The current model only supports User/Assistant/System and appends tool results as User messages, which breaks OpenAI compatibility. + +**Step 1: Write tests for new message types** + +Create `tests/message_test.rs`: +```rust +use rustagent::llm::{Message, Role}; + +#[test] +fn test_tool_message_creation() { + let msg = Message::tool_result("call_123", "File contents here"); + assert_eq!(msg.role, Role::Tool); + assert_eq!(msg.tool_call_id, Some("call_123".to_string())); + assert_eq!(msg.content, "File contents here"); +} + +#[test] +fn test_user_message_has_no_tool_call_id() { + let msg = Message::user("Hello"); + assert_eq!(msg.role, Role::User); + assert!(msg.tool_call_id.is_none()); +} +``` + +**Step 2: Run test to verify it fails** + +Run: `cargo test test_tool_message` +Expected: FAIL - no `tool_result` method + +**Step 3: Extend Message struct and Role enum** + +In `src/llm/mod.rs`: +```rust +#[derive(Debug, Clone, Serialize, Deserialize, PartialEq)] +#[serde(rename_all = "lowercase")] +pub enum Role { + User, + Assistant, + System, + Tool, +} + +#[derive(Debug, Clone, Serialize, Deserialize)] +pub struct Message { + pub role: Role, + pub content: String, + #[serde(skip_serializing_if = "Option::is_none")] + pub tool_call_id: Option, +} + +impl Message { + pub fn user(content: impl Into) -> Self { + Self { + role: Role::User, + content: content.into(), + tool_call_id: None, + } + } + + pub fn assistant(content: impl Into) -> Self { + Self { + role: Role::Assistant, + content: content.into(), + tool_call_id: None, + } + } + + pub fn system(content: impl Into) -> Self { + Self { + role: Role::System, + content: content.into(), + tool_call_id: None, + } + } + + pub fn tool_result(tool_call_id: impl Into, content: impl Into) -> Self { + Self { + role: Role::Tool, + content: content.into(), + tool_call_id: Some(tool_call_id.into()), + } + } +} +``` + +**Step 4: Update AnthropicClient to handle tool results** + +In `src/llm/anthropic.rs`, update message formatting to handle Role::Tool (Anthropic uses a different format - tool results go in the user turn with tool_result blocks, but for now we can skip Tool messages in the Anthropic format since we'll refactor the loop). + +**Step 5: Update ralph and planning loops to use Message constructors** + +Replace manual Message struct creation with the new constructors.
