Also use when the user mentions 'PPC,' 'paid media,' 'ROAS,' 'CPA,' 'ad campaign,' 'retargeting,' 'audience targeting,' 'Google Ads,' 'Facebook ads,' 'LinkedIn ads,' 'ad budget,' 'cost per click,' 'ad spend,' or 'should I run ads.' Use this for campaign strategy, audience targeting, bidding, and optimization. For bulk ad creative generation and iteration, see ad-creative. For landing page optimization, see cro.

Persistent engineering knowledge vault with semantic search. Save decisions, patterns, debug solutions, and insights as Zettelkasten notes in Obsidian with automatic embedding indexing for semantic retrieval. Use this skill whenever the user says "/memo", "запомни это", "сохрани в базу", "save this", "remember this", "добавь в базу знаний", "log this pattern", or any variation of wanting to persist knowledge. Also trigger for "/memo find", "/memo search", "что я решал по X", "find in vault", "search vault", "найди в базе" to search notes — both keyword and semantic. Trigger for "/memo dedup", "/memo stats", "/memo project", "/memo reindex". This is the bridge between Claude Code sessions and long-term engineering memory across all projects.

Use when starting any new task to select the right GSD mode (fast/quick/plan-phase) and the right model tier (Haiku/Sonnet/Opus) for subagents — prevents 5-10× cost overpay on routine work

Pack the whole repo (or a remote one) into one AI-friendly file via Repomix. Use for architectural reviews, cross-repo handoff, full-codebase audits — not for single-file lookups. Triggers on "pack repo", "feed codebase to AI", "снапшот", "analyze remote repo".

Use BEFORE coding any new feature, MVP, pricing/billing change, launch, or pivot. Acts as a product validation gate for solo founders — validates target user, JTBD, pain intensity, current alternative, success metric, distribution channel, structural advantage vs competitors, unit economics with SaaS-graveyard gate, cheapest experiment, and top risk. RIGID — do not proceed to technical planning until product context is documented in `.planning/product/<slug>.md` or risk is explicitly accepted. Triggers on "build", "ship", "add feature", "MVP", "launch", "pivot", "pricing", "billing", before /plan, /tdd, /gsd-plan-phase, /gsd-discuss-phase, or when user describes a feature without naming a measurable success metric.

Use this skill to query your Google NotebookLM notebooks directly from Claude Code for source-grounded, citation-backed answers from Gemini. Browser automation, library management, persistent auth. Drastically reduced hallucinations through document-only responses.

Use before declaring work complete on business-critical phases — simulate a Senior practitioner (auth specialist, payment engineer, DBA, security auditor) reviewing the change with their failure-mode bias

Use when user requests work via natural language ("fix this", "add feature X") — selects appropriate GSD command (gsd-fast / gsd-quick / gsd-plan-phase) based on risk and scope, prevents using heavyweight pipeline for trivial work

Use after deploying a phase to production, when integrating new external services, or when user-facing behavior changes — instruments runtime errors (Sentry), user funnels (Posthog), and pre-ship smoke (Playwright)

Use after `/gsd-ship` to verify product behaves correctly in production — runs Playwright e2e against deployed URL, checks Sentry for new errors, validates Posthog conversion funnel

REST API design patterns — naming, status codes, OpenAPI/Swagger, versioning. Triggers on api/endpoint/openapi/swagger keywords.

Supreme Council integration with GSD plan/execute and audit workflows; verdict-handling rules (PROCEED/SIMPLIFY/RETHINK/SKIP)

When the user wants to set up, improve, or audit analytics tracking and measurement. Also use when the user mentions "set up tracking," "GA4," "Google Analytics," "conversion tracking," "event tracking," "UTM parameters," "tag manager," "GTM," "analytics implementation," "tracking plan," "how do I measure this," "track conversions," "attribution," "Mixpanel," "Segment," "are my events firing," or "analytics isn't working." Use this whenever someone asks how to know if something is working or wants to measure marketing results. For A/B test measurement, see ab-test-setup.

Expert guidelines for Chrome extension development with Manifest V3, covering security, performance, and best practices

Use this skill whenever the user wants to create, read, edit, or manipulate Word documents (.docx files). Triggers include: any mention of 'Word doc', 'word document', '.docx', or requests to produce professional documents with formatting like tables of contents, headings, page numbers, or letterheads. Also use when extracting or reorganizing content from .docx files, inserting or replacing images in documents, performing find-and-replace in Word files, working with tracked changes or comments, or converting content into a polished Word document. If the user asks for a 'report', 'memo', 'letter', 'template', or similar deliverable as a Word or .docx file, use this skill. Do NOT use for PDFs, spreadsheets, Google Docs, or general coding tasks unrelated to document generation.

Helps users discover and install agent skills when they ask questions like "how do I do X", "find a skill for X", "is there a skill that can...", or express interest in extending capabilities. This skill should be used when the user is looking for functionality that might exist as an installable skill.

Search, scrape, and interact with the web via the Firecrawl CLI. Use this skill whenever the user wants to search the web, find articles, research a topic, look something up online, scrape a webpage, grab content from a URL, get data from a website, crawl documentation, download a site, or interact with pages that need clicks or logins. Also use when they say "fetch this page", "pull the content from", "get the page at https://", or reference external websites. This provides real-time web search with full page content and interact capabilities — beyond what Claude can do natively with built-in tools. Do NOT trigger for local file operations, git commands, deployments, or code editing tasks.

Internationalization and localization patterns. Detecting hardcoded strings, managing translations, locale files, RTL support.

Next.js best practices - file conventions, RSC boundaries, data patterns, async APIs, metadata, error handling, route handlers, image/font optimization, bundling

Use this skill whenever the user wants to do anything with PDF files. This includes reading or extracting text/tables from PDFs, combining or merging multiple PDFs into one, splitting PDFs apart, rotating pages, adding watermarks, creating new PDFs, filling PDF forms, encrypting/decrypting PDFs, extracting images, and OCR on scanned PDFs to make them searchable. If the user mentions a .pdf file or asks to produce one, use this skill.

Use when working with the Resend email API — sending transactional emails (single or batch), receiving inbound emails via webhooks, managing email templates, tracking delivery events, managing domains, contacts, broadcasts, webhooks, API keys, automations, events, viewing API request logs, or setting up the Resend SDK. Always use this skill when the user mentions Resend, even for simple tasks like "send an email with Resend" — the skill contains critical gotchas (idempotency keys, webhook verification, template variable syntax) that prevent common production issues.

Manages shadcn components and projects — adding, searching, fixing, debugging, styling, and composing UI. Provides project context, component docs, and usage examples. Applies when working with shadcn/ui, component registries, presets, --preset codes, or any project with a components.json file. Also triggers for "shadcn init", "create an app with --preset", or "switch to --preset".

Guides Stripe integration decisions — API selection (Checkout Sessions vs PaymentIntents), Connect platform setup (Accounts v2, controller properties), billing/subscriptions, Treasury financial accounts, integration surfaces (Checkout, Payment Element), migrating from deprecated Stripe APIs, and security best practices (API key management, restricted keys, webhooks, OAuth). Use when building, modifying, or reviewing any Stripe integration — including accepting payments, building marketplaces, integrating Stripe, processing payments, setting up subscriptions, creating connected accounts, or implementing secure key handling.
