The local `StateGraph`/`AgentGraph` API mirrors the required LangGraph concepts: typed state, nodes, ordinary and conditional edges, checkpoint persistence, resume, and node-level retries. Keeping it avoids adding a new runtime dependency or changing the established checkpoint and streaming behavior; the public harness boundary can be migrated later if the platform adopts the package.

(`/services/agents`) -Part of the AI-RxOS platform. See `/architecture` at the repo root for the -full service contract this implements. Runs on port **8085**. +## Overview + +The `agents` service is the central AI Platform component for the AI-RxOS platform, providing agent execution, multi-agent orchestration, tenant-isolated memory management, prompt versioning, tool registration, and provider-agnostic model access across port **8085**. + +## LangGraph Runtime + +This service uses the official `langgraph` package as the graph runtime backing the agent harness in `app/agent_harness/graph.py` while preserving the repository's existing checkpoint, security, and job execution contracts. + +* **Runtime Compliance**: The harness is backed by `langgraph.graph.StateGraph`, with the repository-specific `AgentState`, `AgentRuntime`, `RedisCheckpointStore`, and worker orchestration layered on top so the public API remains stable. +* **Execution**: `AgentGraph.run()` invokes the compiled LangGraph graph with `ainvoke()`. Node adapters preserve retry policies, transition limits, tenant memory attachment, lifecycle events, and checkpoint persistence without maintaining a second graph execution loop. + +The production API wiring uses `RedisCheckpointStore` and applies the +`AGENT_MAX_TRANSITIONS` budget (default `100`). Async jobs are submitted to a +Redis Streams consumer group and executed by `python -m app.jobs.worker`. + +Workers reclaim pending messages after `AGENT_WORKER_RECLAIM_IDLE_SECONDS` +(default `60`) using `XAUTOCLAIM`. A per-task Redis lock prevents concurrent +execution during recovery. `AGENT_WORKER_EXECUTION_TIMEOUT_SECONDS` bounds a +job and `AGENT_WORKER_LOCK_TTL_SECONDS` bounds ownership (the default is `390`, +which exceeds the default execution plus reclaim windows). Task transitions are +durable and terminal tasks are acknowledged without re-execution. Cancellation +is requested with `POST /api/v1/agents/tasks/{task_id}/cancel` and is observed +by queued, retrying, and in-flight executions. + +Worker recovery tests are separated by evidence level: `tests/test_worker_recovery.py` +is deterministic local coverage; `tests/live/test_live_worker_recovery.py` uses +the configured Redis service when `AI_RXOS_LIVE_WORKER_TESTS=1`; a full +multi-process crash test requires a deployed worker command and is not run by +default. Configure `AGENT_WORKER_RECLAIM_IDLE_SECONDS`, +`AGENT_WORKER_EXECUTION_TIMEOUT_SECONDS`, `AGENT_WORKER_LOCK_TTL_SECONDS`, and +`REDIS_OPERATION_TIMEOUT_SECONDS` in production. + +### Durable Execution Payloads + +Operational Redis task and checkpoint records contain metadata and references +only. Request input, intermediate state, tool data, and results are stored in +`RedisExecutionPayloadStore` under tenant/workspace-scoped keys and encrypted +with Fernet. Configure `EXECUTION_PAYLOAD_KEY` with a stable production key; +the service fails closed if the development fallback is used in production. Workers and graph +resume operations hydrate payloads only after applying the tenant/workspace +scope. + +--- + +## Architecture Summary + +### 1. Model Registry (`app/model_registry`) +Provides a provider-neutral abstraction layer over LLM providers (OpenAI, Anthropic, Google Generative Language, and self-hosted HuggingFace TGI endpoints). Supports configurable model request parameters, token streaming, per-model timeout enforcement, and automated fallback execution across ordered fallback model chains. + +### 2. Prompt Registry (`app/prompt_registry`) +Manages versioned prompt templates with string variable interpolation (`Template.substitute`), auto-incrementing version assignment, and flexible storage options (`InMemoryPromptStore` and `RedisPromptStore`). + +### 3. Tool Registry (`app/tool_registry`) +Handles local and remote tool registration, input and output JSON Schema validation, sync/async handler execution, execution timeouts, authorization policies, retry-mode declarations, and automatic MCP tool schema conversion. + +### 4. LangGraph Agent Harness (`app/agent_harness`) +Built on the official `langgraph.graph.StateGraph` and a compatibility facade that adapts the typed `AgentState` model, node handlers, conditional routing, Redis