FilingBrief Starter — 3 SEC-Analysis Skills for Claude & ChatGPT
Read SEC filings in minutes, not hours.Filingbrief Starter is three foundational skills that turn Claude or ChatGPT into a disciplined SEC-filing reader. You drop in a 10-K, an earnings call transcript, or a ticker — you get a structured, citation-first brief in minutes.This is the entry-level pack. Most buyers eventually upgrade to Complete (8 skills, $97), but Starter is enough to dramatically change how you do due diligence on a single stock. What's inside📄 10-K AnalyzerTurns a 200-page annual report into a ranked-risk brief with page citations. Surfaces what changed vs the prior year. Reads in 3 minutes. Replaces the 4 hours you'd spend reading the filing by hand.📞 Earnings Call DigestCompresses a 60-minute earnings call into a 3-minute structured digest. TL;DR in 5 bullets, guidance with directions (raised / lowered / reaffirmed), tone shifts with verbatim quotes, Q&A signals — including the questions management refused to answer.🔍 Insider Trades ScannerLive SEC Form 4 scanner. Pulls insider transactions for any US-listed ticker, separates open-market buying (P) from RSU mechanics (F, A, M), detects 10b5-1 plans, surfaces clustered buying. Gives you a defensible signal level — not a vague "insiders are bullish". Each skill ships in two formats- Claude Skills (native) — drop the folder into Claude.ai (Settings → Skills) or ~/.claude/skills/ for Claude Code. Skills trigger automatically when you ask the right question.- ChatGPT Project Instructions — self-contained markdown you paste into a ChatGPT Project. No external files. No setup beyond the paste. Why FilingBrief, not just ChatGPT?Generic ChatGPT will happily invent page numbers, hallucinate revenue figures, and recommend buy/sell calls it has no business making. FilingBrief is a disciplined wrapper: built-in anti-hallucination checklists, citation requirements, signal-rating rules, and an explicit boundary against investment recommendations.You pay once. You install in 3 minutes. You read every 10-K from now on in 5 minutes instead of 5 hours.What you get (digital download)A single zip file containing:✅ 3 Claude skill folders (10-K Analyzer · Earnings Call Digest · Insider Trades Scanner)✅ 3 self-contained ChatGPT-Project versions✅ The Python script fetch_form4.py (for Insider Trades Scanner — stdlib only, no installs)✅ README and INSTALL guide (bilingual EN/FR)✅ Methodology references for each skill✅ Lifetime updates on these 3 skillsTotal size: ~30 KB.
