Implement external service mode (HTTP proxy on port 3456) +- Implement library integration mode (in-process routing) +- Merge configuration (proxy TOML + Role extra fields) +- Unify session management +- Add routing transparency (logs, API responses) +- Maintain backward compatibility with static model selection +- Comprehensive testing (reuse proxy's 186 tests + integration tests) + +**Out of Scope:** +- Multi-modal routing beyond image scenario (proxy handles images) +- Reinforcement learning routing +- Custom plugin system (proxy already extensible) +- Web UI for routing configuration

Integration vs External Service** | In-process routing eliminates network overhead, single deployment unit, unified architecture | External service (adds 50ms+ network hop, distributed complexity) | +| **Reuse Existing Proxy** | Proven code (186 tests), production-ready, Terraphim-specific (RoleGraph), eliminates development risk | Build from scratch (months of work), integrate external LLMRouter (Python bridge overhead) | +| **Adapter Pattern** | Clean separation, maintains existing `LlmClient` interface, easy to disable/enable | Direct modification of `LlmClient` implementations (breaking changes) | +| **Backward Compatibility** | Existing roles with static `llm_model` still work, gradual migration | Breaking change (all roles require config update) | +| **Phase 1+2 Delivery** | Prove value incrementally, reduce risk, clear rollback path | Full library integration upfront (big bang, higher risk) | +| **Reuse Proxy Tests** | 186 tests already pass, no rewriting, focus on integration | Rewrite all tests (massive effort, risk of bugs) | +| **Feature Flag Control** | Users can disable routing if issues, no breaking changes | Force routing on all roles (risk, no fallback) | + +##

Terraphim AI currently uses static model selection through role-based configuration. Integrating LLMRouter's intelligent routing capabilities could significantly improve cost efficiency, response quality, and user experience by automatically selecting the best model for each query. + +## Problem Statement + +### Description +Terraphim AI currently uses static LLM model selection configured per role. Users manually select a single model (e.g., "gpt-3.5-turbo" or "llama3.1") that is used for all queries regardless of query complexity, cost considerations, or performance requirements. This approach has several limitations: + +1. **Cost Inefficiency**: Simple queries (e.g., basic summarization) use expensive models when cheaper models would suffice +2. **Quality Trade-offs**: Complex queries may use underpowered models when more capable models are available +3. **Manual Management**: Users must manually select and switch models based on perceived query complexity +4. **No Adaptive Learning**: The system doesn't learn from usage patterns or optimize routing over time +5. **Wasted Resources**: Over-provisioning on simple tasks and under-provisioning on complex tasks + +### Impact +**Who is affected:** +- **End Users**: Experience higher costs than necessary, potentially suboptimal response quality +- **Administrators**: Must manually configure and update model selections for different use cases +- **System Performance**: Suboptimal resource utilization leads to higher operational costs + +**Business Impact:** +- Increased API costs from using expensive models for simple queries +- Potential degradation in user satisfaction from mismatched model capabilities +- Loss of competitive advantage compared to systems with intelligent routing + +### Success Criteria +1. **Cost Reduction**: Reduce LLM API costs by 20-40% through intelligent model selection +2. **Quality Maintenance**: Maintain or improve response quality compared to static routing +3. **User Transparency**: Users can see which model was selected and why +4. **Learning Capability**: System improves routing decisions based on usage patterns +5. **Flexibility**: Support multiple routing strategies (cost-first, quality-first, balanced) + +## Current State Analysis + +### Existing Implementation + +**LLM Client Architecture:** + +``` +┌─────────────────────────────────────────┐ +│ terraphim_service::llm module │ +├─────────────────────────────────────────┤ +│ LlmClient (trait) │ +│ - summarize() │ +│ - chat_completion() │ +│ - list_models() │ +└─────────────────────────────────────────┘ + ▲ ▲ + │ │ + │ │ + │ │ +┌─────────────────┐ ┌──────────────────┐ +│ OpenRouterClient │ │ OllamaClient │ +│ - openrouter │ │ - ollama │ +└─────────────────┘ └──────────────────┘ + ▲ + │ +┌─────────────────────────────────────────┐ +│ LlmProxyClient │ +│ - Unified proxy configuration │ +│ - Auto-detect providers │ +│ - Connectivity testing │ +└─────────────────────────────────────────┘ + ▲ + │ +┌─────────────────────────────────────────┐ +│ GenAiLlmClient │ +│ - Multi-provider support │ +│ - Ollama, OpenAI, Anthropic, │ +│ OpenRouter │ +└─────────────────────────────────────────┘ +``` + +**Key Components:** + +| Component | Location | Purpose | +|-----------|----------|---------| +| `LlmClient` trait | `crates/terraphim_service/src/llm.rs:20` | Abstract interface for LLM operations | +| `OpenRouterClient` | `crates/terraphim_service/src/llm.rs:169` | Commercial LLM provider | +| `OllamaClient` | `crates/terraphim_service/src/llm.rs:227` | Local LLM provider | +| `LlmProxyClient` | `crates/terraphim_service/src/llm_proxy.rs:86` | Unified proxy with auto-configuration | +| `GenAiLlmClient` | `crates/terraphim_multi_agent/src/genai_llm_client.rs:16` | Multi-provider client using rust-genai | +| `Role` struct | `crates/terraphim_config/src/lib.rs:178` | User configuration with LLM settings | + +**Role-based Configuration:** + +```rust +pub struct Role { + pub llm_enabled: bool, // Enable LLM features + pub llm_api_key: Option, // API key + pub llm_model: Option, // Static model selection + pub llm_auto_summarize: bool, // Auto-summarize results + // ... other fields +} +``` + +**Provider Support:** +- **OpenRouter**: Commercial models via API (GPT, Claude, etc.) +- **Ollama**: Local models (Llama, Gemma, etc.) +- **Anthropic**: Direct API with optional z.ai proxy +- **OpenAI**: Direct API support + +**Current Routing Logic:** +```rust +// Static model selection from role configuration +pub fn build_llm_from_role(role: &Role) -> Option> { + // Check provider preference + if let Some(provider) = get_string_extra(&role.extra, "llm_provider") { + match provider.as_str() { + "ollama" => build_ollama_from_role(role), + "openrouter" => build_openrouter_from_role(role), + // ... more providers + } + } + // Fallback logic +} +``` + +### Data Flow + +``` +User Query + ↓ +Role Configuration (static model selection) + ↓ +LlmClient Builder (build_llm_from_role) + ↓ +Provider Selection (OpenRouter/Ollama/etc.) + ↓ +LLM API Call + ↓ +Response +``` + +**Current Limitations:** +1.

-1. **Phase 1**: External service mode (minimal changes, prove value) -2. **Phase 2**: Library integration (in-process routing, full benefits) -3. **Phase 3**: Advanced features (cost optimization, performance metrics) - -This approach provides: -- ✅ **Immediate value** with minimal risk -- ✅ **Zero network overhead** (in-process routing) -- ✅ **Proven code** (186 tests, production-ready) -- ✅ **Terraphim-specific** (RoleGraph integration) -- ✅ **Consistent architecture** (native Rust) - -### Scope - -**In Scope:** -- Add `terraphim_llm_proxy` as workspace dependency -- Create adapter layer between `LlmClient` trait and proxy routing -- Implement external service mode (HTTP proxy on port 3456) -- Implement library integration mode (in-process routing) -- Merge configuration (proxy TOML + Role extra fields) -- Unify session management -- Add routing transparency (logs, API responses) -- Maintain backward compatibility with static model selection -- Comprehensive testing (reuse proxy's 186 tests + integration tests) - -**Out of Scope:** -- Multi-modal routing beyond image scenario (proxy handles images) -- Reinforcement learning routing -- Custom plugin system (proxy already extensible) -- Web UI for routing configuration (use existing TOML) -- Port conflicts resolution (proxy runs on 3456, external mode) -

-### Key Decisions from Interview - -#### Concurrency & Race Conditions - -**Q1.1: Multiple users, same pattern** → **Option A: Deterministic routing** -- Both users route to same provider/model for same pattern -- Easier debugging, consistent behavior -- Tradeoff: No load balancing across multiple good options - -**Q1.2: User cancels during routing** → **Option A: Continue routing and cache result** -- Wastes computation on canceled request -- Populates cache for future similar requests -- Tradeoff: Resource waste for better cache hit rate - -**Q1.3: Rapid-fire requests from same session** → **Option A: Cache routing decision with TTL** -- Cache routing decision per session -- TTL: ~5 minutes (configurable) -- Tradeoff: Doesn't adapt to changing conditions within cache window - -#### Failure Modes & Recovery - -**Q2.1: Provider returns 429 rate limit** → **Option B: Fallback to Phase 2** -- Graceful degradation through routing phases -- Tries next routing