What is kmsg AGENTS.md?

Repository instructions for building and manually testing kmsg, a Swift command-line tool that controls KakaoTalk on macOS through its accessibility interface. They also describe how commands connect to the app and its user-interface tree.

Use them when developing or manually checking commands that inspect chats, read messages, or send messages in KakaoTalk. They also help maintain the Swift wrappers around macOS accessibility features.

They explain how to build the tool and check its status, visible interface, chats, messages, and sending behavior without accidentally sending a message. They provide the project structure needed to make changes in the right layer.

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	$0.00579	$0.00579
Opus 5.5	$0.00232	$0.00232
Sonnet 5.5	$0.00116	$0.00116
Haiku 4.5	$0.00058	$0.00058

Security

Grade A, and why

kmsg AGENTS.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.

Build Commands

swift build                    # Debug build
swift build -c release         # Release build
.build/debug/kmsg [command]    # Run debug build
.build/release/kmsg [command]  # Run release build

Testing

No automated test suite. Test manually:

.build/debug/kmsg status --verbose           # Check accessibility & app status
.build/debug/kmsg inspect --depth 5          # Inspect UI hierarchy
.build/debug/kmsg chats --verbose --limit 20 # List chats
.build/debug/kmsg send "Name" "msg" --dry-run # Test send without sending
.build/debug/kmsg read "Chat" --limit 50     # Read messages

Architecture

CLI Commands (Commands/*.swift)
        ↓
  KakaoTalkApp (High-level business logic)
        ↓
    UIElement (Accessibility API wrapper)
        ↓
macOS Accessibility APIs (AXUIElement)

Key components:

UIElement (Accessibility/UIElement.swift): Wrapper around AXUIElement with breadth-first search, attribute access, hierarchy traversal. Supports limit parameter for early termination.
KakaoTalkApp (KakaoTalk/KakaoTalkApp.swift): Process lifecycle, window management, auto-launch with timeout. Thread-safe via Sendable.
Commands: Each implements ParsableCommand. Handle CLI interaction, permission checks, delegate business logic to KakaoTalkApp.

KakaoTalk UI Structure

Main Window (id: Main Window):
├── Navigation: id: friends, id: chatrooms, id: more
├── Unread count: AXStaticText
└── Content: AXScrollArea > AXTable > AXRow > AXCell

Chat Window (title = chat name):
├── Messages: AXScrollArea > AXTable > AXRow
└── Input: AXTextArea or AXTextField

Technical Notes

Bundle ID: com.kakao.KakaoTalkMac
Requires Accessibility permission (System Settings > Privacy & Security > Accessibility)
Keyboard input uses CGEvent for Korean text (Unicode support)
Search methods support limit for early termination - use to avoid full UI traversal
All classes interacting with accessibility APIs should be Sendable
For version bumps, release tags, or release automation changes, follow VERSIONING.md

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.
