app-builders-club Bundle

Visual QA gate for frontend code. ALWAYS use before delivering any UI changes - navigate, screenshot, verify console is error-free. Use for: responsive testing across viewports, form/interaction testing, debugging hydration and render issues. Catches visual bugs before users see them.

app-builders-club Bundle

Structured reasoning harness for problems where shallow thinking fails or hallucination is costly. Use whenever a question requires multi-step reasoning, involves competing hypotheses, has multiple interacting components, or carries irreversible consequences. Activate for debugging with unclear root causes, intermittent or multi-component issues, incident post-mortems, choosing between multiple valid approaches, architecture or design tradeoffs, causal chain analysis, high-stakes decisions, and any task where the first plausible answer is suspiciously easy. Provides reasoning modes (abductive, counterfactual, first-principles, inversion, and more), grounding techniques against confabulation, adversarial self-checks, root-cause playbooks, and automatic multi-approach synthesis (independent angles run in parallel and compared) — all through the sequential-thinking MCP tool. Skip for trivial lookups, obvious fixes, and single-step questions.

pandelisz Bundle

A Canvas is a live React app rendered beside the chat. You MUST use a canvas when the agent produces a standalone analytical artifact — quantitative analyses, billing investigations, security audits, architecture reviews, data-heavy content, timelines, charts, tables, interactive explorations, repeatable tools, or any response that benefits from visual layout. Especially prefer a canvas when presenting results from MCP tools (Datadog, Databricks, Linear, Sentry, Slack, etc.) where the data is the deliverable — render it in a rich canvas rather than dumping it into a markdown table or code block. If you catch yourself about to write a markdown table, stop and use a canvas instead. You MUST also read this skill whenever you create, edit, or debug any .canvas.tsx file.

geoly-ai Bundle

Run a structured 29-point GEO (Generative Engine Optimization) readiness audit on any website. Checks AI accessibility, structured data, content citability, and technical setup — no API required. Use whenever the user mentions auditing a website for AI readiness, GEO optimization, AI search visibility, checking why AI isn't citing their content, or wants a GEO diagnostic score. Also trigger for requests about llms.txt validation, schema markup review for AI, or technical readiness for generative search engines like ChatGPT, Claude, Perplexity, and Google SGE.

geoly-ai Bundle

Real-time GEO metrics monitoring and alerting orchestrator. Use this skill whenever the user wants to track, visualize, and react to AI GEO performance metrics over time — especially AIGVR (AI-generated visibility rate), SoM (Share of Model), AI citation volume, and related indicators across ChatGPT, Perplexity, Gemini, Claude, SGE, and other generative engines. Prefer this skill whenever the request goes beyond a static report and instead focuses on ongoing dashboards, time-series tracking, anomaly detection (sudden spikes/drops), or building an internal “GEO metrics command center.” It is designed to complement `geo-report-builder` by turning one-off analyses into a continuous monitoring system.