phase instead of immediate failure -- Tradeoff: Slower fallback but user gets response - -**Q2.2: Proxy routing logic panics** → **Option B: Fallback to static LLM client** -- Adapter layer catches panic, uses existing static routing -- Maximum resilience, existing behavior maintained -- Tradeoff: No routing during that request (acceptable fallback) - -**Q2.3: Optimization phases enabled but no data** → **Option B: Use default values** -- Use average pricing, 50th percentile performance -- Proactively enable phases with reasonable defaults -- Tradeoff: May not be optimal initially, but works - -#### Edge Cases & Boundaries - -**Q3.1: Explicit provider not configured** → **Option A: Return 400 Bad Request** -- Clear error message with configured providers list -- Fail fast, user knows exactly what to fix -- Tradeoff: No fallback, but explicit failure - -**Q3.2: Multiple equal-scoring matches** → **Option B: Select higher priority** -- Use priority metadata from taxonomy files -- Deterministic tie-breaking -- Tradeoff: Requires priority configuration in patterns - -**Q3.3: Request exceeds all context limits** → **Option B: Return error, ask to reduce** -- Clear error message about size limits -- User action required to proceed -- Tradeoff: Poor UX but prevents silent truncation/failure - -#### User Mental Models - -**Q4.1: Unexpected model selected** → **Option C: API metadata with routing reason** -- Return in response: `{"model": "deepseek-chat", "routing_reason": "Pattern matched: low_cost_routing (priority: 50)"}` -- API-level transparency, developers can expose in UI if desired -- Tradeoff: More response data, but full transparency - -**Q4.2: User feedback on routing quality** → **Option C: Adjust routing weights + User-editable KG** -- Leverage Terraphim Knowledge Graph for routing patterns -- Users can edit/create taxonomy files (Terraphim infrastructure) -- Global routing adjustments based on user feedback -- Tradeoff: Learning complexity, but powerful customization - -**Q4.3: Terminology** → **Options A + D: Dual terminology** -- User-facing/marketing: "Intelligent Routing" -- Technical/developer: "Dynamic Routing" -- Clear audience segmentation -- Tradeoff: Two terms to maintain, but clearer communication - -#### Scale & Performance - -**Q5.1: Acceptable routing overhead** → **Option D: <10ms maximum** -- Very lenient target -- Routing overhead negligible compared to 500-5000ms LLM latency -- Tradeoff: May not require heavy optimization - -**Q5.2: Pattern database grows to 2000+** → **Options C + A: Hybrid approach** -- Implement pattern hierarchy using Terraphim KG -- Keep Aho-Corasick for active set (categorization) -- Criterion benchmarks: <1% difference between 200 and 2000 patterns -- Leverage `terraphim-automata` crate -- Tradeoff: More complex categorization, but proven scalability - -**Q5.3: Request batching** → **Option C: No batching** -- Always process immediately -- No queuing or batching complexity -- Tradeoff: Missed cost optimization opportunity, but simpler - -#### Security & Privacy - -**Q6.1: Routing decision logging** → **Option C: Log full routing decision (security auditing)** -- Log provider, model, reasoning, phase used -- Full observability for security team -- Tradeoff: More logs, but necessary for auditing - -**Q6.2: User lacks API keys for routed provider** → **Option B: Check credentials, skip routing decision** -- Validate user has keys before attempting routing -- Try next routing phase instead of failing -- Tradeoff: More validation overhead, but graceful fallback - -**Q6.3: External service mode auth** → **Option B with fallback: User key first, then proxy key** -- User's original API key takes precedence -- Fallback to proxy's configured keys if user's key fails -- User control with safety net -- Tradeoff: More auth logic, but better UX - -#### Integration Effects - -**Q7.1: Session tracking of routing** → **Option A: Existing sessions store last routing decision** -- Add routing decision field to existing session objects -- Minimal change, leverage current infrastructure -- Tradeoff: Session object grows, but acceptable - -**Q7.2: Existing features with routing** → **Option A: Always go through routing** -- Consistent behavior across all features -- All features benefit from intelligent routing -- Tradeoff: No bypass mechanism in current design - -**Q7.3: Multiple roles with different strategies** → **Option A: Cached per-role** -- Each role maintains its own routing cache/state -- Respects different strategies across roles -- Tradeoff: More cache storage, but