Build real-time applications with PubNub pub/sub messaging. Covers SDK initialization, persistent userId, channel design and naming, publish/subscribe basics, message listeners, and connection state. Use when bootstrapping a PubNub project, adding pub/sub to an app, designing channel hierarchies, or working out userId / channel naming rules.

Deliver real-time sports scores, play-by-play, and scoreboards with PubNub

Create, configure, and deploy PubNub Functions 2.0 event handlers, triggers, and serverless endpoints. Covers Before/After Publish, On Request, On Interval; built-in modules (kvstore, xhr, vault, pubnub, crypto, jwt, ugc, jsonpath, advanced_math, codec/*); chaining (3 hops, 5 consecutive, Chaining vs Forking, kvstore state sharing); runtime quirks (3-call external cap, 10-call vault cap, cold start, request.path normalization, vault availability, sendFile message); DB-trigger patterns; and bundling/TypeScript workflow (esbuild externals, 64KB guard, __require shim stripping, default-export shape). Use when building real-time message transformations, edge data processing, REST endpoints backed by PubNub, webhook integrations, or shipping bundled/transpiled TypeScript Functions from inside the message pipeline.

Builds real-time analytics and automation with PubNub Illuminate. Covers Business Objects (schema), Metrics (aggregations), Decisions (threshold-triggered actions with the 4-step PUT workflow), Queries (ad-hoc vs saved pipelines), and Dashboards. Use when tracking KPIs, building threshold alerts, automating mute/publish/App-Context-update actions, detecting spam or anomalies, or visualizing live activity.

Scale PubNub applications for high-volume real-time events using channel groups, wildcard subscriptions, sharding, and large-event readiness. Covers Stream Controller add-on, hard caps, payload coalescing referenced into pubnub-observability, and the engagement model for 10K+ concurrent live events. Persistence/history is owned by pubnub-history.

Deliver real-time stock quotes and market data with PubNub

Build real-time order tracking and delivery driver systems with PubNub

Real-time presence with PubNub. Covers Admin Portal Presence add-on configuration, join/leave/timeout events, hereNow occupancy, presence state, dropped-connection categories (PNNetworkDownCategory etc.), heartbeat tuning, and multi-device sync for the same userId. Use when implementing online/offline indicators, occupancy counts, last-seen tracking, or troubleshooting presence flapping.

Secure PubNub applications with Access Manager v3, end-to-end AES-256 encryption, TLS 1.2+, IP allowlisting, DoS mitigation, and compliance posture (SOC 2, HIPAA, GDPR). Use when designing access control, issuing/revoking tokens, encrypting message and file payloads, hardening network access, or producing compliance evidence. Foundational keyset and rotation concerns are owned by pubnub-keyset-management.

Build HIPAA-compliant telemedicine apps with PubNub real-time messaging

Build chat applications with PubNub Chat SDK — direct/group conversations, typing indicators, message actions (reactions, edits, read receipts), file sharing, and threaded messages. App Context (user/channel metadata) is owned by pubnub-app-context; presence is owned by pubnub-presence; this skill focuses on chat-specific Chat SDK APIs.

Routes PubNub questions to the correct documentation source, MCP tool, and specialist skill. Classifies intent (chat vs non-chat, conceptual vs implementation, runtime testing vs analytics) and points the agent to the right next step. Use when a user mentions PubNub for the first time, asks "where do I start", "which docs", "what should I use", or any time the appropriate next skill is unclear.

Build real-time betting and casino game platforms with PubNub

Build real-time auction platforms with PubNub bidding and countdowns

Build real-time voting and polling systems with PubNub

Build real-time multiplayer games with PubNub game state sync

Routes PubNub events to external systems with no code via Events & Actions (E&A). Covers event listeners (Messages, Users, Channels, Push, Memberships), action targets (Webhook, SQS, Kinesis, S3, Kafka, IFTTT, AMQP), filter types (basic vs JSONPath), retry policy, envelopes, and batching. Use when integrating PubNub with Lambda, Kafka, SQS, S3, EventBridge, an analytics pipeline, or any external system.

Manages PubNub App Context (Objects API) for users, channels, and memberships. Covers user/channel metadata, custom fields, membership management, querying with filters, and referential integrity. Use when storing user profiles, channel metadata (name, topic, mute flags), tracking who is in which channel, or working with the Objects/App Context API.

Retrieves historical PubNub messages via Message Persistence (Storage & Playback). Covers timetoken-based pagination, per-channel ordering guarantees, offline catch-up flows, retention configuration, and the "catch-up tool not a data lake" principle. Use when fetching past messages, paginating with timetokens, building offline-resume UI, retrieving messages with actions, or configuring retention.

Logging, testing, cost hygiene, incident triage, and usage metrics for PubNub apps. Covers the correlation fields every send/receive must log, the test pyramid for real-time apps, payload + fan-out cost hygiene, the incident triage runbook, and PubNub usage metrics for billing reconciliation. Use during code reviews, when planning monitoring, when triaging incidents, or when investigating PubNub cost overruns.

Cross-cutting reliability patterns for PubNub apps. Covers reconnect with exponential backoff + jitter, idempotent publish with client-generated message IDs, dedup-on-merge for live + history streams, queue-and-retry for offline writes, and schema versioning of message envelopes. Use during design reviews, when planning offline support, or during incident response when network or delivery reliability is the concern.

Manages PubNub apps, keysets, and environment separation. Covers the publish/subscribe/secret key model, dev/staging/prod isolation, key rotation hygiene, demo-key boundaries, and custom origin configuration. Use when setting up a new PubNub project, separating environments, rotating keys, configuring demo or production keysets, or asking about apps, keysets, or custom origins.
