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

aio-epub-translate scanned grade A with 1 finding 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 5d 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.

EPUB Translate — Chapter Translation

Dịch nội dung EPUB bằng khả năng ngôn ngữ của Claude, submit bản dịch qua API.

Prerequisites: Cần API key (aio-epub-setup) và sách đã upload (aio-epub-upload). Chưa có sách? Dùng aio-epub-manage để xem danh sách.

API Setup

LUÔN dùng Python — KHÔNG dùng bash curl (JSON escaping lỗi với Unicode).

import json, urllib.request, os

BASE = "https://read-api.aiocean.dev/ListBooks.v1.BookService"
KEY = os.environ.get("AIO_EPUB_API_KEY", "")

def api(method, body):
    data = json.dumps(body).encode('utf-8')
    req = urllib.request.Request(f"{BASE}/{method}", data=data, headers={
        "Content-Type": "application/json",
        "X-License-Key": KEY
    })
    with urllib.request.urlopen(req) as resp:
        return json.loads(resp.read())

Workflow

1. Parse URL (nếu user gửi link)

URL format: https://read.aiocean.io/books/{bookId}/read/{filePath}

  • filePath có thể double-encoded: Text%252Fchapter0018.htmlText/chapter0018.html

2. Lấy context TRƯỚC KHI DỊCH

# Lấy cross-chapter context (guideline + glossary + previous chapter summary)
context = api("GetChapterContext", {
    "bookId": BOOK_ID,
    "filePath": FILE_PATH
})
guideline = context.get("guideline", "")
chapter_guideline = context.get("chapterGuideline", "")
previous_summary = context.get("previousChapterSummary", "")
glossary = context.get("glossary", [])

print("=== GUIDELINE ===")
print(guideline)
if chapter_guideline:
    print("=== CHAPTER GUIDELINE ===")
    print(chapter_guideline)
if glossary:
    print("=== GLOSSARY (recurring terms) ===")
    for term in glossary:
        print(f"  {term['original']} → {term['translated']} (x{term['frequency']})")
if previous_summary:
    print("=== PREVIOUS CHAPTER (last paragraphs) ===")
    print(previous_summary[:500])

3. Lấy nội dung cần dịch

page = api("GetPageJson", {
    "bookId": BOOK_ID,
    "filePath": FILE_PATH,
    "size": 0,    # 0 = tất cả
    "offset": 0
})
contents = page["contents"]
print(f"Total items: {len(contents)}")

# Filter items chưa dịch hoặc dịch kém
items_to_translate = []
for item in contents:
    translations = item.get("translations", [])
    if not translations or not translations[0].get("contentText", "").strip():
        items_to_translate.append(item)
print(f"Need translation: {len(items_to_translate)}")

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.
