Productivity
Start-here router and tradecraft baseline for any investigation into a person, company, domain, image or selector. Sets authorised scope, turns a vague request into an answerable intelligence question, writes a collection plan, picks the right workflow for the starting selector, and applies source grading and competing-hypothesis discipline. Use for "investigate this person or company", "do OSINT on X", "where do I start", or any open-source intelligence, due diligence, background or attribution task. Applies across due diligence, fraud, threat intelligence, journalism and compliance. Reference at useosint.com/skills/investigate-anything.
Build an entity-relationship link-analysis graph of an investigation — nodes, typed edges carrying source and confidence, aliases, and temporal validity — to expose shared infrastructure, bridging nodes and the real principal behind a frontman. Covers Maltego, Neo4j and Cypher, Gephi, centrality and community detection, and entity resolution. Use when an investigation has outgrown a list and needs a graph, or when asked how a set of people, companies and domains connect. Applies to fraud-ring and shell-network detection, AML and sanctions-evasion analysis, and complex corporate-structure work. Reference at useosint.com/skills/graph-the-network.
Deep-dive a subject's social media presence — profile metadata, follower and mutual network, content analysis, and posting-time pattern of life across Instagram, Facebook, X/Twitter, TikTok, LinkedIn, Reddit, Telegram and Discord. Use when profiling a social account, mapping someone's associates, inferring a subject's timezone or routine from their posts, or archiving a profile before it is deleted. Applies to threat assessment and executive protection, insider-threat investigation, pre-litigation research, and personal exposure audits — with explicit limits on profiling uninvolved third parties. Reference at useosint.com/skills/pattern-of-life-from-socials.
Design research plans and paper architectures. Given a research topic or idea, generate structured plans with methodology outlines, paper structure, dependency-ordered task lists, UML diagrams, and experiment designs. Use when starting a new research project or paper.
Analyzes user-requested Screenpipe history windows to detect repeated research workflows, match existing scientific skills, and stage new skill drafts or composition recipes for review. Requires a reachable Screenpipe HTTP API, normally on localhost:3030. Detection and embedding inference run locally; the selected LLM receives redacted app/title cluster summaries and matched skill descriptions. Use only when the user explicitly asks to analyze their recent work and propose skills.
Track aircraft and vessels from public ADS-B and AIS broadcasts using ADS-B Exchange, Flightradar24, FlightAware, MarineTraffic, VesselFinder and Equasis. Use when following a tail number or flight, looking up an ICAO 24-bit hex code, registration or callsign, tracing a ship by IMO number or MMSI, checking a flag of convenience or port-call history, finding who owns a private jet or vessel, or analysing AIS gaps and dark-fleet behaviour. Applies to sanctions-evasion detection, trade and supply-chain compliance, asset tracing and recovery, and investigative journalism. Reference at useosint.com/skills/track-planes-and-ships.
Search and cite from local BibTeX/BibLaTeX .bib libraries, including Zotero exports. Use to find, filter, preview, export, or generate LaTeX/Typst citation snippets by topic, author, year, venue, DOI, arXiv ID, keywords, abstract, fields, recency, or claim support. Do not use for manuscript writing or polishing.
Research companies, directors, shareholders, and ultimate beneficial ownership in official corporate registries, filings, and offshore datasets—OpenCorporates, UK Companies House and the PSC register, SEC EDGAR, US Secretary of State registries, EU business registers, GLEIF LEI records, OpenOwnership, OpenSanctions, and the ICIJ Offshore Leaks database. Use when asked who owns or controls a company, to find a person's other directorships, or to untangle a group structure. Applies to KYB and UBO verification, AML and sanctions screening, nominee and shell-company detection, procurement integrity, and M&A diligence. Reference at useosint.com/skills/who-really-owns-it.
Improve academic paper writing quality for ML/CV/NLP-style papers with clear section structure, paragraph flow, and reviewer-facing presentation. Use when drafting or revising Abstract, Introduction, Related Work, Method, Experiments, or Conclusion; polishing figures/tables; checking claim-support alignment; or performing self-review before submission.
