Claude Skills for Freelance Web Developers: 10 SKILL.md Files for Claude Code, Claude.ai & Cursor
by CoreCodify
$29
10 ready-to-install Claude Skills that handle the repeatable parts of freelance web work: briefs, quotes, QA, SEO, accessibility, speed, code review, bug triage and client handover. Install them once, and Claude follows the same careful process on every project.
Each skill is a real SKILL.md folder built to the open Agent Skills standard, so the same files work in Claude Code, Claude.ai (web and desktop) and Cursor.
The 10 skills
client-brief-to-spec: turns a messy client brief, call notes or a WhatsApp thread into a scoped spec with acceptance criteria and the questions to ask next.
project-quote-writer: estimates hours task by task and builds 3 packages, payment milestones, assumptions, exclusions and a proposal (works for Upwork and Fiverr too).
nextjs-project-conventions: Next.js 16 App Router conventions (proxy.ts, async params, caching, metadata) plus a pre-deploy checklist.
landing-page-qa: a pre-launch QA pass covering content, forms, links, responsive layout, meta tags and tracking, with a prioritised fix list.
technical-seo-audit: crawlability, indexing, canonicals, structured data and Core Web Vitals, written up as a client-ready report.
accessibility-pass: a WCAG 2.2 AA review with the new 2.2 criteria and fixes for common components.
performance-pass: finds what hurts LCP, INP and CLS and gives fixes in order of impact.
client-code-review: reviews code for security, correctness, maintainability and handover readiness before it reaches the client.
bug-triage: turns a vague client complaint into a reproducible ticket, a severity rating and a calm client reply.
client-handover-docs: a site guide, an access inventory and a care-plan offer, so a project closes cleanly and turns into retainer work.
