Description

What variant of Codex are you using?

Codex with our Eclipse IDE plugin (codexide.org)

What feature would you like to see?

TurnStartParams and TurnSteerParams define AdditionalContextEntry / AdditionalContextKind (untrusted | application), but no property references them: these are dead definitions in the schema.
As a result, the plugin serializes the active editor, cursor, selection, and open tabs as a text block pasted into the prompt.
This is token-expensive on every turn, untyped, impossible to refresh mid-turn, and the model may mistake it for the instruction.
Our request : expose additionalContext: [{kind, value}] on turn/start and turn/steer (the type already exists server-side, it's nearly free).

Research direction

Start by locating TurnStartParams and TurnSteerParams and the existing AdditionalContextEntry and AdditionalContextKind definitions in the schema. Trace how these parameters are serialized, then expose the requested additionalContext entries on both turn/start and turn/steer and verify that the resulting schema and request payloads include kind and value.
