From 6b9f9847a5d3e058a07a84f506b51c0b8a8fc546 Mon Sep 17 00:00:00 2001 From: Layne Penney Date: Fri, 23 Jan 2026 07:12:30 -0600 Subject: [PATCH 1/2] feat: implement debug bridge for live session debugging Add a debug bridge feature that streams events to a JSONL file for real-time debugging of Codi sessions. This enables another Claude instance or debugging tool to observe session activity. Features: - --debug-bridge CLI flag to enable event streaming - Events written to ~/.codi/debug/events.jsonl - Session metadata in ~/.codi/debug/session.json - Event types: session_start, session_end, user_input, tool_call_start, tool_call_end, tool_result, api_request, api_response, context_compaction, error, model_switch - Auto-truncation of long inputs/outputs to keep events manageable - Proper shutdown handling on /exit and SIGTERM/SIGINT Usage: codi --debug-bridge # or CODI_DEBUG_BRIDGE=true codi Co-Authored-By: Claude Opus 4.5 --- src/agent.ts | 62 ++++++ src/debug-bridge.ts | 425 +++++++++++++++++++++++++++++++++++++ src/index.ts | 28 +++ tests/debug-bridge.test.ts | 282 ++++++++++++++++++++++++ 4 files changed, 797 insertions(+) create mode 100644 src/debug-bridge.ts create mode 100644 tests/debug-bridge.test.ts diff --git a/src/agent.ts b/src/agent.ts index 1a8ed90..dfbe341 100644 --- a/src/agent.ts +++ b/src/agent.ts @@ -44,6 +44,7 @@ import { } from './utils/index.js'; import { logger, LogLevel } from './logger.js'; import type { AuditLogger } from './audit.js'; +import { getDebugBridge, isDebugBridgeEnabled } from './debug-bridge.js'; import { checkCommandApproval, getApprovalSuggestions, @@ -539,14 +540,27 @@ ${contextToSummarize}`, ); this.conversationSummary = summaryResponse.content; + const messagesBefore = this.messages.length; this.messages = applySelection(this.messages, selection); const newTokens = countMessageTokens(this.messages); logger.debug(`Compacted to ${newTokens} tokens.

Tests now conditionally check behavior based on whether global config exists.
