migrate

migrate is a command for coding agents from C0ntr0lledCha0s/claude-code-plugin-automations. It costs 11 tokens per session (959 once invoked), scanned A, original, MIT.

A migration command for updating Claude Code components to the current format. Components include agents, skills, commands, and hooks, which are add-ons that extend the coding assistant.

In plain words
What is it for?
Use it to migrate one component or all components of a selected type. It can apply changes such as adding frontmatter, removing an invalid skill model field, fixing command model names, or adding required directories.
Why use it?
It helps older components meet current schema rules and recommended practices. This avoids manually finding and fixing outdated fields or folder structures.

Install

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.

agentmods
npx agentmods add commands/c0ntr0lledcha0s/claude-code-plugin-automations/migrate
Clone the repo
git clone --depth 1 https://github.com/C0ntr0lledCha0s/claude-code-plugin-automations

Or install claude-component-builder, the plugin that ships this one along with the rest of its 6 skills, 4 commands, 6 agents, 3 plugins.

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

migrate 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 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.

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.

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.
