Complete Valyu API toolkit for AI agents. Use this skill when asked to perform real-time search across web, academic, medical, transportation, financial sources, content extraction from URLs, AI-powered answers with citations, or comprehensive deep research reports.
Geolocate or chronolocate a photo with tool-verified reasoning (where was this taken / when was it taken / photo geolocation / geo-guessing). Given one or more photos, intake.py does metadata, OCR and reverse image search (Baidu/Yandex) in one command; clues and candidates go on a candidate board (board.py) that ranks them and gives the next step; clues.py looks up calling codes, driving side, plates and area codes from region packs; for satellite and street view the machine ranks first and you look only at the top few (CLIP in sat_scan.py, DINOv2+SIFT in match.py); plus sun and shadow math, OSM Overpass and DEM skylines. Every conclusion is checked against real data; output is coordinates + error radius, evidence images and tiered confidence. Use when the user shares a photo and asks where was this taken / geolocate this / when was this taken / 这是哪 / 在哪拍的 / 帮我定位这张照片 / 网络迷踪 / 图寻 / 几点拍的.
Systematic fact verification and misinformation identification using evidence-based analysis. Use when verifying claims, checking facts, identifying misinformation, evaluating source credibility, or when the user asks to "fact check", "verify", "is this true", or mentions claims that need validation.
Add, enrich, and manage contacts in Joel's Vault. Fire the Inngest enrichment pipeline for full multi-source dossiers, or create quick contacts manually. Use when: 'add a contact', 'enrich this person', 'who is X', 'VIP contact', 'update contact', or any task involving the Vault/Contacts directory.
Vision-driven desktop automation using Midscene. Control your local desktop (macOS, Windows, Linux) or a remote Windows desktop over RDP with natural language commands. Operates entirely from screenshots — no DOM or accessibility labels required. Can interact with all visible elements on screen regardless of technology stack. ⚠️ In local mode this takes over the user's real mouse and keyboard. For web apps, prefer "Browser Automation" instead. Only use this for desktop-native apps (Electron, Qt, native macOS/Windows/Linux) that cannot run in a browser, or for driving a remote Windows host via RDP. Triggers: open app, press key, desktop, computer, click on screen, type text, screenshot desktop, launch application, switch window, desktop automation, control computer, mouse click, keyboard shortcut, screen capture, find on screen, read screen, verify window, close app, test Electron app, rdp, remote desktop, windows server, connect via rdp Powered by Midscene.js (https://midscenejs.com)
Morning rundown - today's meetings with account context, opps closing soon with stale flags, waiting customer emails, and the day's top actions. Use when the user says "daily briefing", "daily brief", "morning briefing", "what's my day", "what's on my plate today", "prep my day", "start my day", "morning rundown", or on a schedule.
A decision-support framework that evaluates systems, architectures, and strategies through the entropy (decay) vs. negentropy (growth) lens, while surfacing tacit knowledge gaps. Use whenever the user is making architecture decisions, evaluating system designs, reviewing technical approaches, choosing between options, auditing existing systems, or planning strategies. Also trigger when the user explicitly asks to “apply the negentropy lens,” mentions “entropy,” “negentropy,” “tacit knowledge,” “knowledge engine,” or “flip the switch.” Nudge activation when you detect the user is at a decision point—even if they haven't asked for this lens—by briefly noting the entropic/negentropic dimension before proceeding.
Generate a Startup Canvas combining Product Strategy (9 sections) and Business Model (costs + revenue) for a new product. An alternative to BMC and Lean Canvas that separates strategy from business model. Use when launching a new product or evaluating a startup concept.
Fetches Twitter/X post and Article content — text, author, engagement metrics and embedded media — downloading images locally and generating complete Markdown with image references. Use when retrieving a tweet's text or an X Article with images, or pulling post metadata for a Markdown/PKM record. Preferred over Jina alone for X Articles with images.

Pre-build product and feature risk review for founders, product managers, and AI-assisted builders. Use this skill when the user is about to build a landing page, MVP, SaaS product, internal tool, agent workflow, or major feature and needs to check demand, positioning, monetization, retention, trust, distribution, and adoption risk before implementation starts.
Read Twitter/X for financial research through opencli: the user's home timeline, tweet search, trending topics, bookmarks, a user's recent tweets, threads, articles, profiles, followers and following, and notifications. Use this skill whenever the user wants to know what people are saying on Twitter/X or fintwit about a stock, topic, or market event, check their feed or bookmarks, see what's trending, or look up an @account and its posts. Read-only: it cannot post, like, retweet, reply, or follow.
