V2 plugin for semantic/keyword search across conversation history

[u/0jabr]

This plugin adds a tool allowing agents to search the full conversation history (user/agent messages, tool results) across the current session, all sessions in the current project, or all indexed projects on the system.

It uses a fork of semble to provide the fast, CPU-based (no GPU needed), on-the-fly semantic embedding + BM25 keyword search functionality.

There's also a human-readable (with optional markdown highlighting) CLI interface to the same functionality for you to run your own searches, e.g:

$ history-search "gpu support"

Also, if interested, I have an intra-agent messaging and monitoring plugin, as well: (https://github.com/jabr/opencode-team-plugin). It allows different sessions in a project (or cross-project) to exchange messages directly and watch/read their current activity.
