Operate the put.io CLI as a consumer for put.io authentication, files, downloads, transfers, cloud storage, and SDK calls exposed through the CLI. Use only for command-line interaction with put.io or when the user explicitly requests putio CLI. Do not use for unrelated CLIs, generic TypeScript or SDK work, browser-based put.io inspection, or development of the CLI repository itself.
Develop or review put.io end-user apps and shared frontend packages: UI, state, tests, docs, test harnesses, delivery, and frontend machine setup. Use in a put.io frontend repository or for put.io frontend conventions. Not for unrelated frontend work, browser-only put.io inspection, SDK or API client work, or putio CLI consumer operations; frontend test-harness auth setup stays in scope.
React and Next.js performance optimization guide from Vercel Engineering (70 rules in 8 categories). Use when writing, reviewing, or refactoring React/Next.js code to eliminate waterfalls, reduce bundle size, prevent re-renders, optimize Server Components, or fix performance bottlenecks. Triggers on data fetching, Promise.all, Suspense, useMemo, dynamic imports, bundle analysis, code-splitting, and rendering performance tasks.
Save and load timestamped reports. Keyword routing for fast lookup. Cron jobs save output as reports; the agent or user queries them by keyword. Includes the Actionability Gate: delivery-time link checks (Broken/Dead/Indirect/Missing) for briefings, meeting digests, and research reports.
Create dark cinematic SaaS/product motion videos in the Presenton-like "magic UI" style: black starfield stage, bottom purple glow, large kinetic type, cyan-to-magenta CTA buttons, prompt cards, floating UI templates, integration badges, model rings, export objects, speed-blur transitions, and short product capability arcs. Use when the user asks for "这种风格", "同款风格", dark SaaS promo, AI product demo, magic UI product video, or a style-level creation inspired by a reference video. Do not use for pixel-level or frame-accurate replication; use rn-replica-qc first for that.
Generate and validate Schema.org JSON-LD, and assess Google rich result eligibility where applicable. Supports FAQ, HowTo, Article, Product, LocalBusiness, and multi-type schemas. Use when asked to "add schema markup", "generate structured data", "JSON-LD", "rich snippets", "FAQ schema", "product markup", "add structured data to my page", "how to get rich snippets", or any structured data task.
Query a markdown tree with the sense CLI: filter notes by frontmatter, search prose, follow wikilinks and backlinks, trace link paths, find similar but unlinked notes, and inspect note outlines. Use when a task needs to query, filter, count, search, or report on a markdown directory; when a directory has sense.config.json; or when adding a saved sense query.
Customising the visual theme of an SGDS application—product brand colours, day/night mode, font, border radius, and spacing density. Use when users ask about changing the primary colour, theming their app, enabling dark mode, night mode, overriding CSS tokens, customising the font, compact/spacious density, or border radius. Apply this skill whenever theming, branding, density, or CSS token overrides are mentioned
ALWAYS use this skill when building UI with @govtechsg/sgds-web-component or when a user mentions SGDS or Singapore Design System—even if they don't explicitly ask for help. This is the mandatory entry point for all SGDS development: it guides you to the right skill for setup, components, utilities, forms, theming, page layouts, block templates, and data visualisation. Read this before writing any SGDS application code.
Expert guide for designing and building high-quality skills from scratch through structured conversation. Use when someone wants to create a new skill, build a skill, design a skill, or asks for help making Agents do something consistently. Also use when someone says “turn this into a skill”, “I want to automate this workflow”, “how do I teach my Agent to do X”, or mentions creating SKILL.md files. Covers standalone skills and MCP-enhanced workflows. Do NOT use for creating subagents (use subagent-creator) or technical design documents (use create-technical-design-doc).
Use when a session starts or resumes after compaction (auto via the session_start and session_compact event hooks) and the team AI directives context — constitution, CDR index, Class Boots catalog, skills registry — is not yet injected; also fires the session-end friction trigger for CDR/ADR/PDR capture with pending-decision safety nets.
Write, run, and analyze structured test suites for Agentforce agents. TRIGGER when the user writes or modifies test spec YAML (AiEvaluationDefinition); runs sf agent test create, run, run-eval, or results commands; asks about test coverage strategy, metric selection, or custom evaluations; interprets test results or diagnoses test failures; or asks about batch testing, regression suites, or CI/CD test integration. DO NOT TRIGGER when the user creates, modifies, previews, or debugs .agent files (use developing-agentforce); deploys or publishes agents; writes Agent Script code; uses sf agent preview for development iteration; analyzes production session traces (use observing-agentforce); or requests OWASP, security, or red-team testing (use securing-agentforce).
Add a custom in-app product tour (spotlight onboarding overlay) without a library (no joyride/intro.js/driver.js). Draw a dark layer with spotlight cutouts around elements selected by CSS selector, attach labeled tooltips, and place a “tap to close” pill in the largest empty space. Responsive on mobile and desktop, locks scrolling, measures with getBoundingClientRect, and closes on any click. Use when the user wants to “add a tour guide,” “onboarding tour,” “in-app guide,” “spotlight tour,” “product tour,” “walkthrough,” “bonbon-style tour,” or invokes /tour-guide. Suited to React/Next.js + Tailwind. Each route defines its own list of stops (spots); elements are marked with a stable data-tour attribute.
This skill analyzes meeting transcripts to extract decisions, action items, opinions, questions, and terminology using Cerebras AI (llama-3.3-70b). Use this skill when the user asks to analyze a transcript, extract action items from meetings, find decisions in conversations, build glossaries from discussions, or summarize key points from recorded meetings.
