Social Space places several websites or web applications side by side in one Windows window, then lets users save, update, and delete those arrangements as reusable workspaces. It is useful for repeatedly opening the same collection of social networks, dashboards, or online tools. Two browser-engine builds are offered: the Chromium version is lighter but may fail to play video on some sites, while the recommended Edge WebView2 version has broader compatibility but requires the Edge runtime and uses more resources. A matching .NET 6 runtime may also be required.

Cairn records trust ratings for web pages, search results, MCP tools, and network-bound commands so later agents can check how those resources performed for other reviewers. In Claude Code, post-tool hooks can rate calls in the background; Desktop and web installs expose explicit scoring tools instead. Each rating consumes either Claude subscription quota or Anthropic API spend, and rating data is sent to the Cairn service, so cadence and privacy controls matter.

DataPup is a cross-platform database client for developers who want a graphical place to write, run, and inspect SQL with AI-assisted query support. The current documentation lists ClickHouse and PostgreSQL as supported databases, with database-specific query execution already available. MySQL and SQLite are described as upcoming rather than usable today. The provided getting-started path focuses on installing source dependencies, running the development build, or creating a distributable package.

png-to-drawio reconstructs a PNG or AI-generated architecture diagram as editable draw.io vector shapes and can also emit a native PowerPoint with real objects for boxes, icons, and labels. It favors recreation over importing a flat image, preserving structure for versioning, editing, and re-export. The skill is useful when a polished raster diagram needs to become an engineering artifact.

Define the goal, non-goals, and a verifiable done condition, and the skill scaffolds the vision, specs, plan, prompts, and Bash engine for a repeatable loop. After one plan approval, a maker and separate verifier iterate one task at a time, run checks, and commit checkpoints. It is designed for a single-machine Git repository and needs the claude CLI for unattended runs; you still review the final diff and evidence.

EXPOUNDER turns a napkin-thin project brief into a layered specification without drifting into a different idea. It first asks permission, then uses three to five sharp questions to anchor the north star, scope, platform, and key distinction. The spec records assumptions, stops only for decisions that would change the project, and ends with a build handoff containing a kickoff prompt and first tasks.

Bump Java Version detects the effective bytecode target across a Maven or Gradle project, then performs one hop such as 8→11 or 17→21. It records the old-JDK test baseline, applies OpenRewrite and build adjustments, and checks compilation, retained tests, and the new target under the new JDK. Each hop needs both JDKs, the project build tool, and Maven Central access.

claude-conversion-copy diagnoses an audience’s awareness, desires, beliefs, and exposure to competing pitches before choosing how to write. In write mode it produces sales pages, landing pages, ads, emails, VSL scripts, headlines, and CTAs; in diagnose mode it finds the biggest leak, supplies a rewrite, and ranks fixes. The skill is built for conversion work that needs judgment, not a generic headline formula.

Orbital turns folders of local videos and images into a gallery-style desktop library, making it easier for editors and photographers to scan large media collections. It searches filenames across subfolders, supports keyboard-driven previews, and lets users drag media directly into applications such as iMovie or DaVinci Resolve. The workflow is local-first, so files do not need to be uploaded to a hosted service. Its source is available, but the author explicitly asks users not to redistribute packaged builds.

This skill wraps the upstream chbs command instead of reimplementing passphrase generation. It produces xkcd-936-style six-word phrases, shows an entropy caption, and supports count, capitalization, and separator variants; the upstream package must be installed and chbs must be available on PATH.

This skill coordinates a pull request lifecycle across GitHub and Codeberg: branch, commit, push, open issues and PRs on both hosts, squash-merge, reconcile divergent hashes, and remove branches. It expects gh authentication, a CB_TOKEN environment variable, matching remotes, and preset CryptoJones, Aaron, and Nebraska conventions.

This skill manually reprioritizes the Claude Code task queue by deleting and recreating tasks. Its planned triage CLI only suggests an order from task signals, while a human confirms the change; it never executes queue reordering automatically.

This skill wraps the upstream interruptingcow package and its moo command to notify an operator through Telegram when a long task finishes, fails, or crosses a time threshold. It does not reimplement the HTTP client; users must provide a Telegram bot token and chat ID, and handle the underlying task lifecycle themselves.

Build a reusable candidate knowledge base from your resume, portfolio, projects, and past interviews, then research the company, role, and product against the job description. The skill identifies weak or unclear evidence, drafts likely HR and hiring-manager questions with answers grounded in your real experience, and prepares a natural outreach message. Fresh company or interview information still depends on web access or materials you provide.

visual-screen-flow lays real, runnable components from a repository on an infinite canvas so multi-step and branching UI flows can be inspected together. A separate flow JSON stores arrows, notes, lanes, and positions, while stable references resolve each node to the actual component without embedding source code. It is framework-agnostic and suited to onboarding, checkout, auth, and other state-heavy prototypes.

mikeross turns OCR’d PDFs or document collections into an interlinked Obsidian vault where every note cites its source page. Its question mode answers only from the vault or admits that the material is missing, while mapping and graph modes help organize large collections and flag gaps. The skill is designed for grounded research with pypdf required and optional OCR support for scans.

ask-seranking-api classifies a question across the SE Ranking Data API, Project API, and MCP server, locates the relevant entry in its document map, and reads the current official page before answering. Each response includes a direct citation to the supporting section, while a script and scheduled GitHub Action refresh the URL index when the documentation sidebar changes. It is useful for developers who need precise endpoint, parameter, and error guidance rather than remembered summaries.

pick-to-edit opens a local browser picker so you can highlight and select the exact webpage element to change. It copies a CSS selector, XPath, and text preview with your annotation, then gives Claude a precise address for the HTML, CSS, or JavaScript edit. Keyboard navigation, layer switching, Shadow DOM isolation, and zero runtime dependencies keep the workflow focused on the chosen element.
