Design exploration using parallel agents through a 7-phase process: topic analysis, memory context, divergent ideation (10+ ideas), feasibility filtering, evaluation with devil's advocate scoring (0-10 across 7 dimensions), synthesis of top approaches, and…

Chain patterns for multi-phase pipelines: MCP detection, handoff files, checkpoint-resume, worktree agents, CronCreate monitoring. Use when building or debugging a pipeline skill.

Generate tests that do not exist yet. Analyzes coverage gaps, then writes and runs new test files across three tiers (unit, integration via testcontainers, Playwright E2E), one test-generator agent per tier, healing failures for up to 3 iterations. Use when…

Fixes GitHub issues using parallel analysis agents for root cause investigation, code exploration, and regression detection. Reads issue context from gh CLI, searches codebase and memory for related patterns, generates a fix with tests, and links the…

Full-power feature implementation using parallel subagents for backend, frontend, testing, and security, with worktree isolation and quality verification in one workflow. Chains with /ork:cover for tests and /ork:verify for validation. Use when asked to…

PR review using parallel specialized agents for code quality, security, testing, architecture, and performance analysis. Synthesizes findings into a review report with conventional comments (praise/issue/suggestion/nitpick) and approve or request-changes…

Security patterns for authentication, defense-in-depth, input validation, OWASP Top 10, LLM safety, and PII masking. Use when implementing auth flows, security layers, input sanitization, vulnerability prevention, prompt injection defense, or data redaction.

Cross-repo migration swarm — one coordinator + N parallel subagents (one per target repo) that apply the same transformation, open PRs, wait for CI, and report back to a shared JSON ledger. Coordinator handles topology, conflict auto-rebase, and…

Create beautiful ASCII art visualizations for plans, architectures, workflows, and data

Use when creating or developing anything, before writing code or implementation plans - refines rough ideas into fully-formed designs through structured Socratic questioning, alternative exploration, and incremental validation

Capture content from JavaScript-rendered pages, login-protected sites, and multi-page documentation using Playwright MCP tools or Claude Chrome extension. Use when WebFetch fails on SPAs, dynamic content, or auth-required pages.

Use this skill when designing database schemas for relational (SQL) or document (NoSQL) databases. Provides normalization guidelines, indexing strategies, migration patterns, and performance optimization techniques. Ensures scalable, maintainable, and…

Use this skill when creating or evolving design systems for applications. Provides design token structures, component architecture patterns, documentation templates, and accessibility guidelines. Ensures consistent, scalable, and accessible UI design across…

Render a fixed status board for one client from the files in clients/NAME/ (profile, state log, post-call docs, cheatsheets, outreach, notes), the client's row in an optional CRM export, and Wispr Flow meeting titles when that MCP server is connected. The…

Turn one client call into a reviewed document with the call facts, a short recap message and a one-page scope, drafted in the client's language (Hebrew by default). Use right after a call when a text transcript exists (a file, or a Wispr Flow meeting through…

Build a one-page cheatsheet for the next call with a client from what the client folder already holds. Who they are, where things stand, the open threads, two to four goals for the call, the questions to ask, what to say when they push on price, timing or…

Record the outcome of a reviewed post-call document in the client's local state, from one confirmation and a visible diff. Computes one new entry for clients/NAME/state.md and, when the call carried a stage signal, a change to the single stage line in…

Analyze ETFs — holdings composition, sector and geographic exposure, expense ratio, and index-tracking error. Use when the user asks about an ETF ticker (SPY, QQQ, VTI, etc.), wants to compare two ETFs, check overlap between funds, or understand what an ETF…

Analyze US and global stocks (NASDAQ, NYSE, S&P 500 constituents) with technical, fundamental, and sentiment signals. Use when the user asks about international stocks, tickers like AAPL/NVDA/MSFT, S&P 500 or NASDAQ names, or wants RSI/MACD/moving-average or…

Screen the S&P 500 and NASDAQ-100 universe by technical and fundamental criteria to surface candidate stocks. Use when the user wants to filter or rank US stocks — 'S&P 500 names with RSI below 30', 'NASDAQ stocks above their 200-day average',…

Query the public yonyon.ai agent API from the command line or over MCP. Use when a user asks about Yonatan Gross, his work, projects, services, availability or fit; when they want the portfolio project list; when they want to book an intro call; or when they…
