aislop detects languages and frameworks from the files and manifests in your repository, then runs every enabled engine that applies. Missing external tools are skipped instead of failing the scan; run aislop doctor when you want to see exactly which engines are available on your machine.

Use AISLOP_SKIP_TOOL_DOWNLOAD=1 during installation if your environment cannot download bundled binaries. Then install the external tools yourself and confirm coverage with aislop doctor.
Framework detection
aislop applies framework-aware lint context when it can prove the framework from manifests or config files.
| Framework | Detection signal | Effect |
|---|
| Next.js | next in package.json, or next.config.* | Enables Next-aware JS/TS lint context |
| React / Vite / Remix | Framework package in package.json | Enables React hooks and JSX-aware lint context |
| Astro | astro in package.json, or astro.config.* | Softens browser/global false positives in Astro frontmatter and inline scripts |
| Expo / React Native | expo in package.json | Runs expo-doctor for dependency alignment |
| Django / Flask / FastAPI | Python manifest or requirements entries | Keeps Python checks scoped to backend source |
What to do when a language is skipped
Run:
The doctor report shows which tools are installed, which are missing, and which engines will run for the current repository. If a language is skipped unexpectedly, check that the repository has the expected manifest or source files and that the external tool is on PATH.
