Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00023 | $0.03303 |
| Opus 5.5 | $0.00009 | $0.01321 |
| Sonnet 5.5 | $0.00005 | $0.00661 |
| Haiku 4.5 | $0.00002 | $0.00330 |
Grade A, and why
code-migrator scanned grade A with 1 finding 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 1mo 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.

Code Migrator
⚡ UNIQUE FEATURE: Automated legacy code modernization with AI-powered migration paths, dependency resolution, test generation, and risk analysis. Migrate between languages, frameworks, or architectural patterns with confidence.
What This Skill Does
Intelligently migrates codebases with minimal manual intervention:
Language Migrations
- Python 2 → Python 3: Syntax, imports, unicode handling
- JavaScript → TypeScript: Type inference and definitions
- Java 8 → Java 17+: Modern language features
- Angular.js → React/Vue: Complete framework migration
- PHP 5 → PHP 8: Modernize deprecated features
- Ruby 2 → Ruby 3: Update syntax and gems
Framework Upgrades
- React Class → Hooks: Convert class components
- Vue 2 → Vue 3: Composition API migration
- Django 2 → Django 4: Settings and ORM updates
- Rails 5 → Rails 7: Modern Rails patterns
- Express 4 → Express 5: Route handlers, middleware
Architectural Migrations
- Monolith → Microservices: Service extraction
- REST → GraphQL: API transformation
- Callback Hell → Async/Await: Promise modernization
- MVC → Component-Based: Architecture refactoring
Why This Is Revolutionary
First migration skill with:
- AI-powered analysis: Understands code context and intent
- Risk assessment: Identifies high-risk changes
- Incremental migration: Migrate module by module
- Automated testing: Generates tests to verify migration
- Rollback support: Safe migration with undo capability
- Dependency resolution: Automatically updates imports and packages
- Pattern recognition: Identifies and modernizes anti-patterns
Instructions
Phase 1: Migration Discovery & Analysis
-
Identify Migration Type:
Ask user: - What are you migrating FROM? - What are you migrating TO? - Full codebase or specific modules? - Any constraints or requirements? -
Analyze Current State:
# Discover project structure Use Glob to find all source files Use Grep to identify: - Framework versions - Import patterns - Deprecated APIs - Code smells
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

code-migrator is a skill published in the GitHub repository glincker/claude-code-marketplace (37 stars, last pushed 19d ago), licensed Apache-2.0. It adds 23 tokens to every session and 3,303 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
