deep-research

Use this skill instead of WebSearch for ANY question requiring web research. Trigger on queries like "what is X", "explain X", "compare X and Y", "research X", or before content generation tasks. Provides systematic multi-angle research methodology instead of single superficial searches. Use this proactively when the user's question needs online information.

About deep-research

A systematic methodology for conducting thorough web research, meant to replace single, superficial searches with a structured, multi-angle process. The guidance is loaded before any research question or content-generation task, such as writing articles, building presentations, designing UI mockups, or producing multimedia, so that output is grounded in gathered evidence rather than general knowledge alone. The core principle is that a single search query is never enough, and that output quality depends directly on the depth and breadth of prior research.

The workflow moves through four phases. Broad exploration surveys the main topic and maps its dimensions, stakeholders, and viewpoints. Deep dive runs targeted queries for each dimension, tries multiple phrasings, and uses web_fetch to read the most authoritative sources in full rather than relying on snippets. Diversity and validation deliberately seek different information types: facts and data, real-world examples, expert opinions, trends, comparisons, and criticisms, to build a balanced picture. A synthesis check then confirms coverage across at least three to five angles before any content is written.

Practical guidance covers effective query patterns that add specificity and source hints, temporal awareness that reads the current date and chooses month-, day-, or year-level precision to match intent, and when to fetch full pages versus scanning results. It lists common mistakes to avoid, such as stopping after one or two searches, ignoring contradicting viewpoints, or generating content before research is complete. A quality bar defines when research is sufficient: when key facts, concrete examples, expert perspectives, current trends, and limitations can all be answered confidently.

FAQ

When should I load this skill?

Load it before any question needing web research, such as 'what is X', 'explain X', or 'compare X and Y', and before content-generation tasks like slides, articles, or UI mockups that rely on real-world information. It is meant to be used proactively whenever a single search would be insufficient.

What are the four research phases?

Broad exploration to map the topic, deep dive with targeted queries on each dimension, diversity and validation across different information types, and a synthesis check to confirm coverage before writing.

Does it rely on search snippets alone?

No. It explicitly directs you to use web_fetch to read the most relevant and authoritative sources in full, since snippets are considered insufficient for data, case studies, or expert analysis.

How does it handle time-sensitive queries?

It reads the current date from context and matches temporal precision to intent: month-plus-day for 'today', a week range for 'this week', month for 'recently', and year for 'trends'. It warns against dropping to year-only when day-level precision is needed.

How do I know when research is complete?

The quality bar is met when you can confidently state the key facts and data, two or three concrete examples, expert perspectives, current trends, and the challenges or limitations of the topic.
