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

acryl-restyle-ui 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 6d 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 actually says

Restyle or rebrand the Web or Desktop UI

Read {{pack}}/docs/extending/ui-customization.md first (what each surface allows and what is live), then {{pack}}/docs/extending/ui-theme.md and {{pack}}/docs/extending/ui-branding.md, and the token names in {{pack}}/docs/maps/theme-tokens.md. Components you add should use the shared library ({{pack}}/docs/extending/ui-components.md). Copy {{pack}}/example-plugins/packages/client-theme-override/ (and web-page-branding for the favicon and page CSS) into /.acryl-extensions//. Override tokens with BOTH light and dark values; keep contrast readable; never edit node_modules or the app. The tab title is rewritten by the app at runtime: use the observer from the example. Verify, install with acryl_install_plugin, and ask the user to look (it mounts live, no reload) and check light and dark. You cannot see the screen: say what you changed and what you could not verify. Say plainly that upstream text (for example the testing notice) and, on Desktop, the app icon and window chrome cannot be changed by a plugin.

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.
