+description: Query the Onyx knowledge base using the onyx-cli command. Use when the user wants to search company documents, ask questions about internal knowledge, query connected data sources, or look up information stored in Onyx.
+---
+
+# Onyx CLI — Agent Tool
+
+Onyx is an enterprise search and Gen-AI platform that connects to company documents, apps, and people. The `onyx-cli` CLI provides non-interactive commands to query the Onyx knowledge base and list available agents.
+
+## Prerequisites
+
+### 1. Check if installed
+
+```bash
+which onyx-cli
+```
+
+### 2. Install (if needed)
+
+**Primary — pip:**
+
+```bash
+pip install onyx-cli
+```
+
+**From source (Go):**
+
+```bash
+cd cli && go build -o onyx-cli . && sudo mv onyx-cli /usr/local/bin/
+```
+
+### 3. Check if configured
+
+```bash
+onyx-cli validate-config
+```
+
+This checks the config file exists, API key is present, and tests the server connection via `/api/me`. Exit code 0 on success, non-zero with a descriptive error on failure.
+
+If unconfigured, you have two options:
+
+**Option A — Interactive setup (requires user input):**
+
+```bash
+onyx-cli configure
+```
+
+This prompts for the Onyx server URL and API key, tests the connection, and saves config.
+
+**Option B — Environment variables (non-interactive, preferred for agents):**
+
+```bash
+export ONYX_SERVER_URL="https://your-onyx-server.com"  # default: https://cloud.onyx.app
+export ONYX_API_KEY="your-api-key"
+```
+
+Environment variables override the config file. If these are set, no config file is needed.
+
+| Variable | Required | Description |
+|----------|----------|-------------|
+| `ONYX_SERVER_URL` | No | Onyx server base URL (default: `https://cloud.onyx.app`) |
+| `ONYX_API_KEY` | Yes | API key for authentication |
+| `ONYX_PERSONA_ID` | No | Default agent/persona ID |
+
+If neither the config file nor environment variables are set, tell the user that `onyx-cli` needs to be configured and ask them to either:
+- Run `onyx-cli configure` interactively, or
+- Set `ONYX_SERVER_URL` and `ONYX_API_KEY` environment variables
+
+## Commands
+
+### Validate configuration
+
+```bash
+onyx-cli validate-config
+```
+
+Checks config file exists, API key is present, and tests the server connection. Use this before `ask` or `agents` to confirm the CLI is properly set up.
+
+### List available agents
+
+```bash
+onyx-cli agents
+```
+
+Prints a table of agent IDs, names, and descriptions. Use `--json` for structured output:
+
+```bash
+onyx-cli agents --json
+```
+
+Use agent IDs with `ask --agent-id` to query a specific agent.
+
+### Basic query (plain text output)
+
+```bash
+onyx-cli ask "What is our company's PTO policy?"
+```
+
+Streams the answer as plain text to stdout. Exit code 0 on success, non-zero on error.
+
+### JSON output (structured events)
+
+```bash
+onyx-cli ask --json "What authentication methods do we support?"
+```
+
+Outputs JSON-encoded parsed stream events (one object per line). Key event objects include message deltas, stop, errors, search-start, and citation payloads.
+
+| Event Type | Description |
+|------------|-------------|
+| `message_delta` | Content token — concatenate all `content` fields for the full answer |
+| `stop` | Stream complete |
+| `error` | Error with `error` message field |
+| `search_tool_start` | Onyx started searching documents |
+| `citation_info` | Source citation with `citation_number` and `document_id` |
+
+### Specify an agent
+
+```bash
+onyx-cli ask --agent-id 5 "Summarize our Q4 roadmap"
+```
+
+Uses a specific Onyx agent/persona instead of the default.
