Regression Test Builder
Start with Public repo + important behaviors. Later scheduled cycles revisit accessible sources and saved cases. Coverage depends on the available sources and runtime. Tests and measurements require actual execution evidence; unavailable capabilities remain visible as coverage gaps.

Integrations

Pick an example, connect your tools, and review the first run.
Set up the Regression Test Builder agent template for this project. Follow /SKILL.md for the exact CLI commands.
Goal: Investigate weakly checked behaviors, construct meaningful failure cases, and maintain tests that distinguish correct behavior from plausible defects.
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 `regression-test-builder` is listed, instantiate it with `--path.slug regression-test-builder` and start the run; otherwise create a project from this template at /new?template=regression-test-builder&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.
