SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Ad-hoc web searches produce shallow answers with one or two sources and no audit trail, making it impossible to verify claims or trace them back to real sources. This Skill runs a structured L2 research pipeline that scrapes full source content, detects contradictions, and grades confidence per claim. ## Core Features & Use Cases - Composed research pipeline: Builds on the L1 /research skill, then adds a reflection loop with gap analysis, two follow-up sub-questions, and 10-15 additional scraped sources. - Contradiction detection and confidence grading: Explicitly surfaces disagreements between sources and labels every major claim as High, Medium, or Low confidence. - Verification checkpoints: Four mandatory Bash checkpoints verify that searches, scrapes, and summaries actually exist on disk, preventing hollow synthesis from search snippets. - Use Case: When deciding whether to migrate from one technology to another, run this Skill to get a ~2000-word report synthesizing 20-30 sources, with a dedicated contradictions section and per-claim confidence levels. ## Quick Start Ask the AI to run deep research on your question, for example: use deep research to compare PostgreSQL and MySQL for a high-write analytics workload.

Frequently Asked Questions about deep-research

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I run a deep research report with cited sources?▼

Invoke the deep-research skill with your query. It first runs the base research pass, then adds follow-up searches, scrapes 10-15 new sources with Firecrawl, and produces a ~2000-word report where every citation maps to a real bibliography entry.

What is the difference between research and deep-research tiers?▼

The base research tier (L1) takes about 5 minutes with 10-15 sources for standard overviews. Deep research (L2) adds a reflection loop, contradiction detection, and confidence grading, taking about 12 minutes with 20-30 sources for technology choices and comparisons.

Does deep research work without the Codex or Exa integrations?▼

Yes, the Codex cross-model channel and Exa neural search are optional and fault-tolerant. If they are not installed or are disabled via environment variables, the skill skips them silently and continues with the core Tavily and Firecrawl channels.

Why does the deep research skill require verification checkpoints?▼

The four checkpoints prevent hollow synthesis, a failure mode where the model writes a report from search snippets without actually scraping sources. Each checkpoint verifies that search results, scraped files, and summaries exist on disk before the pipeline proceeds.

When should I escalate from deep research to expert or academic research?▼

Escalate to expert-research (L3) for strategic decisions needing a critic agent and fact-checking, or to academic-research (L4) when you need scientific sources from arXiv and Scholar. Deep research suits comparisons and non-trivial investigations.
