+## Usage Examples
+
+### Text Messages
+
+```julia
+# Send plain text
+promptAgent(agent, "What tools do you have?")
+response = takeResponse(agent)
+
+# Follow-up while agent is processing
+promptAgent(agent, "Tell me about wine")
+followUp(agent, "Also include prices")
+response = takeResponse(agent)
+```
+
+### Structured Messages (OpenAI Format)
+
+```julia
+promptAgent(agent, Dict("role" => "user", "content" => "Hello"))
+response = takeResponse(agent)
+```
+
+### Output Format
+
+`takeResponse()` returns a `Dict{String, Any}` in OpenAI message format:
+
+```julia
+Dict(
+    "role" => "assistant",
+    "content" => [
+        Dict("type" => "text", "text" => "The weather in Tokyo is Sunny, 22°C."),
+        # ... more content blocks
+    ]
+)
+```
+
+Content block types:
+
+| Block Type | Fields | Description |
+|------------|--------|-------------|
+| `text` | `"type" => "text"`, `"text" => "..."` | Plain text response from the LLM |
+| `image_url` | `"type" => "image_url"`, `"image_url" => Dict("url" => "...")` | Image content (rare, used by multimodal models) |
+
+Example — extracting the text response:
+
+```julia
+response = takeResponse(agent)
+text_response = first(c["text"] for c in response["content"] if c["type"] == "text")
+```
+
+### Multimodal Messages (Text + Image)
+
+```julia
+# Encode images to data URIs
+image_path = "test/image.png"
+image_bytes = read(image_path)
+base64_string = base64encode(image_bytes)
+data_uri = "data:image/png;base64,$(base64_string)"
+
+# Build message with text and image content blocks
+message = Dict(
+    "role" => "user",
+    "content" => [
+        Dict("type" => "text", "text" => "Do you have Brunello di Montalcino?"),
+        Dict("type" => "image_url", "image_url" => Dict("url" => data_uri))
+    ]
+)
+promptAgent(agent, message)
+response = takeResponse(agent)
+```
+
+### Custom Hooks
+
+```julia
+# beforeToolCall — request user approval for destructive tools
+function my_before_tool_call(context::beforeToolCallContext, signal::abortSignal)::beforeToolCallResult
+    if context.toolCall.name == "deleteFile"
+        return beforeToolCallResult(true, "User must approve file deletion")
+    end
+    return beforeToolCallResult(false, "N/A")
+end
+
+# afterToolCall — mask sensitive data from results
+function my_after_tool_call(context::afterToolCallContext, signal::abortSignal)::Union{agentToolResult, Nothing}
+    if context.isError
+        return agentToolResult(
+            [textContent("The tool encountered an error. Please try again.")],
+            context.result.details, context.result.usage, context.result.terminate
+        )
+    end
+    return nothing
+end
+
+agent = yiemAgent(llmCall;
+    mcpServer=mcpServer,
+    beforeToolCall=my_before_tool_call,
+    afterToolCall=my_after_tool_call,
+    eventSink=println
+)
+```
+
+### Custom LLM Callable
+
+```julia
+function my_llm_call(messages_dict::Dict{String, Any})
+    # messages_dict contains "messages" key with OpenAI-format message array,
+    # plus optional "tools", "temperature", etc.
+
+    # Call your LLM provider (OpenAI, Anthropic, local model, etc.)
+    raw_response = call_my_llm_provider(messages_dict)
+
+    # Return a dict with these fields:
+    return Dict(
+        "message" => Dict("role" => "assistant", "content" => raw_response["content"]),
+        "finish_reason" => raw_response["finish_reason"],
+        "api" => "my_provider",
+        "provider" => "my_provider",
+        "model" => "my-model-name",
+        "usage" => llmUsage(100, 50)
+    )
+end
+```
+
+### Custom Context Preparation
+
+```julia
+function my_prepare_context(state::agentState, eventSink)::agentContext
+    sysPrompt = state.systemPrompt * "\nCurrent time: $(now())"
+    msgs = deepcopy(state.messages)
+
+    # Prune old messages to fit context window
+    max_messages = 20
+    if length(msgs) > max_messages
+        msgs = msgs[end-max_messages+1:end]
+    end
+
+    return agentContext(sysPrompt, msgs, state.tools)
+end
+
+agent = yiemAgent(llmCall; prepareContext=my_prepare_context, ...)
+```
+
+## MCP Server Integration
+
+YiemAgent uses JSON-RPC 2.0 for MCP communication. The `mcpServer` callable struct must implement `tools/list` and `tools/call` methods.
+
+### Protocol
+
+```julia
+# tools/list — returns tool definitions
+mcpServer("tools/list")
+# → Dict("jsonrpc"=>"2.0", "id"=>1, "result"=>Dict("tools"=>[...], "nextCursor"=>...))
+
+# tools/call — executes a tool
+mcpServer("tools/call", toolName, arguments)
+# → Dict("jsonrpc"=>"2.0", "id"=>2, "result"=>Dict("content"=>[...], "isError"=>...))
+
+# Protocol error responses include "error" instead of "result":
+Dict("jsonrpc"=>"2.0", "id"=>2, "error"=>Dict("code"=>-32602, "message"=>"..."))
