Build a polished, self-contained HTML application that lives inside an SG/Send vault and renders from index.html — a photo gallery, strategy microsite, dashboard, report, journal, or any single-page experience. Use this whenever the user wants to create a vault app, build an HTML app for a vault, make a website inside a vault, render a page from a vault, or auto-open a vault as an app — even when they only describe the content (gallery, report, microsite, slide deck, form, presentation) without saying "app". Covers the authoring contract all vault HTML must follow, the data-plus-app project shape that works, the patterns that survive both the SG/App host and the vault browser preview, the sgit commit-and-push workflow, and cross-references the canonical window.sg API reference (library/guides/vault-html/AUTHORING.md) and the sg-playwright screenshot guide.
Use this skill whenever you need to interact with a zero-knowledge encrypted vault via sgit (formerly sg-send-cli). Triggers include: creating a vault, committing changes, pushing files to a vault, pulling changes, cloning a vault, checking vault status, branching, sharing snapshots via tokens, diffing, stashing, reverting, exporting, publishing, or any mention of sgit, SG/Send, encrypted vault, vault key, Simple Token, or encrypted vault sync. This skill enables persistent state and bidirectional communication between Claude sessions and human collaborators through a shared zero-knowledge encrypted object store with git-like versioning.
Drive the SG/Playwright browser-automation service over HTTP — navigate pages, run scripted multi-step sequences, take screenshots/PDFs, extract DOM/text/HTML, batch-probe one page from many angles, or hold a stateful browser session. Trigger when the user asks to "navigate to a URL", "take a screenshot of a page", "scrape a page", "fill a form on a site", "extract the DOM from", "render a PDF of", "click a button on", "drive a browser", or any phrasing that means "remote-control a real Chromium instance through the sg-playwright API". The launching operator gives you a HOST (the FQDN of an ephemeral sg-compute EC2 / a /pw vault proxy) and a TOKEN; every call is HTTP — you hold no browser yourself. CRITICAL on auth: use `x-sgraph-access-token: ${TOKEN}` for `${HOST}/pw/...` (the proxied production path) and `X-API-Key: ${TOKEN}` for direct stack access — sending the wrong header gets 401 on every call.
Use this skill whenever the user wants to create infographics, slide decks, visual presentations, or image-based content using the SGraph infographic generator API. Triggers include: any mention of 'infographic', 'slide deck', 'slides', 'visual summary', 'presentation images', 'deck from document', 'generate slides', or requests to turn a document/brief into visual slides or infographics. Also triggers when the user mentions 'dev.tools.sgraph.ai', 'infographic-gen', or 'OpenRouter' in the context of image generation. Use this skill even if the user just says 'make me a deck' or 'visualise this document' — anything that implies AI-generated infographic images. Do NOT use for standard PowerPoint (.pptx) creation without AI image generation, or for diagrams/charts that can be handled by code-based visualisation tools.
Use this skill whenever you need to create, edit, or structure content inside an SG/Send encrypted vault — including writing _page.json page layouts, markdown documents, folder navigation, or any vault file structure intended to be browsed via send.sgraph.ai. Triggers include: "create a vault page", "add a _page.json", "build a hub page", "make a slideshow", "author vault content", "write a page layout", "create a gallery", "add navigation to the vault", "build an article", "write markdown for the vault", or any request to create or improve structured content inside an sgit vault. Does NOT require cloning the SGraph-AI__App__Send repo — the full schema reference is embedded in this skill.
Use this skill whenever the user wants to talk to the SGraph Send agentic team, interact with an SG/Send team agent, start a team session, or mentions "talk to the team", "Conductor", "Sherpa", "AppSec", "Architect", "Dev", "Ambassador", "Librarian", "Cartographer", or any SGraph Send agent role. Also trigger when the user asks about the SGraph Send product, its security model, its codebase, onboarding experience, or any aspect of SG/Send that would benefit from an agent-grounded response. This skill bootstraps a full agentic team session: cloning the repo, reading the grounding documents (reality files, role definitions, debriefs), and becoming the Conductor who can embody any of the 18+ specialised agents.
Zero-knowledge encrypted file transfer via SG/Send MCP with optional email delivery via n8n. Use this skill whenever the user wants to send a file securely, encrypt and upload a file, share an encrypted document, send a file via SG/Send, or email an encrypted download link. Also trigger when the user mentions "SG/Send", "sgraph", "zero-knowledge file transfer", "encrypted send", or asks to "send a file securely" or "encrypt and email a file". This skill handles the full pipeline: file creation, SGMETA envelope wrapping, AES-256-GCM encryption, upload to SG/Send via MCP, round-trip verification, download URL construction, and optional email delivery via n8n Sherpa WorkMail.
