Install the Verbiflow SDK

In a terminal on macOS or Linux. The installer manages Python 3.14:

curl -fsSL https://verbiflow.com/install.sh | sh

It installs, without touching your system Python:

• the verbiflow Python package in an isolated environment at ~/.verbiflow/sdk-venv
• the verbiflow CLI, linked into ~/.local/bin
• the verbiflow agent Skill for Claude Code and Codex, with guidance for finding and using the right functions

~/.verbiflow/sdk-venv/bin/verbiflow --help
~/.verbiflow/sdk-venv/bin/python -c "import verbiflow as vf; print(vf.__version__)"

Both should succeed. If verbiflow isn’t found by name in a new shell, add ~/.local/bin to your PATH.

Restart your agent session so it picks up the Skill, then ask it to log in to Verbiflow. The SDK prints a claim URL — open it in your browser, sign in, and the agent polls the claim status to finish connecting. No tokens to copy around.

import verbiflow as vf

login = vf.auth.login()
print(login["claim_url"])  # open this in your browser

Ask for real work, in plain language:

• “Build a Series A SaaS audience from our funding list, draft copy for heads of GTM, and stage the sequence in Verbiflow.”
• “Take this CSV, enrich it, apply our HubSpot suppression rules, and prepare the rest for review.”

Later, verbiflow update upgrades the SDK and refreshes the Skill in one step.
