Use Structured Messages +❌ **Bad:** `Session ${session.id}: ${existingMessages.length} existing messages` +✅ **Good:** `"Session message context loaded"` with context `{ sessionId, existingMessageCount, isNewSession }` + +**Why:** Structured messages are parseable by log analysis tools and easier to search. + +### 2. Keep Messages Action-Oriented +❌ **Bad:** `"handleGetMcpStatus error"` +✅ **Good:** `"Failed to get MCP server status"` + +**Why:** Action-oriented messages clearly describe what happened or what failed. + +### 3. Move Dynamic Data to Context +❌ **Bad:** `log.error("Failed to read file ${filePath}", { filePath })` +✅ **Good:** `log.error("Failed to read attached file", { filePath, error })` + +**Why:** Keeps message format consistent and makes logs easier to parse. + +### 4. Use Appropriate Log Levels +- **error**: Operation failed and functionality is broken +- **warn**: Potential issue but operation continues (fallbacks, retries) +- **info**: Normal operation milestones and state changes +- **debug**: Detailed diagnostic information for troubleshooting + +### 5. Include Relevant Context +Always include relevant identifiers and metadata: +```typescript +log.error("Failed to abort active request", { + sessionId: resolvedSessionId, + error: error instanceof Error ? error.message : String(error), +}, error as Error); +``` + +### 6. Use Feature Flow Tracking +For multi-step operations, use feature flow tracking: +```typescript +const flow = log.startFeatureFlow('DataImport', { source: 'api' }); +log.featureStep(flow, 'validation', { valid: 95, invalid: 5 }); +log.endFeatureFlow(flow, { success: true, imported: 95 }); +``` + +## Message Format Patterns + +### Error Messages +**Pattern:** `"Failed to "` +```typescript +log.error("Failed to read attached image", { + filePath: uri.fsPath, + error: error.message, +}, error); +``` + +### Warning Messages +**Pattern:** `" failed, "` or `"Failed to , "` +```typescript +log.warn("SDK file search failed, using VS Code fallback", { + query, + error: error.message, +}); +``` + +### Info Messages +**Pattern:** `" past tense>"` or `" "` +```typescript +log.info("MCP server status sent to webview", { + serverCount: Object.keys(servers).length, + toolCount: toolIds.length, +}); +``` + +### Debug Messages +**Pattern:** `" "` or `" completed"` +```typescript +log.debug("Session message context loaded", { + sessionId: session.id, + existingMessageCount: existingMessages.length, + isNewSession, +}); +``` + +## Context Object Guidelines + +### Always Include +- **Identifiers**: `sessionId`, `filePath`, `messageId`, `correlationId` +- **Error details**: `error: error.message` (if Error object) +- **Counts/quantities**: `count`, `duration`, `size` + +### Naming Convention +Use **camelCase** for context keys: +```typescript +✅ { sessionId, existingMessageCount, isNewSession } +❌ { session_id, existing_message_count, is_new_session } +``` + +### Derived Data +Calculate and include relevant derived values: +```typescript +log.debug("AI response received", { + sessionId: session.id, + durationSeconds: duration, // Calculated value + hasData: Boolean(responseData), + status: response.response?.status, +}); +``` + +## Error Handling Patterns + +### With Error Object +```typescript +} catch (error) { + log.error("Failed to read attached file", { + filePath, + error: error instanceof Error ? error.message : String(error), + }, error as Error); +} +``` + +### Without Error Object +```typescript +} catch (error) { + log.error("Failed to abort active request", { + sessionId: resolvedSessionId, + error: error instanceof Error ? error.message : String(error), + }, error as Error); +} +``` + +## Feature Flow Examples + +### Simple Flow +```typescript +const flow = log.startFeatureFlow('FileSearch', { query }); +try { + const results = await searchFiles(query); + log.endFeatureFlow(flow, { + result: 'completed', + resultCount: results.length + }); +} catch (error) { + log.endFeatureFlow(flow, { + result: 'failed', + error: String(error) + }); +} +``` + +### Multi-Step Flow +```typescript +const flow = log.startFeatureFlow('DataImport', { source: 'api' }); +log.featureStep(flow, 'validation', { valid: 95, invalid: 5 }); +log.featureStep(flow, 'transformation', { transformed: 95 }); +log.featureStep(flow, 'loading', { loaded: 95 }); +log.endFeatureFlow(flow, { success: true, imported: 95 }); +``` + +## Searchable Logs + +Good logs make it easy to: +1. **Find errors:** Search for "Failed" or "error" level +2. **Track sessions:** Search for specific `sessionId` +3. **Measure performance:** Search for "duration" or "performance" +4. **Debug features:** Search for feature names in feature flows + +## Console Output Examples + +### Pretty Mode (default) +``` +[14:23:45.123] ❌ [ERROR] [ChatView] Failed to read attached file {"filePath":"src/app.ts","error":"ENOENT"} +[14:23:45.456] ⚠️ [WARN] [ChatView] SDK file search failed, using VS Code fallback {"query":"test"} +[14:23:46.789] ℹ️ [INFO] [ChatView] MCP server status sent to webview {"serverCount":3,"toolCount":15} +[14:23:47.012] 🔍 [DEBUG] [ChatView] Session message context loaded {"sessionId":"abc-123","existingMessageCount":42} +``` + +### JSON Mode +```json +{"timestamp":"2026-06-07T14:23:45.123Z","level":"error","category":"ChatView","message":"Failed to read attached file","context":{"filePath":"src/app.ts","error":"ENOENT"}} +``` + +## Common Mistakes to Avoid + +1. **Embedding data in messages:** Don't use template strings for dynamic values +2. **Vague messages:** Avoid "error occurred" or "failed" without context +3. **Missing identifiers:** Always include relevant IDs (sessionId, filePath, etc.) +4. **Inconsistent naming:** Use the same terminology across logs +5. **Wrong log levels:** Don't use `error` for recoverable issues + +## Testing Your Logs + +1. **Enable JSON mode** and verify logs parse correctly +2. **Search for specific patterns** to ensure they're found +3. **Check console output** in both pretty and hybrid modes +4. **Verify error context** includes all relevant information diff --git a/package.json b/package.json index d75e9b9..12adc56 100644 --- a/package.json +++ b/package.json @@ -236,15 +236,15 @@ "maximum": 0.99, "description": "Fraction of model context limit at which auto-compaction fires (0.9 = 90%)" }, - "opencode.requestTimeout": { - "type": "number", - "default": 120000, - "minimum": 10000, - "maximum": 600000, - "description": "Request timeout in milliseconds for API calls (default: 120s, min: 10s, max: 10min)", - "scope": "window", - "order": 10 - }, + "opencode.requestTimeout": { + "type": "number", + "default": 60000, + "minimum": 10000, + "maximum": 600000, + "description": "Request timeout in milliseconds for API calls (default: 60s, min: 10s, max: 10min)", + "scope": "window", + "order": 10 + }, "opencode.complexQueryMultiplier": { "type": "number", "default": 1.5, @@ -262,15 +262,15 @@ } } }, - "scripts": { - "build": "npm run structured-output:sync && npm run webview:build && npm run compile", - "verify": "npm run structured-output:check && npm run build && npm run lint && npm test", + "scripts": { + "build": "npm run webview:build && npm run compile", + "verify": "npm run build && npm run lint && npm test", "vscode:prepublish": "npm run build", "compile": "node esbuild.config.cjs", "watch": "node esbuild.config.cjs --watch", "dev": "node scripts/dev-simple.mjs", "dev:full": "node scripts/dev-hotreload.mjs", - "webview:build": "npm run structured-output:sync && npm --prefix webview/shared run build", + "webview:build": "npm --prefix webview/shared run build", "webview:watch": "npm --prefix webview/shared run build -- --watch", "structured-output:sync": "node scripts/sync-structured-output-contract.mjs", "structured-output:check": "node scripts/sync-structured-output-contract.mjs --check", diff --git a/scripts/sync-structured-output-contract.mjs b/scripts/sync-structured-output-contract.mjs index 31691ec..ca12d8f 100644 --- a/scripts/sync-structured-output-contract.mjs +++ b/scripts/sync-structured-output-contract.mjs @@ -46,6 +46,24 @@ const targets = [ "structuredOutputValidator.ts", ), }, + { + source: path.join( + repoRoot, + "src", + "shared", + "centralizedDebugPayloadFilter.ts", + ), + dest: path.join( + repoRoot, + "webview", + "shared", + "src", + "chat", + "lib", + "generated", + "centralizedDebugPayloadFilter.ts", + ), + }, ];

WebView Lifecycle: + * - Creates and initializes the webview + * - Sets up message handlers + * - Manages webview options (scripts, local resources) + * + * 2. Message Handling: + * - Receives messages from webview + * - Dispatches to appropriate handler methods + * - Sends responses back to webview + * + * 3. Streaming Integration: + * - Subscribes to MessageStreamService for real-time updates + * - Forwards stream events to webview + * - Handles stream completion and errors + * + * 4. Plan Detection: + * - Analyzes AI responses for implementation plans + * - Auto-saves detected plans to workspace + * - Notifies user and provides plan viewing option + * + * 5. Queue Management: + * - Maintains prompt queue for batch execution + * - Executes prompts sequentially + * - Manages execution state + * + * 6.
