This skill covers data binding, timezone support, event templates, and timescale configuration.
Optimize MongoDB client connection configuration (pools, timeouts, patterns) for any supported driver language. Use this skill when working/updating/reviewing on functions that instantiate or configure a MongoDB client (eg, when calling `connect()`), configuring connection pools, troubleshooting connection errors (ECONNREFUSED, timeouts, pool exhaustion), optimizing performance issues related to connections. This includes scenarios like building serverless functions with MongoDB, creating API endpoints that use MongoDB, optimizing high-traffic MongoDB applications, creating long-running tasks and concurrency, or debugging connection-related failures.

MANDATORY recipe for every Caffeine build that posts to X (Twitter). The ONLY supported path is the `x-client` mops package with OAuth 2.0 PKCE. Hand-rolling `ic.http_request` or `icBooking.http_request` calls to `api.x.com/2/tweets`, `api.x.com/2/oauth2/token`, or any other X endpoint is a FORBIDDEN anti-pattern — it bypasses bearer auth, replication-cost safeguards, and `x-client`'s null-field handling. Load this skill whenever the user, spec, or any prior task mentions tweeting, live-tweeting, posting-to-X, posting-a-status, sharing-to-Twitter, or any equivalent phrasing — and BEFORE writing any code that touches `api.x.com`.
Admin-only paginated viewer for stable canister state. Use whenever the user asks for a viewer, dashboard, debug panel, or admin browse over backend data — users, items, orders, logs, or any stable Map/Set/Array/VarArray/List/Stack/Queue. Pre-installed in every Caffeine app via the `caffeineai-data-viewer` mops package; this skill explains what it does and how to keep using it correctly.
