lightnovel-immersive-reader AGENTS.md

lightnovel-immersive-reader AGENTS.md is an instructions file for Codex, OpenCode from Catkamakura/lightnovel-immersive-reader. It costs 3,376 tokens per session, scanned A, original, MIT.

Repository instructions for an AI coding agent working on a reading tool for LightNovel.fun. The project includes a browser userscript that adds an immersive reader and an optional service that sends exported books to Calibre.

In plain words
What is it for?
Navigating the project, working on the userscript or Calibre bridge, understanding the site integration, and following the project's development and testing procedures.
Why use it?
They explain how the two project parts fit together and how to build, run, and test them. This helps an agent change the reader without overlooking the browser or book-library side.

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

lightnovel-immersive-reader AGENTS.md 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.

AGENTS.md

Orientation for an AI coding agent (and for Claude Code / Cursor). Start here.

lightnovel-immersive-reader is a two-part personal-reading tool for www.lightnovel.fun. Part 1 is a single-file Tampermonkey userscript (lightnovel-immersive-reader.user.js, ~1900 lines of vanilla JS in one IIFE) that injects a clean, Google-Docs-style immersive reader into the live site without replacing it — it renders into a Shadow-DOM overlay under host lkir-host and reads the site's own JSON web API same-origin (POST /proxy/api/...). It supports continuous-scroll single articles and seamless continuous-scroll web novels (a windowed chapter flow with background prefetch and lazy content-visibility chunk rendering; a settings toggle falls back to the paged one-chapter-per-page reader), auto/manual chapterization, per-chapter bookmarks, a minimap, themes, account-scoped resume, and one-click EPUB/TXT export or send-to-Calibre. Part 2 is calibre-bridge/, an optional FastAPI companion the reader POSTs an EPUB to; it enriches the EPUB's OPF metadata and drops the file into a Calibre-Web-Automated (CWA) ingest folder (import-only — no progress/bookmark sync, no kosync).

Project map

Path What it is
lightnovel-immersive-reader.user.js The whole reader. One IIFE: config/themes → API envelope → helpers (stripTags/esc/norm) → chapterize/buildEpub → render (stream / paged series / seamless flow renderFlow, outline, minimap) → metadata (extractCredits/extractMetaLLM/buildLibMeta) → resume/progress → boot (lkir-host shadow root, SPA route watcher).
package.json npm metadata + verify* scripts. The userscript header @version (currently 2.0.0) is the source of truth for the reader's version.
verify/verify-userscript.mjs Playwright smoke test: injects the script (with a GM_xmlhttpRequest shim) into the live site, opens the reader, asserts UI.
verify/verify-webnovel.mjs Playwright checks for the web-novel (series) mode: seamless flow (append/prepend/leap/bookmarks/minimap) + the paged fallback toggle.
verify/verify-lib.mjs Playwright checks for the send-to-library flow.
calibre-bridge/ Optional FastAPI companion (uv + Docker).
calibre-bridge/bridge/main.py FastAPI app + endpoints (/api/health, /api/import, /api/lookup, /api/books), custom CORS/PNA middleware, bearer-token auth.
calibre-bridge/bridge/epub_meta.py enrich_epub / enrich_opf_bytes: rewrites the EPUB's OPF (Dublin-Core + Calibre fields, MARC relator roles).
calibre-bridge/bridge/calibre.py import_epub: drop into CWA ingest folder (default) or add via calibredb CLI.
calibre-bridge/bridge/store.py SQLite book registry (upsert_book/list_book/get_book) for /api/lookup.
calibre-bridge/bridge/config.py Env-driven Config (BRIDGE_MODE, INGEST_DIR, STATE_DB, CORS_ORIGINS, BRIDGE_TOKEN).
calibre-bridge/tests/ pytest suite (OPF enrichment, store, API import/auth).
calibre-bridge/{Dockerfile,docker-compose.yml,.env.example} Container scaffold that stands up CWA and the bridge together.
calibre-bridge/README.md The bridge's user/operator doc (architecture, deploy modes, caveats).
docs/ The English wiki: architecture, userscript reference, metadata, lk-web-api, calibre-bridge, development.

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.
