Overview

When you need a yes-or-no answer on version compatibility, we parse your version and range under the grammar you pick — strict SemVer 2.0.0 comparators or npm-style caret, tilde, hyphen, and x-ranges. Build metadata never affects precedence; you control whether prereleases count. We do not resolve dependency trees or pick versions from a registry — do not use this when you need installation or resolution.

SemVer and npm range rules are easy to get wrong by hand. We apply the same precedence rules every time so your gates stay consistent.

Reliability

STRICT and deterministic for identical inputs. Domain errors (not retryable; fix the input — unchanged retry will not succeed): INVALID_SEMVER (version is not valid SemVer — send a well-formed version); INVALID_SEMVER_RANGE (range cannot be parsed — fix the range syntax); SEMVER_RANGE_TOO_COMPLEX (range exceeds complexity limits — simplify the range); SEMVER_GRAMMAR_UNSUPPORTED (grammar is not semver_2 or npm — pick a supported grammar).

Context footprint

Returns satisfies, normalized version/range, an optional reason, and small _meta. A successful call costs 1 execution credit.

When to use it

When you have a concrete version and range and need a deterministic satisfies answer.

When you need to resolve, install, or pick versions from a registry.

Scope

Note

Tests whether a version satisfies a range under the grammar you choose.

Non-goals

How we handle your data

Sensitive input, safe output

What this means

This skill may receive sensitive content, but it does not target sensitive data and returns only a structured non-sensitive result.

Squillify guarantees

Runs inside Squillify
This skill runs inside Squillify.
Payloads are not sent to an external service by this skill.
Squillify does not permanently store submitted payloads.
Telemetry records metadata only, not submitted content.
Submitted payloads are not used for training.
Submitted payloads are not reviewed by humans.
This skill does not target sensitive data.
The response does not contain submitted content.

Your responsibility

Squillify does not determine whether submitted content is sensitive. Your application is responsible for deciding what data it is allowed to submit. Your application is responsible for securing the response.

satisfies	boolean	Yes	Whether the version satisfies the range.
normalizedVersion	string	Yes	Canonical rendering of the tested version.
normalizedRange	string	Yes	Canonical comparator-set rendering of the range.
reason	string	No	Stable negative-verdict reason; omitted when satisfied.
comparatorSetCount	integer	Yes	Number of OR-separated comparator sets.
_meta	object	Yes	Closed applied grammar-version receipt naming npm-compatible-1 or semver-2.0.0.
