Navigate the topic taxonomy. Without parent_slug, returns the top-level roots (Politics, Business, Technology, etc.). With parent_slug set, returns the direct children of that topic. Topic slugs use a parent/child convention (e.g. politics/elections) and let agents browse the hierarchy to find well-named categories. The slugs round-trip into the topic_slug filter on particle_podcast_resolve and particle_podcast_list_guests, and appear on episodes via particle_podcast_get_episode with include: ["topics"].

Output

A markdown document with an ## Topics (N) heading and a flat bullet list — one bullet per topic, formatted **Name** — slug: <slug> (with — <ancestry> appended when an ancestry path is available). When more pages exist, a horizontal rule and a **Cursor:** <value> line are appended; pass that cursor value back as the cursor input. Sample (limit=5): 
## Topics (5)

- **Society** — slug: society
- **Government** — slug: government
- **Business** — slug: business
- **Politics** — slug: politics
- **Media** — slug: media
---

**Cursor:** r.4gfFC9
The string after slug: is what you pass back as parent_slug to drill into a topic’s children.

Example

Agent calls: particle_topic_browse {}
            → reads "slug: politics" → "politics"

Agent calls: particle_topic_browse { "parent_slug": "politics" }
            → returns child topics like "politics/elections"
