devvit-logs_skill

Overview

This skill streams Devvit logs for an installed app on a specified subreddit to help with quick debugging. It wraps the devvit CLI logs command, captures the first burst of output, and auto-exits after a short window to avoid long-running streaming sessions. Provide the target subreddit and optional app name or --since flag to control the capture window.

How this skill works

The skill asks for the target subreddit (required) and optionally accepts an app name and --since=... duration. It runs the devvit logs command, captures stdout/stderr, and listens for output. The run stops automatically after the first burst of logs or 5 seconds, whichever comes first, and returns a short summary and the raw output captured.

When to use it

• You need a quick snapshot of an app’s recent logs without an open streaming session.
• Debugging an installed Devvit app after triggering an action in a subreddit.
• Confirm whether the app is producing logs after a deploy or configuration change.
• Capture historical logs with a --since flag to inspect prior activity.
• When you want an automated short capture to avoid hanging the CLI during interactive sessions.

Best practices

• Always provide the subreddit name; the skill will prompt if omitted.
• Use --since=30m or --since=1h to include recent historical logs when live traffic is low.
• Specify the app name if the app code lives in another folder or differs from the default.
• Trigger a known action in the app just before running the skill to ensure output is generated.
• If no logs appear, retry with a longer --since window or verify devvit CLI access and permissions.

Example use cases

• Quickly check logs after deploying a change to my-app on r/my-subreddit.
• Run a five-second capture to confirm an action handler executed during a manual test.
• Fetch recent logs from r/example-subreddit using --since=1h to investigate an intermittent error.
• Verify that the app is installed and has logging access when troubleshooting permission issues.
• Capture a short log snippet to paste into a bug report or chat with teammates.
