Converts and transcodes audio file formats and encoding parameters using Volcengine LAS. Audio format conversion between wav, mp3, flac, m4a, ogg, aac and other audio formats. Adjusts sample rate (resample, downsample, upsample), bit rate (bitrate), channels (mono, stereo, channel mixing), audio compression, and audio quality settings via ffmpeg parameters. Supports TOS cloud storage paths and local file upload. Use this skill when the user wants to convert audio format (wav/mp3/flac/m4a/ogg/aac), transcode or re-encode audio files, adjust audio sample rate, bitrate, channels, compress audio files, resample or downsample audio, prepare audio for downstream tasks, or do any audio preprocessing.
Guides developers through integrating and using Viking SDK, covering installation, authentication, API calls, and troubleshooting for the Viking vector database, knowledge base, and memory store. Use when users need to develop business code with Viking SDK or ask questions about Viking.
Entrypoint for managing Volcengine Flink (based on Apache Flink) workloads. Use it for developing and deploying streaming and batch jobs, diagnosing real-time issues (e.g., backpressure, checkpoint failures, OOM), troubleshooting resources, and performing SRE actions (stop/start/restart/scale/config changes). It intelligently routes requests to four specialized sub-skills and leverages flink-mcp for tool execution.
Opt-in CanAI MCP power tool that can publish site PHP: FluentSnippets (create/update/publish PHP/CSS/JS snippets). Not for routine template/page/content work — use canai-mcp for that. Triggers on: "/canai-yolo", "canai-yolo", "fluentsnippets", "fluent snippets", "easy-code-manager", "code snippet", "php snippet", "publish snippet", "create snippet".
This skill should be used when content teaches patterns (skills, subagents, ADRs, PHRs, specifications) that have canonical sources elsewhere. Prevents format drift by ensuring content references and follows the authoritative format from canonical sources. Use before implementing lessons that teach platform patterns, or when reviewing content for format consistency.
Create beautiful visual art in .png and .pdf documents using design philosophy. You should use this skill when the user asks to create a poster, piece of art, design, or other static piece. Create original visual designs, never copying existing artists' work to avoid copyright violations.
Manage the lifecycle of multi-tenant SAP CAP applications on Kubernetes using CAP Operator custom resources (CAPApplication, CAPApplicationVersion, CAPTenant, Domain, ClusterDomain). Use when deploying, upgrading, configuring domains, rotating credentials, troubleshooting CAP Operator-managed apps, or generating Helm charts with the CAP Operator Plugin.
Turns a finished client project into a publishable case study in the canonical 12-section Case Study Kit structure: SME interview questionnaire → data collection → result-first narrative (snapshot → 3-type Challenge → 1:1 Solution → before→after Results → testimonial → CTA → SEO), plus a designer visual brief and a pre-launch checklist. Also outputs 3 derivative formats (website page, one-pager PDF outline, LinkedIn handoff). Built for B2B service companies (agencies, outsourcing, consulting). Use when the user says: "напиши кейс", "зроби case study", "оформи проєкт у кейс", "case study from this project", "перепиши кейс", "у нас є результат — треба кейс", or pastes project notes / a call transcript / an old case and asks to turn it into a proper case study. NOT for collecting testimonials or reviews (that is a separate outreach ask) and NOT for writing LinkedIn posts from scratch (use linkedin-post-writing; this skill only hands off a post-ready summary).
End-to-end champion/buyer/user job change signal composite. Takes a set of known people (past buyers, champions, power users), detects when they move to a new company, researches the new company for ICP fit, and drafts personalized outreach leveraging the existing relationship. Tool-agnostic — works with any people source, detection method, and outreach platform.
Track product champions for job changes and qualify their new companies against ICP. Takes a CSV of known champions (with LinkedIn URLs), creates a baseline snapshot via Apify enrichment, then detects when champions move to new companies. Scores new companies on a 0-4 ICP fit scale. Outputs a downloadable CSV of movers with qualification verdicts.
Create a structured change management plan for any organisational change. Use when asked to write a change management plan, manage a change initiative, plan a system rollout, or lead an organisational transformation. Produces a plan covering stakeholder analysis, impact assessment, communication strategy, and resistance management.

Moves each step of an agent skill whose correct result is fixed by its inputs into a script the skill runs, leaving the model only judgment. Use when the user says "script the deterministic steps", or when creating a skill, or adding or changing its steps, commands, or parsing. Not for trimming a skill; use cutting-skills.

Given a Chrome Releases blog post URL (chromereleases.googleblog.com), extract every CVE/bug and find the underlying Gerrit CL that fixed it by searching the local Chromium checkout and sub-repos. Use when asked to map Chrome security release notes to fixing CLs, or to find which commits correspond to CVEs in a Chrome stable update.
Scan support tickets, Slack channels, NPS scores, and usage patterns to flag accounts showing early churn indicators. Produces a weekly risk scorecard with severity tiers, root cause hypotheses, and suggested save plays per account. Designed for seed/Series A teams where the founder or a single CSM manages all accounts manually.
Update, upgrade, or migrate an existing CKEditor 5 integration to the latest or a specific version. Use it to bump the editor version, apply the breaking changes between two versions, move off a legacy installation method (predefined builds, webpack source imports, DLL builds, the old CDN), or fix errors that an update or mismatched CKEditor package versions caused. Do not use it to add CKEditor 5 to a new project, to write custom plugins, for downgrades, or for CKEditor 4.

You are a documentation expert specializing in creating comprehensive, maintainable documentation from code. Generate API docs, architecture diagrams, user guides, and technical references using AI-powered analysis and industry best practices.
(NS) Senior technical investigation, debugging, and root cause analysis from errors, logs, stack traces, failing tests, CI failures, or unexpected behavior. Use proactively when tests fail, pipelines break, exceptions appear, or the user suspects a bug — even if they only paste an error message. Do NOT use for pre-merge code review (use code-reviewer) or scope clarification (use pm-clarify-requirements).
Review Git changes for concrete defects and evidence-backed maintainability concerns. Use for code review of commits, ranges, staged changes, uncommitted changes, or selected files. With no target, review all staged, unstaged, and untracked changes; ask for a target if none exist. Trace behavior in the selected version, challenge suspected defects, exclude style-only preferences, and provide an approval verdict only when requested.
Use this skill whenever the user asks for a code review, package review, or architectural audit. Delivers severity-ranked findings with evidence and fixes, not general advice. Always saves the review as a markdown file and returns a concise summary in chat.
End-to-end, self-contained Python/TypeScript workflow that maps and audits a whole repo, then recursively deepens modules. Use to improve or modernize a codebase, reduce technical debt, make this more testable, find refactoring opportunities, deepen shallow modules, consolidate tightly-coupled modules, make codebase AI-navigable, or run a full-repo audit. Worker delegation is optional and human-gated.
Use when types become extremely complex. Use when types mirror external schemas. Use when maintaining type-to-schema mappings. Use when types require extensive type-level logic. Use when types drift from data sources.
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.
