auto-theme

auto-theme is a plugin for Claude Code from IvanLutsenko/awac-ai-agent-plugins. Its manifest loads nothing; the 1 skill it bundles cost 61 tokens per session together, scanned A, original, MIT.

A macOS add-on that changes Claude Code and Codex editor themes to match the computer’s light or dark system appearance. It includes the gruvbox-light and sunset-drive themes and installs them on first use.

In plain words
What is it for?
Use it to synchronize Claude Code and Codex between light and dark themes on macOS, including the bundled custom themes.
Why use it?
The editor theme can otherwise stay different from the rest of the desktop after the system appearance changes. This keeps the two editors aligned with macOS automatically when a prompt is submitted.

Security

Grade A, and why

auto-theme 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 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.

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 it installs

The manifest is a name and a version. 1 skill travel with it, and installing the plugin installs all of them — 61 tokens a session between them. Each is measured on its own page, and each can be installed alone.

Changes

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.
