+# WebSearch Interception Architecture
+
+Server-side WebSearch tool execution for models that don't natively support it (e.g., Bedrock/Claude).
+
+## How It Works
+
+User makes **ONE** `litellm.messages.acreate()` call → Gets final answer with search results.
+The agentic loop happens transparently on the server.
+
+## LiteLLM Standard Web Search Tool
+
+LiteLLM defines a standard web search tool format (`litellm_web_search`) that all native provider tools are converted to. This enables consistent interception across providers.
+
+**Standard Tool Definition** (defined in `tools.py`):
+```python
+{
+ "name": "litellm_web_search",
+ "description": "Search the web for information...",
+ "input_schema": {
+ "type": "object",
+ "properties": {
+ "query": {"type": "string", "description": "The search query"}
+ },
+ "required": ["query"]
+ }
+}
+```
+
+**Tool Name Constant**: `LITELLM_WEB_SEARCH_TOOL_NAME = "litellm_web_search"` (defined in `litellm/constants.py`)
+
+### Supported Tool Formats
+
+The interception system automatically detects and handles:
+
+| Tool Format | Example | Provider | Detection Method | Future-Proof |
+|-------------|---------|----------|------------------|-------------|
+| **LiteLLM Standard** | `name="litellm_web_search"` | Any | Direct name match | N/A |
+| **Anthropic Native** | `type="web_search_20250305"` | Bedrock, Claude API | Type prefix: `startswith("web_search_")` | ✅ Yes (web_search_2026, etc.) |
+| **Claude Code CLI** | `name="web_search"`, `type="web_search_20250305"` | Claude Code | Name + type check | ✅ Yes (version-agnostic) |
+| **Legacy** | `name="WebSearch"` | Custom | Name match | N/A (backwards compat) |
+
+**Future Compatibility**: The `startswith("web_search_")` check in `tools.py` automatically supports future Anthropic web search versions.
+
+### Claude Code CLI Integration
+
+Claude Code (Anthropic's official CLI) sends web search requests using Anthropic's native tool format:
+
+```python
+{
+ "type": "web_search_20250305",
+ "name": "web_search",
+ "max_uses": 8
+}
+```
+
+**What Happens:**
+1. Claude Code sends native `web_search_20250305` tool to LiteLLM proxy
+2. LiteLLM intercepts and converts to `litellm_web_search` standard format
+3. Bedrock receives converted tool (NOT native format)
+4. Model returns `tool_use` block for `litellm_web_search` (not `server_tool_use`)
+5. LiteLLM's agentic loop intercepts the `tool_use`
+6. Executes `litellm.asearch()` using configured provider (Perplexity, Tavily, etc.)
+7. Returns final answer to Claude Code user
+
+**Without Interception**: Bedrock would receive native tool → try to execute natively → return `web_search_tool_result_error` with `invalid_tool_input`
+
+**With Interception**: LiteLLM converts → Bedrock returns tool_use → LiteLLM executes search → Returns final answer ✅
+
+### Native Tool Conversion
+
+Native tools are converted to LiteLLM standard format **before** sending to the provider:
+
+1. **Conversion Point** (`litellm/llms/anthropic/experimental_pass_through/messages/handler.py`):
+ - In `anthropic_messages()` function (lines 60-127)
+ - Runs BEFORE the API request is made
+ - Detects native web search tools using `is_web_search_tool()`
+ - Converts to `litellm_web_search` format using `get_litellm_web_search_tool()`
+ - Prevents provider from executing search natively (avoids `web_search_tool_result_error`)
+
+2. **Response Detection** (`transformation.py`):
+ - Detects `tool_use` blocks with any web search tool name
+ - Handles: `litellm_web_search`, `WebSearch`, `web_search`
+ - Extracts search queries for execution
+
+**Example Conversion**:
+```python
+# Input (Claude Code's native tool)
+{
+ "type": "web_search_20250305",
+ "name": "web_search",
+ "max_uses": 8
+}
+
+# Output (LiteLLM standard)
+{
+ "name": "litellm_web_search",
+ "description": "Search the web for information...",
+ "input_schema": {...}
+}
+```
+
+---
+
+## Request Flow
+
+### Without Interception (Client-Side)
+User manually handles tool execution:
+1. User calls `litellm.messages.acreate()` → Gets `tool_use` response
+2. User executes `litellm.asearch()`
+3. User calls `litellm.messages.acreate()` again with results
+4. User gets final answer
+
