## What is Double Agent?

Double Agent pulls all ecosystem PRs from the x402 GitHub registry
(github.com/coinbase/x402/pulls, label=ecosystem), enriches each entry with domain
signals (agent-card.json, llms.txt, resolved.sh presence), GitHub author metadata, and
category classification. The dataset is updated weekly and published here for agent and
human consumption.

Source: 311+ ecosystem-labeled PRs across open, merged, closed, draft, and rejected
statuses. Growing continuously.
