deep-research-plan

Enter plan mode for a deep-research or article-writing task. Use when the user asks for a written research plan, research outline, article plan, source strategy, experiment plan, deep research plan, /deep-research-plan, think before writing, write a plan before researching, or otherwise wants the agent to survey a topic and produce a plan file without drafting the finished article or report. This skill is read/search-only except for writing the selected plan file. Do not use for code implementation plans, immediate research execution, finished article/report drafting, product roadmap decisions, or conversational summaries without a plan artifact.
