Brief
The post lists four tools to improve agent development loops: agent-browser.dev for validating changes in an actual browser, portless.sh to avoid port conflicts and support git worktrees, emulate.dev to emulate third-party APIs during testing, and ai-cli.dev for command-line image and video generation—streamlining verification, integration, and media tasks.
Why it matters
agent-browser.dev — use it to verify agent-made changes in a real browser environment (end-to-end UI verification).
Key details
- portless.sh — provides no port conflicts and is worktree-friendly, simplifying local agent-server workflows.
- emulate.dev and ai-cli.dev — emulate.dev lets agents mimic third-party APIs for testing, while ai-cli.dev enables image and video generation from the CLI.
