Retrieve patent abstract images through the Eureka patent data platform. Trigger this skill when the user mentions patent abstract images, patent drawings, patent illustrations, patent image searches, Eureka abstract images, patent figure lookups, Eureka, or related terms. Also trigger it when the user needs to view drawings or illustrations in a patent document, even if they do not explicitly say “abstract image”.
Query patent bibliographic information from the Eureka patent database, including titles, abstracts, applicants, inventors, classification numbers, priority claims, and cited references. Trigger this skill when the user mentions patent bibliography, basic patent information, patent titles and abstracts, patent applicants or inventors, patent classifications, IPC or CPC classifications, patent agents, patent examiners, priority claims, cited references, related documents, estimated expiry, or Eureka patent data. Also trigger it when the user needs basic bibliographic information about a patent, such as its title, abstract, applicant, or classification number, even if they do not explicitly mention “Eureka” or “bibliography”.
Use this skill when the user asks to “escalate privileges on Linux,” “find privesc vectors on Linux systems,” “exploit sudo misconfigurations,” “abuse SUID binaries,” “exploit cron jobs for root access,” “enumerate Linux systems for privilege escalation,” or “gain root access from a low-privilege shell.” It provides comprehensive techniques for identifying and exploiting privilege escalation paths on Linux systems.
This skill should be used when the user asks to “use Metasploit for penetration testing,” “exploit vulnerabilities with msfconsole,” “create payloads with msfvenom,” “perform post-exploitation,” “use auxiliary modules for scanning,” or “develop custom exploits.” It provides comprehensive guidance for leveraging the Metasploit Framework in security assessments.
Arrange opening positions for every scene in an AI short drama: first identify objects in the scene image that can be sat or stood on (projected onto a top-down plane), then assign each character in every scene to a side of an object, sitting or standing, facing direction, and whether extras are present. The program writes an opening blocking sentence for each scene; copy it into the first segment of that scene's storyboard. By default, deliver a draggable HTML tool report for adjusting positions; it can export staging.json in the page. JSON is also saved as working data, and Markdown can be exported as needed. All 8 quality gates are checked deterministically by script (number of identified objects, objects present in the image, exact cast count, every present character assigned to an identified object, no overlapping characters on the same side, specified extra positions, and more). Pre-fills the skeleton from novel-script's script.json and novel-art's art.json. Zero dependencies, zero API keys. Use when asked about blocking, staging, who sits where, seating arrangements, or staging for an AI short drama.
Operate and validate Obscura for JavaScript page loading, stealth browsing, anti-fingerprinting, tracker blocking, screenshots and visual comparison, CDP automation with Puppeteer or Playwright, screencasting, PDF export, MCP browser interaction, and web extraction.

Explore and optimize simulation parameters via design of experiments (DOE), sensitivity analysis, and optimizer selection — generate Latin Hypercube, quasi-random, or factorial sample plans, rank parameter influence with sensitivity scores, recommend Bayesian optimization, CMA-ES, or gradient- based methods based on dimension and budget, and fit surrogate models for expensive evaluations. Use when calibrating material properties against experimental data, planning a parameter sweep, performing uncertainty quantification, or choosing an optimization strategy for a simulation with a limited evaluation budget, even if the user only says "which parameters matter most" or "how do I calibrate my model."
Use this skill when the user asks about Phaser 4 asset loading, sprite sheets, texture atlases, image optimization, preloader scenes, loading bars, tile map assets, audio formats, bitmap fonts, free game assets, generated placeholder assets, asset organization, or asset pipeline performance.
This skill should be used when the user asks to "add tilemap", "create a level", "Tiled editor", "tile collision", "object layer", "create map", "tilemap not showing", "level design", "tile layer", "game map", "spawn point", "trigger zone", or "map collision".
Plan a user interview topic in PostHog — pick who to target (cohort, emails, or PostHog distinct IDs), draft what to ask about, and prepare the voice-agent context plus a question list. Use when the user asks to "talk to users", "check how users feel about X", "interview some customers", "set up a user interview", "run a user-research call", "find users to ask about Y", or otherwise wants qualitative feedback through a conversation. Walks the user through targeting (cohorts-list, persons-list, or accepting emails / distinct IDs directly), captures the topic, and prompts for agent context and questions before calling user-interview-topics-create. Cohort targeting is resolved to explicit emails/distinct_ids at create time — topics snapshot their audience and do not re-evaluate cohort membership later. Do NOT trigger when the user is uploading a recorded interview audio file (that's the separate UserInterview/transcript flow) or only browsing existing topics with user-interview-topics-list.

Fix a Sanity Studio custom form component (components.input, components.field, components.item, or a plugin's form.components) that suspends without its own Suspense boundary, so it loads without layout shift and never blocks new documents. Use when the console warns "The custom input/field/item component ... suspended without a <Suspense> boundary of its own" or "A form component ... suspended without a <Suspense> boundary of its own", when a custom form component uses React.lazy, use(), App SDK hooks (useDocumentProjection, useQuery, useDocument) or another suspending data library, or when a field or array item shows a skeleton that never goes away on new documents.
Conduz o brainstorm da Fase 0 de um fluxo SDD/AgentSpec por interação com o usuário: explora contexto, faz perguntas de descoberta uma por vez, coleta amostras, compara 2–3 abordagens, aplica YAGNI, valida incrementalmente e gera um BRAINSTORM pronto para a fase /define. Use para ideias vagas de software, automações, agentes, produtos ou features que ainda precisam de exploração antes de formalizar requisitos; também quando o usuário pedir para transformar uma conversa, problema ou notas iniciais em um brainstorm estruturado.
Fecha um ciclo de trabalho e passa o bastão para a próxima sessão: registra o que foi feito, o que ficou pendente (separando o que está quebrado do que é melhoria), quais são os próximos passos e o que não pode quebrar — e gera um prompt de retomada que funciona sozinho, sem depender da conversa anterior. Mantém um único arquivo de handoff por feature, com cada etapa nova no topo. Use quando o usuário disser que vai parar, que o contexto está acabando, que terminou uma etapa, que quer documentar para continuar depois, ou ao final da fase de Build de um fluxo SDD.
Build a knowledge base (KB) that AI can genuinely query: organize what you know about a domain into concepts (for understanding) and recipes (for doing), with an entry point, quick lookup, and size limits that keep the material usable. Create the project index on first use and register each new domain. For legislation and standards (normative profile), record each rule’s validity, its source with SHA-256, conflicts between sources, and the rule → source → test map. Recommended before starting an SDD workflow. Content is always reviewed by a professional: AI organizes and drafts, while the person with technical responsibility is accountable for what gets recorded. Use when the user wants to teach their context to AI, catalog laws, standards, manuals or internal policies, document a process, or complains about having to explain the same things again in every conversation.
