Struct Harness 

pub struct Harness { /* private fields */ }

The agent harness an eval runs against: a validated handle to an entry in the descriptor registry. Constructible only through registry resolution, so a held Harness always names a registered harness and adapter lookup never fails. The registry-dependent behavior lives next to the registry in crate::adapters::harness: Harness::resolve (the string-to-handle gateway, resolving --harness after parsing), Harness::known (every registered harness), Default (the registry’s default harness), and Deserialize (resolves artifact values, rejecting unknown names).

Implementations

impl Harness

pub fn resolve(name: &str) -> Result<Harness, UnknownHarnessError>

Resolve a kebab-case identifier against the descriptor registry — the only way to obtain a Harness, so every held handle is valid.

pub fn known() -> impl Iterator<Item = Harness>

Every registered harness, in registry (embedded descriptor) order — for code that must sweep all of them (e.g. guard teardown scans each harness’s skills dir for a marker).

impl Harness

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

The kebab-case identifier (claude-code, codex, opencode, …) — the --harness flag value and the harness value in artifacts.
