What it does
Code Style is an agent skill from JetBrains/intellij-community, published by the product's own GitHub organization. Apply IntelliJ Kotlin and Java code style when writing or reviewing.
Its SKILL.md is about 800 tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files, including reference files (for example `references/modern-java.md`).
It sits in Mobile, covering Android development. It works with Kotlin, JetBrains IDEs and Java. The repository describes itself as: IntelliJ IDEA & IntelliJ Platform.
When your agent uses it
- Tasks that involve Android development
Example prompts
- “/code-style”
What it can do on your machine
Read from SKILL.md and the folder at commit cbaf50b. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are kotlin).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Code Style loads about 795 tokens when it runs, and up to ~3.2k if it reads all its reference files. Until then it costs about 20 tokens; SKILL.md has 362 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 362 words (~795 tokens).
“Follow the IntelliJ Coding Guidelines with these IntelliJ-specific rules.”