Formulate and audit real strategy using Richard Rumelt's "Good Strategy Bad Strategy": an honest diagnosis, a guiding policy, and coherent action instead of goals, vision, and wishful thinking. Use when the user mentions "good strategy bad strategy", "strategy kernel", "diagnosis guiding policy coherent action", "our strategy is just goals", "strategic planning", "mission vs strategy", "annual plan", or "is this actually a strategy". Also trigger when auditing a strategy doc or pitch deck for fluff, turning a goal list into real strategy, formulating strategy for a product or company, or finding leverage and proximate objectives. Covers the kernel of strategy, bad-strategy detection, and sources of power. For product positioning, see obviously-awesome. For uncontested markets, see blue-ocean-strategy.
Create a comprehensive product strategy using the 9-section Product Strategy Canvas — vision, segments, costs, value propositions, trade-offs, metrics, growth, capabilities, and defensibility. Use when building a product strategy, creating a strategic plan, or defining product direction
Richard Feynman’s thinking framework and communication style. Based on in-depth research across 40+ primary sources, distilling 5 core mental models, 8 decision heuristics, and a complete communication DNA. Use as a thinking adviser to analyze problems, examine decisions, and provide feedback from Feynman’s perspective. Trigger when the user mentions “from Feynman’s perspective,” “what would Feynman think,” “Feynman mode,” “feynman perspective,” or “Feynman technique.” It can also trigger when the user asks whether something is “cargo cult,” says “naming isn’t understanding,” asks whether a demonstration can replace an argument, or wonders “do I really understand, or have I just memorized the name?” Do not trigger for general requests such as “explain this” or “put it simply”—activate only for Feynman-style verification (cargo-cult detection, naming vs. understanding, and resisting self-deception).
Create, read, and manage calendar events and reminders using EventKit and EventKitUI. Use when adding events to the user's calendar, creating reminders, setting recurrence rules, requesting calendar or reminders access, presenting event editors, choosing calendars, handling alarms, observing calendar changes, or working with EKEventStore, EKEvent, EKReminder, EKCalendar, EKRecurrenceRule, EKEventEditViewController, EKCalendarChooser, or EventKitUI views.

It can also trigger when the user merely says "from an engineering realism angle", "march of nines", "building is understanding" or "jagged intelligence". Do not trigger when the user is simply asking ordinary AI-related questions — activate only when they explicitly want Karpathy-style thinking frameworks.
Multi-source research on a customer question or topic with source attribution. Use when a customer asks something you need to look up, investigating whether a bug has been reported before, checking what was previously told to a specific account, or gathering background before drafting a response.
Brainstorm product ideas for an existing product using multi-perspective ideation from PM, Designer, and Engineer viewpoints. Use when generating new feature ideas, brainstorming solutions for an identified opportunity, or ideating with a product trio.
Use when the user needs papers, citations, or authors from the Semantic Scholar corpus through AI2's Asta MCP tools, covering keyword or title search with venue/date filters, who cited a paper, author profiles and publications, ~500-word full-text snippets for evidence, and DOI/arXiv/PMID lookup. Trigger on "find papers on X", "who cited this paper", "papers by <author>", "recent work since 2024", "论文检索", "找论文", "文献综述", "谁引用了这篇", "某作者的论文". Also use for citation counts, h-index, or venue-scoped paper lists. Requires the Asta MCP server; routes intent to the right tool with context-safe limits and fields.
Use this skill when the user requests to generate, create, or write professional research reports including but not limited to market analysis, consumer insights, brand analysis, financial analysis, industry research, competitive intelligence, investment due diligence, or any consulting-grade analytical report. This skill operates in two phases — (1) generating a structured analysis framework with chapter skeleton, data query requirements, and analysis logic, and (2) after data collection by other skills, producing the final consulting-grade report with structured narratives, embedded charts, and strategic insights.
Use when writing, drafting, scheduling, or improving a Slack message, announcement, or reply sent via the Slack MCP tools (slack_send_message, slack_send_message_draft, slack_schedule_message). Covers Slack markdown formatting, message structure, thread etiquette, reactions, and scheduling, and points to the right dialect for canvases and Block Kit.
