 Julia framework for building agents with tool use and MCP (Model Context Protocol) support.

-## Getting Started
+## Quick Start

-1. Install dependencies: `]add JSON, DataStructures, UUIDs, Dates, NATS, DataFrames`
-2. Create a callable `mcpServer` struct that communicates with an MCP server via NATS
-3. Create a `yiemAgent` with an LLM callable and MCP server:
 ```julia
-   agent = YiemAgent.yiemAgent(llmCall; mcpServer=mcpServer, eventSink=yourSink)
-   ```
-4. Call `promptAgent(agent, message)` then `takeResponse(agent)`

-## MCP Protocol
+## Agent API

-YiemAgent uses JSON-RPC 2.0 for MCP communication. The `mcpServer` callable struct must implement:
+| Function | Description |
+|----------|-------------|
+| `promptAgent(agent, text)` | Send plain text to the agent's input channel |
+| `promptAgent(agent, msg)` | Send a structured message (OpenAI format dict) to the input channel |
+| `takeResponse(agent)` | Block and take the agent's response from output channel |
+| `followUp(agent, text)` | Send plain text follow-up while agent is still processing |
+| `followUp(agent, msg)` | Send a structured follow-up (OpenAI format dict) while agent is processing |
+| `stopAgent(agent)` | Gracefully stop the agent and close channels |
+
+## Creating a yiemAgent
+
+```julia
+yiemAgent(llmCall;
+    systemPrompt::String = "You are a helpful assistant.",
+    model = nothing,
+    messages::Vector{agentMessage} = agentMessage[],
+    prepareContext::Function = prepareContext,
+    formatMsgForLLM::Function = formatMsgForLLM,
+    beforeToolCall::Function = beforeToolCall,
+    afterToolCall::Function = afterToolCall,
+    sessionId::Union{String, Nothing} = nothing,
+    maxRetryDelayMs::Union{Int64, Nothing} = nothing,
+    parallelToolExecute::Bool = false,
+    eventSink::Function = eventSink,
+    mcpServer = nothing
+)
+```
+
+| Parameter | Description |
+|-----------|-------------|
+| `llmCall` | **(required)** Function that receives formatted messages and returns an LLM response |
+| `systemPrompt` | System prompt for the agent |
+| `model` | LLM model configuration (`llmModel` struct) |
+| `messages` | Initial conversation messages |
+| `prepareContext` | Hook to transform messages/context before each LLM call |
+| `formatMsgForLLM` | Hook to convert agent context to LLM API format |
+| `beforeToolCall` | Hook to block/allow tool execution |
+| `afterToolCall` | Hook to post-process tool results |
+| `sessionId` | Optional session identifier for MCP server |
+| `maxRetryDelayMs` | Maximum retry delay in milliseconds |
+| `parallelToolExecute` | Run multiple tool calls in parallel |
+| `eventSink` | Callback for agent events/debug messages |
+| `mcpServer` | Callable struct for MCP server communication |
+
+## 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"=>...))
+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"=>...))
-```
+mcpServer("tools/call", toolName, arguments)
+# → Dict("jsonrpc"=>"2.0", "id"=>2, "result"=>Dict("content"=>[...], "isError"=>...))

-Protocol error responses include `"error"` instead of `"result"`:
-```julia
+# Protocol error responses include "error" instead of "result":
 Dict("jsonrpc"=>"2.0", "id"=>2, "error"=>Dict("code"=>-32602, "message"=>"..."))
 ```

-### Implementing the MCP Server Client

-You must provide a callable struct that communicates with your MCP server. Example using NATS:

 ## Tool Discovery

-Tools are discovered dynamically via MCP server:
+Tools are discovered dynamically via the MCP server:

-1. `listTool` is the only pre-registered tool
+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
-
-## Agent API
-
-| Function | Description |
-|----------|-------------|
-| `promptAgent(agent, msg)` | Send a message to the agent's input channel |
-| `takeResponse(agent)` | Block and take the agent's response from output channel |
-| `followUp(agent, msg)` | Send a follow-up message while agent is still processing |
-| `stopAgent(agent)` | Gracefully stop the agent and close channels |
-
-## Agent Lifecycle
-
-1. `yiemAgent()` spawns a background task (`_agentLoop`) listening on `inputChannel` and `followUpChannel`
-2. User messages enter via `promptAgent()` or `followUp()`
-3. `_processMessage()` handles LLM calls, tool execution, and conversation history
-4. Tool execution follows three phases: `prepareToolCall` → `executePreparedToolCall` → `finalizeExecutedToolCall`
-5. `beforeToolCall`/`afterToolCall` hooks allow pre/post-processing of tool calls
-6. Tool `execute` functions can set `terminate=true` to stop the agent loop
+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, sink, llmCall) -> ctx` | Transform messages/context before LLM call |
-| `formatMsgForLLM` | `(ctx, sink) -> dict` | Convert agent context to LLM API format |
-| `beforeToolCall` | `(context, signal) -> result` | Block/allow tool execution |
-| `afterToolCall` | `(context, signal) -> result` | Post-process tool results |
-| `eventSink` | `(msg) -> nothing` | Callback for agent events/debug messages |
+| `prepareContext` | `(state::agentState, eventSink) -> agentContext` | Transform messages/context before LLM call (filter tools, inject context, prune messages) |

+## 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
+
