GOAL
Have the agent review local code changes to merchantscroll's Pauper deck data and stats code, flagging any bugs introduced by the diff before it reaches production.
- +0Prompt · +0Review these local code changes carefully and report every bug introduced by the diff, even at the cost of false positives.
- +0mAgent did · +0mGrepped for recent_entries/site_name patterns and read deck JSON files (gruul-ponza.json, altar-tron.json) plus deck_stats.py to understand how deck entries are consumed.
- +0mAgent did · +0mSearched the whole repo for specific player/tournament identifiers (Ixidor29, GLAM_, Maccaciock) and cross-checked against tests (test_unit.py) and rebuild_deck_profiles/deck_stats usage.
- +0mAgent did · +0mRead utils.py to check canonical_starttime logic and grepped tests for site_name/date and recent_entries handling.
- +0mAgent did · +0mContinued reading test_unit.py sections and searched frontend files and docs for recent_entries/top_pilots references to confirm expected data shape.
- +0mAgent did · +0mRead deck-profile.md docs, grepped for 9-0/Ixidor29 patterns in Python files, and inspected player_stats.py to confirm how the missing entry would affect displayed stats.
- +0mOutcome · +0mReported one high-severity bug: the diff drops Ixidor29's 2026-07-23 Pauper Challenge 9-0 first-place result from gruul-ponza.json's recent_entries.
VERDICT
Next time I'd point the agent straight at the diff hunks instead of letting it re-derive context by grepping the whole repo for identifiers. Reading deck_stats.py and the docs early was what actually let it catch that a strong Ixidor29 result had silently disappeared from recent_entries.
