Struct CodexProvider 

pub struct CodexProvider;

Codex provider. Argv mirrors codex.py (codex exec --json ... / codex exec resume <id> --json ...); the stream parser is pinned to the codex 0.130 JSONL vocabulary captured in cli/tests/agents/fixtures/codex-jsonl-sample.jsonl.

Trait Implementations

impl Provider for CodexProvider

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

Stable provider identifier ("claude" / "codex" / "gemini").

fn create_argv(&self, ctx: &CreateContext) -> Vec<String>

Argv for a fresh session.

fn resume_argv(&self, ctx: &ResumeContext) -> Vec<String>

Argv for continuing a session.

fn create_interactive_argv(&self, ctx: &CreateContext) -> Option<Vec<String>>

Argv for a fresh interactive session (host_mode = interactive, the fno agents host verb). Default None: claude has no abi-hosted interactive form (it drives via its own --bg surface), so host rejects provider=claude before reaching here. codex/gemini override. Returning None keeps the “not interactive-hostable” fact in the type system rather than as a panicking no-op (the same discipline as Provider::as_pty).

fn resume_interactive_argv(&self, ctx: &ResumeContext) -> Option<Vec<String>>

Argv for resuming an existing session interactively (the fno agents promote --from <uuid> verb). ctx.session_id is the resume target UUID. Default None (claude); codex/gemini override.

fn parse_stream_event(&self, chunk: &str) -> ParsedEvent

Parse one unit of provider stream output into the sealed ParsedEvent vocabulary. The unit is provider-shaped: codex is fed one JSONL line at a time; gemini is fed its complete JSON blob (it emits a single document at EOF, so per-line feeding yields ParsedEvent::Unknown until the daemon has the whole blob). Unrecognized input becomes ParsedEvent::Unknown rather than an error, so a provider version bump degrades gracefully.

fn reachability( &self, entry: &AgentEntry, _timeout: Duration, ) -> Result<bool, ReachabilityProbeError>

Probe whether entry’s session is still reachable. Returns Ok(true) / Ok(false) for a definitive answer, Err(ReachabilityProbeError) when the probe is inconclusive. timeout bounds any I/O the probe performs.

fn as_pty(&self) -> Option<&dyn ProviderWithPty>

Downcast to the PTY-managed extension, or None for shellout providers (claude). The daemon’s spawn handler matches on this to route between the portable-pty path and the shellout path.

impl ProviderWithPty for CodexProvider

fn readiness_detector(&self) -> Box<dyn ReadinessDetector>

Per-CLI readiness signal over the terminal grid.

fn envelope(&self) -> Box<dyn Envelope>

Structural anti-injection envelope for input on the PTY stdin path.

fn default_restart_policy(&self) -> RestartPolicy

Provider-recommended restart policy. The daemon’s enforcer still imposes the hard ceiling (crate::supervisor::HARD_FAILURE_CEILING, LD36) regardless of what a provider returns.