UI/UX design intelligence: a searchable local database of design styles, color palettes, font pairings, UX guidelines and chart types, plus stack-specific UI guidance for React, Next.js, Vue, Svelte, SwiftUI, React Native, Flutter, Tailwind, shadcn/ui and more. Ships with a Python search script.
Validates JSON data against JSON Schema using the z-schema library. Use when the user needs to validate JSON, check data against a schema, handle validation errors, use custom format validators, work with JSON Schema drafts 04 through 2020-12, set up z-schema in a project, compile schemas with cross-references, resolve remote $ref, configure validation options, or inspect error details. Covers sync/async modes, safe error handling, schema pre-compilation, remote references, TypeScript types, and browser/UMD usage.
Real-time web search and page reading using Aliyun IQS APIs. Use this skill FIRST when the user needs current information, news, facts verification, URL content extraction, or any web-based research. This skill provides structured search results with source links, markdown-formatted content extraction, and supports various search engines including real-time news search and deep research modes.
Expert API architect specializing in RESTful API design, GraphQL, gRPC, and API security. Deep expertise in OpenAPI 3.1, authentication patterns (OAuth2, JWT), rate limiting, pagination, and OWASP API Security Top 10. Use when designing scalable APIs, implementing API gateways, or securing API endpoints.
ASD-STE100 Simplified Technical English, and a reply structure a reader with ADHD can act on. A standing style rule, not an on-request tool. Layer 1 governs the words of every text a human reads — chat replies, docs, READMEs, commit messages, PR text, code comments, error messages, release notes, tool descriptions, task trackers, wiki pages. Layer 2 governs the order of a reply to a person — the next action first, numbered steps, no preamble and no closer. Neither layer touches code, identifiers, or command syntax. Load it before writing prose, and also when asked to remove “AI slop”, make writing clear or plain, enforce a controlled style, or review text for STE violations. Two word modes — strict (procedures, runbooks, safety text, error messages) and STE-flavored (general prose, the default).
Analyze uncertainty using Nassim Taleb-style tail risks, skin in the game, subtraction, the Lindy effect, and barbell strategies. Use to assess ruin risk, irreversible losses, fragility, agency problems, comparisons of old and new approaches, and resource allocation in investment, business, policy, career, product, or personal decisions.
Expert knowledge for Azure Database for PostgreSQL development including troubleshooting, best practices, decision making, architecture & design patterns, limits & quotas, security, configuration, integrations & coding patterns, and deployment. Use when using Flexible Server, pgvector/Apache AGE, Private Link/TLS, PITR/geo-restore, or PgBouncer pooling, and other Azure Database for PostgreSQL related development tasks. Not for Azure SQL Database (use azure-sql-database), Azure SQL Managed Instance (use azure-sql-managed-instance), SQL Server on Azure Virtual Machines (use azure-sql-virtual-machines), Azure Database for MySQL (use azure-database-mysql).
Step-by-step guide for setting up Better Auth authentication with Convex and TanStack Start. Use this skill when configuring authentication in a Convex + TanStack Start project, troubleshooting auth issues, or implementing sign up/sign in/sign out flows. Covers installation, environment variables, SSR authentication, route handlers, and the expectAuth pattern.
Turns plain-language chart design requests into exact Bklit UI (@bklit shadcn registry) components and props, styled to fit the host app. Use when someone describes how a chart should look rather than naming props, e.g. "diagonal pattern background that fades out", "squircle bars", "3D glass bars", "hatched area", "dot grid", "skeleton loading state", "dashed forecast", "half donut", "make the charts match my brand / dark mode / border radius". Detects the project's Tailwind version, colour format, dark-mode strategy, radius, and existing chart tokens, then picks a proven recipe, installs the right @bklit/<item>, adapts colours to theme tokens, and states honestly when Bklit has no prop for the request. Also use when theming or restyling Bklit charts.
Start a new Blockbench model or scene from a short intake form and deliver a render-ready Blender scene. Asks for quality, texture style (PBR 2K/HD/standard, vanilla Minecraft, classic Blockbench), animation (keyframed or Havok physics), scene type (scene, vignette, isometric room), subject, output folder and render preset; builds .bbmodel files with the headless Blockbench MCP server and parallel agents; imports them into Blender; and writes a render.cmd that renders stills on every GPU and assembles them into a video with FFmpeg. Use when the user runs /blockbench-new-model or asks for a new Blockbench model delivered as a rendered Blender scene or video.
Save and mutate workflow state — init a workflow, update fields, transition phases, and capture a structured handoff before context exhaustion. Use when the user says 'save progress', 'checkpoint', 'I need to stop', or runs /checkpoint. Writes current workflow phase, task progress, and artifacts to the event store for later resumption. Do NOT use for restoring/reading state after a session break (that is /rehydrate) or for workflow initialization framing handled by ideate/debug/refactor commands.

Creates a DevOps Center WorkItem to track a fix for a test failure or Code Analyzer violation. Before creating anything, it shows a subject/assignee/project preview and requires explicit confirmation. Use this skill when you want to create a fix work item, track a remediation task, or assign a test or analysis failure to a developer. TRIGGER when: the user wants to create a fix work item, log a remediation, or assign a failure to a developer for resolution. DO NOT TRIGGER when: writing the fix code itself (use generating-apex).
