Find the open-source solution that fits.

biz-health-check looks up a Korean business registration number across public records and returns facts, sources, and lookup times side by side. Providers cover tax status, national-pension workplaces, published tax-debt lists, corporate basics, procurement sanctions, and regional permit status. It intentionally avoids scores or interpretation, downgrades unavailable providers instead of crashing, and requires a data.go.kr key for some services. Local permit matching also needs a region and may not provide the registration number itself.

DataEcho packages one skill for publishing a file, static site, or Dockerfile-based app to a live URL and another for persistent agent memory. Publishing supports anonymous uploads with a later claim, incremental deploys, and private Drives with scoped share tokens. The memory skill keeps a small index and one fact per file, with atomic writes, history, undo, and handoff between agents. The scripts use Bash and Python’s standard library, while credentials and stored memories remain account-scoped.

solution-drafter turns chats, meeting notes, and emails into formatted Chinese government or enterprise proposal documents. Its framework, document types, and domain plugins are separate, while five file-based stages handle intake, asset gathering, outline filling, content drafting, and revision. Missing source material stays marked for completion instead of being invented, and long documents are written section by section so completed work remains on disk if a run stops. The final output is a font-compliant DOCX.

wechat-typesetter is a reusable formatting specification for turning source text into inline-styled HTML that survives the WeChat public-account editor. It defines a two-color card system, eleven components, image-card wrappers, compatibility filters, and six self-checks. The source characters and paragraph structure must remain unchanged, with one output block per input paragraph. It targets WeChat on desktop and mobile; other publishing platforms are untested, and JavaScript is intentionally excluded.

lecture-builder combines a knowledge document, question document, and optional solution document into two printable DOCX handouts. The student edition leaves answer space after each problem, while the teacher edition adds answers and explanations. The engine copies source images, Word formulas, and tables at the XML level instead of retyping them, then applies fixed A4 layout, numbering, contents, and page elements. A small configuration file maps knowledge sections to questions; without a solution file, only the student edition is produced.

ai-landing-skill teaches compatible coding agents how to compose performative-ui’s React components into AI-startup landing pages. It includes recipes for hero, social proof, pricing, and waitlist sections, three worked examples, and rules such as using one hero centerpiece, keeping metrics plausible, and checking mobile layouts. The visual language is intentionally AI-startup oriented, so the skill defers for regulated industries, generic non-tech sites, app interfaces, or projects with an existing design system.

disk-cleaner-skill scans a macOS or Linux machine, classifies space usage by safety, and presents the findings in a local browser dashboard. It never deletes during discovery and asks for explicit approval before acting: pure caches may be removed, while review items move to the recoverable Trash and protected data is excluded. A dry-run, per-item approval, self-contained report, and append-only action log support inspection. The project is still v0.1 alpha, so the dry-run and backups remain important.

Next.js App Router Audit scans an App Router codebase with a zero-dependency Node tool for Server Component boundary mistakes, request waterfalls, client-side anti-patterns, and Core Web Vitals risks. It reports issues such as lost metadata, legacy head or image usage, needless client components, effect-based fetching, raw images, unsafe HTML, and missing streaming fallbacks, with severity-ranked fixes. A companion checklist covers judgment calls the scanner cannot prove, and JSON output can fail CI on errors.

Dope reads a person’s communication tendencies through four bird profiles—Peacock, Dove, Eagle, and Owl—and uses the selected profile to shape everyday messages, sales conversations, and relationship advice. The skill keeps the model, reading guide, and three playbooks in separate reference files, so an agent can load the relevant context for a situation. It is best used as a conversational hypothesis about how someone may receive a message, not as a permanent label.

App Store Connect Agent Skill maps plain-language requests to a bundled CLI for Apple’s official App Store Connect API. It manages listings, localizations, review replies, reports, media, TestFlight, builds, submissions, and releases from local agents such as Claude Code, Codex, or Cursor. It requires Node.js 22.12 or later, network access, and App Store Connect API credentials; it does not build or sign apps, and website-only tasks remain outside its scope.

smart-contract-audit reviews Solidity, Vyper, Solana, and CosmWasm code from an attacker’s perspective. It builds a system model and invariants, runs available analyzers, performs manual function-by-function review, and writes severity-rated findings with concrete exploit paths and remediation. The methodology also examines privileged roles, upgrades, oracles, cross-chain messages, and live deployment state before producing a GO, conditional GO, or NO-GO verdict. Coverage of other virtual machines is general and partial, and a clean report is not a guarantee of safety.

Pet Freedom researches whether a chosen animal species may be kept, bred, sold, or transported across countries, states, and territories, then publishes source-cited pages to WordPress. A species configuration drives the research, verification, and publishing flow; optional features can draft agency inquiries or build an advocacy toolkit. Credentials and private notes stay local, while public pages expose only safe fields. Laws change and local interpretation matters, so the project treats its output as research support rather than legal advice and asks readers to verify original sources.

ATS Score Builder compares a current resume with a specific job description, extracts exact phrases, pairs key acronyms with their full forms, and removes formatting choices that confuse resume parsers. It is a 15-step method with a template rather than a resume generator, and it never invents experience, titles, skills, or metrics. A final keyword scan helps measure the result.

getdocs turns a documentation site into a local Markdown tree that coding agents can search without repeatedly loading navigation, banners, or rendered HTML. It preserves URL structure, page metadata, and a crawl manifest, and prefers cloning an open-source repository’s original Markdown before falling back to crawling. Runs can target one section or a whole site, resume from output files, and report whether the result was crawled or cloned.

loom-flow makes a small set of Markdown files the durable memory for an AI coding workstream. The assistant moves from chat to idea, design, plan, implementation, and done records, rereads them in a fresh session, then stops after one requested step and records what happened. It has no build or MCP dependency; larger teams that need enforced writes, stale-state tracking, or a document graph can move to the separate Loom engine.

Pre-Prod Readiness Check detects a project’s stack and fans out read-only checks across 17 production-readiness categories, including authentication, billing, external requests, secrets, databases, AI safety, performance, compliance, and release operations. It merges duplicate findings and re-checks Critical and High items against their cited locations before producing a severity-grouped report. Mechanical fixes are drafted one at a time and require approval before application.

Cost & Margin Analysis inventories paid APIs, SDKs, scrapers, hosting, storage, messaging, payments, and other recurring surfaces in a codebase, then attaches rates from repository data, saved snapshots, or provider pages after permission to fetch. It models average, minimum-payment high-cost, and legitimate power-user scenarios per plan and feature, including payment fees. The scope is variable run cost and margin, not one-time build costs or formal finance and tax work.

Dual Subtitles SRT Skill combines English and Indonesian text into one subtitle track, keeping English above Indonesian while aligning cues, repairing timing, wrapping long lines, and rejecting overlaps or blank entries. Its scripts can probe media start offsets, shift active sidecars together, create exact-basename auto-load copies, and validate the four-line limit. It also renders frames from the actual movie for visual confirmation, so writing a file alone is not treated as proof.
