kotlin-style

kotlin-style is a cursor rule for Cursor from lockelee1015/claude-code-chat-intellij. It costs 0 tokens per session (274 once invoked), scanned A, original, MIT.

A set of Kotlin coding rules for readability, type safety, error handling, formatting, comments, and coroutine use. Detekt is an automated Kotlin code-quality checker, and these rules describe how to handle its findings.

In plain words
What is it for?
Use it when naming code, designing public APIs, handling errors and boundaries, writing concurrent code with coroutines, formatting files, and deciding when a Detekt exception is justified.
Why use it?
It gives contributors a shared style for Kotlin code and limits inconsistent patterns, unclear errors, unsafe casts, and unnecessary 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.

Security

Grade A, and why

kotlin-style 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.

What it actually says

Kotlin 风格与实践

  • 命名:使用有意义的全词,避免 1-2 字母名;函数用动词短语,变量用名词短语。
  • 类型:对公开 API 显式标注类型;避免使用 Any 与不安全强转。
  • 控制流:优先使用卫语句;先处理错误与边界;避免深层嵌套。
  • 错误处理:不要无意义地 catch;日志需包含上下文;返回值为空时清晰表达。
  • 格式化:遵循项目现有格式;多行比过长单行更可读;避免无关改动。
  • 注释:仅在复杂语义前添加,解释“为什么”;避免冗余与行内注释。
  • 并发:优先使用协程;为 suspend 函数提供清晰的取消与超时策略。

Detekt

  • 遵循 detekt.yml 规则;如需例外,应在最小作用域内抑制并说明原因。

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.
