# Research
Use this skill when answering questions that require current facts, comparing tools, investigating docs, or grounding a recommendation.
## Workflow
1. Use `web_search` to find candidate sources.
2. Use `fetch_url` for primary sources and official documentation.
3. Use `read_file` for local repo context before applying external guidance.
4. Summarize what is known, what is inferred, and what remains uncertain.
## Standards
- Prefer official docs, source repositories, standards, and primary research.
- Do not overquote sources.
- If the answer could be outdated, use web tools.
- For implementation work, translate findings into concrete repo changes.
