Use when: сотрудник, сотрудники, список сотрудников, создать сотрудника, заблокировать сотрудника, уволить сотрудника, тег, теги, группа сотрудников, добавить в тег, онбординг, оффбординг. NOT for: мой профиль, мой статус, найди сотрудника, найти сотрудника, кастомные поля, дополнительные поля, получить профиль, мой профиль, установить свой статус → pachca-profile, → pachca-chats, найти сообщение по тексту, полнотекстовый поиск → pachca-search.
Top-tier conference paper writing skill - guides the full writing process from draft to final version from a strict reviewer's perspective. Use it when the user wants to write a paper, improve a paper draft, revise specific sections (introduction, method, experiments, conclusion), polish academic English, respond to reviewer comments, or asks "how should I write this part". Trigger words include: 写论文, paper writing, improve my paper, 帮我修改, review comments, rebuttal, LaTeX, NeurIPS/ICLR/ACL submissions. Applies to all academic paper writing scenarios.
Use when the user needs PDF generation, manipulation, form filling, table extraction, OCR, merging, splitting, watermarking, or metadata handling.

Strategic planning for Product Hunt launches. Use this skill when you need to define launch objectives, create a preparation timeline, or develop an overall launch strategy. Helps with goal-setting, timeline creation, and strategic decision-making.
Reason about pharmacoepidemiologic study design for causal inference from real-world data — choosing active comparator new-user designs, emulating target trials, avoiding immortal time bias, handling time-varying confounding with marginal structural models, and selecting propensity score methods. Use when the user asks to design a drug safety or effectiveness study, choose between propensity score matching vs weighting vs stratification, emulate a target trial, handle immortal time bias, apply marginal structural models, assess unmeasured confounding with E-values, select an active comparator, define a new-user cohort, or evaluate a pharmacoepidemiology study design. Triggers include "active comparator", "new-user design", "target trial emulation", "immortal time bias", "propensity score matching", "IPTW", "marginal structural model", "confounding by indication", "E-value", "negative control outcomes", "quantitative bias analysis", "time-varying confounding", "prevalent user bias", "washout period", "landmark analysis", "stabilized weights".
This skill should be used when the user asks to "brainstorm a game idea", "help me come up with a game", "I want to make a game but don't know what", "is this game idea any good", "what should I build", "refine my game concept", "scope this idea down", "what genre fits", "help me pick a game to build", "turn this idea into something buildable", or arrives with a vague concept that needs shaping before a GDD can be written.
This skill should be used when the user pastes raw player feedback, playtester notes, bug reports, Discord or Reddit comments, itch.io comments, App Store reviews, QA notes, or a list of complaints about their Phaser game, or asks to "triage this feedback", "fix what players reported", "reproduce this bug report", "act on playtest notes", "turn feedback into tests", "what should I fix first", or "respond to this reviewer". Use it whenever feedback about a running game needs to become reproducible tests, prioritised fixes, and a verified re-release.
Pick the right library for a given frontend task from a curated, opinionated list — numbers, OTP inputs, charts, command menus, virtualization, drag and drop, toasts, state, styling, and more. Only runs when explicitly invoked; it does not trigger on its own.
Turn a complex, thought-through requirement into a detailed execution plan document plus a self-contained launcher prompt for a fresh agent session, and later review that session's report. Use when the user wants a plan before execution, wants execution handed to a separate session, or mentions 执行计划 / 计划文档 / 新会话执行 / 交接 prompt / 审查 report; also when reviewing a plan's execution report or dispatching a fix round. Grills what is still missing, applies ponytail taste, treats partial completion as legitimate, and never executes the plan itself. Prefer steady-do for implementation in this session and quick-do for clear, bounded changes.
Automates browser interactions for web testing, form filling, screenshots, and data extraction. Use when the user needs to navigate websites, interact with web pages, fill forms, take screenshots, test web applications, or extract information from web pages.

Do NOT use when: sufficient internal market research already exists, or only a simple size estimate is needed without in-depth analysis.
Use when: coordinating technical solutions with the engineering team, assessing technical feasibility, defining technical architecture, evaluating third-party services. Do NOT use when: the technical solution has already been decided by the engineering team, or when only a feature description is needed without technical evaluation.

Use this skill whenever the user wants to generate an AI video from text or image, use any AI video model, check Pollo credits, or mentions Pollo AI, pollo.ai, or any of the supported model names. Even if the user just says "generate a video" or "make me a short clip" without mentioning Pollo, this skill should be used.

Transforms overwhelming backlogs into clear, actionable priorities by mapping items on a 2x2 effort-vs-impact matrix, identifying quick wins (high impact, low effort), big bets, time sinks, and fill-ins. Use when ranking backlogs, deciding what to do first, prioritizing feature roadmaps, triaging bugs or technical debt, allocating resources across initiatives, identifying low-hanging fruit, evaluating strategic options, or when user mentions prioritization, quick wins, effort-impact matrix, high-impact low-effort, big bets, or "what should we do first?".
Three orthogonal analytical operations (WHERE/WHEN/WHY) + cross-operation synthesis. Each operation attacks the problem from a fundamentally different angle. The disagreements between the three ARE the valuable output. Works on any domain — code, business, strategy, design, text.
Generate ProcessOn-compatible editable diagrams and optionally render images through the ProcessOn API. Use when the user explicitly requests ProcessOn, hosted editable diagram output, or API-rendered flowcharts, swimlanes, sequences, architectures, ER diagrams, org charts, timelines, or infographics. Requires PROCESSON_API_KEY for remote generation. Prefer Mermaid for ordinary Markdown-native diagrams and PlantUML for strict UML/C4 source.

Multivariate severity assessment and humane endpoint prediction for laboratory animal studies using the RELSA (RELative Severity Assessment) score and ARIMA-based foRcast forecasting. Use when combining welfare readouts — body weight or weight loss, body temperature, clinical or nesting scores, biomarkers, activity, heart rate, burrowing, wheel running — into one severity score per animal per day, when asking which animals are at risk of reaching a humane endpoint or when one will be reached, when defining attention/danger zones or thresholds on a severity scale by kernel density estimation, or when reporting severity for a 3Rs, refinement, animal-welfare, or EU Directive 2010/63/EU severity-assessment context.

New to MCP?
From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
