CLAUDE.md

kakaocli CLAUDE.md is an instructions file for Claude Code from silver-flight-group/kakaocli. It costs 1,474 tokens per session, scanned A, original, MIT.

Project instructions for building and testing a Swift command-line application that decrypts KakaoTalk data and automates its macOS interface. They document its files, SQLCipher database details, and accessibility controls.

In plain words
What is it for?
Building and testing the project, working with its encrypted database, and maintaining KakaoTalk login and self-chat automation.
Why use it?
They record project-specific facts that are easy to get wrong, such as database paths, encryption settings, and how to identify interface elements.

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

kakaocli 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 9d 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.

Build & Test

swift build
swift test

No external dependencies besides sqlcipher (Homebrew). The CSQLCipher system library target wraps it via pkg-config.

Project Structure

  • Sources/KakaoCore/ - Core library: database decryption, models, UI automation
  • Sources/KakaoCLI/ - CLI using swift-argument-parser
  • Sources/CSQLCipher/ - System library modulemap for sqlcipher
  • Tests/KakaoCoreTests/ - Unit tests

Key Technical Details

Database

  • SQLCipher: PRAGMA cipher_default_compatibility = 3 (NOT cipher_compatibility)
  • Container path: com.kakao.KakaoTalkMac (NOT KakaoTalk)
  • DB files: No .db extension - raw hex filenames
  • User ID: Extracted from FSChatWindowTransparency plist key common suffix
  • sqlcipher header: #include <sqlite3.h> (NOT <sqlcipher/sqlite3.h>)

UI Automation (AX)

  • Self-chat: Identified in UI by "badge me" AX image descriptor, NOT by name
  • Main window: id="Main Window" for both login screen AND logged-in state
  • Login screen vs logged-in: Distinguish by window title ("Log in" vs "KakaoTalk") or Logo image
  • Login fields: Two regular AXTextField elements — email first, password second. Password is NOT AXSecureTextField.
  • Non-standard AX hierarchy: kAXWindowsAttribute returns AXApplication elements instead of AXWindow when the window is hidden
  • Status bar menu: Most reliable way to check login state — "Log out" = logged in
  • Window may not appear: After clicking "Open KakaoTalk" in status bar, the AXWindow may take several seconds to materialize or may not appear at all
  • Opening chats: Use AX row selection (kAXSelectedRowsAttribute) + Enter key, NOT doubleClickElement. CGEvent double-click fails when the row is scrolled off-screen (AX reports coordinates outside the visible area). AX selection works regardless of scroll position.
  • Paywall popup: 500x500 blank window at (0,482), invisible to AX, visible to CGWindow API. Dismiss with Escape — but be careful, Escape can also close the main window.

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.