+**Result**: 2 API calls, manual tool execution
+
+### With Interception (Server-Side)
+Server handles tool execution automatically:
+
+```mermaid
+sequenceDiagram
+ participant User
+ participant Messages as litellm.messages.acreate()
+ participant Handler as llm_http_handler.py
+ participant Logger as WebSearchInterceptionLogger

+
+## Configuration
+
+```python
+from litellm.integrations.websearch_interception import (
+ WebSearchInterceptionLogger,
+ get_litellm_web_search_tool,
+)
+from litellm.types.utils import LlmProviders
+
+# Enable for Bedrock with specific search tool
+litellm.callbacks = [
+ WebSearchInterceptionLogger(
+ enabled_providers=[LlmProviders.BEDROCK],
+ search_tool_name="my-perplexity-tool" # Optional: uses router's first tool if None
+ )
+]
+
+# Make request with LiteLLM standard tool (recommended)
+response = await litellm.messages.acreate(
+ model="bedrock/us.anthropic.claude-sonnet-4-5-20250929-v1:0",
+ messages=[{"role": "user", "content": "What is LiteLLM?"}],
+ tools=[get_litellm_web_search_tool()], # LiteLLM standard
+ max_tokens=1024,
+ stream=True # Auto-converted to non-streaming
+)
+
+# OR send native tools - they're auto-converted to LiteLLM standard
+response = await litellm.messages.acreate(
+ model="bedrock/us.anthropic.claude-sonnet-4-5-20250929-v1:0",
+ messages=[{"role": "user", "content": "What is LiteLLM?"}],
+ tools=[{
+ "type": "web_search_20250305", # Native Anthropic format
+ "name": "web_search",
+ "max_uses": 8
+ }],
+ max_tokens=1024,
+)
+```
+
+---
+
+## Streaming Support
+
+WebSearch interception works transparently with both streaming and non-streaming requests.
+
+**How streaming is handled:**
+1. User makes request with `stream=True` and WebSearch tool
+2. Before API call, `anthropic_messages()` detects WebSearch + interception enabled
+3. Converts `stream=True` → `stream=False` internally
+4. Agentic loop executes with non-streaming responses
+5. Final response returned to user (non-streaming)
+
+**Why this approach:**
+- Server-side agentic loops require consuming full responses to detect tool_use
+- User opts into this behavior by enabling WebSearch interception
+- Provides seamless experience without client changes
+
+**Testing:**
+- **Non-streaming**: `test_websearch_interception_e2e.py`
+- **Streaming**: `test_websearch_interception_streaming_e2e.py`
+
+---
+
+## Search Provider Selection
+
+1. If `search_tool_name` specified → Look up in `llm_router.search_tools`
+2. If not found or None → Use first available search tool
+3. If no router or no tools → Fallback to `perplexity`
+
+Example router config:
+```yaml
+search_tools:
+ - search_tool_name: "my-perplexity-tool"
+ litellm_params:
+ search_provider: "perplexity"
+ - search_tool_name: "my-tavily-tool"
+ litellm_params:
+ search_provider: "tavily"
+```
+
+---
+
+## Message Flow
+
+### Initial Request
+```python
+messages = [{"role": "user", "content": "What is LiteLLM?"}]
+tools = [{"name": "WebSearch", ...}]
+```
+
+### First API Call (Internal)
+**Response**: `tool_use` with `name="WebSearch"`, `input={"query": "what is litellm"}`
+
+### Server Processing
+1. Logger detects WebSearch tool_use
+2. Looks up search provider from router
+3. Executes `litellm.asearch(query="what is litellm", search_provider="perplexity")`
+4. Gets results: `"Title: LiteLLM Docs\nURL: docs.litellm.ai\n..."`
+
+### Follow-Up Request (Internal)
+```python
+messages = [
+ {"role": "user", "content": "What is LiteLLM?"},
+ {"role": "assistant", "content": [{"type": "tool_use", ...}]},
+ {"role": "user", "content": [{"type": "tool_result", "content": "search results..."}]}
+]
+```
+
+### User Receives
+```python
+response.content[0].text
+# "Based on the search results, LiteLLM is a unified interface..."
+```
+
+---
+
+## Testing
+
+**E2E Tests**:
+- `test_websearch_interception_e2e.py` - Non-streaming real API calls to Bedrock
+- `test_websearch_interception_streaming_e2e.py` - Streaming real API calls to Bedrock
+
+**Unit Tests**: `test_websearch_interception.py`
+Mocked tests for tool detection, provider filtering, edge cases.

+# A2A Protocol Guardrail Translation Handler
+
+Handler for processing A2A (Agent-to-Agent) Protocol messages with guardrails.