necessary - -#### Migration & Compatibility - -**Q8.1: Existing roles with static model** → **Option B: Auto-upgrade to intelligent routing** -- Existing roles automatically benefit from routing -- Previously configured model becomes fallback if routing fails -- Tradeoff: Automatic behavior change, but beneficial - -**Q8.2: Proxy crashes, in-flight requests** → **Option B: Fallback to static LLM client** -- Graceful degradation, existing static routing continues -- Maximum resilience -- Tradeoff: May temporarily lose routing, but functionality preserved - -**Q8.3: Rollback strategy** → **Option A: Runtime feature flag** -- `llm_router_enabled` can be set to false at runtime -- No code deploy needed for rollback -- Instant rollback capability -- Tradeoff: Need config reload mechanism - -#### Accessibility & Internationalization - -**Q9.1: Routing decision exposure for screen readers** → **Option B: API response metadata** -- Expose in API response (developers can read) -- Screen reader users can inspect via dev tools -- UI stays simple -- Tradeoff: Not directly in UI, but accessible - -**Q9.2: Pattern language** → **Option C: Language hint metadata in taxonomy files** -- Patterns stay in English (global baseline) -- Taxonomy files include metadata for UI localization -- Routing layer unchanged -- Tradeoff: Pattern files more complex, but routing simple - -#### Operational Readiness - -**Q10.1: Metrics tracking** → **Option C: Comprehensive** -- Routing phase used, time spent routing -- Success rate per provider/model -- Cost savings (tracked vs baseline) -- Performance metrics (latency per provider) -- Fallback rates (Phase 5 usage) -- Tradeoff: Higher logging overhead, but full visibility - -**Q10.2: Alerting on routing issues** → **Option D: Alert on high fallback rate** -- Alert if fallback rate (Phase 5) exceeds threshold (e.g., >20%) -- High fallback rate means earlier phases failing -- Specific alerting for routing problems -- Tradeoff: More alerting rules, but catches routing failures - -**Q10.3: Debugging tools** → **Decision: Provide all options (A, B, C)** -- Structured logs with all phase results and scores -- Debug API endpoint to test routing without LLM calls -- Interactive routing explorer tool (CLI or web UI) -- Comprehensive debugging -- Tradeoff: More tooling to maintain - -### Deferred Items - -- **Reinforcement learning routing**: Defer to Phase 3 or future work -- **Automatic request batching**: Not included in current scope (user can batch via API) -- **Per-feature routing bypass**: All features go through routing (consistent design) -- **Multi-provider load balancing**: Deterministic routing prioritized for now - -### Interview Summary - -The specification interview successfully surfaced critical requirements and design decisions across 10 dimensions. Key findings that will significantly impact implementation: - -**Most Critical Decisions:** -1. **Graceful degradation architecture**: Multiple fallback layers (routing phases → static client) ensure maximum resilience -2. **Terraphim KG integration**: User-editable routing patterns leverage existing infrastructure, powerful customization -3. **Runtime rollback**: Feature flag enables instant rollback without code deployment -4. **Comprehensive observability**: Full logging, metrics, and alerting for production confidence -5. **Session-aware caching**: Per-role and per-session caching balances performance with adaptability - -**Architecture Implications:** -- Router must implement panic recovery to static client fallback -- Adapter layer needs credential validation before routing -- Session objects require routing decision field -- Taxonomy files need language hint metadata -- Metrics collection must track cost savings and fallback rates - -**User Experience:** -- API-level routing transparency (metadata in responses) -- Clear error messages for edge cases (unconfigured providers, oversized requests) -- Dual terminology for audience segmentation -- User-editable patterns for personalization - -**Operational Readiness:** -- <10ms routing overhead (very lenient target) -- Alerting on >20% fallback rate -- Debug API endpoint for routing testing -- Comprehensive logging with all phase decisions - -The implementation plan is now complete with specific behavioral requirements for all edge cases and failure modes. No hidden assumptions remain that would require clarification during coding. +**Note:** Service mode proxy client is stubbed - full external service mode implementation deferred to future phases based on complexity and requirements.

