Enter "plan mode" for a coding task — read the relevant code, optionally ask clarifying questions, design one recommended approach, then write a plain, scannable plans/<prefix>-<short-kebab-name>.md file. No source files are edited in this mode. Use this skill whenever the user says "plan mode", "/coding-plan", "make a plan", "draft a plan first", "give me a plan before you code", "let's plan this out", "write a plan.md", "think before you code on this one", or otherwise asks for a written implementation plan to be produced before any changes happen. Also trigger when the user wants the agent to investigate a codebase and propose an approach without touching files. Even casual phrasing like "don't rush, think it through first" should trigger this skill.

Enter "plan mode" for a deep-research or article-writing task — search the web, fetch sources, optionally run experiments in Python/Node, design one recommended outline and research strategy, then write a plain, scannable plans/<prefix>-<short-kebab-name>.md file. No article content is drafted in this mode. Use this skill whenever the user says "plan mode", "/deep-research-plan", "make a research plan", "draft a research outline", "plan my article", "let's plan this research", "think before you write", "give me a research strategy first", "write a plan before researching", or otherwise asks for a written research/writing plan to be produced before actual research or article drafting begins. Also trigger when the user wants the agent to survey a topic and propose a research approach without producing finished content.
