SEC Rule Draft Diff and Material-Change Flagger

Keeps a running snapshot of a specific SEC proposed-rule page. On each run it re-scrapes the page, compares the fresh text to the previously stored version, and surfaces exactly what changed. An LLM judges whether the edits are substantive (new obligations, changed thresholds, altered effective dates) or cosmetic (formatting, typos), then sends a Slack message with the verdict and the diffed passages.

Use it when your team tracks a handful of in-flight SEC rulemakings and cannot afford to manually re-read 80-page documents to find the two sentences that moved. Best for compliance, legal, and policy teams who need a same-day heads-up the moment a draft is revised.

1. 1A scheduled trigger fires every few hours.
2. 2Firecrawl scrapes the watched rule page to clean markdown.
3. 3The pipeline pulls the prior captured version from Postgres and computes a text diff; if nothing changed it stops.
4. 4OpenAI reads the diff and classifies it as material or cosmetic with a one-line rationale.
5. 5The new version is written back to Postgres as the baseline.
6. 6Slack receives an alert tagged by severity with the changed passages inline.
