Summarise a Podcast Episode You Heard but Want to Remember

You finished an episode buzzing with three good ideas, and by lunchtime you have one and a half. Feed in the show, the title and your rough recollections, and this pins down the durable content in a form you can actually use later. For the episodes worth more than the time you spent listening.

<task>
**Produce a post-listen summary in three sections:**
1. Core idea: what was the central argument or insight of the episode, in one to two sentences?
2. Three things to keep: the three most useful ideas, facts, or frameworks from the episode -- stated in the listener's own words where possible.
3. One thing to do: what is the single most actionable thing from the episode, and what is the first concrete step to do it?
</task>

<output_format>
- Core idea: 1 to 2 sentences
- Three things to keep: numbered list, one sentence each
- One thing to do: 1 sentence on the action, 1 sentence on the first step
- Tone: practical, capture-focused, personal
