codebase-migrate

codebase-migrate is a skill for Claude Code, Codex from composio-community/awesome-codex-skills. It costs 47 tokens per session (1,372 once invoked), scanned C, original, no licence file.

A tool for changing or reorganising many files in a large codebase. A codebase migration is a broad update across existing software, while a multi-file refactor changes code structure without necessarily changing its behaviour.

In plain words
What is it for?
Running large migrations and refactors across hundreds of files, with batched pull requests and CI verification.
Why use it?
It coordinates issue tracking, groups work into batches of pull requests, and checks continuous integration (automated build and test checks) while local transformations run.

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 C, and why

codebase-migrate scanned grade C with 2 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 4d 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.

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.
