Backend &amp; API

extension-email

Support for sending service/transactional emails. Don't use this for sending marketing emails or verification emails.

extension-http-outcalls

HTTP outcalls performed by the backend canister (not in the frontend).

extension-data-viewer

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.

openclaw-backup

Encrypted backup and restore for OpenClaw Agent workspace files (SOUL.md, MEMORY.md, IDENTITY.md, AGENTS.md, TOOLS.md). Uses tar + openssl (AES-256-CBC) encryption and soul-upload.com API. Auto-generates a new random password for each backup (DO NOT reuse passwords). Use when the user needs to: (1) Back up or upload agent workspace files, (2) Restore or download a previous backup, (3) Delete a backup from remote storage, or (4) Manage encrypted agent persistence.

video-edit

Edit existing video on RunComfy — this skill is a smart router that matches the user's intent to the right edit model in the RunComfy catalog. Picks Wan 2.7 Edit-Video (general restyle / background swap / packaging swap, identity + motion preservation), Kling 2.6 Pro Motion Control (transfer precise motion from a reference video to a target character), or Lucy Edit Restyle (lightweight identity-stable restyle / outfit swap). Bundles each model's documented prompting patterns so the skill gets sharper edits without burning iterations on the wrong model. Calls `runcomfy run <vendor>/<model>/<endpoint>` through the local RunComfy CLI. Triggers on "video edit", "edit video", "restyle video", "swap video background", "motion control", "outfit swap video", or any explicit ask to transform a video.

genmedia-labs

setup-sandbox

Set up the initial file system for a new sandbox. Fetches the account's organizations and artists via the Recoup CLI and scaffolds the folder structure. Use when a sandbox has just been created and has no existing file system. Before running, check if the sandbox already has an orgs/ directory — if it does, this skill is not needed.

blackforge

Answer crypto market-data questions with BlackForge. Use this skill whenever the user asks about order-book or trade data for a coin on a spot venue — its latest stats on an exchange, order-book depth or resting/pulled liquidity for a pair, taker buy-vs-sell volume, order-ladder rungs, price-level lifetime, trade timing, outsized trades, or market-cap/attention enrichment; when they want to pull, chart or compare a metric over a time range; or when they ask which pairs a venue lists. Covers 9 spot exchanges (binance, bitget, bybit, coinbase, gate, kraken, kucoin, mexc, okx) and ~11,800 spot pairs — 120 measurement columns per pair per closed 5-minute window. Trigger even when BlackForge is not named but the question is about crypto market data on a venue. Drives the BlackForge MCP tools (blackforge_catalog / blackforge_symbols / blackforge_latest / blackforge_series / blackforge_usage) or the `blackforge` CLI; never reimplements the API. Every returned column is a measurement, not a trade call.

connector-googledrive

MANDATORY recipe for every Caffeine build that lists, reads, creates, shares, or organizes files and folders on the user's own Google Drive. The ONLY supported path is the `googledrive-client` mops package (Drive REST API v3) combined with the `google-oauth` mops package (OAuth 2.0 token exchange + refresh + PKCE). Hand-rolling `ic.http_request` calls to `oauth2.googleapis.com` or `www.googleapis.com/drive/v3` is a FORBIDDEN anti-pattern — it bypasses bearer auth, the `is_replicated = ?false` replication-cost safeguard, and the `google-oauth` library's token handling. Load this skill ONLY when the user, spec, or a prior task refers to **Google Drive specifically** — e.g. "Google Drive", "my Drive", "Drive files/folders", a Drive file/folder ID or share link, "upload to Google Drive", "list my Drive files", or Drive sharing/permissions. Do NOT load it for generic file storage, documents, uploads, or access-control features that are not Google Drive — those are unrelated and this connector must not be attached to them. When it does apply, load it BEFORE writing any code that touches a Google endpoint.
