Find the open-source solution that fits.

embedded-uiux-walkthrough guides an agent to add tutorial routes or embedded tours to a web app using real components rather than screenshots. It covers demo-only data, no-write flows, fake cursors, target highlights, click and typing animations, iframe scroll or input locking, and mobile-aware targeting through stable data-tutorial hooks. Use it for onboarding, customer demos, or in-app training.

revisao-literatura-medica is for medical professionals and supports literature reviews across clinical topics, with POCUS as one use case. It searches PubMed, Europe PMC, and OpenAlex, verifies PMIDs and DOIs, resolves open-access copies through Unpaywall, and reads PDF or EPUB documents TOC-first, using OCR for scans. Outputs follow evidence-grading and guideline or study structures, and the skill only states claims retrieved from a real source in the current session. It requires Python dependencies; Telegram-library access stays in private configuration.

html-animation-to-mp4 captures HTML/CSS/JS animations in a headless browser and encodes the frames with ffmpeg. Claude Design .dc.html bundles can expose their own frame-seek hook, while --virtual freezes clocks and advances ordinary canvas, WebGL, or CSS animation frame by frame. It supports multiple aspect ratios and frame rates; capture is silent by default, and Playwright, Node, and ffmpeg are required for the CLI.

db-route-optimizer identifies N+1 queries, missing indexes, queries in loops, unbounded reads, and other route bottlenecks through query counts or EXPLAIN ANALYZE rather than guesswork. It saves a baseline, applies one isolated behavior-preserving change, re-benchmarks under the same conditions, and records the result. Tests and a query-count guard can stay in CI to prevent regressions, and the scripts also run without Claude.

agentrank-verify queries an x402 counterparty’s AgentRank before settling payment. The 0–1000 score is derived from real on-chain USDC settlements and weighted by payer reputation, and the check works through MCP, A2A, or a plain HTTP GET. It helps identify counterparties with verifiable settlement history, but a reputation score is a pre-payment signal rather than a guarantee of safety or delivery.

safedeps grounds dependency choices in current OSV vulnerability records instead of a model’s frozen training knowledge. When an agent is about to add a package and version, it checks for known flaws and can stop the suggestion before it enters the project. This is a narrow decision-time guard, not a replacement for npm audit, pip-audit, osv-scanner, or a broader CI security scan.

Humanize detects 29 concrete patterns associated with machine-written prose, then iterates through transformation, re-scoring, and keep-or-discard decisions for up to ten rounds. A writing sample lets it match your rhythm, vocabulary, and punctuation instead of imposing a generic voice. The final pass removes em dashes, en dashes, and double hyphens, and the plain skill runs without code dependencies.

logfrisk checks logging code and representative output for bearer tokens, emails, password hashes, error payloads, and other secrets or personal data. Findings include file and line locations, severity, and a suggested redaction; clear leaks can be replaced with redacted fields, while ambiguous cases are escalated for a decision. The skill keeps the work open until every leak is fixed or explicitly resolved.

gatekept verifies macOS application signatures with Apple’s codesign and spctl, flagging ad-hoc or unknown signers, injected dylibs, sideloaded apps, and Gatekeeper rejections. It also checks LaunchAgents, LaunchDaemons, Login Items, cron, shell startup files, temporary payloads, and hardening posture, then opens a self-contained local HTML report. The scan needs no account or dependency and does not modify the machine.

vault-crystallize has two separate workflows: crystallize updates recovery state and durable knowledge in Handoff.md only when something changed, while distill converts a concrete source into traced evidence entries. AGENTS.md owns workspace and write boundaries, and the vault protocols define schemas and contradiction handling. It is deliberately not a generic document-cleanup, deep-review, memory-sync, or polished-summary tool.

CardRadar reads your credit-card reward rules from your Notion database and chooses among the cards you actually own. For a purchase, it ranks real cash as min(amount × reward rate, monthly cap), so a high headline percentage cannot hide a low monthly ceiling. Card profiles, spending habits, and local IDs stay on your machine; this is a wallet-specific Claude skill, not a broad card catalog or payment app.

storyboard-prompter converts a one-line idea into one English prompt for an image model to render a multi-panel storyboard. It fixes the grid, aspect ratio, shared art direction, one beat per panel, and action logic so characters and style stay consistent across frames. The skill chooses common six- or nine-panel variants from natural language, but only produces prompt text; image generation happens elsewhere.

deep-think applies a staged reasoning loop to complex business, strategy, and decision questions: form hypotheses, examine counterarguments, test assumptions, self-evaluate, and rethink. It scores the response across coverage, logic, support, balance, specificity, and usefulness, adjusts effort to the question, and can wait for approval of the thinking frame. It relies mainly on supplied information rather than web research.

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.

Immos is a local immigration-preparation assistant that helps organize a person’s situation, compare visa pathways, inspect missing documents, plan deadlines from current official information, and draft application letters. It keeps the case files on the user’s machine and does not submit forms or act as a lawyer. Legal judgment, eligibility decisions, and complex histories remain with the user and an immigration attorney.

ai-title-generator turns an article or topic into Chinese titles for WeChat, Zhihu, and Xiaohongshu. Its professional tier maps each platform to one of three tech-media styles with a main and alternate title, while the Xiaohongshu tier uses first-person framing, emojis, and a pain-point hook. It is aimed at Chinese creators, product managers, and AI practitioners and avoids inventing hooks.

content-orchestrator routes a content request through research when freshness matters, WeChat article writing, humanization, and a final quality gate. It does not write the article itself; it coordinates the specialist skills and returns only the finished text, with a fallback when one child skill is unavailable. The intended result is source-supported, platform-aware copy rather than an unreviewed first draft.

claude-brain installs an interconnected Markdown knowledge base in a project, with session notes, a dense index, an append-only log, and a source registry. Its ingest command captures the current conversation, while query uses the wiki as a source for answers. It works with an Obsidian-style setup and can optionally use Notion as a source.
