What is book CLAUDE.md?

Project instructions for maintaining and developing an open-source Flutter novel-reader application written in Dart.

Use them when installing dependencies, analyzing code, running the app or tests, building Android packages, or regenerating project files.

They give an agent the project's package details, dependencies, commands, SDK requirements, and checks needed to work consistently in the repository.

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.

Model	Per session	Once invoked
Fable 5.1	$0.03032	$0.03032
Opus 5.5	$0.01213	$0.01213
Sonnet 5.5	$0.00606	$0.00606
Haiku 4.5	$0.00303	$0.00303

Security

Grade A, and why

book CLAUDE.md 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 2mo 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.

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

Project

爱看书 — open-source Flutter novel reader. Package name: book. Application ID: com.opensource.ikanshu. License: Apache-2.0.

Tech stack: Dart 3 / Flutter 3.44+, Riverpod (flutter_riverpod + ChangeNotifierProvider), event_bus, Dio 5, Fluro, sqflite, protobuf, shared_preferences (via local SpUtil facade).

SDK constraint: sdk: ^3.12.0 — sound null safety. Target Flutter 3.44 stable (Dart 3.12).

Commands

# Install dependencies
flutter pub get

# Analyze (flutter_lints via analysis_options.yaml)
flutter analyze

# Run on a connected device/emulator
flutter run

# Run tests
flutter test
flutter test test/widget_test.dart   # single test file

# Debug APK (requires a valid Android SDK / ANDROID_HOME)
flutter build apk --debug

# Release APK (CI-style)
flutter build apk

# Release APK matching build.bat (obfuscated, arm64 split, SKSL warm-up)
flutter build apk --obfuscate --split-debug-info=HLQ_Struggle --target-platform android-arm64 --split-per-abi --build-name=4.2.3 --build-number=3 --bundle-sksl-path flutter_01.sksl.json

# Regenerate json_serializable code (optional; *.g.dart are also hand-maintained)
dart run build_runner build --delete-conflicting-outputs

build.bat / build_arm64.bat are the project’s release build scripts (Windows).

GitHub Actions:

.github/workflows/ci.yml — flutter analyze + flutter test on push/PR
.github/workflows/build.yml — release APK on master/main, tags v*, workflow_dispatch, and repository_dispatch type starred; optional signing via ANDROID_KEYSTORE_* secrets; uploads artifacts and creates a GitHub Release for tags

There is no separate lint script beyond flutter analyze. file_names is enabled (all lib paths are snake_case). Residual SpUtil/API-shaped identifiers still suppress non_constant_identifier_names / constant_identifier_names.

pubspec.yaml uses dependency_overrides.platform: ^3.1.6 because transitive sqflite_platform_interface otherwise pulls platform 3.0.0, which references removed io.Platform.packageRoot on Dart 3.12.

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.
