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

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.

How it starts

The opening of the file, as written. The whole thing — 390 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Theme Personalization

SLICC supports full UI theming via the theme shell command and the Theme settings dialog (avatar menu → "Theme settings…"). In that dialog, select two themes and SLICC applies the darker one in Dark and the brighter one in Light. One selected theme stays on all the time. A third pick replaces the older of the two.

Shell Command (preferred for agent use)

theme list                    # List all preset themes
theme apply <id>              # Apply a preset by id
theme apply <path>            # Apply a .slicc-theme.json file from the VFS
theme reset                   # Reset to default theme
theme export <id> <path>      # Export a preset to a VFS path

Unrecognized flags (for example theme list --json) exit non-zero with theme <sub>: unknown flag: … — do not treat exit 0 as proof a flag was honoured.

Agent workflow

  1. Write a theme JSON file to the VFS
  2. Apply it with theme apply <path>

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.
