OpenCode

Native plugin for OpenCode that hooks the session lifecycle to recall context at prompt time, sync workspace docs, and capture turns.

OpenCode surface	Engine action
`hydradb_recall` tool (agent-invocable)	recall memory/knowledge for a query
`event`: `file.edited`	incremental workspace sync
`event`: `session.idle`	capture the completed turn

Install & set credentials

Add the plugin to your opencode.json; OpenCode installs hydradb-opencode-plugin from npm:

{ "plugin": ["hydradb-opencode-plugin"] }

export HYDRADB_API_KEY="your-api-key"
export HYDRADB_DATABASE="your-database"

Requires Bun (OpenCode’s runtime) and Node.js 18+.

Run with tool approval

Tool calls need approval. Run with --auto or approve hydradb_recall interactively:

opencode run --auto "What did we decide? Use hydradb_recall."

It runs on the same engine as the Claude Code plugin, so the modes and config variables there apply here too.
