app-tone-manner

app-tone-manner is a plugin for Claude Code from sean-sunagaku/claude-code-plugin. Its manifest loads nothing; the 1 skill, 8 agents it bundles cost 764 tokens per session together, scanned A, original, MIT.

A team-based process for defining an app's visual identity and writing style, including colors, typography, imagery, and tone of voice. It produces Pencil files and Markdown documents.

In plain words
What is it for?
Use it to define brand personality, visual direction, design tensions, interface styling, and the language an app should use.
Why use it?
It gives an app a consistent look and communication style instead of leaving design choices to be made separately in each screen or message.

Security

Grade A, and why

app-tone-manner 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 it installs

The manifest is a name and a version. 1 skill, 8 agents travel with it, and installing the plugin installs all of them — 764 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.
