What is claude-code-chat-intellij CLAUDE.md?

Development instructions for an IntelliJ IDEA plugin that connects the Claude Code command-line tool to the IDE. They describe its architecture, commands, testing, and build process.

Working on the plugin's Swing interface, command-line connection, slash commands, file references, settings, saved sessions, and event hooks. They also help run its build and tests.

They give an coding agent the repository context needed to work consistently on the plugin. This reduces guesswork about where features belong and how to build or test changes.

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	$0.00960	$0.00960
Opus 5	$0.00480	$0.00480
Sonnet 5	$0.00192	$0.00192
Haiku 4.5	$0.00096	$0.00096

Security

Grade A, and why

claude-code-chat-intellij 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.

🏗️ Architecture Overview

This is an IntelliJ IDEA plugin that integrates Claude Code CLI with the IDE. The architecture follows IntelliJ Platform conventions with:

Swing-based UI (src/main/kotlin/com/claudecodechat/ui/swing/) - Stable Swing UI components for maximum compatibility
CLI Integration (src/main/kotlin/com/claudecodechat/cli/) - Handles Claude CLI process execution and communication
Completion System (src/main/kotlin/com/claudecodechat/completion/) - Slash commands (/) and file references (@)
State Management (src/main/kotlin/com/claudecodechat/state/) - Session and conversation state handling
Settings (src/main/kotlin/com/claudecodechat/settings/) - Plugin configuration and environment variables
Persistence (src/main/kotlin/com/claudecodechat/persistence/) - Session storage and management
Hook System (src/main/kotlin/com/claudecodechat/hooks/) - Event handling and integration points

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.
