+# 88 — LLM agent chat
+
+## Goal
+
+Natural-language chat that acts on the app via tool-calling against the API, using a provider-agnostic OpenAI-compatible endpoint (self-hosted on the homelab).
+
+## Why
+
+Users should say "add milk to the shopping list" or "what's on the calendar Friday?" and have the agent use the API.
+
+## Depends on
+
+- 87 (API surface)
+- ADR `0006-api-llm-agent.md` agent half (MCP yes/no, tool mapping)
+
+## Scope
+
+- Agent chat UI in the app.
+- OpenAI-compatible client (provider-agnostic).
+- Tool-calling mapped to API endpoints from 87 (and journal if present).
+- Decide MCP vs direct tools in ADR 0006.
+- Smoke tests with **mock/stub** provider in CI — no live LLM in CI.
+
+## Out of scope
+
+- Training or fine-tuning models.
+- Forward-auth for other homelab apps.
+
+## Acceptance criteria
+
+- [ ] Chat UI sends prompts and shows responses.
+- [ ] Tools call the API successfully in dev against the homelab endpoint.
+- [ ] CI uses mock provider only.
+- [ ] ADR 0006 records provider and MCP decisions.
