Struct PiAgent 

pub struct PiAgent;

Legacy AgentAdapter face for Pi (D-11 removal point). Delegates to PiDriver.

Trait Implementations

impl AgentAdapter for PiAgent

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

Human-readable adapter name.

fn exec_command( &self, phase: PhaseId, prompt: &str, extra_writable_roots: &[PathBuf], ) -> (&'static str, Vec<String>)

Build the command and arguments to launch this agent headless with the given prompt for phase. Returns (program, args).

fn completion_signal_detected(&self, _output: &str) -> bool

Detect an agent-specific completion signal in captured output.

fn preflight(&self, state: &State) -> Result<(), String>

Adapter-specific pre-launch readiness check (D-13/D-14 adapter hook, Phase 17c). The default is a no-op — most adapters have nothing extra to check, mirroring Self::extra_env’s empty-default shape. The Err variant is a human-readable failure reason that flows into the preflight gate’s context (run_preflight in devflow-cli/src/main.rs). This is the trait surface Phase 18’s Hermes adapter implements to enforce a non-empty reviewer/receiver set — no built-in adapter (Claude/Codex/OpenCode) overrides it in Phase 17 because no reviewer-set storage exists yet in state.rs/config.rs (review consensus #6).

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

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

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

Extra environment variables for the agent process tree. Codex uses this to disable commit/tag signing inside its sandbox: the operator’s signing agent (ssh-agent/gpg-agent) is unreachable there, so signed commits fail headless with a passphrase error (13-06 dogfood finding — same rationale as the unsigned VersionBump tags). GIT_CONFIG_* env scoping keeps the override out of every repo/global config.
