context-attachment-manager vs context-harness

context-attachment-manager: Context Attachment Manager is a plugin for Codex and Claude Desktop that allows users to selectively send past images to the LLM, preventing context overload and improving conversational performance. It enables granular control over visual context, ensuring efficient interaction in long, image-heavy discussions.; context-harness: Context Harness is a local-first framework designed for ingesting and retrieving external knowledge into an AI tool's context. It supports various data sources like files, Git repositories, and S3 buckets, storing them in a local SQLite database for efficient keyword and semantic search.
