From 96e16f2e0fc29d54169c09719655597764e39830 Mon Sep 17 00:00:00 2001 From: localai-bot <139863280+localai-bot@users.noreply.github.com> Date: Tue, 24 Feb 2026 12:46:37 +0000 Subject: [PATCH 01/20] feat: add automatic conversation compaction based on token threshold This commit adds automatic conversation compaction to prevent context overflow during long-running tool execution sessions. Key changes: - Added LLMUsage struct to track token usage from LLM responses - Modified LLM interface to return token usage alongside Fragment - Added WithCompactionThreshold option to set token count threshold - Added WithCompactionKeepMessages option to configure recent messages to keep - Added compaction logic in ExecuteTools after LLM calls - Added helper functions: compactFragment, checkAndCompact, estimateTokens - Added PromptConversationCompaction for generating conversation summaries - Updated OpenAI and LocalAI clients to return token usage - Updated mock client for testing When compactionThreshold is set (> 0), the conversation will be automatically compacted when estimated token count exceeds the threshold. The compaction generates a summary of the conversation history using an LLM call while preserving recent messages.
