## How It Works

1. **Get Segment ID** — Use MCP (`CatalystbyZoho_List_Cache_Segments`) if available; otherwise retrieve it from the console or `.catalystrc`.
2. **Load `references/cache-basics.md`** — for SDK operations, TTL limits (48 hr max), and the `segment.delete()` / `segment.update()` gotchas.
3. **String values only** — All cache values are strings. Always `JSON.stringify` before `put` and `JSON.parse` after `get`.
4. **TTL behavior** — TTL is in HOURS (max 48), not seconds. `segment.update()` called WITHOUT an expiry argument silently resets the key's TTL to the 48-hour maximum (a 1-hour key becomes a 48-hour key). `segment.delete()` does not remove the key — it sets `cache_value` to `null` and the key persists; a later `getValue()` returns `null` with HTTP 200 and never throws.

## Triggers

Use this skill for: "Cache", "cache segment", "cache key", "cache value", "TTL", "in-memory store", `segment.get`, `segment.put`, `segment.delete`, "session data", "temporary data Catalyst", "cache vs Data Store", or "48-hour cache".
