OptionalagentResolve the prompt from an agent's active prompt binding instead of naming it.
OptionalagentSame, by agent NAME. The corpus states its agent by name — golden files stay readable and diffable, and the suite generator runs offline with no database to resolve a GUID against.
OptionalconfigurationOptionaleffortPer-cell reasoning effort. Numeric 1-100 is MJ's cross-provider scale; a provider-named
level (OpenAI's 'xhigh' / 'none') is passed through verbatim for the levels that scale
cannot express. Part of the cell identity, so two effort levels are two cells, not noise
pooled into one.
OptionalmaxOptionalmodelPer-cell model pinning — this is the matrix axis (§3.3).
OptionalnativeControl-flow arm for a native cell. 'implicit' keeps the control tools the composer
declared (the model's catalog must also say NativeControlFlow: 'implicit' for the runner to
send them); 'envelope' (default) strips them here so the cell measures the hybrid on a
model whose catalog has been switched to implicit for the gate run.
OptionalnativeNative-tool-results arm: send tool-form history (assistant toolCalls + tool turns) as native tool turns.
Otherwise the driver renders that history as the corpus's [Action Result] … prose, which is
what the loop shows models that do not return results natively.
OptionalpromptThe prompt to run. Exactly one of promptId / agentId is required.
OptionalscoringOptionalsystemReplaces the composed system prompt wholesale. Used by the trimmed-prompt variant cells.
OptionaltoolWhich wire encoding this cell observes.
The composer attaches the agent's Actions as native tool declarations unconditionally,
because that is what BaseAgent does and the whole point of composing through it is to send
what production sends. A cell measuring the ENVELOPE therefore has to take them back off:
toolsProvided is one of the three terms in the runner's gate, so withholding declarations
is exactly how a real envelope-mode call differs from a native one. Nothing else about the
request changes, which is what keeps the two arms comparable.
Defaults to 'envelope', so a record written before this axis existed —
keeps measuring the baseline it was generated to measure.
Optionaltooltool_choice for a native cell. Omitted accepts the agent's own default ('auto').
