Chops: A Local Skill Management Tool for AI Agents

• Platform: macOS
• Keywords: AI, Agent, Skill

@Vanilla: As AI coding tools become more widespread, Skills have emerged as the core mechanism for customizing and extending agent behavior. The problem, however, is that each tool uses its own local storage paths, leaving Skills files scattered across the system with no unified way to manage them—let alone search across tools. Chops is designed to solve this pain point, supporting tools such as Claude Code, Cursor, Codex, Windsurf, Copilot, Aider, and Amp, enabling one-stop Skills management.

First, Chops comes with a built-in editor that allows you to view, edit, and save Skills files directly, eliminating the need to switch to third-party text editors. In addition to Markdown files, Chops can automatically parse YAML frontmatter (metadata) as well as Cursor’s proprietary .mdc format. Notably, Chops also supports creating new Skills and automatically generates standardized templates (boilerplate) for different tools.

Second, Chops supports cross-tool organization, search, and synchronization. It can automatically detect Skills on your machine and display them categorized by tool. You can organize scattered Skills from different AI agents using features like favorites and collections, making them easier to access when needed. If you prefer not to organize them manually, Chops also offers full-text search across Skills files, including names, descriptions, and content. Its indexing is powered by macOS FSEvents, meaning that any changes made to Skills files—whether in the terminal or other editors—are reflected in real time within Chops.

Finally, Chops also supports managing Skills stored on remote servers. Taking OpenClaw as an example, you can connect via server credentials and keys, then use Chops to remotely manage Skills in OpenClaw, including searching, editing, deleting, and installing them.

If you’re simply looking for a dedicated Skills management tool, Chops is already quite feature-complete. For developers who frequently work with multiple AI coding tools, it’s a productivity tool worth integrating into your workflow. Chops is currently free and open-source—you can download it directly from its official website or compile it yourself from GitHub. For now, it is only available on macOS (requires macOS 15 Sequoia or later).

PaperKnife+: An Open-Source, All-in-One Local PDF Toolbox

• Platform: Android
• Keywords: PDF

@大大大K: Most smartphones today support generating PDF scans directly from photos, and we’ve grown accustomed to doing this instead of looking for a scanner. However, that convenience often stops at the first step—if you later need to adjust a specific page, or merge and split multiple PDFs, it becomes difficult without access to a computer. Having a mobile app that can handle PDF files with simple operations would make things much easier.

PaperKnife+ is exactly such a tool. Its UI design is outstanding, with refined details like shadows and icons that feel polished and modern, far from the heavy look of traditional “utility” apps. The feature layout adopts a highly intuitive card-based design, making it both clear and minimal. Although the app does not support Chinese, the English descriptions are simple and easy to understand at a glance. Overall, the experience feels smooth, lightweight, and high-quality.

PaperKnife+ offers powerful PDF editing capabilities that are more than sufficient for everyday use, covering common needs such as merging files, compression, and page rotation. It also includes many advanced features, such as adding watermarks, signatures, encryption, and even metadata editing. If you need to convert PDFs into other formats, PaperKnife+ has you covered—it supports conversion between PDFs and images, packaging files into ZIP archives, and even extracting text from scanned PDFs, with surprisingly good Chinese OCR performance in testing.

Of course, for an app that handles private files, data security is critical. PaperKnife+ is open source, and all processing is done entirely offline, which is central to its design philosophy. The developer aims to ensure users can safely handle sensitive documents such as bills, bank cards, and ID information. If you frequently work with PDFs on your phone, you can download PaperKnife+ from GitHub or IzzyOnDroid—definitely a handy tool to have installed.

brrr: Everything Comes Back to “Notifications”

• Platform: iOS / iPadOS / macOS
• Keywords: Notifications

@Snow: Notifications are an indispensable feature on modern devices. Whether it’s weather updates, calendar reminders, or incoming messages, we’ve grown used to relying on notifications to stay aware of changes. However, even though smartphones can centralize notifications from installed apps and ecosystems can connect notifications across devices, some notifications still remain isolated, and some changes go unnoticed. brrr might help bridge those gaps and give voice to what would otherwise stay silent.

Opening brrr for the first time can be a bit confusing—the home screen only shows a command line. Tap the “Send Test” button in the top right corner, and you’ll receive a push notification saying “Hello world!” on your installed devices, with copy and share options at the bottom. At this point, if you happen to copy the command line into a terminal or open the official documentation, you’ll start to realize what brrr is really capable of.

In terms of design, brrr doesn’t execute tasks or handle trigger logic—it focuses solely on “delivering results.” By tapping the copy button, you’ll get a unique key and a push endpoint. As long as you send content to that endpoint via Webhooks, the message will appear on your devices as a system notification. brrr supports customization of notification titles, subtitles, message content, sounds, grouping, delivery modes, and more. You can even include links and set expiration times. As long as your device or service can send HTTP requests, it can use brrr to deliver messages to you.

Once I understood how brrr works, the first thing that came to mind was syncing notifications from my Synology NAS download tools. All you need to do is go to “DSM → Control Panel → Notification Settings → Webhooks,” create rules for events like download success and failure in tools such as Download Station or qBittorrent, and fill in the push endpoint and content provided by brrr. Then, whenever a download completes or fails, brrr will push the corresponding notification to your devices. If you’re unsure how to structure the JSON payload, the official documentation includes a built-in testing tool where you can fill in fields based on prompts, test the result, and copy it with one click or further customize it.

Similarly, you can integrate brrr with NAS alerts such as backup completion or Docker service failures, as well as other automation workflows, scripts, or devices—like Home Assistant or router setups. As the final step in an automation chain, brrr allows you to stop manually checking various apps or dashboards and instead receive unified notifications only when needed.

You can download brrr from the App Store. It currently supports iPhone, iPad, and Mac, offering a 2-week free trial, after which it is available via subscription at ¥8/month or ¥78/year. Since cross-device and cross-service notification orchestration is still a relatively niche need, it’s best to try it out first and decide whether it fits your workflow before subscribing.

MetaPurge: Don’t Let Your Photos Expose Your Privacy

• Platform: Android
• Keywords: Photo Privacy

@Peggy_: In recent years, reminders about personal privacy have become increasingly common on social media, with one of the most frequent warnings being the risk of privacy leaks when sharing photos. In fact, the everyday images we casually share may contain a significant amount of sensitive information—such as shooting location, date, device name, and more. With the advancement of AI, information that once required manual extraction can now be instantly uncovered.

To better protect our privacy, we can start by processing our images. Common approaches include blurring sensitive content and removing EXIF data. Today’s recommendation, MetaPurge, is a lightweight tool specifically designed for stripping metadata from photos.

Using it is very straightforward. After opening the app, tap to add images on the main screen. Once imported, MetaPurge can read all embedded metadata, which means it can also function as an EXIF viewer to some extent. After selecting the images you want to clean, simply tap “Purge” to remove the data. Thoughtfully, MetaPurge does not overwrite the original files—it allows you to save a clean copy to your gallery instead. This ensures that if you ever need the original image with metadata for organizational purposes, it remains intact.

In addition to processing individual images, MetaPurge also supports batch selection for removing metadata from multiple photos at once. In testing, images processed by MetaPurge were left with almost no metadata—essentially only the file size remained.

It’s also worth noting that MetaPurge does not request network permissions, and all operations are performed locally, so there’s no risk of your data being transmitted or misused.

If you’re looking for a tool like this, you can download MetaPurge from F-Droid. It’s open-source and completely free to use.
