What is it for?
Use them to compile, package, install, debug, or understand the extension’s chat data flow.
Why use it?
They help an agent work within the project’s Windows and Git Bash requirements and avoid known packaging mistakes.

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

Claude-code-ChatInWindows 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 4d 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.

How it starts

The opening of the file, as written. The whole thing — 211 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Development Environment

  • OS: Windows 10.0.19045
  • Shell: Git Bash
  • Path format: Windows (use forward slashes in Git Bash)
  • File system: Case-insensitive
  • Line endings: CRLF (configure Git autocrlf)

Build & Package

Compile:

npm run compile

Package VSIX (must use cmd wrapper, Git Bash swallows vsce output):

cmd //c "npx @vscode/vsce package --no-dependencies"
  • --no-dependencies: skips npm install during packaging — dependencies are already in node_modules from development; without this flag, vsce may fail or produce a bloated package
  • Do NOT use npx @vscode/vsce package directly in Git Bash — it silently fails (exit 0 but no .vsix generated)
  • Output file: claude-code-chatui-{version}.vsix

Install VSIX for testing:

  • VS Code: Ctrl+Shift+P → "Install from VSIX"
  • CLI: code --install-extension claude-code-chatui-{version}.vsix

Debug (Extension Development Host):

  • Ctrl+Shift+D → select "Run Extension" → click green play button
  • Remote desktop: F5 may be intercepted, use the play button instead

Architecture Overview

Data Flow

User input → Webview postMessage → ClaudeChatProvider
  → ClaudeProcessService (stdin JSON) → Claude CLI
  → stdout JSON stream → MessageProcessor → postMessage → Webview

Key Components

Component File Role
Entry point src/extension.ts Registers commands, subscriptions, status bar
Webview orchestrator src/providers/ClaudeChatProvider.ts Owns all managers/services, handles all webview messages
CLI lifecycle src/services/ClaudeProcessService.ts Spawn, kill, temp-file cleanup
Stream parser src/services/MessageProcessor.ts JSON-line parsing, tool-use extraction, token/cost dispatch
Process mgmt src/managers/WindowsCompatibility.ts Executable discovery, taskkill tree kill, shell env
Config facade src/managers/config/ConfigurationManagerFacade.ts Combines VsCode + MCP + API config managers
Undo/redo src/managers/UndoRedoManager.ts Strategy pattern — one strategy class per operation type
UI HTML src/ui-v2/index.ts Assembles full HTML: CSP header + styles + body + script
UI script src/ui-v2/ui-script.ts Entire frontend JS as a TypeScript template literal
UI body src/ui-v2/getBodyContent.ts HTML body markup (settings panel, chat area, footer)

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.
