aws-cli
Universal Command Line Interface for Amazon Web Services
The AWS CLI is the universal command-line interface for managing AWS services, automating tasks, and scripting cloud workflows. It exposes nearly every public API from EC2 and S3 to IAM, Lambda, and beyond, providing parity with the service SDKs in a tool you can run anywhere. Profiles, regions, single-sign-on, and credential helpers make it straightforward to switch contexts securely across accounts and environments. Its output controls and JMESPath querying let you slice, filter, and transform JSON responses directly in the shell, which is essential for automation. Waiters, paginators, and retries handle long-running or large list operations cleanly so scripts are resilient. The CLI’s stability and extensive documentation make it a cornerstone for CI/CD, incident response, and day-to-day operations. -

jdbc2csv.jar
Command-line sql JDBC tool
jdbc2csv is a small command-line tool written in JAVA and can be used on all platforms, for which JRE 8 or higher is available. To connect to a specific DBMS the tool uses its JDBC driver. The result of the executed 'select' query is displayed in CSV format ( different standards are supported ). When there is an error the tool stops with exit code 1 and the error message is output on stderr. jdbc2csv is created with a main purpose to be used in shell-scripts. Relatively easy to configurate, this tool is suitable for queries ‘select’, ‘update’ and ‘delete’. I think that is not suitable for a large number of requests, like 'insert'. -

GeoIP
This project automatically generates GeoIP files in multiple formats
GeoIP is a community-maintained project that generates and publishes enhanced GeoIP/Geo-database and IP-location/routing data in multiple formats (e.g. V2Ray .dat, MaxMind .mmdb, and others) to support proxy, VPN, or routing tools requiring IP-to-country/region resolution. Rather than depending solely on the official GeoLite2 data, geoip augments and merges data sources (especially for certain regions) to improve coverage or tailor by use-case (e.g. proxy-specific rules, private networks, or region-based classification). The repo provides automated, periodic releases (e.g. weekly or on schedule) and also offers a CLI tool so users can regenerate or customize geo data in the format they need — for example, producing a .dat file for V2Ray / Xray-core, or a MaxMind-compatible .mmdb. -

Gitlab CLI
Ruby wrapper and CLI for the GitLab REST API
Gitlab CLI is a Ruby gem and CLI tool that wraps the REST API of GitLab (including self-hosted GitLab instances) to make automation, scripting and integration simpler. It provides a Ruby DSL that abstracts away direct HTTP calls, letting developers interact with GitLab’s API in idiomatic Ruby (creating projects, merge requests, listing users, etc.). In addition to the Ruby library, there is a command-line interface which enables many GitLab operations from the terminal (or scripts) without needing to manually craft API requests. The gem supports customization of endpoint URL, private tokens, proxy and HTTP options, making it suitable for self-managed GitLab instances as well as gitlab.com. It is test-covered and built to be simple to integrate into Ruby projects or CI scripts. Being open-source under a BSD-2-Clause license, it invites reuse in organizational tooling or internal DevOps workflows. Overall, it is a useful tool for teams working with GitLab who want to automate tasks. -

Obsidian Skills
Agent skills for Obsidian
Obsidian-Skills is a repository of agent skills tailored for use with Obsidian and any Claude-compatible agent that follows the standard Agent Skills specification, enabling AI assistants to better understand and interact with Obsidian content. These skills are markdown-driven specifications that teach Claude Code (or similar agents) how to perform context-aware tasks within Obsidian’s unique environment, such as interpreting different file types and workflows, automating workflows tied to notes, or enhancing agent responses with structured knowledge. By providing formal descriptions of patterns, conventions, and workflows common to Obsidian users, the skills empower AI tools to give more relevant suggestions, generate content that adheres to user conventions, or execute complex multi-step operations that respect the knowledge graph and file relationships. -

skills
The open agent skills tool - npx skills
skills is a CLI that turns “agent skills” into a portable, installable ecosystem, letting developers add reusable instruction sets to many different coding agents from a single command. Instead of hardcoding prompts per tool, it standardizes skills as SKILL.md files with structured metadata so they can be discovered, listed, installed, updated, and version-tracked consistently. The CLI supports pulling skills from common git sources, including GitHub shorthand, full URLs, direct paths inside repos, GitLab URLs, generic git remotes, and even local folders. It is designed to work across a wide range of agents and editors, so one skill package can be installed into multiple agent-specific directories without rewriting anything for each environment. It also supports both interactive and automation-friendly flows, including non-interactive installs for CI and bulk installs for all skills, which makes it usable for teams that want consistent agent capability across machines. -

ClawHub
Skill Directory for OpenClaw
ClawHub is a public skill registry and ecosystem component for the OpenClaw AI assistant platform, designed to host, publish, version, and search text-based agent skill packages (each typically containing a SKILL.md plus metadata) that extend the capabilities of agents. As a centralized browsing and storage platform, ClawHub lets developers and contributors explore a catalog of reusable skills with supporting tags, changelogs, moderation controls, and vector search powered by embeddings instead of brittle keyword matching. Users can publish new skill versions, search for relevant abilities to add to their own OpenClaw agents, and view rendered skill documentation directly within the web interface or via a CLI-friendly API. It also supports a parallel “SOUL.md” registry for publishing narrative or lore content associated with skill collections, enabling richer context for skill authorship. -

MCPorter
Call MCPs via TypeScript, masquerading as simple TypeScript API
Mcporter is a utility designed to port Minecraft worlds from Java Edition to Bedrock Edition while preserving as much structural and gameplay integrity as possible. It addresses the complex differences between the two editions’ world formats, block states, biomes, and entity representations, giving players a seamless way to bring beloved Java worlds into the Bedrock ecosystem. The tool analyzes and converts chunks, block definitions, and metadata to a format Bedrock can interpret, ensuring terrain, constructions, and most in-game elements remain recognizable and playable after conversion. Its command-line workflow simplifies what would otherwise be a manual and error-prone process, allowing users to specify source worlds, conversion settings, and target outputs with clarity and control. -

