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 | $0.00116 | $0.02640 |
| Opus 5.5 | $0.00046 | $0.01056 |
| Sonnet 5.5 | $0.00023 | $0.00528 |
| Haiku 4.5 | $0.00012 | $0.00264 |
Grade A, and why
bloom-branding 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 — 84 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Bloom Branding Packs
Outcome
Confidently edit a branding pack and know exactly what makes the change show up in a real book, without guessing. Branding is data + CSS + assets that Bloom stamps onto a book's front/back matter at "bring up to date" time.
Branding folder anatomy
Each pack is src/content/branding/<Name>/:
branding.json— the data. Apresetsarray; each entry sets adata-bookvalue on the book's bloomDataDiv. Fields:data-book,lang(usually"*"),content(literal HTML/text),condition(always= always overwrite,ifEmpty= only fill if blank). A"//"key is a comment (ignored).branding.less— pack-specific formatting. Must@import "../branding-base.less";. Compiles tobranding.css.- image assets —
.png/.svg/.jpgreferenced bybranding.json(logos, the made-with-bloom badge). These must physically live in the pack folder. summary.htm— the text/logo Bloom shows in the subscription settings summary (BrandingSettings.csreads it and replaces{flavor}andSUBUNIT).
Division of labor (stated at top of branding-base.less): rules that place branding on an xmatter page go in bloom-xmatter-common.less / the xmatter's .less; rules that format branding go in branding-base.less or the pack's branding.less.
Common data-book branding slots
Set via branding.json presets; rendered by mixins in src/content/templates/xMatter/bloom-xmatter-mixins.pug:
xmatter— selects the xmatter pack the branding uses (e.g."MXBScripture"→ MXBScripture-XMatter). This is how a branding picks its front/back matter.outside-back-cover-branding-bottom-html— the back-cover badge (the "Made with Bloom" / QR badge).title-page-branding-bottom-html— logo at the bottom of the title page.cover-branding-top-html,cover-branding-bottom-html,credits-page-branding-bottom-html,inside-back-cover-branding-top-html, etc.- non-branding presets too:

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.

bloom-branding is a skill published in the GitHub repository BloomBooks/BloomDesktop (43 stars, last pushed today), licensed MIT. It adds 116 tokens to every session and 2,640 once invoked, about $0.0005 per session on Opus 5.5. 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.
