Struct HermesDriver 

pub struct HermesDriver;

The modular driver for Hermes (Phase 42): headless -z oneshot launch, HERMES_ACCEPT_HOOKS=1 environment, standard claude-style prompt rendering, and dynamic delegation subagent dispatch probing.

Trait Implementations

impl AgentDriver for HermesDriver

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 capabilities(&self) -> DriverCapabilities

Capabilities this driver declares (as-needed; default empty).

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

Extra environment variables for the agent process tree.

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 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 workflow_root(&self) -> String

The directory holding this agent’s GSD workflow files, used by the workflow-reference renderer. Defaults to the Codex install; a driver with a different install (e.g. Pi) overrides it.

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

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