+
+## Overview
+
+This handler processes A2A JSON-RPC 2.0 input/output by:
+1. Extracting text from message parts (`kind: "text"`)
+2. Applying guardrails to text content
+3. Mapping guardrailed text back to original structure
+
+## A2A Protocol Format
+
+### Input Format (JSON-RPC 2.0)
+
+```json
+{
+ "jsonrpc": "2.0",
+ "id": "request-id",
+ "method": "message/send",
+ "params": {
+ "message": {
+ "kind": "message",
+ "messageId": "...",
+ "role": "user",
+ "parts": [
+ {"kind": "text", "text": "Hello, my SSN is 123-45-6789"}
+ ]
+ },
+ "metadata": {
+ "guardrails": ["block-ssn"]
+ }
+ }
+}
+```
+
+### Output Formats
+
+The handler supports multiple A2A response formats:
+
+**Direct message:**
+```json
+{
+ "result": {
+ "kind": "message",
+ "parts": [{"kind": "text", "text": "Response text"}]
+ }
+}
+```
+
+**Nested message:**
+```json
+{
+ "result": {
+ "message": {
+ "parts": [{"kind": "text", "text": "Response text"}]
+ }
+ }
+}
+```
+
+**Task with artifacts:**
+```json
+{
+ "result": {
+ "kind": "task",
+ "artifacts": [
+ {"parts": [{"kind": "text", "text": "Artifact text"}]}
+ ]
+ }
+}
+```
+
+**Task with status message:**
+```json
+{
+ "result": {
+ "kind": "task",
+ "status": {
+ "message": {
+ "parts": [{"kind": "text", "text": "Status message"}]
+ }
+ }
+ }
+}
+```
+
+**Streaming artifact-update:**
+```json
+{
+ "result": {
+ "kind": "artifact-update",
+ "artifact": {
+ "parts": [{"kind": "text", "text": "Streaming text"}]
+ }
+ }
+}
+```
+
+## Usage
+
+The handler is automatically discovered and applied when guardrails are used with A2A endpoints.
+
+### Via LiteLLM Proxy
+
+```bash
+curl -X POST 'http://localhost:4000/a2a/my-agent' \
+-H 'Content-Type: application/json' \
+-H 'Authorization: Bearer your-api-key' \
+-d '{
+ "jsonrpc": "2.0",
+ "id": "1",
+ "method": "message/send",
+ "params": {
+ "message": {
+ "kind": "message",
+ "messageId": "msg-1",
+ "role": "user",
+ "parts": [{"kind": "text", "text": "Hello, my SSN is 123-45-6789"}]
+ },
+ "metadata": {
+ "guardrails": ["block-ssn"]
+ }
+ }
+}'
+```
+
+### Specifying Guardrails
+
+Guardrails can be specified in the A2A request via the `metadata.guardrails` field:
+
+```json
+{
+ "params": {
+ "message": {...},
+ "metadata": {
+ "guardrails": ["block-ssn", "pii-filter"]
+ }
+ }
+}
+```
+
+## Extension
+
+Override these methods to customize behavior:
+
+- `_extract_texts_from_result()`: Custom text extraction from A2A responses
+- `_extract_texts_from_parts()`: Custom text extraction from message parts
+- `_apply_text_to_path()`: Custom application of guardrailed text
+
+## Call Types
+
+This handler is registered for:
+- `CallTypes.send_message`: Synchronous A2A message sending
+- `CallTypes.asend_message`: Asynchronous A2A message sending

+CHATGPT_DEFAULT_INSTRUCTIONS = """You are Codex, based on GPT-5. You are running as a coding agent in the Codex CLI on a user's computer.
+
+## General
+
+- When searching for text or files, prefer using `rg` or `rg --files` respectively because `rg` is much faster than alternatives like `grep`. (If the `rg` command is not found, then use alternatives.)
+
+## Editing constraints
+
+- Default to ASCII when editing or creating files. Only introduce non-ASCII or other Unicode characters when there is a clear justification and the file already uses them.
+- Add succinct code comments that explain what is going on if code is not self-explanatory. You should not add comments like "Assigns the value to the variable", but a brief comment might be useful ahead of a complex code block that the user would otherwise have to spend time parsing out. Usage of these comments should be rare.
+- Try to use apply_patch for single file edits, but it is fine to explore other options to make the edit if it does not work well. Do not use apply_patch for changes that are auto-generated (i.e. generating package.json or running a lint or format command like gofmt) or when scripting is more efficient (such as search and replacing a string across a codebase).
+- You may be in a dirty git worktree.
