From 24a3253347c25489a1eaef2e0fbd29747af1f66e Mon Sep 17 00:00:00 2001 From: Claude Date: Mon, 17 Nov 2025 16:52:29 -0500 Subject: [PATCH 1/5] Add local inference service with summarize command MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Adds local GGUF model inference using llama.cpp via yzma for task summarization and branch name generation. Key components: - InferenceService: Handles model loading and text generation - ModelDownloader: Downloads and caches GGUF models from HuggingFace - LibraryDownloader: Auto-downloads llama.cpp libraries for current platform - summarize command: CLI interface for generating summaries - download command: Pre-download model and libraries - REST API endpoint: POST /v1/inference/summarize Critical fix: Must use addSpecial=true when tokenizing prompts for Gemma models to include BOS token - without this, the model produces incorrect outputs (was outputting examples from the prompt instead of actual summaries). 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- .gitignore | 6 + container/.goreleaser.yml | 22 ++ container/docs/docs.go | 134
