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 | $0.00069 | $0.04307 |
| Opus 5.5 | $0.00028 | $0.01723 |
| Sonnet 5.5 | $0.00014 | $0.00861 |
| Haiku 4.5 | $0.00007 | $0.00431 |
Grade A, and why
edit-bloom-book 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 — 328 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Edit Bloom book
Outcome
Edit a book's .htm file without breaking Bloom's structural expectations. Preserve the DOM schema Bloom relies on for page identity, multilingual text, images, canvas elements, xMatter regeneration, and split-pane layouts.
When To Use
- The user wants to edit a book's
.htmdirectly. - The user needs help repairing a damaged or hand-edited Bloom book.
- The task involves changing text, image containers, layout wrappers, or metadata while keeping the book valid.
- The task requires adding or repairing Bloom-specific elements such as
.bloom-page,.bloom-translationGroup,.bloom-editable,.bloom-canvas, or split-pane containers.
Validator Script
- Before and after structural edits, run the validator script in this skill folder.
- Command:
node .claude/skills/edit-bloom-book/validateBloomBook.mjs path/to/Book.htm
- It accepts multiple books:
node .claude/skills/edit-bloom-book/validateBloomBook.mjs book1.htm book2.htm
- Current validator scope checks Bloom's core book schema and the common strict layout subtrees:
- HTML parseability in a browser-style DOM
- source-level root placement of
.bloom-pageelements - presence of
#bloomDataDiv - presence of
meta[name="BloomFormatVersion"] - at least one
.bloom-page - every
.bloom-pageat body root level - non-empty unique page ids and expected page shell wrappers
- non-empty
langon every.bloom-editable .bloom-translationGroup/div.bloom-editablechild structure- split-pane component/divider/inner wrapper structure
- modern canvas-element image containers and legacy direct-image
bloom-canvasstructures - unique ids on
p,img, andtextarea
- Treat validator failures as blockers for direct book edits.
Structural Grammar
This is the concise model the validator enforces. * means zero or more, ? means optional, and quoted class names mean the element must include that class, though it may also carry other Bloom classes.
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

edit-bloom-book is a skill published in the GitHub repository BloomBooks/BloomDesktop (43 stars, last pushed today), licensed MIT. It adds 69 tokens to every session and 4,307 once invoked, about $0.0003 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.