+ * NEVER revert existing changes you did not make unless explicitly requested, since these changes were made by the user.
+ * If asked to make a commit or code edits and there are unrelated changes to your work or changes that you didn't make in those files, don't revert those changes.
+ * If the changes are in files you've touched recently, you should read carefully and understand how you can work with the changes rather than reverting them.
+ * If the changes are in unrelated files, just ignore them and don't revert them.
+- Do not amend a commit unless explicitly requested to do so.
+- While you are working, you might notice unexpected changes that you didn't make. If this happens, STOP IMMEDIATELY and ask the user how they would like to proceed.
+- **NEVER** use destructive commands like `git reset --hard` or `git checkout --` unless specifically requested or approved by the user.
+
+## Plan tool
+
+When using the planning tool:
+- Skip using the planning tool for straightforward tasks (roughly the easiest 25%).
+- Do not make single-step plans.
+- When you made a plan, update it after having performed one of the sub-tasks that you shared on the plan.
+
+## Special user requests
+
+- If the user makes a simple request (such as asking for the time) which you can fulfill by running a terminal command (such as `date`), you should do so.
+- If the user asks for a "review", default to a code review mindset: prioritise identifying bugs, risks, behavioural regressions, and missing tests. Findings must be the primary focus of the response - keep summaries or overviews brief and only after enumerating the issues. Present findings first (ordered by severity with file/line references), follow with open questions or assumptions, and offer a change-summary only as a secondary detail. If no findings are discovered, state that explicitly and mention any residual risks or testing gaps.
+
+## Frontend tasks
+When doing frontend design tasks, avoid collapsing into "AI slop" or safe, average-looking layouts.
+Aim for interfaces that feel intentional, bold, and a bit surprising.
+- Typography: Use expressive, purposeful fonts and avoid default stacks (Inter, Roboto, Arial, system).
+- Color & Look: Choose a clear visual direction; define CSS variables; avoid purple-on-white defaults. No purple bias or dark mode bias.
+- Motion: Use a few meaningful animations (page-load, staggered reveals) instead of generic micro-motions.
+- Background: Don't rely on flat, single-color backgrounds; use gradients, shapes, or subtle patterns to build atmosphere.
+- Overall: Avoid boilerplate layouts and interchangeable UI patterns. Vary themes, type families, and visual languages across outputs.
+- Ensure the page loads properly on both desktop and mobile
+
+Exception: If working within an existing website or design system, preserve the established patterns, structure, and visual language.
+
+## Presenting your work and final message
+
+You are producing plain text that will later be styled by the CLI. Follow these rules exactly. Formatting should make results easy to scan, but not feel mechanical. Use judgment to decide how much structure adds value.
+
+- Default: be very concise; friendly coding teammate tone.
+- Ask only when needed; suggest ideas; mirror the user's style.
+- For substantial work, summarize clearly; follow final-answer formatting.
+- Skip heavy formatting for simple confirmations.
+- Don't dump large files you've written; reference paths only.
+- No "save/copy this file" - User is on the same machine.
+- Offer logical next steps (tests, commits, build) briefly; add verify steps if you couldn't do something.
+- For code changes:
+ * Lead with a quick explanation of the change, and then give more details on the context covering where and why a change was made. Do not start this explanation with "summary", just jump right in.
+ * If there are natural next steps the user may want to take, suggest them at the end of your response. Do not make suggestions if there are no natural next steps.
+ * When suggesting multiple options, use numeric lists for the suggestions so the user can quickly respond with a single number.
+- The user does not command execution outputs. When asked to show the output of a command (e.g. `git show`), relay the important details in your answer or summarize the key lines so the user understands the result.
+
+### Final answer structure and style guidelines
+
+- Plain text; CLI handles styling. Use structure only when it helps scanability.
+- Headers: optional; short Title Case (1-3 words) wrapped in **...**; no blank line before the first bullet; add only if they truly help.
+- Bullets: use - ; merge related points; keep to one line when possible; 4-6 per list ordered by importance; keep phrasing consistent.
+- Monospace: backticks for commands/paths/env vars/code ids and inline examples; use for literal keyword bullets; never combine with **.
+- Code samples or multi-line snippets should be wrapped in fenced code blocks; include an info string as often as possible.
+- Structure: group related bullets; order sections general -> specific -> supporting; for subsections, start with a bolded keyword bullet, then items; match complexity to the task.
+- Tone: collaborative, concise, factual; present tense, active voice; self-contained; no "above/below"; parallel wording.
