save-plan

name	save-plan
description	Save the plan currently being discussed in the conversation to a markdown file in /tmp and open it in Neovim via nvr. Use when the user wants to persist the current plan/analysis/steps to a file they can edit, or mentions "save plan", "écris le plan", "dump plan to nvim".

Write the plan currently being discussed in the conversation to a markdown file in /tmp/, then open it in the user's running Neovim instance via nvr.

Steps

1. Extract the plan content from the current conversation. This is whatever plan, analysis, steps, or design you've been producing or refining with the user. Format as clean Markdown (headings, bullets, code blocks).

2. Generate a short kebab-case description (2-5 words) that summarises the plan's topic. Examples: ubuntu-migration, auth-refactor, statusline-icons.

3. Build the filename as /tmp/plan-<description>-<YYYYMMDD-HHMM>.md. Use date +%Y%m%d-%H%M for the timestamp.

4. Write the file with the Write tool — full Markdown content, no preamble ("Here is the plan…") and no closing summary.

5. Open in Neovim with:

   nvr --remote <file>
   

   This opens the file in a new buffer in the current tab. Do NOT use --remote-tab.

6. Report the absolute path back to the user in one short line. Nothing else.

Constraints

• Do NOT ask the user to confirm the filename or description — pick sensible values and proceed.
• Do NOT create the file outside /tmp/.
• Do NOT modify Neovim configuration or run any command other than nvr --remote.
• If nvr fails (e.g. no Neovim server running), report the file path and the error verbatim so the user can open it manually.
