fizzy is a command-line interface for Fizzy. Manage boards, cards, comments, and more from your terminal or through AI agents.

• Works standalone or with any AI agent (Claude, Codex, Copilot, Gemini)
• JSON output with breadcrumbs for easy navigation
• Token authentication via personal access tokens
• Includes agent skill and Claude plugin setup

Quick Start

curl -fsSL https://raw.githubusercontent.com/basecamp/fizzy-cli/master/scripts/install.sh | bash
fizzy setup

That's it. The installer detects your platform and architecture, downloads the right binary, and verifies checksums. The setup wizard then walks you through configuring your token, selecting your account, and optionally setting a default board.

Recommended first checks:

fizzy doctor
fizzy board list

Use fizzy doctor any time you want a full health check of your install, config, auth, API connectivity, board context, and agent setup.

yay -S fizzy-cli

brew install robzolkos/fizzy-cli/fizzy-cli

scoop bucket add basecamp https://github.com/basecamp/homebrew-tap
scoop install fizzy

go install github.com/basecamp/fizzy-cli/cmd/fizzy@latest

curl -LO https://github.com/basecamp/fizzy-cli/releases/latest/download/fizzy-cli_VERSION_linux_amd64.deb
sudo dpkg -i fizzy-cli_VERSION_linux_amd64.deb

curl -LO https://github.com/basecamp/fizzy-cli/releases/latest/download/fizzy-cli_VERSION_linux_amd64.rpm
sudo rpm -i fizzy-cli_VERSION_linux_amd64.rpm

Next Steps

Start with a few common commands:

fizzy board list
fizzy card list
fizzy card show 42
fizzy search "authentication"
fizzy comment create --card 42 --body "Looks good!"

Then branch out as needed:

fizzy board accesses --board ID           # Show board access settings and users
fizzy activity list --board ID            # List recent board activity
fizzy webhook deliveries --board ID WEBHOOK_ID
fizzy user export-create USER_ID

For the full command surface, run fizzy commands --json or read skills/fizzy/SKILL.md.

Attachments

Simple mode uses repeatable --attach and appends inline attachments to the end of card descriptions or comment bodies:

fizzy card create --board ID --title "Bug report" --description "See attached" --attach screenshot.png
fizzy comment create --card 42 --attach logs.txt
fizzy comment create --card 42 --body_file comment.md --attach screenshot.png --attach trace.txt

Advanced mode still works when exact placement matters:

SGID=$(fizzy upload file screenshot.png --jq '.data.attachable_sgid')
fizzy card create --board ID --title "Bug report" \
  --description "<p>See screenshot</p><action-text-attachment sgid=\"$SGID\"></action-text-attachment>"

Use signed_id from fizzy upload file only for card header images via --image.
