Claude Skills by KevinZai

CEO/founder-mode plan review. Rethink the problem, find the 10-star product, challenge premises, expand scope when it creates a better product. Four modes: SCOPE EXPANSION (dream big), SELECTIVE EXPANSION (hold scope + cherry-pick expansions), HOLD SCOPE (maximum rigor), SCOPE REDUCTION (strip to essentials). Use when asked to "think bigger", "expand scope", "strategy review", "rethink this", or "is this ambitious enough". Proactively suggest when the user is questioning scope or ambition of ...

Review a UI/UX plan with a designer's eye. Rates each design dimension 0-10, explains what makes it a 10, then fixes the plan. Use when: 'review the design plan', 'design critique'.

Eng manager-mode plan review. Lock in the execution plan — architecture, data flow, diagrams, edge cases, test coverage, performance. Walks through issues interactively with opinionated recommendations. Use when asked to "review the architecture", "engineering review", or "lock in the plan". Proactively suggest when the user has a plan or design doc and is about to start coding — to catch architecture issues before implementation.

Connect to The Playground — a virtual social space where AI agents can meet, chat, and explore together. Use when the user wants their bot to socialize with other bots, visit The Playground, explore virtual rooms, or chat with other AI agents in a shared space.

Automate PostHog tasks via Rube MCP (Composio): events, feature flags, projects, user profiles, annotations. Always search tools first for current schemas.

Agile product ownership for backlog management and sprint execution. Covers user story writing, acceptance criteria, sprint planning, and velocity tracking. Use for writing user stories, creating acceptance criteria, planning sprints, estimating story points, breaking down epics, or prioritizing backlog.

Pythonic idioms, PEP 8 standards, type hints, and best practices for building robust, efficient, and maintainable Python applications.

Real-time application architecture — WebSocket, SSE, pub/sub, presence, and collaborative editing patterns

Use when receiving code review feedback, before implementing suggestions, especially if feedback seems unclear or technically questionable - requires technical rigor and verification, not performative agreement or blind implementation

Redis patterns — data structures, caching strategies, pub/sub, rate limiting, session management, and operational best practices.

You are an expert in viral growth and referral marketing with access to referral program data and third-party tools. Your goal is to help design and optimize programs that turn customers into growth engines.

Best practices for Remotion - Video creation in React

Generate walkthrough videos from Stitch projects using Remotion with smooth transitions, zooming, and text overlays

Use when completing tasks, implementing major features, or before merging to verify work meets requirements

Weekly engineering retrospective. Analyzes commit history, work patterns, and code quality metrics with persistent history and trend tracking. Team-aware: breaks down per-person contributions with praise and growth areas. Use when asked to "weekly retro", "what did we ship", or "engineering retrospective". Proactively suggest at the end of a work week or sprint.

Pre-landing PR review. Analyzes diff against the base branch for SQL safety, LLM trust boundary violations, conditional side effects, and other structural issues. Use when asked to "review this PR", "code review", "pre-landing review", or "check my diff". Proactively suggest when the user is about to merge or land code changes.

When the user wants help with revenue operations, lead lifecycle management, or marketing-to-sales handoff processes. Also use when the user mentions 'RevOps,' 'revenue operations,' 'lead scoring,' 'lead routing,' 'MQL,' 'SQL,' 'pipeline stages,' 'deal desk,' 'CRM automation,' 'marketing-to-sales handoff,' 'data hygiene,' 'leads aren't getting to sales,' 'pipeline management,' 'lead qualification,' or 'when should marketing hand off to sales.' Use this for anything involving the systems and p...

Docker-based isolated sessions for YOLO mode with resource limits

When the user wants to create sales collateral, pitch decks, one-pagers, objection handling docs, or demo scripts. Also use when the user mentions 'sales deck,' 'pitch deck,' 'one-pager,' 'leave-behind,' 'objection handling,' 'deal-specific ROI analysis,' 'demo script,' 'talk track,' 'sales playbook,' 'proposal template,' 'buyer persona card,' 'help my sales team,' 'sales materials,' or 'what should I give my sales reps.' Use this for any document or asset that helps a sales team close deals....

Self-healing system patterns — circuit breakers, auto-restart, error budgets, graceful degradation, and auto-recovery

Automate SendGrid email operations including sending emails, managing contacts/lists, sender identities, templates, and analytics via Rube MCP (Composio). Always search tools first for current sche...

Designs and implements backend systems including REST APIs, microservices, database architectures, authentication flows, and security hardening. Use when the user asks to "design REST APIs", "optimize database queries", "implement authentication", "build microservices", "review backend code", "set up GraphQL", "handle database migrations", or "load test APIs". Covers Node.js/Express/Fastify development, PostgreSQL optimization, API security, and backend architecture patterns.

Automate Sentry tasks via Rube MCP (Composio): manage issues/events, configure alerts, track releases, monitor projects and teams. Always search tools first for current schemas.

Compress the current session into a dense, reloadable summary. Extracts key decisions, files modified, lessons learned, and open questions. Saves to ~/.claude/sessions/compressed/. Designed for loading at next session start to restore context without full transcript replay.

Auto-run at the start of every Claude Code session. Loads project context, checks for active tasks, connects MCP servers, and suggests the right skill for the current workflow phase. This is the "boot sequence" that ensures every session starts with maximum context and minimum waste. Trigger: Run at session start or when switching projects.

Import cookies from your real browser (Comet, Chrome, Arc, Brave, Edge) into the headless browse session. Opens an interactive picker UI where you select which cookie domains to import. Use before QA testing authenticated pages. Use when asked to "import cookies", "login to the site", or "authenticate the browser".

Configure deployment settings for /land-and-deploy. Detects your deploy platform (Fly.io, Render, Vercel, Netlify, Heroku, GitHub Actions, custom), production URL, health check endpoints, and deploy status commands. Writes the configuration to CLAUDE.md so all future deploys are automatic. Use when: "setup deploy", "configure deployment", "set up land-and-deploy", "how do I deploy with gstack", "add deploy config".

Ship workflow: detect + merge base branch, run tests, review diff, bump VERSION, update CHANGELOG, commit, push, create PR. Use when asked to "ship", "deploy", "push to main", "create a PR", or "merge and push". Proactively suggest when the user says code is ready or asks about deploying.

Self-evolving skills — analyzes session corrections, error patterns, and successful approaches to automatically propose improvements to SKILL.md files. Use when the user says 'evolve skills', 'improve skills from history', 'what have we learned'.

Structured spec interview for new features and projects. Asks 5-7 targeted questions using AskUserQuestion, then generates a formatted spec document. Use for ANY feature that will take more than 1 day of work. Always run in a SEPARATE session from execution. Based on Thariq Shihipar's (Claude Code lead) highest-leverage workflow.

Send progress updates to Discord, Slack, or email at configurable intervals during long-running sessions

Suggests manual context compaction at logical intervals to preserve context through task phases rather than arbitrary auto-compaction.
