- Fix loop exit condition to check processor.message.finish instead of
result === "stop" (processor.process() returns "continue" on normal exit)
- Add system prompt instruction when json_schema mode is enabled to ensure
model calls the StructuredOutput tool
- Add integration tests for structured output functionality
- Fix test Session.messages call to use object parameter format
Add outputFormat option to session.prompt() for requesting structured JSON
output. When type is 'json_schema', injects a StructuredOutput tool that
validates model output against the provided schema.
- Add OutputFormat schema types (text, json_schema) to message-v2.ts
- Add structured_output field to AssistantMessage
- Add StructuredOutputError for validation failures
- Implement createStructuredOutputTool helper in prompt.ts
- Integrate structured output into agent loop with retry support
- Regenerate OpenAPI spec with new types
- Add unit tests for schema validation
Tests were failing in CI because the models.json cache file doesn't exist
and the data() macro fallback only works at build time, not runtime.
The preload now pre-fetches models.json and disables the background
refresh to prevent race conditions during test execution.
Custom headers configured for remote MCP servers were being silently
dropped when OAuth was enabled (the default). This test ensures headers
are always sent to MCP servers regardless of OAuth configuration.
Add comprehensive test suite for Provider module to ensure safe
refactoring of provider internals. Tests cover:
- Provider loading from env vars and config
- Provider filtering (disabled_providers, enabled_providers)
- Model whitelist/blacklist
- Model aliasing and custom providers
- getModel, getProvider, closest, defaultModel functions
Also adds Env module for instance-scoped environment variable access,
enabling isolated test environments without global state pollution.
