Provenance

Supply chain provenance

Status for the latest visible version.

No SLSA provenance npm registry signatures gitHead linked

Without SLSA provenance there is no cryptographic link between this tarball and the public source — the axios compromise (March 2026) relied on exactly this gap.

Accepted risks

Findings the reviewer chose to accept rather than block on.

SourceRuleReasonAccepted byWhen
semgrep semgrep:dynamic-require AI (semgrep): Dynamic require constructs a platform/arch path to load the native .node addon — standard pattern for native bindings, not a supply-chain risk. ai
dependencies unvetted-dep:node-gyp-build AI (dependencies): node-gyp-build is the standard native addon binary loader; its use here is expected and appropriate. ai
install-scripts install-script:install AI (install-scripts): node-gyp-build is the canonical install script for native Node.js addons shipping prebuilts; stable and expected for tree-sitter across all versions. ai
npm-metadata bundled-binaries AI (npm-metadata): Prebuilt .node binaries for major platforms are the documented output of prebuildify; expected for this native addon package. ai
semgrep semgrep:eval-usage AI (semgrep): eval() is used to create dynamically-named SyntaxNode subclasses from grammar type names — a legitimate pattern, not external input. Not a supply-chain risk. ai
phantom-deps phantom-dep:node-addon-api AI (phantom-deps): node-addon-api is referenced in binding.gyp for native compilation, not JS imports — standard N-API addon pattern. ai

v0.25.0

2 findings
HIGH Package has 'install' script install-scripts

Script: node-gyp-build

LOW No provenance attestation provenance

Package was published without Sigstore provenance. Only ~12% of npm packages have provenance, so this is common but not ideal.

v0.21.1

3 findings
HIGH Package has 'install' script install-scripts

HIGH Bundled binary files (4) npm-metadata

Package contains compiled binaries that could be backdoors: • prebuilds/darwin-arm64/tree-sitter.node • prebuilds/darwin-x64/tree-sitter.node • prebuilds/linux-x64/tree-sitter.node • prebuilds/win32-x64/tree-sitter.node