+
+### All flags
+
+| Flag | Type | Description |
+|------|------|-------------|
+| `--agent-id` | int | Agent ID to use (overrides default) |
+| `--json` | bool | Output raw NDJSON events instead of plain text |
+
+## When to Use
+
+Use `onyx-cli ask` when:
+
+- The user asks about company-specific information (policies, docs, processes)
+- You need to search internal knowledge bases or connected data sources
+- The user references Onyx, asks you to "search Onyx", or wants to query their documents
+- You need context from company wikis, Confluence, Google Drive, Slack, or other connected sources
+
+Do NOT use when:
+
+- The question is about general programming knowledge (use your own knowledge)
+- The user is asking about code in the current repository (use grep/read tools)
+- The user hasn't mentioned Onyx and the question doesn't require internal company data
+
+## Examples
+
+```bash
+# Simple question
+onyx-cli ask "What are the steps to deploy to production?"
+
+# Get structured output for parsing
+onyx-cli ask --json "List all active API integrations"
+
+# Use a specialized agent
+onyx-cli ask --agent-id 3 "What were the action items from last week's standup?"
+
+# Pipe the answer into another command
+onyx-cli ask "What is the database schema for users?" | head -20
+```

-#### Worker Deployment Modes
-
-Onyx supports two deployment modes for background workers, controlled by the `USE_LIGHTWEIGHT_BACKGROUND_WORKER` environment variable:
-
-**Lightweight Mode** (default, `USE_LIGHTWEIGHT_BACKGROUND_WORKER=true`):
-
-- Runs a single consolidated `background` worker that handles all background tasks:
-  - Light worker tasks (Vespa operations, permissions sync, deletion)
-  - Document processing (indexing pipeline)
-  - Document fetching (connector data retrieval)
-  - Pruning operations (from `heavy` worker)
-  - Knowledge graph processing (from `kg_processing` worker)
-  - Monitoring tasks (from `monitoring` worker)
-  - User file processing (from `user_file_processing` worker)
-- Lower resource footprint (fewer worker processes)
-- Suitable for smaller deployments or development environments
-- Default concurrency: 20 threads (increased to handle combined workload)
-
-**Standard Mode** (`USE_LIGHTWEIGHT_BACKGROUND_WORKER=false`):
-
-- Runs separate specialized workers as documented above (light, docprocessing, docfetching, heavy, kg_processing, monitoring, user_file_processing)
-- Better isolation and scalability
-- Can scale individual workers independently based on workload
-- Suitable for production deployments with higher load
-
-The deployment mode affects:
-
-- **Backend**: Worker processes spawned by supervisord or dev scripts
-- **Helm**: Which Kubernetes deployments are created
-- **Dev Environment**: Which workers `dev_run_background_jobs.py` spawns

+## Error Handling
+
+**Always raise `OnyxError` from `onyx.error_handling.exceptions` instead of `HTTPException`.
+Never hardcode status codes or use `starlette.status` / `fastapi.status` constants directly.**
+
+A global FastAPI exception handler converts `OnyxError` into a JSON response with the standard
+`{"error_code": "...", "message": "..."}` shape. This eliminates boilerplate and keeps error
+handling consistent across the entire backend.
+
+```python
+from onyx.error_handling.error_codes import OnyxErrorCode
+from onyx.error_handling.exceptions import OnyxError
+
+# ✅ Good
+raise OnyxError(OnyxErrorCode.NOT_FOUND, "Session not found")
+
+# ✅ Good — no extra message needed
+raise OnyxError(OnyxErrorCode.UNAUTHENTICATED)
+
+# ✅ Good — upstream service with dynamic status code
+raise OnyxError(OnyxErrorCode.BAD_GATEWAY, detail, status_code_override=upstream_status)
+
+# ❌ Bad — using HTTPException directly
+raise HTTPException(status_code=404, detail="Session not found")
+
+# ❌ Bad — starlette constant
+raise HTTPException(status_code=status.HTTP_403_FORBIDDEN, detail="Access denied")
+```
+
+Available error codes are defined in `backend/onyx/error_handling/error_codes.py`. If a new error
+category is needed, add it there first — do not invent ad-hoc codes.
+
+**Upstream service errors:** When forwarding errors from an upstream service where the HTTP
+status code is dynamic (comes from the upstream response), use `status_code_override`:
+
+```python
+raise OnyxError(OnyxErrorCode.BAD_GATEWAY, detail, status_code_override=e.response.status_code)
+```
