# Check engine availability

> Check which aislop engines, tools, and language targets can run in the current project.

`aislop doctor` inspects the current environment and reports which engines can run. Use it when setting up a new machine, debugging skipped engines, or validating CI images.

## Usage

```bash theme={null}
aislop doctor
aislop doctor ./packages/api
```

## What doctor checks

| Area               | What it reports                                                 |
| ------------------ | --------------------------------------------------------------- |
| Project coverage   | Supported language files found in the target directory          |
| Formatting tools   | Biome, ruff format, gofmt, cargo fmt, rubocop, php-cs-fixer     |
| Linting tools      | oxlint, ruff, golangci-lint, clippy, expo-doctor                |
| Code quality tools | Complexity checks, knip availability, unused dependency checks  |
| Security tools     | Secret checks, risky-code checks, dependency audit availability |
| Architecture rules | Whether custom Architecture engine rules are configured         |

## When to run it

```bash theme={null}
# After installing aislop
aislop doctor

# Before enabling strict CI in a monorepo package
aislop doctor ./packages/api

# Inside a CI image to verify required language tools exist
aislop doctor
```

## Missing tools

Some engines require external language toolchains:

| Tool                    | Needed for                  |
| ----------------------- | --------------------------- |
| `gofmt`                 | Go formatting               |
| `govulncheck`           | Go dependency audit         |
| `cargo`, `clippy`       | Rust formatting and linting |
| `rubocop`               | Ruby formatting and linting |
| `phpcs`, `php-cs-fixer` | PHP linting and formatting  |

If a tool is missing, aislop skips the matching check and reports why. Install the tool, rerun `aislop doctor`, then rerun `aislop scan`.

<Note>
  `aislop doctor` does not score the project. It checks readiness and coverage only.
