plastic-labs Honcho Setup
Walk the user through first-time Honcho configuration so persistent memory works in Cursor.
Steps
1. Check current state
Run this command to check if HONCHO_API_KEY is already set:
echo "${HONCHO_API_KEY:+set}"
If the output is set, skip to step 3 (validation). Otherwise continue.
2. Direct user to get an API key
Tell the user:
You need a Honcho API key. Get one for free at https://app.honcho.dev
Once you have it, add this line to your shell config (
~/.zshrcor~/.bashrc):export HONCHO_API_KEY="your-key-here"Then restart Cursor so it picks up the new environment variable.
Wait for the user to confirm they have set the key. If they paste the key directly in chat, warn them not to share API keys in conversation and remind them to set it as an environment variable instead.
3. Validate the API key
Test the connection by running the setup runner. Find the plugin directory first:
HONCHO_PLUGIN="${HONCHO_PLUGIN_DIR:-$HOME/.honcho/plugins/cursor-honcho/plugins/honcho}"
bun run "$HONCHO_PLUGIN/src/skills/setup-runner.ts"
If it succeeds, the key is valid and the config file has been created.
If it fails, help the user troubleshoot:
- Key not set: re-check shell config and restart Cursor
- Authentication error: key may be invalid, get a new one from https://app.honcho.dev
- Network error: check internet connection
- Plugin not found: check that cursor-honcho is installed at
~/.honcho/plugins/cursor-honcho
4. Confirm setup
Tell the user that Honcho is configured and memory will be active on their next session. Suggest they restart Cursor or open a new chat to see the memory context load.
