# What's Next

> Planned features and capabilities coming to Mantle.

These features are designed but not yet built. Some already appear in
`integrations.yml` as configuration that parses and validates without a runtime
consumer; those are called out below.

## Responses and questions

**Variant selection** by channel. Multiple variants are already
parsed; only the first is used today.

**`ask_<memory_entry>` hooks** for dynamically generated questions, so a skill
can compute the wording of a `collect:` prompt at runtime.

## Integrations

**Knowledge stores.** `knowledge_stores:` (Qdrant, Milvus, external FAISS)
validates but is never queried. Today `search_knowledge` reads only the local
index built from `references/**/*.md`.

**Per-skill retrieval scoping**, so a skill's own `references/` are searched
ahead of, or instead of, the shared index.

**Tracker store** (Postgres, etc.) for persistent conversation state, and
**event broker** (Kafka, etc.) for streaming conversation events.

## Tool control flow

**`ToolResult.next`** is defined but not executed: returning `RunTool(...)` or
`ActivateSkill(...)` is currently a no-op. Executing them is planned.

## Remote tool hosting

**`rasa run tools`** will spin up a dedicated tool server that the runtime
connects to over MCP, letting you host tools separately.

**MCP extras.** `pre_call_hook` and `meta_map.from_slots` are not supported.
Use `meta_map.static` for per-call `_meta`.

## Agent-to-agent

**A2A skill exposure** will let you expose a skill so other agents can invoke it
over the A2A protocol.
