Upgrading Pegasus

Instructions

This skill helps users upgrade their SaaS Pegasus codebase.

Use the pegasus-cli to trigger the upgrade. It can be called via the pegasus command in the project's python environment.

You first need to list the user's project and find the right one.

pegasus projects list

You should be able to compare the project names to what's defined pegasus-config.yaml to find the right id.

You may need to prompt the user to authenticate first. If necessary, do that via the CLI (pegasus auth).

Before pushing

  1. Ensure main is up to date: Run git checkout main && git pull before starting the upgrade. The merge will be against main, so it must have the latest changes.

Pushing

Use the CLI flags to avoid interactive prompts:

# Upgrade to latest stable version (non-interactive):
pegasus projects push <project_id> --upgrade

# Upgrade to latest dev version (non-interactive):
pegasus projects push <project_id> --dev

Important: Always pass --upgrade or --dev to avoid interactive prompts that require stdin. Without these flags, the CLI will show an interactive menu that doesn't work well in non-interactive environments.

If the user doesn't specify stable vs dev, default to --upgrade (stable).

After the push completes

  1. Run git fetch origin to see the new branch
  2. The branch name will be in the format pegasus-<version>-<timestamp> (e.g. pegasus-2026.2.1.3-1771252378.779356)
  3. git checkout <branch-name> to switch to it (it will already be up to date from the push)
  4. Merge the user's default branch (usually main) into the upgrade branch using your "resolve pegasus conflicts" skill
