Tools

Econometrician Pedro Sant'Anna's academic Claude Code setup (fork the repo to use it): Beamer/Quarto lecture slides, paper review and mock refereeing, R/Python analysis and replication packages, with specialist subagents and quality gates. Needs Git and Python; slides need XeLaTeX and Quarto.

Fixes spacing and full-width/half-width punctuation in mixed CJK and English text, understanding 28+ file types including Markdown, YAML and strings and comments in source code. Lint mode outputs a diff or JSON for CI checks on localized copy.

Reads and writes Obsidian vaults from the terminal: search, view, create, edit, move and delete notes, and manage frontmatter and daily notes, without Obsidian running. Good for agents maintaining a personal knowledge base. Formerly Obsidian CLI.

Web search through DuckDuckGo plus fetching and parsing page content, with built-in rate limiting and LLM-friendly result formatting. No API key needed; runs with a single uvx command.

Uses the Qdrant vector database as a semantic memory layer for agents: store information and retrieve it by meaning, connecting to a remote instance or a local path, with FastEmbed generating embeddings by default. Maintained by Qdrant.

HR skills plugin: write inclusive job descriptions, build 30/60/90-day onboarding plans, design and analyze engagement surveys, and plan redundancy consultations (UK employment law by default) and organizational change. Text-only, no account; have legal or senior HR review redundancy plans.

Recruiting and sourcing skills: generate Boolean and X-ray search strings, plan sourcing strategy and draft candidate outreach, plus interview question banks, scorecards, reference-check scripts and offer letters, with an emphasis on structured, fair evaluation. Text-only; no account needed.

People-management skill pack for managers and HR with 7 skills: performance reviews, performance improvement plans (PIPs), 360-degree feedback surveys, interview scorecards, team health checks, team offsites and a 90-day plan for new managers. Text-only; no account or API key.

Audio plugin suite: transcription with local Qwen3-ASR or Whisper (MLX on Apple Silicon), speaker diarization, transcript correction, structured meeting notes and StepFun TTS. StepFun ASR and TTS need an API key.

Connects LLMs to ROS and ROS 2 robots: publish and subscribe to topics, call services and actions, set parameters, and read sensor and robot state, without changing robot code. The robot side needs rosbridge running.

Crawls an entire site, counts words and keywords per page, and checks technical SEO such as titles, meta descriptions, image alt text, H1s and social tags. Outputs JSON by default or an HTML report for agents to act on. Needs Python; the optional AI content review needs an API key.

Two-stage paper skills: planning studies the style of your target preprint server (e.g. PhilArchive, arXiv), finds gaps in the literature and scores a seven-dimension mock review; writing drafts and checks each chapter from the outline. Suits philosophy and interdisciplinary work; needs Python 3.

Helps managers and HR partners prepare tough performance feedback: frameworks like GAIN and Radical Candor, turning judgments into observable facts, role-playing the conversation, and planning follow-up. Distilled from Lenny's Podcast and Newsletter guests; prompt-only, no account needed.

Hiring lessons from 21 Lenny's Podcast and Newsletter guests on recruiting product managers and engineers: defining the role, sourcing through networks, assessing potential and closing offers, with frameworks and question lists. Methodology-focused, for recruiters and hiring managers.

Collects hiring advice from dozens of Lenny's Podcast and Newsletter guests to help you design realistic work samples or paid trials, shared rubrics and solid reference checks, instead of hiring on interview polish and resumes. Geared to product and tech teams; prompt-only, no account.

76 product skills distilled from Lenny's Podcast and Newsletter, covering product strategy, prioritization, user interviews, PRD writing, OKRs, launches and growth, hiring and team management. Each includes frameworks, checklists and templates, with verified quotes. Docs only, no account.

Turns a paper (arXiv link or PDF) into method diagrams, slides with a generated image per page (PPTX/PDF export) and an in-depth HTML explainer with formulas, for lab meetings and lectures. No API key; images use Codex's built-in generator or, in Claude Code, a separate image skill.

Opens HTML, Markdown or localhost pages in the browser via npx human-review so you can edit text directly and leave anchored comments, then sends every edit and comment back to the agent in one batch to apply to the source.

Community CLI for Feishu (Lark) focused on two-way conversion between Markdown and Feishu docs; also works with wikis, sheets, Bitable, messages, calendar, tasks and meeting notes, and ships 9 agent skills. Setup creates an app via QR scan; search and mail need extra user authorization.

Gives agents controlled access to MySQL: list databases and tables, inspect schemas and sample data, and run SQL, with multi-database mode, SSL and SSH tunnels. Configure your own database user, ideally with least privilege.

Submission skill packs tailored to 700+ journals and conferences, from AER, Nature and NEJM to top CS venues and leading Chinese journals, to revise papers to each venue's scope, style and requirements. Add its Claude Code marketplace per the README, then install packs per journal.

Generates book covers, movie posters, article covers and social images from one sentence, picking colors and composition from 30+ poster masters' styles to suit the subject. Rendering directly needs Python and a PipeLLM image API key; or just generate prompts for another image tool.

Marketing skills for the AI search era: brand positioning from a website URL, SEO/GEO keyword and AI prompt research, Reddit opportunities, content planning and writing, backlink plans, and audits of how citable your site is to AI. Some scripts need Node.js; site-code changes need a developer.

Pulls new papers from Hugging Face Daily Papers and arXiv, scores them by research area into a recommendation page, and writes deep-read Obsidian notes for key ones; can also batch-read Zotero collections. Needs Python 3, Obsidian and poppler; copy the whole skills folder per the README.
