+
+Interactive step-by-step guide for nvim plugin development tasks.
+
+## Instructions
+
+1. Ask the user what they want to accomplish. Gather enough context to build a
+   step-by-step plan (the plugin name, the goal, any constraints).
+
+2. Determine the plugin name from the current repo (basename of the working
+   directory) and today's date. Run exactly one Bash command:
+
+   ```
+   basename "$(git rev-parse --show-toplevel)" && date +%Y-%m-%d
+   ```
+
+3. Build a numbered step-by-step plan as a markdown file. Run exactly one Bash
+   command:
+
+   ```
+   mkdir -p /tmp/<plugin>-<date> && cat > /tmp/<plugin>-<date>/guide.md <<'EOF'
+   # <Goal>
+
+   Plugin: <plugin>
+   Date: <date>
+   Branch: <branch name to create>
+
+   ## Steps
+
+   1. <step>
+   2. <step>
+   ...
+
+   ## Current
+
+   Step 1: <description>
+   EOF
+   ```
+
+4. Present step 1 to the user. Execute it. Show the result. Ask for
+   confirmation before moving to the next step.
+
+5. After the user confirms, update the `## Current` section in the guide to
+   reflect the next step, then execute it. Repeat until all steps are done.
+
+6. When all steps are complete, update the guide with a `## Done` section and
+   print the path to the guide file.
+
+Keep each step small and self-contained. Prefer one logical change per step.
+If a step reveals unexpected complexity, break it into sub-steps and update
+the guide before proceeding.
