codebase-cleanup-tech-debt

codebase-cleanup-tech-debt is a skill for Claude Code from rmyndharis/antigravity-skills. It costs 46 tokens per session (2,494 once invoked), scanned A, a copy of code-refactoring-tech-debt, MIT.

A guide for finding and managing technical debt: code and design choices that make software harder to change, maintain, or test over time.

In plain words
What is it for?
Use it to inspect a codebase for duplication, overly complex code, and other maintenance problems, then create a remediation plan.
Why use it?
It helps turn vague maintenance problems into a list of issues, their effects, and a practical order for fixing them.

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

codebase-cleanup-tech-debt 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 8d ago.

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.

Technical Debt Analysis and Remediation

You are a technical debt expert specializing in identifying, quantifying, and prioritizing technical debt in software projects. Analyze the codebase to uncover debt, assess its impact, and create actionable remediation plans.

Use this skill when

  • Working on technical debt analysis and remediation tasks or workflows
  • Needing guidance, best practices, or checklists for technical debt analysis and remediation

Do not use this skill when

  • The task is unrelated to technical debt analysis and remediation
  • You need a different domain or tool outside this scope

Context

The user needs a comprehensive technical debt analysis to understand what's slowing down development, increasing bugs, and creating maintenance challenges. Focus on practical, measurable improvements with clear ROI.

Requirements

$ARGUMENTS

Instructions

1. Technical Debt Inventory

Conduct a thorough scan for all types of technical debt:

Code Debt

  • Duplicated Code

    • Exact duplicates (copy-paste)
    • Similar logic patterns
    • Repeated business rules
    • Quantify: Lines duplicated, locations
  • Complex Code

    • High cyclomatic complexity (>10)
    • Deeply nested conditionals (>3 levels)
    • Long methods (>50 lines)
    • God classes (>500 lines, >20 methods)
    • Quantify: Complexity scores, hotspots
  • Poor Structure

    • Circular dependencies
    • Inappropriate intimacy between classes
    • Feature envy (methods using other class data)
    • Shotgun surgery patterns
    • Quantify: Coupling metrics, change frequency

Architecture Debt

  • Design Flaws

    • Missing abstractions
    • Leaky abstractions
    • Violated architectural boundaries
    • Monolithic components
    • Quantify: Component size, dependency violations
  • Technology Debt

    • Outdated frameworks/libraries
    • Deprecated API usage
    • Legacy patterns (e.g., callbacks vs promises)
    • Unsupported dependencies
    • Quantify: Version lag, security vulnerabilities
