Start with the job, then find an open-source answer

agent-token-usage-skill maps a natural-language question to the underlying atu CLI, then summarizes local session-log usage across Codex, Claude Code, Pi, Grok, opencode, and openclaw. It reads files already on your machine, makes no network call, and needs no API key. The skill installs across platforms, although the bundled CLI installer differs between macOS or Linux and Windows.

ByteDa Skill turns a short design brief into assets such as posters, long images, social graphics, presentations, comics, or H5 pages. It calls the ByteDa MCP service through a self-contained Python standard-library CLI, so the host client does not need a separate MCP setup. A ByteDa API key is required.

Distill Figure helps developers build interactive explanations with plain HTML and ES modules. Its reusable components cover linked graphs, matrices, plots, controls, and chart wrappers, while the render and probe tools check multiple widths and real pointer or keyboard interactions. It is useful when visual polish must be accompanied by working interactions, without a bundler or framework.

This skill turns a short description into an editable Google Sheet for CRM, orders, or general records. It proposes columns, keeps dropdown values on a separate Lists tab, and applies section colors and practical formatting. With the Chrome extension connected it edits a live sheet; otherwise it can generate an XLSX or CSV fallback.

MNB Claude Skills bundles ten independent workflows for Indian legal documents, GST invoicing, startup compliance, pitch decks, outreach, content, interviews, data cleaning, and technical handoffs. The skills require no API keys and can be used separately. Legal, tax, and compliance outputs are preparation aids and should be reviewed by a lawyer, CA, or CS for high-stakes use.

This Claude skill turns a French description of dates, times, and locations into a Framadate poll. It calculates the options, fills and publishes the form in a connected Chrome browser, then returns both the share link and the private administration link. It is useful for recurring meetings or volunteer schedules, but requires Claude desktop Cowork and the Claude in Chrome extension.

This Claude Code skill writes and revises Brazilian Portuguese for articles, posts, scripts, newsletters, emails, sales pages, proposals, and documentation. Its references target translation-like phrasing, filler vocabulary, and repetitive structures, followed by a post-writing checklist. The stated goal is clearer, more specific prose rather than text shaped to satisfy unreliable AI detectors.

Magyar-eladó researches public Hungarian marketplace listings, estimates quick-sale, market, and patient prices, recommends suitable platforms, and writes platform-specific listings with photo folders and a posting checklist. Optional browser assistance stops before final submission by default; Facebook is never DOM-automated, while an explicit auto-submit flag is available at the user's own risk.

Rethink adds a structured second pass after an agent has proposed a plan. It audits load-bearing assumptions, checks questions against sources, considers the strongest opposing case, runs a pre-mortem, and records the delta between the original and revised plan. Use it only when a concrete plan exists and the thinking budget is raised; extra self-review is not presented as a guarantee of improvement.

Claude LazyCodex Skill lets Claude delegate coding work to Codex and the LazyCodex harness in a live tmux pane. It selects planning, looping, or team commands, watches the session, answers questions, and independently runs builds or tests before reporting back. The setup requires Claude Code inside tmux plus a signed-in Codex CLI and LazyCodex.

Work Backstory records the causal story behind a code change while the work is happening: intent, decisions, rejected approaches, surprises, and lessons. Each problem-solving arc lives under docs/work-backstory and links to related commits in both directions. A plugin can add a one-line compaction checkpoint, but continuous capture remains the main protection against context loss.

Rehelios Video Skill guides a developer or coding agent through uploading or importing a video, waiting for processing, reading its playback URL, and embedding an adaptive HLS or DASH player. It covers public playback, signed tokens, domain allowlists, captions, and the REST API, CLI, or MCP paths. Rehelios charges by stored and delivered gigabytes.

Claude Book Skill guides a nonfiction project from interview and voice calibration to research, chapter drafting, editing, reader review, and DOCX compilation. Six specialized roles keep the work separated, while the researcher sources claims or flags gaps instead of guessing. You can provide writing samples from files or connected services, and the compiler can reuse formatting from a sample document.

YouTube to Article turns a YouTube or podcast link into a detailed Traditional Chinese reading article with timestamps that jump back to the source. It also creates a transcript, digest card, chapter mind map, quiz cards, and a local review page, and can ingest PDFs, web articles, Markdown, or Word files. The workflow runs locally, but some input types require optional tools such as ffmpeg or PDF extraction.

Powerhouse Clarity Coach leads an entrepreneur through five phases covering values, vision, scheduling, business validation, and mindset blocks. It turns the conversation into a full-picture analysis, an Eisenhower goal matrix, a personalized reflection question, and reusable weekly and milestone templates. The skill is intended for personal development and does not replace therapy, medical, legal, or financial advice.

This toolkit helps teams plan and interpret user research before building. It creates research plans, screeners, and non-leading interview guides, then turns transcripts or notes into thematic or matrix-based synthesis with an explicit build, pivot, or kill decision. Local DIY use is the default with no account or network required; community, synthetic, and paid backends are optional.

SSCI Academic Writing Skill supports English social-science papers from topic and journal selection through the introduction, literature review, methods, results, and pre-submission checks. It combines structural guidance, reusable sentence patterns, method-specific reporting conventions, and a checklist for common desk-rejection problems. It is aimed at graduate students, early-career researchers, and mentors working across management, finance, education, psychology, and related fields.

Linear Methodology teaches an agent how to structure project tracking rather than merely call Linear’s API. It derives milestones and workstreams from the project’s stated goal, backfills completed work from evidence in release history or git, and wires real dependencies without duplicating an existing setup. Use it to bootstrap a new project, extend an already-tracked project, or reconcile stale tracking.
