earnings-preview-single

Earnings-preview-single generates a concise, professional equity-research earnings preview for a single company, producing a self-contained HTML report targeting four to five printed pages that is dense with figures and tight narrative. It solves the problem of assembling a rigorous, sourced pre-earnings brief — covering the most recent transcript, competitor landscape, valuation, and recent news — without the errors that come from working from memory or unverified sources.

The skill is built around strict discipline. It permits only two data sources — Kensho Grounding MCP (`search`) and S&P Global MCP (`kfinance`) — and explicitly forbids any generic web search, browser, or scraping tool, even as a fallback. It mandates a research-before-writing sequence across numbered phases (company profile, transcript analysis, and more), and requires writing every raw MCP result to intermediate files under a temp directory immediately after each call, then reading those files back as the single source of truth before building the report. Additional rules enforce correctness: never infer fiscal quarter from calendar date, keep the report concise with punchy bullets, use only verbatim management quotes in blockquotes, verify every multi-step calculation, label all valuation ratios explicitly as LTM or NTM, and wrap every claim — numeric and qualitative — in an anchor hyperlink to a numbered appendix reference so each figure is traceable.

It targets equity analysts, investment professionals, and finance teams (it is a partner-built S&P Global plugin skill) who need a fast, auditable, single-name earnings preview. Behaviorally it is a read-only research-and-reporting workflow that only writes local scratch files and an HTML output.
