Struct StepTracker 

pub struct StepTracker { /* private fields */ }

Tracks required steps and executed tools in a workflow run.

Implementations

impl StepTracker

pub fn new(required_steps: Vec<String>) -> Self

Creates a new StepTracker with the given required steps.

pub fn record( &mut self, tool_name: &str, args: Option<&IndexMap<String, Value>>, )

Record that a tool was executed with the given arguments.

completed_steps is idempotent: recording the same tool twice does not add a duplicate. executed_tools accumulates all invocations.

pub fn is_satisfied(&self) -> bool

Returns true when all required steps have been recorded. An empty required_steps list is always satisfied.

pub fn pending(&self) -> Vec<String>

Returns required steps not yet completed, in declaration order.

pub fn check_prerequisites( &self, _tool_name: &str, args: &IndexMap<String, Value>, prerequisites: &[Prerequisite], ) -> PrerequisiteCheck

Check whether the prerequisites for a tool are satisfied given current args.

pub fn summary_hint(&self) -> String

Returns a human-readable summary of completed steps.

If no steps are completed, returns "[No steps completed yet]". Otherwise returns "[Steps completed: names]" in execution order.

pub fn completed_count(&self) -> usize

Number of completed steps (unique tool names).

pub fn required_steps(&self) -> &[String]

Returns a reference to the required steps list.