checkpoint persistence, retries, and bounded `ainvoke()` execution. A resume entry node routes a recovered run to its persisted `current_node`; the LangGraph recursion limit bounds cyclic graphs. + +### 5. Multi-Agent Orchestrator (`app/multi_agent`) +Implements supervisor-driven multi-agent routing via `MultiAgentOrchestrator`. Supports `AgentOutcome` state updates, sequential agent handoffs (`Handoff`), and concurrent parallel execution of independent agents via `run_parallel()`. + +### 6. Memory Architecture (`app/memory`) +Provides a unified memory access layer via the `create_agent_memory()` factory, used consistently by both API endpoints (`app/routers/memory.py`) and active graph execution runs. +- **Short-Term & Chat Context**: `AgentMemory` handles run-scoped short-term dictionary storage, backed by Redis for tenant/workspace key indexing (`agent:memory:{org}:{workspace}:{agent_id}:{key}`). `ConversationMemoryStore` manages Redis-backed sliding window chat history (`agent:context:{conversation_id}`). +- **Long-Term Persistence**: Delegated to `LLMWikiMemoryAdapter`, compiling document summaries into external LLM Wiki pages via `/api/v1/wiki/compile` and retrieving via `/api/v1/wiki/pages`. +- **Per-Run Isolation**: `AgentRuntime` uses Python `ContextVar` instances (`_memory` and `_event_sink`) to guarantee that memory context and telemetry sinks remain strictly isolated per async execution context. + +### 7. Planning & Reasoning (`app/agent_harness/planning.py`) +Provides reusable `PlanExecuteNodes` for task decomposition and execution. Generates structured `ExecutionPlan` steps, tracks step progress, triggers replanning upon step failure, and performs model-backed reflection (`reflect()`) to evaluate output satisfaction. + +### 8. Streaming (`app/routers/streaming.py`) +Exposes `POST /api/v1/agents/stream`, yielding Server-Sent Events (SSE) for graph lifecycle starts, live LLM output tokens, tool call executions, tool results, and multi-agent handoff updates. + +### 9. MCP Client (`app/tool_registry/mcp_client.py`) +MCP JSON-RPC 2.0 HTTP client supporting `initialize`, `tools/list`, and `tools/call`. Maintains `Mcp-Session-Id` header persistence, applies bounded timeouts and transient-only reconnects, validates protocol and SSE responses, and consumes streaming tool output into redacted metadata events. Imported tools execute through `ToolRegistry`, which enforces agent, permission, organization, and workspace authorization before every call. + +### 10. Async Job Execution (`app/main.py`) +Supports asynchronous background execution by invoking `POST /api/v1/agents/invoke` with `async_mode: true`. The API stores a tenant-scoped task record and enqueues its ID on the `agents:jobs` Redis Stream. A consumer-group worker claims, executes, retries, recovers stale messages, and acknowledges jobs. `Idempotency-Key` prevents duplicate submissions within a tenant scope. + +--- + +## Concurrency & Isolation Guarantees + +The service enforces strict tenant and run isolation: +- **Thread/Task Isolation**: `AgentRuntime` utilizes Python `ContextVar`s for `_memory` and `_event_sink`. Concurrent graph runs sharing a single `AgentRuntime` instance cannot access or leak memory contexts, event listeners, or telemetry streams across tasks. +- **Tenant Isolation**: Conversation history and memory stores require explicit `TenantContext` parameters (`organization_id`, `workspace_id`), enforcing isolated Redis keys and forbidding cross-tenant data access. +- **Task Isolation**: Async task keys (`agents:task:{id}`) operate on unique UUID task IDs. + +*Verification*: Dedicated concurrency tests in [`tests/test_memory_access_consistency.py`](file:///c:/Users/Lenovo/Downloads/AI-RxOS/services/agents/tests/test_memory_access_consistency.py) verify that parallel graph runs sharing runtime instances operate without cross-talk or state leakage. + +--- + +## API Reference + +| Endpoint | Method | Description | +| :--- | :---: | :--- | +| `/healthz` | `GET` | Health check endpoint returning status and service name. | +| `/api/v1/agents/invoke` | `POST` | Invokes an agent task synchronously or asynchronously (`async_mode: true`). | +| `/api/v1/agents/tasks/{task_id}` | `GET` | Polls the current status, step progress, and results of an async agent task. | +| `/api/v1/tools` | `GET` | Lists all registered tools and their input/output JSON schemas. | +| `/api/v1/agents/memory` | `POST / GET` | Stores, retrieves, or searches tenant-isolated agent memory entries. | +| `/api/v1/agents/conversations` | `POST / GET` | Appends messages to or retrieves sliding window