Request Preparation (New Phase) + +Before sending to OpenRouter, usage happens in `proxy-server.ts`: + +```typescript +// 1. Get adapter +const adapter = adapterManager.getAdapter(); + +// 2. Prepare request (translate thinking params) +adapter.prepareRequest(openrouterPayload, claudeRequest); + +// 3. Send to OpenRouter +``` + +This phase allows adapters to: +- Map `thinking.budget_tokens` to model-specific fields +- Enable specific flags (e.g., `enable_thinking`) +- Remove unsupported parameters to prevent API errors + +### 2. Adapter Selection + +The `AdapterManager` selects the right adapter based on model ID: + +```typescript +const adapterManager = new AdapterManager("x-ai/grok-code-fast-1"); +const adapter = adapterManager.getAdapter(); +// Returns: GrokAdapter + +const adapterManager2 = new AdapterManager("openai/gpt-4"); +const adapter2 = adapterManager2.getAdapter(); +// Returns: DefaultAdapter (no transformation) +``` + +### 3. Integration in Proxy Server + +In `proxy-server.ts`, the adapter processes each text chunk: + +```typescript +// Create adapter +const adapterManager = new AdapterManager(model || ""); +const adapter = adapterManager.getAdapter(); +let accumulatedText = ""; + +// Process streaming content +if (textContent) { + accumulatedText += textContent; + const result = adapter.processTextContent(textContent, accumulatedText); + + // Send extracted tool calls + for (const toolCall of result.extractedToolCalls) { + sendSSE("content_block_start", { + type: "tool_use", + id: toolCall.id, + name: toolCall.name + }); + // ... send arguments, close block + } + + // Send cleaned text + if (result.cleanedText) { + sendSSE("content_block_delta", { + type: "text_delta", + text: result.cleanedText + }); + } +} +``` + +--- + +## šŸŽÆ Grok Adapter Deep Dive + +### The Problem + +Grok models output function calls in xAI's XML format: + +```xml + + /path/to/file + +``` + +Instead of OpenAI's JSON format: + +```json +{ + "tool_calls": [{ + "id": "call_123", + "type": "function", + "function": { + "name": "Read", + "arguments": "{\"file_path\":\"/path/to/file\"}" + } + }] +} +``` + +### The Solution + +`GrokAdapter` parses the XML and translates it: + +```typescript +export class GrokAdapter extends BaseModelAdapter { + private xmlBuffer: string = ""; + + processTextContent(textContent: string, accumulatedText: string): AdapterResult { + // Accumulate text to handle XML split across chunks + this.xmlBuffer += textContent; + + // Pattern to match complete xAI function calls + const xmlPattern = /(.*?)<\/xai:function_call>/gs; + const matches = [...this.xmlBuffer.matchAll(xmlPattern)]; + + if (matches.length === 0) { + // Check for partial XML + if (this.xmlBuffer.includes(" ({ + id: `grok_${Date.now()}_${Math.random().toString(36).substr(2, 9)}`, + name: match[1], + arguments: this.parseXmlParameters(match[2]) + })); + + // Remove XML from text + let cleanedText = this.xmlBuffer; + for (const match of matches) { + cleanedText = cleanedText.replace(match[0], ""); + } + + this.xmlBuffer = ""; + return { cleanedText: cleanedText.trim(), extractedToolCalls: toolCalls, wasTransformed: true }; + } + + shouldHandle(modelId: string): boolean { + return modelId.includes("grok") || modelId.includes("x-ai/"); + } +} +``` + +### Key Features + +1. **Multi-Chunk Handling**: Buffers partial XML across streaming chunks +2. **Parameter Parsing**: Extracts `` tags and converts to JSON +3. **Smart Type Detection**: Tries to parse values as JSON (for numbers, objects, arrays) +4. **Text Preservation**: Keeps non-XML text and sends it normally + +--- + +## šŸ§Ŗ Testing + +### Unit Tests (tests/grok-adapter.test.ts) + +Validates XML parsing logic: + +```typescript +test("should detect and parse simple xAI function call", () => { + const adapter = new GrokAdapter("x-ai/grok-code-fast-1"); + const xml = '/test.txt'; + + const result = adapter.processTextContent(xml, xml); + + expect(result.wasTransformed).toBe(true); + expect(result.extractedToolCalls).toHaveLength(1); + expect(result.extractedToolCalls[0].name).toBe("Read"); + expect(result.extractedToolCalls[0].arguments.file_path).toBe("/test.txt"); +}); +``` + +**Test Coverage:** +- āœ… Simple function calls +- āœ… Multiple parameters +- āœ… Text before/after XML +- āœ… Multiple function calls +- āœ… Partial XML (multi-chunk) +- āœ… Normal text (no XML) +- āœ… JSON parameter values +- āœ… Model detection +- āœ… Buffer reset + +### Integration Tests (tests/grok-tool-format.test.ts) + +Validates system message workaround (attempted fix): + +```typescript +test("should inject system message for Grok models with tools", async () => { + // Validates that we try to force OpenAI format + expect(firstMessage.role).toBe("system"); + expect(firstMessage.content).toContain("OpenAI tool_calls format"); + expect(firstMessage.content).toContain("NEVER use XML format"); +}); +``` + +**Note:** System message workaround **FAILED** - Grok ignores instruction.

