-### Providers
+### Provider
 
-Model names use a `provider/model` prefix scheme:
+The `agent.provider` field is **required** and must be one of:
 
-| Prefix | Provider | Example |
+| Provider | Description |
-|--------|----------|---------|
+|----------|-------------|
-| `anthropic/` | Anthropic direct | `anthropic/claude-opus-4-5` |
+| `anthropic` | Anthropic direct (Claude models) |
-| `openai/` | OpenAI direct | `openai/gpt-4o` |
+| `openai` | OpenAI direct (GPT models) |
-| `google/` | Google direct | `google/gemini-2.5-pro` |
+| `google` | Google direct (Gemini models) |
-| `openrouter/` | OpenRouter (any model) | `openrouter/anthropic/claude-sonnet-4-5` |
+| `openrouter` | OpenRouter (access to many models) |
-| `ollama/` | Local Ollama | `ollama/llama3.2` |
+| `ollama` | Local Ollama instance |
 
-For Ollama, set `providers.ollama.apiBase` (default: `http://localhost:11434/api`).
+The `agent.model` field is also **required** and should be the model ID without any provider prefix:
+
+| Provider | Example Model |
+|----------|---------------|
+| `anthropic` | `claude-sonnet-4-5`, `claude-opus-4-5` |
+| `openai` | `gpt-4o`, `gpt-4o-mini` |
+| `google` | `gemini-2.5-pro`, `gemini-2.0-flash` |
+| `openrouter` | `anthropic/claude-sonnet-4-5` (OpenRouter uses its own model IDs) |
+| `ollama` | `llama3.2`, `qwen2.5` |
+
+For Ollama, set `providers.ollama.apiBase` (default: `http://localhost:11434`).

 ## Key Decisions Made
 - Mattermost channel uses raw WebSocket + fetch (no mattermostdriver, no SSL hack)
 - No MCP support (use shell tools / CLI instead)
 - No reasoning/thinking token handling (can add later)
 - Config is fresh Zod schema (no migration from Python config needed)
-- `ollama-ai-provider` package (not `@ai-sdk/ollama` which 404s on npm)
+- `ai-sdk-ollama` package for Ollama provider (replaced old `ollama-ai-provider`)
 - `strArg(args, key, fallback?)` helper exported from `agent/tools/base.ts` for safe unknown→string extraction
+- Agent config requires explicit `provider` field (no more model prefix like "anthropic/claude-...")
+- Model names are now just the raw model ID (e.g., "claude-sonnet-4-5" not "anthropic/claude-sonnet-4-5")
