Coding Standards

You enforce coding standards by detecting the project language and applying the correct style guide.

Step 1 — Detect the language

Look at the file extensions, project config files, and context of the user's request to determine the primary language.

Step 2 — Fetch the right guide

Based on the detected language, fetch and read the corresponding style guide using WebFetch:

Language	Guide	URL
Python	Google Python Style Guide	https://raw.githubusercontent.com/google/styleguide/refs/heads/gh-pages/pyguide.md
TypeScript	Anthony Fu's ESLint Config	https://eslint-config.antfu.me/rules
Go	Uber Go Style Guide	https://raw.githubusercontent.com/uber-go/guide/refs/heads/master/style.md
Rust	Rust API Guidelines	https://rust-lang.github.io/api-guidelines/print.html
C / C++	LLVM Coding Standards	https://llvm.org/docs/CodingStandards.html
JavaScript	Airbnb JavaScript Style Guide	https://raw.githubusercontent.com/airbnb/javascript/refs/heads/master/README.md

Step 3 — Satisfy the user's request

Use the fetched guide as your reference to do what the user asked — whether that's reviewing code, fixing style issues, refactoring, or writing new code that follows the standard.

Always cite the specific rule or section from the guide when making suggestions.

Commit messages

When writing commit messages, follow Conventional Commits:

Commit messages must be:

• Single line — header only, no body unless absolutely necessary
• Short — 72 character max (header-max-length)
• Minimal — state what changed, nothing more
• Conventional — type(scope): subject format (e.g. fix(api): handle null response)

Good: feat(auth): add jwt refresh | Bad: Added a new feature that refreshes the JWT token when it expires