Qwen Adapter (`QwenAdapter`) +- **File:** `src/adapters/qwen-adapter.ts` +- **Behavior:** + - Enables the specific `enable_thinking` flag required by Alibaba Cloud / OpenRouter. + - Passes the budget through directly. + +### 5.

Status Line Script Generation +- Creates a complex bash script that: + - Reads token data from temp file + - Calculates context percentage + - Formats output with ANSI colors + - All embedded in JSON settings file! + +### 5. API Key Handling Strategy +- OpenRouter mode: Sets placeholder `ANTHROPIC_API_KEY` to prevent Claude dialog +- Monitor mode: Deletes `ANTHROPIC_API_KEY` to allow Claude to use native auth +- Both: Actually uses the key specified in the proxy or from Claude's request + +## Integration Points + +### With Claude Code +1. **Temporary Settings File** - Passed via `--settings` flag +2. **Environment Variables** - `ANTHROPIC_BASE_URL`, `CLAUDISH_ACTIVE_MODEL_NAME`, `ANTHROPIC_API_KEY` +3. **Proxy Server** - Running on localhost, acts as Anthropic API +4. **Token File** - Status line reads from `/tmp/claudish-tokens-{PORT}.json` + +### With OpenRouter +1. **API Requests** - Proxy transforms Anthropic ā†’ OpenRouter format +2. **Authentication** - Uses `OPENROUTER_API_KEY` environment variable +3. **Model Selection** - Any OpenRouter model ID is supported + +## Recommendations for Environment Variable Support + +Based on this analysis, here are recommendations for adding proper environment variable support: + +### 1. Add Model Display Name Support +```typescript +// In config.ts +export const ENV = { + // ... existing + ANTHROPIC_MODEL: "ANTHROPIC_MODEL", // Display name override + CLAUDISH_MODEL_DISPLAY_NAME: "CLAUDISH_MODEL_DISPLAY_NAME", // Custom display name +}; +``` + +### 2. Modify claude-runner.ts +```typescript +// Extract display name from config +const displayName = config.modelDisplayName || config.model; + +// Pass to status line command via environment variable +env[ENV.CLAUDISH_MODEL_DISPLAY_NAME] = displayName; +``` + +### 3. Update Status Line Script +```bash +# Instead of: +printf "... ${YELLOW}%s${RESET} ..." "$CLAUDISH_ACTIVE_MODEL_NAME" + +# Could support: +DISPLAY_NAME=${CLAUDISH_MODEL_DISPLAY_NAME:-$CLAUDISH_ACTIVE_MODEL_NAME} +printf "... ${YELLOW}%s${RESET} ..." "$DISPLAY_NAME" +``` + +### 4. Support ANTHROPIC_MODEL Variable +```typescript +// In cli.ts, after parsing CLAUDISH_MODEL +const envModel = process.env[ENV.CLAUDISH_MODEL]; +const anthropicModel = process.env[ENV.ANTHROPIC_MODEL]; +if (!config.model) { + config.model = anthropicModel || envModel; +} +``` + +## Summary + +Claudish is a well-structured CLI tool that: +- āœ… Manages model selection through multiple channels (flags, env vars, interactive prompts) +- āœ… Communicates active model to Claude Code via `CLAUDISH_ACTIVE_MODEL_NAME` environment variable +- āœ… Tracks tokens in a file for status line consumption +- āœ… Uses temporary settings files to avoid modifying global configuration +- āœ… Has clear separation of concerns between CLI, proxy, and runner components + +**Current environment variable handling is functional but could be enhanced with:** +- Support for `ANTHROPIC_MODEL` for consistency with Claude Code +- Custom display names for models +- More flexible model identification system + +The token file mechanism at `/tmp/claudish-tokens-{PORT}.json` is clever and allows the status line to display real-time token usage without modifying the proxy or Claude Code itself. diff --git a/ai_docs/claudish-EXPLORATION_INDEX.md b/ai_docs/claudish-EXPLORATION_INDEX.md new file mode 100644 index 0000000..a5a9971 --- /dev/null +++ b/ai_docs/claudish-EXPLORATION_INDEX.md @@ -0,0 +1,242 @@ +# Claudish Codebase Exploration - Complete Index + +## Overview + +This directory contains comprehensive analysis of the Claudish codebase, created November 15, 2025.
