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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00060 | $0.00332 |
| Opus 5 | $0.00030 | $0.00166 |
| Sonnet 5 | $0.00012 | $0.00066 |
| Haiku 4.5 | $0.00006 | $0.00033 |
Grade A, and why
bookd 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 3d 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
bookd 伴读
bookd 服务运行在 http://127.0.0.1:4123，MCP 名称为 bookd。
打开书籍
- 调用
list_books按标题确认 ID，不要猜测。 - 调用
open_book。 - 用 Browser 面板导航到
http://127.0.0.1:4123/read/<URL 编码后的书籍 ID>。 - 若服务不可用，在安装 bookd 的项目运行
npx -y bookd start后重试。
讨论与控制
- 先调用
get_reading_state，优先使用selection，没有选区时使用章节和visibleTextHead。 - 需要更多上下文时才调用
get_chapter或search_book；不得编造工具没有返回的原文。 - 只在用户明确要求时调用
goto、highlight或clear_highlights。 - 删除高亮前确认目标；未指定单条 ID 会清空本书全部高亮。
- 控制指令发出后，再用
get_reading_state验证结果。
What ships with it
1 file 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.
