Modernize legacy codebases (COBOL, legacy Java/C++/.NET, monolith web apps) with a structured preflight / assess / map / extract-rules / brief / (reimagine | transform | uplift) / harden / status workflow. Cross-stack rewrites, greenfield reimagining, and same-stack version uplifts (e.g. .NET Framework → .NET 8); an interactive topology viewer; specialist agents; and optional dynamic-workflow orchestration with adversarial verification.
Uses power tools
Uses Bash, Write, or Edit tools
Based on adoption, maintenance, documentation, and repository signals. Not a security audit or endorsement.
Full discovery & portfolio analysis of a legacy system — inventory, complexity, debt, relative scale
Generate a phased Modernization Brief — the approved plan that transformation agents will execute against
Mine business logic from legacy code into testable, human-readable rule specifications
Security vulnerability scan with a reviewable remediation patch — OWASP, CWE, CVE, secrets, injection
Dependency & topology mapping — call graphs, data lineage, batch flows, rendered as navigable diagrams
Reviews proposed target architectures and transformed code against modern best practice. Adversarial — looks for over-engineering, missed requirements, and simpler alternatives.
Mines domain logic, calculations, validations, and policies from legacy code into testable Given/When/Then specifications. Use when you need to separate "what the business requires" from "how the old code happened to implement it."
Deep-reads legacy codebases (COBOL, Java, .NET, Node, anything) to build structural and behavioral understanding. Use for discovery, dependency mapping, dead-code detection, and "what does this system actually do" questions.
Scaffolds one service of a reimagined system from the approved architecture and spec — project skeleton, domain model, API stubs, executable acceptance tests. Write access is scoped to its own service directory under modernized/.
Adversarial security reviewer — OWASP Top 10, CWE, dependency CVEs, secrets, injection. Use for security debt scanning and pre-modernization hardening.
A curated, installable marketplace of Agent Skills and plugins for Claude Code, assembled from the best available skills across the web plus a few authored to fill gaps. It covers coding & review, tool/agent development, frontend & UI/UX design, web & landing pages, animation, automation, planning, document handling, token efficiency, and India-focused business domains (retail, warehousing, agri-business, CA practice).
Most skills are the official Anthropic skills/plugins, imported verbatim with their licenses; a few popular third-party skills (MIT) are included with attribution; and the niche/business + token-efficiency skills are authored here.
This repo is a Claude Code plugin marketplace.
