feat(harnesses): Pass run context to agent factories#55
Merged
Conversation
Let first-party harness agent factories receive the eval input and harness context before instrumentation or execution. This keeps input-dependent agents on the native replay path without side-channel setup. Fixes GH-54 Co-Authored-By: OpenAI Codex <codex@openai.com>

Agent factories in the first-party harnesses now receive the eval input and harness context before the harness instruments tools or executes the run. This lets per-run agents derive instructions, tool closures, metadata, and artifacts without AsyncLocalStorage or other side-channel setup.
Contextual Factories
OpenAI Agents and Pi AI create their agents before native tool instrumentation, so createAgent now receives { input, context } in both harnesses. AI SDK agent factories receive the same shape for consistency and lower boilerplate.
Docs And Policy
Update harness READMEs, skill references, and the API design policy so future harness surfaces prefer one contextual per-run factory object.
Validated with pnpm exec biome lint, pnpm exec vitest run for the three harness test files, pnpm run typecheck, and pnpm run build.
Fixes #54