End-to-end workflow to establish where and when a photo or video was captured and whether it is authentic — evidentiary handling, metadata extraction, reverse image search for provenance, visual geolocation, chronolocation from shadows, and manipulation checks, ending in a location finding with a stated confidence radius. Use when asked to verify where an image was taken, confirm or refute a claimed location or date, or authenticate media before relying on it. Applies to insurance claims, litigation evidence, disinformation analysis, and conflict and human-rights documentation. Reference at useosint.com/skills/where-was-this-taken.
A vision intake conversation followed by the generation of three product documents — `docs/product-vision.md` (strategy and brand), `docs/prd.md` (technical spec for coding agents), and `docs/product-roadmap.md` (phased build plan with task checkboxes). Also captures the founder's answers as `docs/VISION.md`. Use when the founder says “plan my product”, “plan a product”, “define my vision”, “generate a PRD”, “create a roadmap”, “spec out my idea”, “help me build something”, or wants to turn an idea into shippable spec documents.
Browser automation using Playwright MCP. Navigate websites, fill forms, click elements, take screenshots, and extract data. Use when tasks require web browsing, form submission, web scraping, UI testing, or any browser interaction. NOT when only fetching static content (use curl/wget instead).
Pressure-tests a product idea before the founder invests in planning, building, or launching. Surfaces fatal flaws, tests whether the problem is real, maps real competition (including current behavior), plans first 10 customers, defines a 2-week MVP test, returns a strong/weak/pivot verdict, then sharpens `docs/product-idea.md` based on the founder's direction calls. Use when the founder says “validate my idea”, “pressure-test”, “is this idea good”, “find fatal flaws”, “stress test my idea”, or otherwise wants to evaluate an idea before committing.
Searches scientific and technical web content with Exa and extracts page or PDF text from URLs in batches. Supports scholarly discovery with the publication category and academic domain filters. Applies to requests to search the web, look up current research, fetch a page, or extract an article using Exa.
Craft advanced search-engine queries and Google dorks to surface hidden files, documents and mentions. Covers site:, filetype:, inurl:, intitle:, intext: and before:/after: operators, verbatim search, exposed directory listings, config files, backups and open S3 buckets, and the operator differences between Google, Bing, DuckDuckGo and Yandex. Use when building a Google dork, hunting a leaked document, or searching paste sites and document repositories for a name, email or selector. Applies to data-exposure audits, pre-engagement reconnaissance, competitive and regulatory research, and insider-leak investigation. Reference at useosint.com/skills/google-like-a-spy.
Guided discovery of a product idea by mining what the founder already knows or already does — covers source selection (business vs. expertise), context capture, pattern synthesis, candidate scorecard, and writes `docs/product-idea.md`. Use when the founder says "generate an idea", "help me find an idea", "what should I build", "product idea from my business", "product idea from my expertise", or otherwise needs to discover a product concept worth building.
Generate complete academic survey papers using multi-LLM parallel outline generation, RAG-based subsection writing, citation validation, and local coherence enhancement. Based on AutoSurvey pipeline. Use for writing comprehensive literature surveys.
AI-native tutor and onboarding workflow for the MCPA (Model Context Protocol Associate) certification in AI Engineering from Scratch. Use when a learner wants to prepare for the MCPA, resume their certification path, learn the next lesson interactively, run and verify practical labs, take the diagnostic or a full mock, or remediate weak exam domains from GitHub with Claude Code, Codex, ChatGPT, Cursor, or another agent.
Analyzes your recent Claude Code chat history to identify coding patterns, development gaps, and areas for improvement, curates relevant learning resources from HackerNews, and automatically sends a personalized growth report to your Slack DMs
Read Telegram channels and groups for financial news and market research with the tdl CLI: list chats and channels, find a channel by name, and export recent messages or a date or ID range. Use this skill whenever the user wants to check their Telegram, see what's new in their channels, read or export messages from a news, crypto, or trading channel or group, or gather market news and signals posted on Telegram. Read-only: it cannot send messages or join or leave channels.
This skill provides instructions for interacting with Todoist using the td CLI tool. It covers CRUD operations for tasks/projects/sections/labels/comments, and requires confirmation before destructive actions. Use this skill when the user wants to read, create, update, or delete Todoist data.
