Overview

You select the chart runtime or Squillify Mono contract and receive its sealed manifest, exact digests, licences, configured public origin and absolute content-addressed URLs. The origin remains outside certified chart-envelope digests, so hosts can migrate it without recertifying charts. You receive metadata only; the resolver does not return binary assets, generate charts, fetch URLs or execute JavaScript.

Interactive chart behavior depends on exact shared runtime and font bytes. The resolver returns their immutable metadata and current absolute delivery URLs without embedding binaries or an origin inside every chart envelope.

Reliability

STRICT and deterministic. All returned paths are generated from sealed allowlisted manifests. RUNTIME_CONTRACT_UNKNOWN means the requested resource name is unavailable. RUNTIME_REQUIREMENT_MISMATCH means an expected version or digest differs from the sealed release. RUNTIME_PUBLIC_ORIGIN_UNAVAILABLE means the platform delivery origin is missing or invalid and the same request may be retried after operator configuration. URLs use anonymous GET with credentials omitted and are never file references. Browsers must still verify byte length and SHA-256 before installing or executing downloads.

Context footprint

Responses contain bounded metadata only. Binary JavaScript, CSS, font and licence bytes are fetched once from the configured public origin. A successful call costs 1 execution credit.

When to use it

After a Squillify chart response declares a runtime or font requirement and you need its sealed manifest or public content-addressed paths.

When the required contract/version/digest is already cached, or when you need to create a chart rather than resolve its shared resources.

Scope

Note

Resolves one immutable Squillify chart resource manifest and its public paths.

How we handle your data

Sensitive output possible

What this means

This skill may receive sensitive content and may return submitted, transformed, extracted, or reformatted content.

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 may contain submitted or transformed 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.

Input schema

Field	Type	Required	Description
requirement	object	No	Preferred object form with contract, version and manifestSha256 properties. When omitted, supply the legacy flat contract fields instead.
contract	string	No	Legacy flat form: chart-runtime or squillify-mono. Omit when requirement is supplied.
expectedVersion	string	No	Legacy flat form exact version pin; omit when requirement is supplied.
expectedManifestSha256	string	No	Legacy flat form exact manifest pin; omit when requirement is supplied.

Output schema

Field	Type	Required	Description
contract	string	Yes	Caller-facing resource alias that was resolved.
version	string	Yes	Exact semantic resource version.
license	object	Yes	Licence object with the governing identifier and the exact notice asset filename.
manifestSha256	string	Yes	SHA-256 of the exact public manifest bytes, not of this enriched skill response.
manifestPath	string	Yes	Content-addressed manifest path relative to origin.
origin	string	Yes	Configured public origin supplied by the platform.
requirement	object	Yes	Exact resolved requirement object with contract, version and manifestSha256 properties; copy this shape for pinned re-resolution.
access	object	Yes	Top-level access object whose method, authentication, credentials and fileRef properties apply to every returned public URL.
manifestResource	object	Yes	Public manifest resource with absolute URL, relative path, digest, byte length, content type and anonymous-GET access properties.
cacheKey	string	Yes	Stable resource cache key.
cacheKeyFormula	string	Yes	Normative cache-key derivation.
assetsDigest	string	Yes	SHA-256 of the canonical manifest asset table.
assets	array	Yes	Array of 1..32 immutable resource objects; each item carries name, file, role, contentType, bytes, sha256, path, url and access.
thirdParty	boolean	No	True when the resource bytes originate from a third party.
familyAlias	string	No	Installed font-family alias.
upstreamFamily	string	No	Original upstream font family.
upstreamPackage	string	No	Pinned upstream package identity.
provenance	string	No	Pinned upstream package URL.
noLocal	boolean	No	True when local font substitution is forbidden.
faces	array	No	Array of 1..8 deterministic font face objects with asset, weight and style properties; present only for the font resource.
