Uploads, buckets, presigned URLs, file lifecycle — presigned URL flow (requestUploadUrl → PUT → downloadUrl), bucket provisioning, upload-client, public/private/entity-scoped buckets, MIME type restrictions, file size limits, and deduplication. Use when asked to 'upload files', 'add file uploads', 'configure storage', 'set up MinIO', 'presigned URLs', 'download URLs', 'bucket provisioning', or when working with storage plugins.

Constructive Storage

Complete file upload pipeline using presigned S3 URLs — the client uploads directly to S3/MinIO, never routing file bytes through the GraphQL server.

When to Apply

Use this skill when:

Adding file uploads to a Constructive app
Configuring buckets (public, private, entity-scoped)
Working with presigned URLs for upload and download
Setting MIME type restrictions and file size limits
Implementing file deduplication
Using the @constructive-io/upload-client library

  |                            |                         |

  |-- downloadUrl query ------>|-- presigned GET URL ---->|
  |<-- signed download URL ----|                         |

Packages

Package	Purpose
`graphile-presigned-url-plugin`	`requestUploadUrl` mutation, `downloadUrl` computed field
`graphile-bucket-provisioner-plugin`	Auto-provisions S3 buckets on row creation
`graphile-upload-plugin`	GraphQL `Upload` scalar for stream-based uploads
`@constructive-io/upload-client`	Client orchestrator: hash → requestUploadUrl → PUT
`@constructive-io/bucket-provisioner`	Low-level S3 bucket provisioner (CORS, policies, lifecycle)

Bucket Types

Type	`is_public`	RLS	Use Case
Public	`true`	Minimal	Marketing assets, public images
Private	`false`	Full	User documents, sensitive files
Entity-scoped	`false`	Entity membership	Per-org/team file storage

Entity-scoped buckets are provisioned via has_storage: true on entity types — see constructive-entities.

constructive-features

constructive-io/constructive-skills

Feature catalog for Constructive apps — one scannable index of every capability (auth methods, authorization, multi-tenancy, data modeling, storage, search, AI, GraphQL, ops) with pointers to the authoritative skill or toggle that owns it. Use when asked "what can a Constructive app do", "what features are available", "which skill covers X", "is there built-in support for Y", "how do I enable read-only mode / magic links / passkeys / SSO / pgvector / search / uploads", or when orienting to the platform for the first time.

constructive-security

constructive-io/constructive-skills

Authorization — Safegres protocol, 23 Authz* policy types, RLS, grants, permissions, permission defaults, GuardStepUp, read-only access, storage policies, and the secureTableProvision workflow. Use when asked to 'add security', 'RLS', 'grants', 'policies', 'Safegres', 'Authz*', 'AuthzEntityMembership', 'AuthzDirectOwner', 'AuthzMemberOwner', 'AuthzComposite', 'AuthzSystemOnly', 'AuthzHumanOnly', 'AuthzValueAllowed', 'AuthzValueExists', 'AuthzValueMatch', 'system-only policy', 'system-only writes', 'human-only mutation', 'block agents from writing', 'read-only mode', 'secure table provision', 'storage policies', 'bucket security', 'permission model', 'permission defaults', 'default_permissions', 'GuardStepUp', 'step-up auth', 'guard step-up', 'require step-up', 'MFA guard', 'named permissions', or when working with authorization in blueprints or the ORM.

constructive-builder

constructive-io/constructive-skills

Build a Constructive app end-to-end from a brief. Use when asked to build/scaffold an app on Constructive, create a CRUD app, provision a data model with RLS, wire Blocks + auth flows, or verify an app with Chrome QA / agent-browser — keep time-to-app under 10 minutes on a warm hub. Drives the four mainline phases (1 Backend Up, 2 Data Model Provisioned, 3 Frontend + SDK, 4 UI / Blocks) and supports the three policy tiers: owner-scoped, public-read + owner-write, and b2b org-membership. Triggers: "build a Constructive app", "scaffold an app on Constructive", "provision a data model with RLS", "wire Blocks and auth flows", "verify the app with agent-browser". Builds ANY CRUD app generically from a brief — it is NOT for editing the Constructive platform itself (constructive / constructive-db).
