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
