search-agent.md ~/.claude/agents/
cp -r agents/web-search-modules ~/.claude/agents/

# Required: Install Python dependency
pip install pyyaml

OpenCode (default: gpt-5.4)

# Skills (same as Claude Code)
cp -r skills/research-en/* ~/.claude/skills/   # or research-zh for Chinese

# Required: Enable web search for current shell
export OPENCODE_ENABLE_EXA=1

# Optional: make it permanent
echo 'export OPENCODE_ENABLE_EXA=1' >> ~/.bashrc
source ~/.bashrc

# Required: Install agent and modules
cp agents/web-search-opencode.md ~/.config/opencode/agents/web-search.md
cp -r agents/web-search-modules ~/.config/opencode/agents/

# Required: Install Python dependency
pip install pyyaml

Important: In OpenCode, ANY model's websearch requires OPENCODE_ENABLE_EXA=1. A plain export only affects the current shell; writing it to ~/.bashrc makes it persistent. Without it, you only get web fetch, which is weaker for the deep research phase.

Codex

# English version
mkdir -p ~/.codex/skills ~/.codex/agents
cp -r skills/research-codex-en/* ~/.codex/skills/

# Chinese version
mkdir -p ~/.codex/skills ~/.codex/agents
cp -r skills/research-codex-zh/* ~/.codex/skills/

# Required: Install web researcher agent and modules
cp agents-codex/web-researcher.toml ~/.codex/agents/
cp -r agents-codex/web-search-modules ~/.codex/agents/

# Required: Install Python dependency
pip install pyyaml

Add or update ~/.codex/config.toml using either method below:

Option A: Automatic script

cd deep-research-skills
bash scripts/install-codex.sh

Option B: Manual edit
