Professional Skills for Claude

Get grilled on your own plan, one question at a time, until every branch of the decision tree is actually resolved -- before an agent starts building it.

Navigate sites, fill forms, and extract data through natural-language instructions -- no selectors to write, no scripts to maintain.

Scaffold, compose, and extend shadcn/ui components with correct variants, accessibility patterns, and Tailwind classes — no more copy-paste guesswork.

Turn Claude into a full web-research worker: scrape any page, run deep crawls, monitor competitor sites, and synthesize findings — all without leaving the chat.

Generate a project-specific .cursorrules or CLAUDE.md file that locks in your stack conventions, naming rules, and off-limits patterns so Claude and Cursor code the way you want every time.

Apply Andrej Karpathy's four-rule coding discipline: think before you code, stay minimal, make surgical changes, and drive toward the goal — every session.

Audit any codebase against OWASP Top 10:2025 and ASVS 5.0 — injection, broken auth, SSRF, insecure deserialization, and 40+ more checks with file-level findings.

Write tests first, make them pass, then refactor — a strict Red-Green-Refactor loop with typed stubs, coverage gates, and the Matt Pocock / Kent Beck discipline.

Get an expert design critique of any UI in seconds — spacing, hierarchy, contrast, and accessibility — with concrete, copy-pasteable fixes.

Audit your Next.js app for App Router pitfalls, Server/Client boundary bugs, caching mistakes, and bundle bloat — with file-level fixes.

Point it at a repo and get a new-hire-ready onboarding doc -- architecture overview, key entry points, and a suggested first-week reading order.

Trace an MCP client-server handshake and tool call end to end -- catch schema mismatches, silent failures, and missing capabilities before they reach production.

Never mark a task done on a guess: runs the actual command, checks the actual output, and only reports success once it has evidence.

Get a senior engineer's code review on any PR diff — bugs, logic errors, security issues, test gaps, and style notes — with inline comment format ready to paste.

Get a plain-language read on your codebase's architecture -- module boundaries, coupling hot spots, and where structure is fighting your next feature.

Point it at an API's docs or OpenAPI spec and get a typed client, auth handling, retries, and example calls — wired and ready.

Generate robust Playwright end-to-end tests from a URL or user story — resilient selectors, fixtures, and CI config included.
