Struct TodoTool 

pub struct TodoTool { /* private fields */ }

Holds the list for the lifetime of the agent.

Implementations

impl TodoTool

pub fn new() -> Self

pub fn items(&self) -> Vec<TodoItem>

Current list, for a UI that wants to render progress live.

Trait Implementations

impl Default for TodoTool

fn default() -> TodoTool

Returns the “default value” for a type.

impl Tool for TodoTool

fn carried_state(&self) -> Option<CarriedState>

The list survives a compaction verbatim.

The model re-reads its plan every turn through the echo in the last todo result — which is a message, and therefore exactly the kind of thing a compaction summarises away. That made this tool’s whole mechanism quietly conditional on the transcript never getting long, which is the one situation the list matters most in: the measured failure of summarisation is that it keeps what is true and drops how far you got, and this list is nothing but how far you got.

Rendered rather than summarised, because the tool holds the exact current answer and a summariser would only be a lossy path to a worse copy of it.

fn name(&self) -> &str

fn description(&self) -> &str

fn input_schema(&self) -> Value

fn read_only(&self) -> bool

Read-only tools skip the approval gate and are safe to run in parallel.

fn call<'life0, 'life1, 'async_trait>( &'life0 self, input: Value, _ctx: &'life1 ToolCtx, ) -> Pin<Box<dyn Future<Output = Result<ToolOutput>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

fn capabilities(&self) -> Capabilities

Declared risk surface. The default is the conservative one for a tool nobody has classified: assume it does nothing special.

fn denial_remedy(&self) -> Option<String>

How the operator could make a call like the one just refused safe — one sentence appended to a trifecta denial, or None when nothing short of policy would change the answer.

fn fixed_workspace(&self) -> Option<PathBuf>

The root this tool’s relative paths actually resolve against, when the tool was constructed over a fixed directory rather than following the per-run ToolCtx workspace.

fn narrows_surface_to(&self) -> Option<Vec<String>>

Tool names this tool is currently restricting the surface to, if it is restricting it at all.

fn forget_conversation_state(&self)

Drop state that belonged to the conversation that just ended.

fn spec(&self) -> ToolSpec