Integration - 2026-01-04 + +### Context: Multi-Phase Feature Implementation with Disciplined Development + +**Feature:** LLM Router with dual-mode support (Library/Service) for intelligent LLM selection across multiple providers. + +**Architecture:** +- **Library Mode**: In-process routing via `RoutedLlmClient` wrapping static LLM client +- **Service Mode**: HTTP proxy client (`ProxyLlmClient`) forwarding to external `terraphim-llm-proxy` service + +### Pattern 1: Feature-Gated Module Organization + +**What We Learned:** +- Feature flags (`#[cfg(feature = "llm_router")]`) keep production builds clean +- Module declarations must come BEFORE imports in Rust +- Submodules need proper parent module declarations + +**Implementation:** +```rust +// In llm.rs - order matters! +#[cfg(feature = "llm_router")] +mod routed_adapter; +#[cfg(feature = "llm_router")] +mod router_config; +#[cfg(feature = "llm_router")] +mod proxy_client; + +#[cfg(feature = "llm_router")] +use crate::llm::routed_adapter::RoutedLlmClient; +#[cfg(feature = "llm_router")] +use crate::llm::proxy_client::ProxyLlmClient; +``` + +**When to Apply:** Any optional feature with significant code volume. + +### Pattern 2: Configuration Re-export for Public API + +**What We Learned:** +- Private imports in submodules need `pub use` to become public +- `RouterMode` was imported privately in `router_config.rs` causing "private enum" errors +- Solution: Change `use` to `pub use` in the re-export module + +**Implementation:** +```rust +// router_config.rs - use becomes pub use +pub use terraphim_config::llm_router::{LlmRouterConfig, RouterMode, RouterStrategy}; +``` + +**When to Apply:** Configuration types that need to be accessible from parent modules. + +### Pattern 3: Test File Updates for Struct Schema Changes + +**What We Learned:** +- Adding fields to a struct requires updating ALL test initializations +- Use systematic tools (Python scripts, sed) for bulk updates +- Risk of duplicates when running fix scripts multiple times +- Better to restore files and re-run once cleanly + +**Implementation:** +```python +# Pattern for bulk Role struct updates +def fix_role_fields(content): + pattern = r'(extra:\s*(?:ahash::)?AHashMap::new\(\),)' + replacement = r'\1\n llm_router_enabled: false,\n llm_router_config: None,' + return re.sub(pattern, replacement, content) +``` + +**Anti-pattern:** Running fix scripts multiple times creates duplicate field declarations. + +**When to Apply:** Any struct schema change affecting test files across multiple crates. + +### Pattern 4: ServiceError Variant Selection + +**What We Learned:** +- `ServiceError::Network` and `ServiceError::Parsing` don't exist in this crate +- Available variants: `Middleware`, `OpenDal`, `Persistence`, `Config`, `OpenRouter`, `Common` +- Use `ServiceError::Config(String)` for proxy connection failures + +**Implementation:** +```rust +// Before (doesn't compile) +return Err(crate::ServiceError::Network(format!("Failed to connect: {}", e))); + +// After +return Err(crate::ServiceError::Config(format!