High-performance browser-based text layout and measurement for virtualization, canvas, and layout-heavy applications.

Automated test generation with edge case analysis and framework-native syntax for TS, Python, Go, and Rust.

Idiomatic code translation between Python, TypeScript, and Go that preserves logic and adapts language-specific patterns.

Three-pass automated code review that catches error handling gaps, structural issues, and naming problems — then auto-fixes everything before code reaches the user.

by servrox

Free

Supercharge repo exploration and refactoring with semantic call-graph tracing and structural AST pattern matching.

Automatically transform JSON files or raw strings into production-ready TypeScript interfaces or Python dataclasses.

Auth & Multi Tenant SaaS Foundation

by PubsProToolkit

$29

Scaffold a complete, production-ready auth and multi-tenant foundation — sessions, OAuth/SSO, role-based access control, organizations, teams, invitations, and row-level data isolation — wired to your app and database.

lsp guided coding

by Roy Yuen

$5

Supercharge your agent with semantic code intelligence for safer refactors, precise navigation, and zero-error edits.

🧪 Webapp Tester

by JustHandled Labs

$15

Run real Playwright E2E tests on your web app: login, checkout, and form flows across desktop and mobile viewports, with screenshots, traces, and console logs captured on every failure. Catches broken flows and UI regressions before release, and tells you the likely fix, not just that something broke.

🧹 Code Comment Cleaner

by JustHandled Labs

$5

Preview code-like comment blocks across JavaScript, TypeScript, Python, Java, Go, Rust, HTML, and CSS. Preservation rules run before candidate detection; confirmed cleanups create .bak backups and remove only reviewed ranges.

Use this skill when the user is facing a bug in an Angular application, including issues with components, services, RxJS, HTTP calls, tests, or unexpected behavior.

🕸️ Codebase Graph

by JustHandled Labs

$25

Map any repo into an interactive D3 dependency graph plus a Markdown onboarding guide: entry points, module relationships, circular dependencies, and dead-code candidates, with refactor suggestions. Parses TypeScript, Python, Java, Go, and Rust imports, exports, and calls. Self-contained HTML, no source changes.

Professional audit tool to detect and fix React hooks anti-patterns, stale closures, and performance bottlenecks.

nextjs app router audit

by Sion Coolwijk

Free

Deep audit toolkit for Next.js App Router to fix performance waterfalls, SEO errors, and client boundary leaks.

🗺️ Change Impact Mapper

by JustHandled Labs

$13

Map the blast radius of a code change before you run the whole suite. For the files and functions you changed, it lists what imports or calls them, which tests cover them, flags any change with no covering test, and warns when a file has a lot of dependents. It tells an agent what its edit might break instead of making it guess. Resolves Python and JavaScript/TypeScript.

🧪 Test Quality Auditor

by JustHandled Labs

$15

Find the unit tests that pass without testing anything. Flags tests with no assertions, trivial existence-only checks (toBeDefined, assertIsNotNone), tests that assert the exact value they just mocked, snapshot-only tests, tautological assertions (expect(true).toBe(true)), empty placeholders, and over-mocked tests with more setup than assertions. Works on Jest/Vitest and pytest/unittest.

▲ Vercel Build Log Doctor

by JustHandled Labs

$15

Figure out why your Vercel build or deploy failed without scrolling the whole log. Reads the build log plus your package manifest and framework config to pinpoint missing modules, Node and package-manager mismatches, missing env vars, monorepo root mistakes, and serverless/edge runtime errors, with the likely cause and a fix for each.

🧭 Doc Drift Detector

by JustHandled Labs

$13

Catch documentation that drifted from your code. Flags functions and methods named in your docs that are gone from the source, CLI flags documented but missing from the arg parser, env vars the docs mention but the code never reads, example imports of modules that no longer exist, and npm scripts or Make targets your docs reference but the project does not define. Cross-references your README and docs against Python and JS/TS source.

nex glb character system

by Nex AI

$7

Hybrid GLB/Procedural character system for Three.js with Draco compression, asset caching, and a selection UI.

playwright pro

by Matthew King

$5

Architect, scaffold, and audit enterprise-grade Playwright test suites with professional CI and auth patterns.

🛡️ MCP Server Starter & Safety Kit

by JustHandled Labs

$29

Scaffold and audit secure MCP servers with input schemas, confirmation gates, and safety-first tool definitions.

Developer Documentation Writer

by Arnstein Larsen

$8.99

Developers don't read documentation — they arrive with a task, scan for the answer, and leave. Docs that aren't structured for that pattern don't get read, they get abandoned