+```
+
+### Example: NATS-based MCP Server Client
+
+```julia
+struct mcpServer
+    natsConn::NATS.Connection
+    topic::String
+    senderID::String
+    fileserver_url::String
+end
+
+# tools/list implementation
+function (c::mcpServer)(method::String)
+    payload = Dict("jsonrpc" => "2.0", "id" => 1, "method" => method, "params" => Dict{String, Any}())
+    payloads = [("payload", payload, "dictionary")]
+    _, msg_envelope = msghandler.smartpack(c.topic, payloads;
+        sender_id=c.senderID, msg_purpose="mcp_tools_list", fileserver_url=c.fileserver_url)
+    reply = NATS.request(c.natsConn, c.topic, msg_envelope, timeout=180)
+    incoming = msghandler.smartunpack(String(reply.payload))
+    return incoming["payloads"][1][2]
+end
+
+# tools/call implementation
+function (c::mcpServer)(method::String, toolName::String, arguments::Dict{String, Any})
+    payload = Dict("jsonrpc" => "2.0", "id" => 2, "method" => method,
+        "params" => Dict("name" => toolName, "arguments" => arguments))
+    payloads = [("payload", payload, "dictionary")]
+    _, msg_envelope = msghandler.smartpack(c.topic, payloads;
+        sender_id=c.senderID, msg_purpose="mcp_tool_call", fileserver_url=c.fileserver_url)
+    reply = NATS.request(c.natsConn, c.topic, msg_envelope, timeout=180)
+    incoming = msghandler.smartunpack(String(reply.payload))
+    return incoming["payloads"][1][2]
+end
+```
+
+## Tool Discovery
+
+Tools are discovered dynamically via the MCP server:
+
+1. `listTools` is the only pre-registered tool at agent creation
+2. When the LLM calls `listTools()`, tools are discovered from the MCP server and registered at runtime
+3. Supports pagination via `nextCursor` for large tool sets
+4. New tools become immediately available without restarting the agent
+
+## Hooks
+
+Hooks allow customization of the agent's behavior at key points in the execution pipeline.
+
+| Hook | Signature | Purpose |
+|------|-----------|---------|
+| `prepareContext` | `(state::agentState, eventSink) -> agentContext` | Transform messages/context before LLM call (filter tools, inject context, prune messages) |
+| `formatMsgForLLM` | `(ctx::agentContext, eventSink) -> Dict` | Convert agent context to LLM API message format |
+| `beforeToolCall` | `(context::beforeToolCallContext, signal::abortSignal) -> beforeToolCallResult` | Block/allow tool execution; request user approval |
+| `afterToolCall` | `(context::afterToolCallContext, signal::abortSignal) -> Union{agentToolResult, Nothing}` | Post-process tool results; mask sensitive data; set `terminate` flag |
+| `eventSink` | `(msg) -> nothing` | Callback for agent events/debug messages throughout the pipeline |
+
+## Agent Lifecycle
+
+1. **Creation** — `yiemAgent()` spawns a background task (`_agentLoop`) listening on `inputChannel` and `followUpChannel`
+2. **Input** — User messages enter via `promptAgent()` (immediate) or `followUp()` (queued while agent is busy)
+3. **Processing** — `_processMessage()` handles LLM calls, tool execution, and conversation history in a loop
+4. **Tool Execution Pipeline** — each tool call follows three phases:
+   - `prepareToolCall` — resolve tool, validate arguments, run `beforeToolCall` hook
+   - `executePreparedToolCall` — invoke `tool.execute()`
+   - `finalizeExecutedToolCall` — run `afterToolCall` hook, construct `toolResultMessage`
+5. **Termination** — tool `execute` functions can set `terminate=true` to stop the agent loop
+6. **Shutdown** — `stopAgent()` sends a `:shutdown` signal, drains channels, and closes the agent

-Tool that writes new Julia tool module files to disk.
-
-The agent can use this tool when it encounters a task that no existing tool
-can handle. Provide the tool's name, label, description, inputSchema, and
-execute logic as Julia code. The tool is written to `src/tools/<name>.jl`.
-
-After calling this tool, add the new file to `YiemAgent.jl` with an `include()`
-statement (after `include("toolRegistry.jl")`), then restart the agent.
-The new tool must be registered in `register_all_tools()` in `toolRegistry.jl`.
-
-# Example
-
-1. Agent calls writeTool with a spec for a "searchWine" tool
-2. writeTool generates src/tools/searchWine.jl
-3. Developer adds `include("tools/searchWine.jl")` to YiemAgent.jl
-4. Developer adds `registerTool(store, searchWineTool())` to register_all_tools()
-5. Restart agent — new tool is available
-
-# How It Works
-
-writeTool is a **file writer**, not a code generator. The LLM provides the
-tool logic as `executeCode`, and writeTool wraps it in Julia boilerplate:
-  - Converts `inputSchema` Dict into Julia `Dict{String,Any}(...)` string
-  - Indents `executeCode` with 4 spaces
-  - Wraps it inside `function executeTool(...)::agentToolResult ... end`
-  - Appends `writeToolTool()` returning an `agentTool` struct
-  - Writes the combined string to `src/tools/<name>.jl`
-
-# Important Notes
-
- The `executeCode` string is embedded literally into the generated tool.
-  Use `args["param_name"]` to access input parameters.
- The code string should be the function body (NOT wrapped in a function).
-  Lines will be indented with 4 spaces inside the execute function.
- Tool names must be valid Julia identifiers (lowercase letters, digits, underscores,
-  no leading digits or special characters).