QMD
mini cli search engine for your docs, knowledge bases, etc.
QMD is a powerful and lightweight command-line tool that acts as an on-device search engine for your personal knowledge base, allowing you to index and search files like Markdown notes, meeting transcripts, technical documentation, and other text collections without depending on cloud services. Designed to keep all search activity local, it combines classic full-text search techniques with modern semantic features such as vector similarity and hybrid ranking so that queries return not just literal matches but conceptually relevant results. Users can organize content into named collections, embed documents for semantic retrieval, and then perform keyword searches, semantic searches, or hybrid natural-language queries to quickly surface the most useful information across all indexed sources. Because the entire system runs on the user’s machine, privacy is preserved and there’s no risk of exposing sensitive content to outside providers. -

shot-scraper
A command-line utility for taking automated screenshots of websites
shot-scraper is a command-line utility for taking automated screenshots of web pages using a headless browser engine. After installation, a single command can capture a full-page screenshot of a URL and save it to a file, making it ideal for documentation, monitoring, and visual regression tasks. Under the hood it uses a modern browser (installed via a one-time shot-scraper install step) and exposes options for viewport size, full-page versus clipped screenshots, and device emulation. Beyond simple captures, it can run custom JavaScript before taking the shot, allowing you to open menus, scroll, or manipulate the DOM so the screenshot reflects the desired state. The project is deeply integrated with automation workflows: examples show it running in scheduled jobs, GitHub Actions, and bots that publish screenshots to social media or use them in docs. It ships with detailed documentation, a tutorial, and a template repository that lets you spin up an automated screenshot pipeline. -

AI Commits
A CLI that writes your git commit messages for you with AI
AI Commits is a command-line tool that writes your git commit messages for you using an AI model. It works by running git diff to gather your staged code changes, sending that diff to an LLM (originally GPT-3, now configurable), and receiving back a concise, human-readable commit message. The tool is designed to integrate cleanly into a developer’s workflow so that generating a descriptive commit message becomes a single command rather than a chore. It supports configuration via environment variables or config files so you can set your API key, preferred model, message style, and more. There are also options to preview, edit, or regenerate the AI-proposed message before actually committing, giving developers control instead of blindly trusting the output. Because it’s published as an npm package and even as a Homebrew formula, installation is straightforward across platforms. -

Vouch
A community trust management system based on explicit vouches
Vouch is an open-source community trust management system that introduces an explicit vouching model to govern who is allowed to contribute to a project’s critical interactions, such as opening issues or submitting pull requests. Traditional open source has relied on implicit trust earned through effort, but the advent of AI-generated low-quality contributions has made maintainers seek more intentional vetting processes. With Vouch, existing trusted contributors explicitly “vouch” for new community members before they can participate in selected parts of the project, and they can also “denounce” users to block them should they act in bad faith. The system stores trust decisions in a simple flat file format that integrates easily with version control and can be parsed using standard tools, making the trust layer lightweight and transparent. -
18
mgrep
A calm, CLI-native way to semantically grep everything, like code
This project is a modern, semantic search tool that brings the simplicity of traditional command-line grep to the world of natural language and multimodal content, enabling users to search across codebases, documents, PDFs, and even images using meaning-aware queries. Built with a focus on calm CLI experiences, it lets you index and query your local files with semantic understanding, delivering results that are relevant to your intent rather than simple pattern matches, which is especially powerful in large or diverse projects. It also includes features such as background indexing to keep your search index up to date without interrupting your workflow and web search integration to expand the scope of queries beyond local files. Designed for both programmers and agents, it integrates naturally into development and research workflows while offering thoughtful defaults that keep output clean and informative. -

EnDiskEx
Bulk extractor for Ensoniq-formatted disk images
EnDiskEx is a command-line tool that bulk extracts instruments, sequences, songs, and banks from Ensoniq-formatted disk images (RAW, GKH, EDE, and EDA) for the EPS/ASR family of samplers. The extracted files are saved as EFE / SMF / TXT files. EnDiskEx is designed to extract Ensoniq banks for re-creation within a different DAW. It will track down the instrument and song files from bank references even if they were saved on another disk. There also exists a disk mapping feature to correct for any errors in this process caused by having relabeled disks, forgotten to label disks, etc. EnDiskEx has been tested and validated against a variety of RAW, GKH, EDE, and EDA images files the dev team has, including but not limited to, the ASR factory disks, the EPS 16+ factory disks, and the EPS (classic) factory disks. -

Live CD With Zerofree Utility i686 32Bit
A Custom Puppy Linux Live CD With Zerofree Utility i686 32 Bit
After Booting with this Live CD, just click on the CDROM icon on the Desktop, to open its folder contents, then Right Click the zerofree.sh file and Choose the "Run in Terminal" option and then follow the instructions shown on the terminal. As you may be aware, Booting with a Live CD, requires that you need to change the Boot Order on your System / Guest BIOS, quickly on startup, by pressing either F2 OR F12 OR F10 OR an equivalent key and then change the Boot Order to boot from the CDROM first. Some Hints: Puppy Linux Live CDs show some dialogs / settings window on first startup / first shutdown. Feel free to dismiss / close them, if you do not want to make any changes, to the live cd's operation, next time, on the same system. This will not affect the zerofree's work in any way. Apart from this, using the Internet Browser, built in, would require a Free Memory of 1 GB or more, for better Performance ( as it is generally a memory intensive activity ) -
