When the user wants help with paid advertising campaigns on Google Ads, Meta (Facebook/Instagram), LinkedIn, Twitter/X, or other ad platforms. 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