Help users run effective decision-making processes. Use when someone is facing a high-stakes decision, dealing with analysis paralysis, needs to align stakeholders on a choice, or wants to establish decision frameworks like DACI or RAPID.
Operate AgentMail from a shell with the official CLI. Use when the user wants commands for listing or creating inboxes, reading or searching mail, sending or replying, managing drafts, or scripting JSON/YAML output; do not use for SDK code, MCP setup, or framework adapters.
Builds today's call list. Runs lead-triage to rank the top-5 leads most worth calling, supplies talking points from email history, blocks time on the calendar, and drafts follow-up messages. Trigger on "call list," "who am I calling today," "top five to call today," or "block time for calls." An owner who wants leads scored or ranked with no calendar blocks routes to lead-triage directly. Accepts optional count and date arguments.
Help users plan products and strategy when outcomes are unpredictable. Use when someone is dealing with ambiguous timelines, building in fast-moving markets, planning AI/ML projects, or asking how to make commitments when they don't know what will happen.
Baidu Drive file management and content capabilities — upload, download, save to drive, share, search files, search text snippets, read full file contents, move, copy, rename, and create folders. Also supports Agent memory backup/restore (kimiclaw/maxclaw/qclaw/openclaw). TRIGGER: The user mentions "百度网盘/bdpan/网盘/云盘/baidu drive/Baidu Drive" in connection with file operations, or mentions memory-related operations such as "备份记忆", "恢复记忆", or "查看记忆备份". DO NOT TRIGGER: Non-file-storage operations or use of other cloud drive services; local memory organization/cleanup; PPT generation (now a separate baidu-wenku-aippt skill).
Runs the owner's Monday morning briefing as a two-link chain — business-pulse for the cross-connector snapshot of cash, sales, and pipeline, and report-builder for any saved KPI reports the owner has already defined — then reads the week ahead straight from Calendar and mail and merges all three parts into a single one-page Monday document, delivered per the owner's stored output preference. Requires no connectors and degrades gracefully, building from whatever of the ledger (MYOB, NetSuite, QuickBooks, Xero, or Zoho Books), Calendar, DocuSign, Expensify, Gmail or M365, HubSpot, PayPal, Ramp, RingEx Chat, Shopify, Slack, Stripe, and TikTok Ads is connected, or from pasted and uploaded data when none are. Trigger on "Monday brief," "start my week," "what do I need to know this week," "weekly briefing," "catch me up before Monday," or when the owner schedules a recurring start-of-week update.
Set up the initial file system for a new sandbox. Fetches the account's organizations and artists via the Recoup CLI and scaffolds the folder structure. Use when a sandbox has just been created and has no existing file system. Before running, check if the sandbox already has an orgs/ directory—if it does, this skill is not needed.
Claude as the trainer. Walks an SMB owner through connecting their first two tools, runs one recipe to prove immediate value, interviews them about their business (industry, size, top three headaches), stores that context persistently so every other skill benefits, and sets a weekly check-in cadence. Use when the owner is getting started or says any of: "set me up," "setup," "help me get set up," "get started," "help me get started," "get me started," "what can you do," "I'm new to this," or is in their first session.
Read-only storage analysis assistant for macOS / Windows (automatically detects the system). Scans disk usage across the entire computer, identifies what is taking up space, classifies each item into three levels—🟢 safe to clean automatically / 🟡 requires human judgment / 🔴 clean with caution—and provides actionable recommendations. Generates a polished, collapsible interactive HTML report with one-click command copying, and can launch a local service to delete items from a web page with one click (move to Trash/delete permanently). Scanning is read-only throughout. Always use in these situations: the user says “storage analysis,” “disk full,” “C drive/hard drive full,” “not enough space,” “free up space,” “clean disk,” “taking up space,” “what’s taking up space,” “help me check storage,” “check computer storage/space,” “storage space,” “computer is low on space,” “memory full/not enough/insufficient,” “check memory/storage” (in colloquial Chinese, “memory” often means storage), “disk cleanup,” “clear cache,” or “磁盘清理”; or complains that the computer is out of space, wants to know what is using the disk, or wants cleanup recommendations. Note: if the user explicitly means RAM (e.g. “which process is using memory,” “high memory usage,” or wants to view Activity Monitor), that is RAM, not storage, and is outside this skill.
