Productize Yourself leads a one-question-at-a-time reflection across specific knowledge, leverage, accountability, and judgment. Rather than supplying answers, it mirrors and probes your responses until it can summarize your distinctive strengths, a personal positioning statement, a productization formula, and one next action. It is intended for career and founder self-discovery, not task management.

Lambda is a compact communication language for agents, built from concept atoms rather than translated English. Its vocabulary spans code, agent-to-agent messaging, evolution, social and emotional states, science, and related domains, with Python and Go parsers plus CLI translation and vocabulary tools; it is aimed at machine communication, not human-facing prose, and parts of the syntax and vocabulary are still evolving.

Start with a topic, product, or folder of source material, and the skill suite moves through research, evidence, drafting, visuals, SEO/GEO optimization, QA, and export. It produces a Markdown article and can also create Word, website, LinkedIn, and X versions. The core Markdown workflow needs no extra tools, while Word and rendered figures require optional Pandoc, Mermaid CLI, or Python packages; a human still reviews and publishes the result.

connect-codex-skill wires the OpenAI Codex CLI into Claude Code as a second opinion for diff reviews, adversarial plan critiques, and delegated rescue work. Its setup installs the CLI, completes OAuth, adds the OpenAI plugin marketplace, installs the Codex plugin, and verifies the connection after a restart. The workflow exposes slash commands for review, rescue, status, results, and cancellation. It requires macOS or Linux, a recent Codex CLI, and an eligible ChatGPT subscription.

Use this agent skill to compare API spending, rented-GPU self-hosting, and fine-tuning ROI from workload details in messages or project files. It fetches current prices, runs deterministic VRAM and cost calculations in a standard-library Python engine, and produces a sourced report. Treat the result as directional: default estimates exclude operations and engineering, assume one replica, and size model weights without full KV-cache demand.

clu coordinates multiple AI coding agents through a local SQLite issue tracker and single-binary CLI. It supports atomic issue claims, capability routing, dependency graphs, checkpoints, locks, mailboxes, milestones, and inherited context, while keeping writes in a local log. There is no daemon, server, account, or network requirement, making it suited to agents sharing one machine.

resend-skill helps an agent send transactional email, manage batches, verify sending domains, and check delivery status through Resend. It sets up DKIM, SPF, and a separate return-path, then can pair Cloudflare Email Routing with Gmail send-as so an address can receive replies and send as that identity. A Resend API key is required, and inbound mail needs a Cloudflare-managed domain plus a human verification step.

napkin reduces a sprawling strategy to three to six ordered phases, draws the condition that earns each transition, and marks a flywheel only when an output genuinely feeds back into the plan. It defaults to a compact ASCII sketch and can emit Mermaid or SVG through a small Node renderer, keeping the reasoning cheaper than repeated image renders. The skill works across many coding agents and refuses to invent a missing gate or pretend that a linear plan has a flywheel.

design-to-frontend takes an existing no-build React prototype from Claude Design and moves it toward a dev-ready frontend. It maps pages, components, tokens, and missing assets, can generate transparent images with OpenAI, then adds features and polishes hierarchy, interaction states, mobile behavior, localization, and accessibility. The workflow verifies edits in a real browser with fresh cache-busting ports. It is not a starter for a new Next.js, Vite, Vue, backend, or SEO project.

quiz-builder turns notes, textbooks, slides, or PDFs into one reusable HTML quiz that works offline in any browser. It supports single-choice, multiple-choice, true-or-false, fill-in, and flashcard questions, with instant grading and explanations for wrong options. Learners can save missed questions into named sets, filter by topic or type, switch between Chinese and English, and keep progress in localStorage. The output needs no build step, server, dependencies, or tracking.

thai-pdf-booklet renders Markdown into individual Thai PDFs or a bound booklet with a full-bleed cover, back cover, table of contents, page numbers, and per-page credit text. Its portable Node CLI bundles Chromium and embeds Noto Sans Thai, so macOS, Linux, and Windows users do not need pandoc, poppler, system Chrome, or system fonts. A native variant can use an existing Chrome, pandoc, and poppler installation instead of downloading Chromium.

Open Council routes a task through specialist employee prompts and a ten-member board of distinct perspectives before showing the result. Board members are expected to challenge unsupported claims, risks, tone, and usefulness; output passes only at 8-of-10 consensus with no hard veto. Light, medium, and heavy modes trade review depth for time and token use, and installing the full employee set also downloads many external skills. The portable SKILL.md works across several coding agents.

Polish Traditional Chinese writing for Taiwanese usage by removing formulaic openings, filler, translated syntax, and Mainland Chinese terminology. The skill combines language guidance with a terminology scanner, a six-dimension score, and a CJK-specific check for broken Markdown emphasis. It can be used while writing, editing, or reviewing Obsidian notes and other Chinese articles.

ks-deep-claim-audit turns a post, article, screenshot, or repository link into a claim-by-claim fact report. It maps each statement to source code, command output, dated URLs, or other primary material, classifies it as true, partly true, exaggerated, false, or unverified, and cross-checks the highest-risk conclusions. The workflow is read-only and refuses to execute untrusted repository code; when the underlying value cannot be obtained, it keeps the unresolved verdict instead of softening it.

Ardublockly lets users build Arduino programs with drag-and-drop blocks, view the generated code, and upload it to a board through a local Python service and the Arduino IDE. It is packaged as a desktop application for Windows, macOS, and Linux, with a browser-based core option as well. The documented setup requires Arduino IDE 1.6 or newer, and the project is still under development.

Google Ads Custom Affinity Builder turns a product, market, persona, and user-supplied sub-themes into a multi-tab XLSX with keyword, website, video, channel, and app signals. It uses yt-dlp for view-aware video search, enforces a 10K-view floor, checks a channel’s recent uploads rather than trusting one viral video, and sends candidates to an independent checker. The workbook is designed for Google Ads entry, with tab names constrained by Excel’s 31-character limit.

md2mindmap converts a local Markdown file or online Markdown URL into an interactive Markmap HTML file with zoom, folding, and PDF export. It can also create a Lark or Feishu whiteboard, or produce both formats. Users choose language, depth, format, and publishing; Feishu output needs authenticated lark-cli, while online input and deployment need network access.

MirrorX is the desktop client in an open-source remote-control stack; a complete self-hosted deployment also uses separate Portal Server and Relay Server components that can run on premises or in the cloud. The current client supports macOS and Windows and documents end-to-end encryption, GPU acceleration, and high-resolution remote control. The project is still at an early stage and does not guarantee backward compatibility. Linux, Android, iOS, and web clients remain work in progress rather than available targets.
