Struct ToolSpec 

pub struct ToolSpec {
    pub name: &'static str,
    pub command: &'static [&'static str],
    pub local_paths: &'static [&'static str],
    pub config_files: &'static [&'static str],
    pub output_format: &'static str,
    pub diagnostics_stream: &'static str,
    pub accepts_files: bool,
}

A deterministic checker for one language.

Attributes: name: Tool name, used in logs and finding provenance. command: argv to run, minus the files. The first element is resolved against local_paths before PATH. local_paths: Repo-relative locations to prefer over PATH, so a project gets the version its own CI runs (node_modules/.bin/eslint rather than whatever is installed globally). config_files: Repo-relative paths that mean “this project has opted into this tool”. A tool with none of them present is skipped: its defaults are not the project’s chosen style, so running it anyway would invent findings the project never asked for. output_format: How to parse the tool’s diagnostics into findings. diagnostics_stream: Which stream carries them. go vet writes to stderr, so reading only stdout would report every Go file clean.

Fields

name: &'static str

Tool name, used in logs and finding provenance.

command: &'static [&'static str]

argv to run, minus the files. The first element is resolved against local_paths before PATH.

local_paths: &'static [&'static str]

Repo-relative locations to prefer over PATH, so a project gets the version its own CI runs (node_modules/.bin/eslint rather than whatever is installed globally).

config_files: &'static [&'static str]

Repo-relative paths that mean “this project has opted into this tool”. A tool with none of them present is skipped: its defaults are not the project’s chosen style, so running it anyway would invent findings the project never asked for.

output_format: &'static str

How to parse the tool’s diagnostics into findings.

diagnostics_stream: &'static str

Which stream carries them. go vet writes to stderr, so reading only stdout would report every Go file clean.

accepts_files: bool

Whether the tool accepts file paths as arguments.

cargo clippy does not: it checks a crate, and a path argument is rejected outright with “unexpected argument”. Appending files to it therefore made every run fail, so every Rust file came back Unavailable and drep check exited 2 on any Rust repository - the deterministic half for Rust never ran at all.

A tool with accepts_files: false is invoked bare and reports on the whole project, so its findings are filtered down to the files actually being checked. Without that filter a commit gate would block on pre-existing issues in code the commit never touched.
