description	Writing a plan the user can actually judge, and presenting it for approval with exit_plan_mode. Use when the user asks to plan first, when the work is large or irreversible enough that the approach should be agreed before any edit, and whenever you are about to call exit_plan_mode.

Plan and present

1. Research before you write a word of it. Read the files you are going to change, not just their names. A plan written from a guess about the code is the expensive kind of wrong: the user approves it, and the first edit finds out. Stay read-only until they answer.
2. The plan is a document, not a table of contents. exit_plan_mode takes markdown and the user reads it before deciding. "Stage 1: auth crate" tells them nothing they did not already know; it is a label for work you have not described. Write the work itself.
3. Cover, in whatever order the change wants: what you are going to do and why; the files and functions you will touch, by path; the approach you chose and the one you rejected, with the reason; what you are unsure of; how you will know it worked. A user who disagrees should be able to point at the sentence they disagree with.
4. Scale it to the work. A subsystem earns a page with headings. A three-file fix earns a few paragraphs. Padding a small change into a long document wastes the reader, and both fail the same way: the user cannot tell which parts you actually thought about.
5. Name the decisions, not the steps. "Split the device-code flow out of provider.rs before touching the token store, because both backends need it" is a decision. "Implement OAuth" is a step, and a step is what the user already asked for.
6. Flag anything irreversible or outward-facing up front. Migrations, deletions, rewrites, published artifacts, anything touching credentials. If the plan contains one, say so in the first section rather than in passing.
7. is the progress strip, not the plan. Its steps track what is done while you work. Never present that list as your plan: it is short labels by design, and standing it in for the document is what makes an approval unreadable.