A skill for searching WeChat Official Account articles. Uses WeChat search to retrieve article lists covering Chinese-language topics such as technology/AI, social affairs, finance, education, and careers. Search by keyword and return titles, summaries, publication times, source accounts, and links. Use when users need to find WeChat Official Account articles, compile references, or quickly get article information

Help users run effective post-mortems and retrospectives. Use when someone is reviewing a project that succeeded or failed, wants to establish learning practices, is dealing with failure aftermath, or needs to improve team learning loops.
Distill a book, long-video transcript, podcast, course, or interview into a coherent set of executable skills. Use when the user asks to "拆书" / "蒸馏一本书" / "把 XX 书做成 skill" / "把这个视频/播客/课程蒸馏成 skill" / "turn a book or video into skills" — i.e. wants the frameworks, principles, and methodologies in long-form content extracted into atomic, reusable Claude skills that an agent can invoke in real-world situations. NOT for simple summarization, book reviews, or role-playing as the author (that is nuwa-skill's job).
Produce a token-bounded, citation-ready context slice from an existing Obsidian vault for a downstream agent or task. Use for "/wiki-context-pack", "use my vault as context", "context slice for X", "pack the wiki for my agent", or "bounded context for Y".
Board meeting preparation, investor updates, and executive communication. Use when preparing board decks, writing investor updates, handling bad news with the board, structuring QBRs, or building board-level metric discipline. Includes the "Three Things" narrative model, the 4-tier metric hierarchy, and the pre-brief pattern that prevents board surprises
Decompose research ideas into atomic, self-contained concepts with bidirectional math-code mapping. For each concept, extract the math formula from papers and find code implementations. Use for complex system papers requiring formal grounding.
Installs, diagnoses, repairs, and personalizes the official Tencent IMA skill (a wrapper around upstream ima-skill, not a replacement), including fan-out search across IMA knowledge bases with priority boosting. Use when the user mentions IMA / 腾讯 IMA / ima-skill, needs IMA API key setup, 知识库搜索 / 笔记搜索, imports URLs into a KB to extract content, or hits "Skipped loading skill(s) due to invalid SKILL.md" (ima-skill's missing-YAML-frontmatter bug).
Send DingTalk messages. Use this skill when the user mentions “DingTalk message,” “send a message,” “send a notification,” “group notification,” “group message,” “Webhook,” “bot message,” “send a bot message,” “work notification,” “direct message,” “group chat message,” “recall a message,” “message read status,” “send Markdown,” “send a card message,” “ActionCard,” “@someone,” “@employee,” “at someone,” “remind someone,” “dingtalk message,” “send message,” “robot message,” or “work notification.” Supports all messaging operations, including custom group Webhook bots (text/Markdown/ActionCard/Link/FeedCard + signing + @someone), direct and group messages from enterprise app bots, message recall, read-status checks, and work notifications.
Help users navigate tough feedback, performance conversations, and conflict. Use when someone needs to give hard feedback, have a performance conversation, fire someone, address conflict with a colleague, or deliver disappointing news like a denied promotion
Comprehensive startup idea validation and market analysis tool. Use when users need to evaluate a startup idea, assess market fit, analyze competition, validate problem-solution fit, or determine market positioning. Triggers include requests to "validate my startup idea", "analyze market opportunity", "check if there's demand for", "research competition for", "evaluate business idea", or "see if my idea is viable". Provides data-driven analysis using web search, market frameworks, competitive research, and positioning recommendations
Control the user's real Safari browser on macOS through AppleScript, page JavaScript, screenshots, and carefully verified System Events input. Use when an agent needs to inspect or operate the user's existing Safari tabs and login sessions, including reading pages, navigating, clicking, filling non-sensitive forms, taking screenshots, observing page-level fetch/XHR metadata, or troubleshooting Safari-specific UI behavior.
