deliverable-criteria_skill

Overview

This skill codifies quality gates and acceptance criteria for Next.js 15 App Router projects to ensure deployable, performant, accessible, and secure deliveries. It provides a structured pre-deployment checklist, functional verifications, performance targets, and operational requirements for production readiness. Use it to standardize sign-off across engineering, QA, security, and product teams.

How this skill works

The skill organizes checks into areas: compilation, linting, testing, functionality (routing, data fetching, interactivity), performance, accessibility, SEO, security, mobile, browser compatibility, error handling, monitoring, and deployment. Each area lists concrete criteria, verification steps, commands to run, and pass/fail acceptance rules. Teams follow the checklist, run the specified audits and tests, and mark items for final sign-off and release readiness.

When to use it

• Before running a production build or creating a release candidate
• During release readiness reviews and QA sign-off meetings
• When onboarding a new Next.js app or migrating to App Router
• For performance, accessibility, or security audits prior to launch
• When documenting deployment and rollback procedures

Best practices

• Automate checks in CI: build, type-check, lint, tests, and bundle analysis
• Keep strict thresholds for Core Web Vitals and test on throttled networks
• Enforce ESLint/Prettier rules with CI gating and justify any disabled rules
• Run E2E tests for navigation, forms, and critical paths; require coverage minimums
• Use secure storage for secrets, set security headers, and validate API inputs

Example use cases

• Pre-release pipeline that fails CI on TypeScript, lint, or test errors
• Sprint completion criteria where accessibility and performance audits are mandatory
• Security review checklist for protected routes, JWT handling, and headers
• Performance optimization task using bundle-analyzer and Lighthouse targets
• Production readiness playbook including monitoring, health checks, and rollback steps
