Constructive Realtime

Real-time data delivery via GraphQL subscriptions, live queries, and change tracking.

When to Apply

Use this skill when:

Adding real-time subscriptions to a Constructive app
Working with PostGraphile live queries
Implementing change tracking and notifications
Using WebSocket connections for real-time updates
Using ephemeral realtime for high-frequency signals (cursors, presence, live indicators)

Core Concepts

GraphQL Subscriptions

PostGraphile v5 provides built-in subscription support via WebSocket (graphql-ws protocol). Subscriptions are automatically generated for any table with appropriate grants.

Live Queries

PostGraphile's @stream and @live directives enable:

Live queries — auto-refresh results when underlying data changes
Streaming — progressive delivery of large result sets

Change Tracking

The change_log system records row-level changes (INSERT, UPDATE, DELETE) that power both subscriptions and audit trails.

Ephemeral Realtime

DataRealtime({ ephemeral: true }) bypasses change_log entirely — events go straight from trigger → pg_notify → WebSocket with zero write overhead. Designed for high-frequency signals (cursor positions, presence indicators, live typing) where durability isn't needed.

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).

AI — agent module, LLM providers, RAG pipelines, embeddings, agentic-kit multi-provider client, Search* blueprint nodes (SearchUnified, SearchVector), ProcessFileEmbedding/ProcessImageEmbedding/ProcessChunks. Use when asked to 'add AI search', 'build RAG pipeline', 'embedding worker', 'agentic-kit', 'LLM integration', 'Ollama', 'Anthropic', 'OpenAI', 'file embedding', 'image embedding', 'chunking', 'SearchUnified', 'SearchVector', 'multiplayer agents', 'shared agents', 'multi-agent', 'agent_id', or when working with AI features in blueprints.

constructive-auth

constructive-io/constructive-skills

Identity, login, sessions, MFA, devices, identity linking — auth flow (sign-up/sign-in/JWT), auth settings (MFA, anonymous sessions, CAPTCHA, cookie auth, rate limits), device settings (tracking, trusted devices, approval gate), identity linking (link_identity, account collision resolution, allow_link_by_email, primary auth method), and service-level auth config. Use when asked to 'sign up', 'sign in', 'auth flow', 'MFA', 'magic link', 'passkeys', 'device approval', 'trusted devices', 'session management', 'cookie auth', 'anonymous sessions', 'CAPTCHA', 'rate limits', 'bootstrap user', 'JWT', 'link identity', 'identity linking', 'account collision', 'allow_link_by_email', 'primary auth method', 'connected accounts', or when working with authentication.
