Pick an example, connect your tools, and review the first run.
Set up the API Compatibility Engineer agent template for this project. Follow /SKILL.md for the exact CLI commands.
Goal: Find changes that break representative consumers, reproduce their effects, and deliver coordinated fixes or tested migration requirements as versions evolve.
1. Install the CLI if it is not on PATH, check that I am signed in, and select my team and project.
2. List the first-party workflow templates. If `api-compatibility-engineer` is listed, instantiate it with `--path.slug api-compatibility-engineer` and start the run; otherwise create a project from this template at /new?template=api-compatibility-engineer&preset=trial.
3. Share the run id, follow the run until it finishes, and summarize its outputs and changes.
Ask me before spending FTAI or changing anything outside this repository.
Launch from Claude Code, Codex, Cursor, and other agents.
