Struct PiDriver 

pub struct PiDriver;

The modular driver for Pi (37-03): print-mode -p launch, pi auth check health, and the de-Claude-ified workflow-reference prompt. NO JSON unwrapper or monitor/CloseRule integration here — that is 37.1/38 (CONTEXT D-04).

Trait Implementations

impl AgentDriver for PiDriver

fn workflow_root(&self) -> String

Pi installs its GSD workflows under ~/.pi/agent/gsd-core/workflows/, NOT the Codex install the default points at (code-review finding #5).

fn capabilities(&self) -> DriverCapabilities

Pi declares subagent-dispatch capability when a subagent extension is installed in the user profile (see [pi_subagent_dispatch_available]).

fn name(&self) -> &'static str

Human-readable driver name.

fn render_prompt(&self, intent: &StageIntent) -> String

Render the stage prompt for this agent from a crate::prompt::StageIntent.

fn build_command( &self, _phase: PhaseId, prompt: &str, _extra_writable_roots: &[PathBuf], ) -> (&'static str, Vec<String>)

Build the command and arguments to launch this agent headless.

fn health(&self, _state: &State) -> Result<(), String>

Driver-specific pre-launch health check.

fn parse_completion(&self, _output: &str) -> Option<AgentResult>

Parse this agent’s completion signal out of captured output; None when the transport is process-exit (no event stream to scan).

fn environment(&self) -> Vec<(String, String)>

Extra environment variables for the agent process tree.

fn sandbox_requirements(&self) -> SandboxRequirements

Sandbox requirements for this agent’s launch.

fn discover(&self) -> Result<(), String>

Discover capabilities from the installed CLI (e.g. codex features list).

fn test_contract(&self) -> Vec<ContractResult>

The conformance suite every driver must pass (37-04).

fn interactivity_mode(&self, _stage: Stage) -> InteractivityMode

The interactivity requirement for running stage headless.

fn health_classification(&self, state: &State) -> DriverHealth

Classify this driver’s health (the pass/fail AgentDriver::health mapped onto the richer DriverHealth).
