Test Reasoning Serialization
Validates that ReasoningConfig fields are correctly serialized into provider-specific JSON
for OpenRouter, Anthropic, GitHub Copilot, and Codex.
Quick Start
Run all tests with the bundled script:
./scripts/test-reasoning.sh
The script builds forge in debug mode, runs each provider/model combination, captures the
outgoing HTTP request body via FORGE_DEBUG_REQUESTS, and asserts the correct JSON fields.
Running a Single Test Manually
FORGE_DEBUG_REQUESTS="forge.request.json" \
FORGE_SESSION__PROVIDER_ID=<provider_id> \
FORGE_SESSION__MODEL_ID=<model_id> \
FORGE_REASONING__EFFORT=<effort> \
target/debug/forge -p "Hello!"
Then inspect .forge/forge.request.json for the expected fields.

Tests for unconfigured providers are skipped automatically. Invalid-effort tests run regardless of credentials — the rejection happens at config parse time before any provider interaction.