("Failed to connect: {}", e))); +``` + +**When to Apply:** Error handling when adding new error scenarios. + +### Pattern 5: Submodule Import Paths in Rust + +**What We Learned:** +- `proxy_client.rs` is a submodule of `llm.rs` +- Use `super::` to access parent module items (not `super::llm::`) +- Parent module types are directly accessible: `LlmClient`, `SummarizeOptions`, `ChatOptions` + +**Implementation:** +```rust +// proxy_client.rs - correct imports +use super::LlmClient; +use super::SummarizeOptions; +use super::ChatOptions; + +// NOT super::llm::LlmClient +``` + +**When to Apply:** Any nested module structure in Rust. + +### Pattern 6: JSON Serialization Test Assertions + +**What We Learned:** +- `serde_json::to_string()` doesn't add spaces after colons +- `"model":"auto"` not `"model": "auto"` +- Test assertions must match actual serialization format + +**Implementation:** +```rust +// Before (fails) +assert!(json_str.contains("\"model\": \"auto\"")); + +// After (passes) +assert!(json_str.contains("\"model\":\"auto\"")); +``` + +**When to Apply:** Any tests checking JSON string format. + +### Pattern 7: Default Trait for Configuration Structs + +**What We Learned:** +- `#[derive(Default)]` conflicts with manual `impl Default` +- Must choose one approach +- Manual implementation allows setting custom defaults (like port 3456) + +**Implementation:** +```rust +// Before - derive conflict +#[derive(Debug, Clone, Default)] +pub struct ProxyClientConfig { ... } + +// After - manual impl without derive +#[derive(Debug, Clone)] +pub struct ProxyClientConfig { ... } + +impl Default for ProxyClientConfig { + fn default() -> Self { + Self { + base_url: "http://127.0.0.1:3456".to_string(), + timeout_secs: 60, + log_requests: false, + } + } +} +``` + +**When to Apply:** Configuration structs needing custom defaults. + +### Pattern 8: Mode-Based Client Selection + +**What We Learned:** +- Use Rust `match` for conditional client creation based on config +- Library mode: wrap existing client with routing adapter +- Service mode: create HTTP proxy client + +**Implementation:** +```rust +match router_config.mode { + RouterMode::Library => { + if let Some(static_client) = build_ollama_from_role(role) { + return Some(Arc::new(RoutedLlmClient::new(static_client, router_config))); + } + } + RouterMode::Service => { + let proxy_url = router_config.get_proxy_url(); + let proxy_config = ProxyClientConfig { + base_url: proxy_url, + timeout_secs: 60, + log_requests: true, + }; + return Some(Arc::new(ProxyLlmClient::new(proxy_config))); + } +} +``` + +**When to Apply:** Feature toggle patterns with different implementations per toggle. + +### Session Metrics + +| Metric | Value | +|--------|-------| +| Implementation Steps | 5 | +| Files Modified | 24 | +| Test Files Updated | 14 | +| Lines Added | ~200 | +| Test Results | 118 passed, 5 unrelated failures | + +### Critical Success Factors + +1. **Incremental validation**: Run tests after each fix to catch issues early +2. **Systematic updates**: Use scripts for bulk file updates, avoid manual editing +3. **Clean restores**: When scripts create duplicates, restore and re-run cleanly +4. **Build verification**: Run `cargo build --features llm_router` before tests +5. **Pre-existing failures**: Document unrelated test failures separately diff --git a/terraphim_server/tests/api_context_tests.rs

Remove duplicate llm_router fields from Role definitions - Remove duplicate llm_router_enabled and llm_router_config fields that were accidentally added after the extra field in 13 test files - Fix unused import warning in proxy_client.rs (remove std::sync::Arc) - Add #[allow(dead_code)] to proxy_client.rs methods used only in tests - Prefix unused test variables with underscore in
