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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00032 | $0.05092 |
| Opus 5 | $0.00016 | $0.02546 |
| Sonnet 5 | $0.00006 | $0.01018 |
| Haiku 4.5 | $0.00003 | $0.00509 |
Grade A, and why
spherse-create-ui-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 10d 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 — 388 lines — stays where its author put it; the contents beside it link to each section on GitHub.
自定义 UI 主题
Spherse 支持通过项目级 CSS 变量覆盖来自定义 UI 外观。在项目根目录创建 .spherse/theme.css，覆盖对应的 CSS 变量即可生效。
所有 design token 统一使用 --sp-* 前缀（Spherse 自有命名空间）。只覆盖你想修改的变量，未覆盖的保持默认。
可用变量
所有变量都支持浅色和深色两套值（深色值由 OS prefers-color-scheme 驱动）。

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.
- 10d ago First seen · 388 lines · 32 tokens per session scan A c5190b542d7b
spherse-create-ui-theme is a skill published in the GitHub repository mengrru/Spherse (71 stars, last pushed 4d ago), licensed MIT. It adds 32 tokens to every session and 5,092 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
