Metadata

  • Commit message: feat: implement additional LLM backends and provider integrations
  • Branch name: feat/additional-llm-backends-provider-integrations

Background and Context

v3.6.0 (M7: Advanced Concepts & Deferred Features) includes additional LLM backends and provider integrations beyond the core providers (OpenAI, Anthropic, Google). This Epic tracks the implementation of additional provider support including OpenRouter, Azure OpenAI, and other LangChain-compatible providers.

The ProviderRegistry.create_llm method currently only supports a limited set of providers. As the system matures, users need access to additional providers for cost optimization, capability access, and regional compliance. OpenRouter in particular provides access to many models through a single API endpoint.

Current Behavior

ProviderRegistry.create_llm raises ValueError: Unsupported provider type for providers not in the initial implementation (e.g., OpenRouter). Users cannot use alternative LLM providers without modifying source code.

Expected Behavior

All providers defined in ProviderType enum are supported by ProviderRegistry.create_llm. Users can configure any supported provider via agents config set provider.type <name>. Provider-specific settings (API keys, base URLs, model names) are configurable.

Acceptance Criteria

  • OpenRouter provider support added to ProviderRegistry.create_llm
  • Azure OpenAI provider support verified/added
  • All ProviderType enum values have corresponding create_llm implementations
  • Provider configuration documented in docs/reference/providers.md
  • All child issues are closed and merged
  • Test coverage >= 97% for provider registry

Subtasks

  • Add OpenRouter support to ProviderRegistry.create_llm (#8350)
  • Audit all ProviderType enum values for missing implementations
  • Add missing provider implementations
  • Write unit tests for each new provider
  • Update provider documentation

Parent Legendary

Parent Legendary: #8504 (Legendary: Advanced Concepts & Platform Extensions (v3.6.0))

Definition of Done

Epic complete when all ProviderType enum values are supported by ProviderRegistry.create_llm, all child issues are closed, and provider documentation is updated.

Triage Decision: Verified — Should Have

Verified by: Project Owner Supervisor [AUTO-OWNR-2]
MoSCoW: Should Have (confirmed)
Priority: High (confirmed)
Milestone: v3.6.0 (M7: Advanced Concepts & Deferred Features)

This Epic is correctly scoped to v3.6.0. Additional LLM provider integrations are a Should Have for production quality but not a Must Have for core milestone completion. The Epic is well-structured with clear acceptance criteria and links to child issue #8350.

Rationale: Provider extensibility is important for user adoption but does not block core plan execution, decision recording, or autonomy hardening features (v3.2.0–v3.5.0).
