Hunt high-value Pokémon cards on eBay overnight
Community report: alessio Finelli gave the Codex agent a sparse skill file with rules on target cards, batch size of 5, and grading companies. The agent browses eBay listings on its own, pulls PSA certificate numbers, cross-references known prices, and flags underpriced high-value cards. It works as his power buyer, surfacing underpriced cards before others see them.

It is one of 196 sightings filed under Productivity on Agent Sightings (number 176 by interest), and one of 32 involving Codex.
