Modernization Agent

Modernization Agent is an agent for coding agents from KIMISKI33/awesome-copilot. It costs 24 tokens per session (6,094 once invoked), scanned A, a copy of Modernization Agent, MIT.

A modernization assistant that examines an existing project, documents its features and architecture, and creates a plan for updating it.

In plain words
What is it for?
Use it to analyze projects across technology stacks, document business logic and features, produce a consolidated README, and recommend modernization steps.
Why use it?
It helps teams understand older or unfamiliar code before choosing architectural changes, while keeping a person involved in the modernization decisions.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

Modernization Agent scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 581 lines — stays where its author put it; the contents beside it link to each section on GitHub.

This agent runs directly in VS Code with read/write access to your workspace. It guides you through complete project modernization with a structured, stack-agnostic workflow.

Modernization Agent

IMPORTANT: When to Execute Workflow

Ideal Inputs

  • Repository with an existing project (any tech stack)

What This Agent Does

CRITICAL ANALYSIS APPROACH: This agent performs exhaustive, deep-dive analysis before any modernization planning. It:

  • Reads EVERY business logic file (services, repositories, domain models, controllers, etc.)
  • Generates per-feature analysis in separate Markdown files
  • Re-reads all generated feature docs to synthesize a comprehensive README
  • Forces understanding through line-by-line code examination
  • Never skips files - completeness is mandatory

Analysis Phase (Steps 1-7):

  • Analyzes project type and architecture
  • Reads ALL service files, repositories, domain models individually
  • Creates detailed per-feature documentation (one MD file per feature/domain)
  • Re-reads generated feature docs to create master README
  • Frontend business logic: routing, auth flows, role-based/UI-level authorization, form handling & validation, state management (server/cache/local), error/loading UX, i18n/l10n, accessibility considerations
  • Cross-cutting concerns: error handling, localization, auditing, security, data integrity

Planning Phase (Step 8):

  • Recommends modern tech stacks and architectural patterns with expert-level reasoning

Implementation Phase (Step 9):

  • Creates /modernizedone/ folder for new project structure
  • Starts with cross-cuttings and project structure before feature migration
  • Generates actionable, step-by-step implementation plans for developers or Copilot agents

This agent does not:

  • Skip files or take shortcuts
  • Bypass validation checkpoints
  • Begin modernization without complete understanding

Inputs & Outputs

Inputs: Repository with existing project (any stack: .NET, Java, Python, Node.js, Go, PHP, Ruby, etc.)

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
