Alibaba Cloud RAM permission diagnosis and repair assistant. When an agent encounters any permission-related error while operating Alibaba Cloud resources (403, NoPermission, Forbidden, AccessDenied, InvalidSecurityToken, etc.), or when the user describes an Alibaba Cloud RAM permission issue, use this skill immediately. Do not wait for the user to explicitly request it — proactively start the diagnostic process whenever a permission error appears. Also applies when: a developer encounters permission issues while writing Alibaba Cloud SDK code, the user asks how to configure minimum permissions for an operation, or the user wants to know which permissions the current identity is missing.
Connect directly to the Amap (Gaode) Web Service API via scripts for geocoding, reverse geocoding, IP location, weather, route planning, distance measurement, and POI queries. Use when the user asks for "Amap queries", "route planning", "geocoding", or "POI search", or when the Amap API needs to be called from a command-line script.
Expert-level Ansible for configuration management, automation, and infrastructure as code. Use when the user mentions automation, configuration management, infrastructure as code, playbooks, or roles, or when the task involves Ansible Architecture, Basic Inventory, YAML Inventory, or Dynamic Inventory.
Build acceleration skill for C/C++ projects. Use when reducing compilation times with ccache, sccache, distcc, unity builds, precompiled headers, split DWARF, or IWYU. Covers caching strategies, distributed compilation, link time reduction, and diagnosing build bottlenecks. Activates on queries about slow builds, ccache, sccache, precompiled headers, unity builds, split-DWARF, or reducing C++ compile times.
Local drop-in API emulator for Vercel, GitHub, Google, Slack, Apple, Microsoft, AWS, Clerk, Linear, Twilio, and other developer APIs. Use when the user needs to start emulated services, configure seed data, write tests against local APIs, set up CI without network access, or work with the emulate CLI or programmatic API. Triggers include "start the emulator", "emulate services", "mock API locally", "create emulator config", "test against local API", "npx emulate", or any task requiring local service emulation.
Integrate Firecrawl `/map` into product code for URL discovery on a known site. Use when a feature needs to find pages before scraping or crawling, especially on large docs sites, blogs, or help centers where the exact target URLs are not known yet.
Draft commercial agreements (NDA, MSA, SOW, SaaS, vendor) from user terms and deal context—signature-ready layout, counsel review required, no invented law. Use when the user asks to draft, author, template, or format a contract or agreement (not review-only). Create contracts with AI-native design and the highest aesthetic standards, powered by the K2F format and engine. Purpose-built for AI agents, K2F lets them focus on semantic content and design intent while automatically handling layout, typography, and formatting complexity.
Plan, implement, or improve an internationalization and localization strategy for UI content, formatting, and regional adaptation. Use when the user asks to add i18n, localize, translate, support multiple languages, handle regional formats, manage locale switching, or build a multilingual product.
Operates NoxInfluencer creator intelligence and marketing systems through the CLI. Use when work needs NoxInfluencer data, creator analysis, a Nox-native workflow, campaigns, CRM, outreach operations, monitoring, exports, account setup, quota, or troubleshooting; returns verified evidence and system state for standalone expert use or a wider marketing plan.
Generates production-grade Playwright automation scripts and E2E tests in TypeScript, JavaScript, Python, Java, or C#. Supports local execution and TestMu AI cloud across 3000+ browser/OS combinations and real mobile devices. Use when the user asks to write Playwright tests, automate browsers, run cross-browser tests, test on real devices, debug flaky tests, mock APIs, or do visual regression. Triggers on: "Playwright", "E2E test", "browser test", "run on cloud", "cross-browser", "TestMu", "LambdaTest", "test my app", "test on mobile", "real device".
Perform a thorough quality review of a pull request or feature branch before merging. Use this skill whenever the user asks to review a PR, check if code is production-ready, assess quality, verify docs are updated, or asks "is this ready to merge?", "review this PR", "check quality", "is this production ready?", or similar. Also use when reviewing your own work before submitting.
Render a proposed redesign of a page on the current website as a self-contained static HTML file, then iterate via the impeccable craft loop. Per-page, idempotent, stale-aware. Use when the user asks for a redesign prototype, a before/after comparison, a design preview, a page mockup, a visual diff of the redesign, or invokes `$stardust prototype` (`/stardust:prototype` in Claude Code).
Review code for any Frappe application — a checklist distilled from years of engineering practice on correctness, security, performance, concurrency, readability, API design, and testing. Use this when reviewing a diff, a PR, or a piece of code for quality and security, or when you want a reviewer's checklist grounded in hard-won Frappe/ERPNext lessons.
Read and dig into Scrawl screen captures, where someone recorded their screen while talking, clicking and drawing red marks on it. Use whenever a message contains a Scrawl capture (a line like `[scrawl 0:12 · App “Window” · /path/to/….scrawl]`, a `.scrawl` bundle path, or a contact-sheet.png from one), when the user says "look at my scrawl" or refers to something they just recorded or drew, or when you need the `scrawl` CLI to zoom into a moment, pull frames, send a capture to a session, or export one as video.
Codify the discipline-section guidance, the CSO description rule, and the size-budget checklist that easy-cheese skills follow when authoring or revising a skill. Use when writing a new skill or SKILL.md, adding a discipline section, or reviewing an existing skill against easy-cheese's authoring conventions.
Apifox API test cases: querying, creating, updating, deleting, categorizing and running test-case and test-data; handles test steps, assertions, variable extraction, pre- and post-processors, datasets, and issues such as "test steps created via the CLI do not show up in the frontend".
Manage entity status transitions in Basic Memory: archive completed work, move notes between status folders, update frontmatter, and handle edge cases. Use when marking items complete, archiving old entities, or managing any folder-based status workflow.
This skill should be used when the user asks to "analyze experimental results", "run strict statistical analysis", "compare model performance", "generate scientific figures", "check significance", "do ablation analysis", or mentions interpreting experiment data with rigorous statistics and visualization. It focuses on strict analysis bundles, not Results-section prose.
A deterministic thinking partner that challenges assumptions and applies mental models to sharpen decisions, solve problems, and think more clearly. Use this skill whenever a user says "help me think through X", "challenge my thinking", "what am I missing", "apply mental models to this", "play devil's advocate", "stress test this idea", "poke holes in my plan", "help me decide between X and Y", "what are the second-order effects", "I'm stuck on a decision", names any specific model (SWOT, first principles, inversion, pre-mortem, etc.), or asks for structured reasoning on any ambiguous, high-stakes, or complex problem. Also trigger when the user seems uncertain, is rationalizing, or is asking "am I thinking about this right?" Even casual phrases like "what do you think about..." on non-trivial topics should trigger this skill.
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.
