Persistent, cross-session memory for Codex, powered by HydraDB.
It recalls relevant notes when you send a prompt, syncs your markdown docs into
HydraDB, and saves conversations as durable memories - the same behavior as the
HydraDB Claude Code plugin, on the same underlying engine (scripts/plugin.mjs).
- Node.js >= 18 and npm
- A HydraDB account (API key + tenant ID) - hydradb.com
- Codex
make bootstrap
export HYDRADB_API_KEY="your-api-key"
export HYDRADB_DATABASE="your-tenant-id"Add a local marketplace entry in your project's .agents/plugins/marketplace.json
pointing at this folder, then enable the plugin in .codex/config.toml. See the
Codex plugin docs for the
current install flow.
Config keys, environment overrides, capture/search/ingest modes, and the slash
commands are identical to the Claude Code plugin - see docs/usage.md
and config.example.json.
