What is opencode-history-fulltext-search?

opencode-history-fulltext-search is a plugin for opencode, a terminal based coding tool, that adds full text search over your past session history to its command palette. It lets you search across session titles and the actual content of your messages, and you can choose to search just the current directory or every session you have ever had. The plugin adds two new commands to opencode's command palette. Search history, this dir looks only at sessions tied to the folder you are currently working in, while Search history, anywhere searches across all of your sessions no matter where they happened. As you type, results filter live and the part of the message that matched your search is highlighted and centered so you can see it in context. To keep results useful, the plugin only indexes the actual text and reasoning content of messages. It deliberately skips tool input and output, step markers, patches, and other technical noise, which the author says removes about seventy percent of rows that would otherwise clutter the results. If you pick a session from a different directory while searching everywhere, the plugin does not try to switch you into that session. Instead it copies the exact command you would need to resume it, including the correct directory, to your clipboard, and it automatically detects which clipboard tool your system has available. Under the hood, the plugin reads your local opencode history database directly and only in read only mode, so it will not corrupt your data even while opencode itself might be writing to it. You install it by adding one line to your opencode configuration file, or by running a single CLI command that patches the config for you, and opencode installs the plugin and its dependencies automatically the next time it starts. The author notes this is still an experimental, early stage tool: because it reads a large local database on every search, it may slow opencode down somewhat, and it has not yet been published to a package registry, though you can install it straight from GitHub in the meantime. The project is released under the MIT license.