chat history for a conversation. | +| `/api/v1/agents/stream` | `POST` | Streams live SSE events (`node_started`, `token`, `tool_call`, `run_completed`) for graph execution. | +| `/metrics` | `GET` | Exposes basic Prometheus-compatible request and error counters. | + +--- + +## How to Run + +### Installation ```bash +cd services/agents pip install -r requirements.txt -uvicorn app.main:app --reload --port 8085 ``` -## AI Platform +### Environment Variables + +| Variable | Required | Default | Description | +| :--- | :---: | :--- | :--- | +| `REDIS_URL` | No | `redis://localhost:6379/0` | Connection string for Redis cache, tasks, and graph checkpoints. | +| `AGENT_MAX_TRANSITIONS` | No | `100` | Maximum graph node transitions per run. | +| `AGENT_MAX_RETRIES` | No | `3` | Maximum worker retries after a failed job. | +| `LLM_WIKI_URL` | No | `None` | Base URL for external LLM Wiki service long-term memory. | +| `OPENAI_API_KEY` | No | `None` | API key for OpenAI provider adapter. | +| `ANTHROPIC_API_KEY` | No | `None` | API key for Anthropic provider adapter. | +| `GOOGLE_API_KEY` | No | `None` | API key for Google Generative Language provider adapter. | +| `MODEL_NAME` | No | `gpt-4o-mini` | Default primary model name. | +| `MODEL_PROVIDER` | No | `openai` | Default primary model provider. | +| `ALLOWED_AGENT_TYPES` | No | `default` | Comma-separated agent allowlist. | + +Provider model registry entries may omit `api_key`; the service resolves +credentials from `OPENAI_API_KEY`, `ANTHROPIC_API_KEY`, `GOOGLE_API_KEY`, or +`OPEN_SOURCE_API_KEY` according to the provider.

Logging emits structured run/node events; `telemetry_hook` is reserved for future OpenTelemetry integration. +--- -### LangGraph Decision +## Known Limitations -**Option (b): retain the custom runtime.** This service does not currently depend on the external `langgraph` package. The local `StateGraph`/`AgentGraph` API mirrors the required LangGraph concepts: typed state, nodes, ordinary and conditional edges, checkpoint persistence, resume, and node-level retries. Keeping it avoids adding a new runtime dependency or changing the established checkpoint and streaming behavior; the public harness boundary can be migrated later if the platform adopts the package. +1. **MCP Session Restarts**: `MCPClient` maintains `Mcp-Session-Id` headers during active runtime connections and automatically reconnects on network drops. However, session state does not persist across service process restarts. +2. **JSON Schema Validation Subset**: Tool input/output validation (`app/tool_registry/validation.py`) enforces a practical subset of JSON Schema validation (type checking, object properties, required fields, array items) rather than the full JSON Schema Draft 2020-12 spec. +3. **Mocked Provider Integration Tests**: Unit and integration tests for model providers use local HTTP mocks (`httpx.MockTransport`). No live third-party API credential calls are executed during standard automated test runs. +4. **Prompt Injection Mitigation Boundary**: Structural role separation (placing system instructions into dedicated `system` role messages) and XML-delimited `` tags are implemented in `AgentRuntime.build_structured_messages()` to establish role boundaries for LLMs. Note that structural role separation and XML delimiting reduce but do not eliminate prompt injection risk — it is one defense-in-depth mitigation layer, not a complete solution. +5. **Worker recovery boundary**: Redis Streams retain queued and acknowledged state. A worker crash leaves an in-flight message pending; another worker can reclaim it after the idle timeout. Non-idempotent tools disable automatic job retry; tools requiring idempotency keys receive stable keys derived from tenant, run, tool, and arguments. +6. **Authorization boundary**: JWT roles and permissions are consumed when present through `AuthorizationService`; agent allowlists and tool policies remain registry/configuration based because this service has no separate Better Auth permission API. +7. **Observability boundary**: Opaque request/correlation IDs, low-cardinality + lifecycle counters, request latency histograms, and optional OpenTelemetry + tracing are implemented. Token usage and cost accounting are not configured. diff --git a/services/agents/TESTING.md b/services/agents/TESTING.md new file mode 100644 index 0000000..68d81bb --- /dev/null +++ b/services/agents/TESTING.md @@ -0,0 +1,158 @@ +# Test Coverage Mapping & Verification (`/services/agents`) + +The agents API requires bearer JWT authentication for invocation, task polling, +tool discovery, and streaming.
