deep-research

deep-research is a skill for Claude Code from HezaoHezao/poirot. It costs 12 tokens per session (1,164 once invoked), scanned A, original, MIT.

A structured method for researching a topic through several searches, viewpoints, and levels of detail. It is intended for explanations, reports, presentations, and other work based on real-world information.

In plain words
What is it for?
Use it to investigate technologies, concepts, and current topics, or to gather material before writing a report, article, presentation, or explanation.
Why use it?
It reduces the risk of relying on one search result or unsupported assumptions. The process helps identify missing angles and compare information from multiple sources.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

deep-research scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Deep Research

Overview

Systematic methodology for thorough web research. Load this skill BEFORE starting any content generation task to ensure information from multiple angles, depths, and sources.

When to Use

Always load when:

  • User asks "what is X", "explain X", "research X", "investigate X"
  • User wants to understand a concept, technology, or topic in depth
  • A single web search would be insufficient to answer properly
  • Before creating presentations, reports, articles, or any content requiring real-world information

Core Principle

Never generate content based solely on general knowledge. A single search query is NEVER enough.

Research Methodology

Phase 1: Broad Exploration

Start with broad searches to understand the landscape:

  1. Initial Survey: Search for the main topic to understand overall context
  2. Identify Dimensions: From initial results, identify key subtopics, themes, angles needing deeper exploration
  3. Map the Territory: Note different perspectives, stakeholders, viewpoints

Phase 2: Deep Dive

For each important dimension identified, conduct targeted research:

  1. Specific Queries: Search with precise keywords for each subtopic
  2. Multiple Phrasings: Try different keyword combinations
  3. Fetch Full Content: Use browse_page to read important sources in full, not just snippets
  4. Follow References: When sources mention other resources, search for those

Phase 3: Diversity & Validation

Ensure comprehensive coverage by seeking diverse information types:

Information Type Purpose Example Searches
Facts & Data Concrete evidence "statistics", "data", "market size"
Examples & Cases Real-world applications "case study", "example", "implementation"
Expert Opinions Authority perspectives "expert analysis", "interview", "commentary"
Trends & Predictions Future direction "trends 2026", "forecast", "future of"
Comparisons Context and alternatives "vs", "comparison", "alternatives"
Challenges & Criticisms Balanced view "challenges", "limitations", "criticism"

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
