laksh-star Bundle

Build, plan, or review a CopilotKit-powered UI around an existing workflow, backend, internal tool, or decision process. Use when Codex is asked to add CopilotKit to an app, turn backend state into a copilot-aware interface, register app context or frontend tools, design structured/generative UI surfaces, add human approval gates, validate a CopilotKit integration, or prepare a community-ready CopilotKit walkthrough or article from a real workflow.

dvy1987 Bundle

Design stable APIs and module boundaries — contract-first types, consistent errors, boundary validation, additive changes. Load when designing REST or GraphQL endpoints, public module interfaces, component props, or FE/BE contracts. Also triggers on "API design", "interface design", "design the API", "module boundary", "API contract", "define the interface". Complements feature-spec (product layer). Routes breaking retirement to api-deprecation-and-migration when it exists.

dvy1987 Bundle

Test and debug browser UIs using Chrome DevTools MCP — DOM inspection, console errors, network requests, performance traces, and visual verification. Load when building or debugging anything that renders in a browser, verifying a UI fix, profiling Core Web Vitals in a real page, or the user asks for browser testing with DevTools. Requires chrome-devtools MCP configured. Not for backend-only or CLI work. Pairs with frontend-design and performance-optimization.

dvy1987 Bundle

Content sanitization and hidden-content detection for agent skill security. Scans markdown, HTML, and text for visually hidden but agent-readable attacks: CSS-hidden text (display:none, color:white, font-size:0, opacity:0), HTML comments with instructions, collapsible details sections, zero-width unicode, homoglyphs, misleading links, and inline HTML in markdown. Enforces mandatory sanitization before external content enters agent context. Load as part of the secure-* sequence during any repo scan or skill audit. Also load for sanitize content, check hidden text, scan markdown attacks, strip HTML, detect invisible instructions, check zero-width chars. Core principle: visibility does not equal influence — hidden content is more dangerous than visible content because agents process it but humans cannot see it.

nathanonn Bundle

Push generated block markup, CSS and JS animation into a WordPress site over the core REST API, authenticated with an admin Application Password — no MCP server, no CLI, no SSH, curl only. Use when the user wants to push block markup to a WordPress page, send generated CSS to a WordPress site, ship an AI-designed page or landing page to WordPress over REST, add a GSAP or scroll animation to a WordPress site, run a PHP or JS snippet on a WordPress site over REST, install or activate a WordPress plugin over REST, set the static front page, update a page without copy-pasting into the block editor, or read and write the user global-styles record. Trigger on publish this design to my site, make this my front page, Code Snippets plugin, wp-json, /wp/v2/pages, /wp/v2/plugins, global-styles styles.css, code-snippets/v1, WordPress Application Password.

nathanonn Bundle

Prototype a WordPress or WooCommerce plugin from its written spec as a runnable offline browser simulation — admin screens, front-end surfaces, and the rules connecting them — so the spec can be evaluated as a product before any PHP is written. Use when asked to prototype or simulate a WP plugin, build a clickable or demoable version of one, or check whether plugin requirements hold together. A focused mode builds only named surfaces, for requests like "build me a working WordPress admin settings screen" or "show me what this settings tab would look like". Not for writing production plugin code, not for logic-only prototypes with no WordPress surface, and not for exploring visual variations of a single component.

nathanonn Bundle

Validate, diagnose, or repair standalone serialized WordPress Gutenberg block markup built from core blocks, using a pinned Node.js runtime. Use when the user explicitly asks to validate, check, lint, or debug block markup or `<!-- wp:... -->` block comments, reports an invalid block, "unexpected or invalid content", or an "Attempt Block Recovery" prompt, or is about to paste markup into the WordPress Code Editor or assign it to post_content. Scope is standalone, cross-site-portable core block markup only; site-specific, theme-specific, dynamic, plugin, and third-party block content are out of scope. Do not trigger merely because another skill emits block markup - prototype-wp (offline WP plugin prototypes), wp-spec-to-goal and wp-requirements-to-goals (Codex goal bundles), and pressbridge (pushing code, CSS, or blocks to a live remote WP site) own their own workflows.