+- Don'ts: no nested bullets/hierarchies; no ANSI codes; don't cram unrelated keywords; keep keyword lists short--wrap/reformat if long; avoid naming formatting styles in answers.
+- Adaptation: code explanations -> precise, structured with code refs; simple tasks -> lead with outcome; big changes -> logical walkthrough + rationale + next actions; casual one-offs -> plain sentences, no headers/bullets.
+- File References: When referencing files in your response follow the below rules:
+ * Use inline code to make file paths clickable.
+ * Each reference should have a stand alone path. Even if it's the same file.
+ * Accepted: absolute, workspace-relative, a/ or b/ diff prefixes, or bare filename/suffix.
+ * Optionally include line/column (1-based): :line[:column] or #Lline[Ccolumn] (column defaults to 1).
+ * Do not use URIs like file://, vscode://, or https://.
+ * Do not provide range of lines
+ * Examples: src/app.ts, src/app.ts:42, b/server/index.js#L10, C:\\repo\\project\\main.rs:12:5

+
+```python
+from litellm import embedding
+import os
+
+os.environ["OPENROUTER_API_KEY"] = "your-api-key"
+
+response = embedding(
+ model="openrouter/openai/text-embedding-3-small",

+
+## Image Generation
+
+OpenRouter supports image generation through select models like Google Gemini image generation models. LiteLLM transforms standard image generation requests to OpenRouter's chat completion format.
+
+### Supported Parameters
+
+- `size`: Maps to OpenRouter's `aspect_ratio` format
+ - `1024x1024` → `1:1` (square)
+ - `1536x1024` → `3:2` (landscape)
+ - `1024x1536` → `2:3` (portrait)
+ - `1792x1024` → `16:9` (wide landscape)
+ - `1024x1792` → `9:16` (tall portrait)
+
+- `quality`: Maps to OpenRouter's `image_size` format (Gemini models)
+ - `low` or `standard` → `1K`
+ - `medium` → `2K`
+ - `high` or `hd` → `4K`
+
+- `n`: Number of images to generate
+
+### Usage
+
+```python
+from litellm import image_generation
+import os
+
+os.environ["OPENROUTER_API_KEY"] = "your-api-key"
+
+# Basic image generation
+response = image_generation(
+ model="openrouter/google/gemini-2.5-flash-image",
+ prompt="A beautiful sunset over a calm ocean",
+)
+print(response)
+```
+
+### Advanced Usage with Parameters
+
+```python
+from litellm import image_generation
+import os
+
+os.environ["OPENROUTER_API_KEY"] = "your-api-key"
+
+# Generate high-quality landscape image
+response = image_generation(
+ model="openrouter/google/gemini-2.5-flash-image",
+ prompt="A serene mountain landscape with a lake",
+ size="1536x1024", # Landscape format
+ quality="high", # High quality (4K)
+)
+
+# Access the generated image
+image_data = response.data[0]
+if image_data.b64_json:
+ # Base64 encoded image
+ print(f"Generated base64 image: {image_data.b64_json[:50]}...")
+elif image_data.url:
+ # Image URL
+ print(f"Generated image URL: {image_data.url}")
+```
+
+### Using OpenRouter-Specific Parameters
+
+You can also pass OpenRouter-specific parameters directly using `image_config`:
+
+```python
+from litellm import image_generation
+import os
+
+os.environ["OPENROUTER_API_KEY"] = "your-api-key"
+
+response = image_generation(
+ model="openrouter/google/gemini-2.5-flash-image",
+ prompt="A futuristic cityscape at night",
+ image_config={
+ "aspect_ratio": "16:9", # OpenRouter native format
+ "image_size": "4K" # OpenRouter native format
+ }
+)
+print(response)
+```
+
+### Response Format
+
+The response follows the standard LiteLLM ImageResponse format:
+
+```python
+{
+ "created": 1703658209,
+ "data": [{
+ "b64_json": "iVBORw0KGgoAAAANSUhEUgAA...", # Base64 encoded image
+ "url": None,
+ "revised_prompt": None
+ }],
+ "usage": {
+ "input_tokens": 10,
+ "output_tokens": 1290,
+ "total_tokens": 1300
+ }
+}
+```
+
+### Cost Tracking
+
+OpenRouter provides cost information in the response, which LiteLLM automatically tracks:
+
+```python
+response = image_generation(
+ model="openrouter/google/gemini-2.5-flash-image",
+ prompt="A cute baby sea otter",
+)
+
+# Cost is available in the response metadata
+print(f"Request cost: ${response._hidden_params['additional_headers']['llm_provider-x-litellm-response-cost']}")
+```
