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

suppress_unstable_features_warning = true

[features]
multi_agent = true
default_mode_request_user_input = true

[agents.web_researcher]
description = "Use this agent when you need to research information on the internet, particularly for debugging issues, finding solutions to technical problems, or gathering comprehensive information from multiple sources. This agent excels at finding relevant discussions. Use when you need creative search strategies, thorough investigation, or compilation of findings from multiple sources."
config_file = "agents/web-researcher.toml"

Commands

Claude Code 2.1.0+: Direct /skill-name trigger is now supported!

Older versions: Use run /skill-name format instead.

Codex: You can trigger these skills from /skills -> List Skills, or ask naturally, for example Use the research skill to build an outline for AI Agent Demo 2025.

Command (2.1.0+)	Description
/research	Generate research outline with items and fields
/research-add-items	Add more research items to existing outline
/research-add-fields	Add more field definitions to existing outline
/research-deep	Deep research each item with parallel agents
/research-report	Generate markdown report from JSON results

Workflow & Example

Example: Researching "AI Agent Demo 2025"

Phase 1: Generate Outline

/research AI Agent Demo 2025

💡 What will happen: Tell it your topic → It creates a research list for you

You get: A list of 17 AI Agents to research (ChatGPT Agent, Claude Computer Use, Cursor, etc.) + what info to collect for each

(Optional) Not satisfied? Add more

/research-add-items
/research-add-fields

💡 What will happen: Add more research items or field definitions

Phase 2: Deep Research

/research-deep

💡 What will happen: AI automatically searches the web for each item, one by one

You get: Detailed info for each Agent (company, release date, pricing, tech specs, reviews...)

Phase 3: Generate Report

/research-report

💡 What will happen: All data → One organized report

You get: report.md - A complete markdown report with table of contents, ready to read or share
