# Build Report — agentkit-cli v0.61.0

**Date:** 2026-03-19
**Feature:** `agentkit user-duel`
**Status:** COMPLETE

## Summary

Built `agentkit user-duel github:<user1> github:<user2>` — a head-to-head agent-readiness comparison between two GitHub developers. Each user's public repos are scored via `UserScorecardEngine`, then compared side-by-side with winner declared per dimension.

## Deliverables Completed

### D1: UserDuelEngine core (`agentkit_cli/user_duel.py`)
- `UserDuelResult` dataclass with full schema and `to_dict()`
- `DuelDimension` dataclass with per-dimension winner tracking
- `UserDuelEngine.run(user1, user2)` → `UserDuelResult`
- Four dimensions: avg_score, letter_grade, repo_count, agent_ready_repos
- Overall winner: majority of dimension wins (tie if equal)
- `_engine_factory` test override for mocked testing
- 16 tests added

### D2: `agentkit user-duel` CLI command (`agentkit_cli/commands/user_duel_cmd.py`)
- Wired into `agentkit_cli/main.py` as `user-duel` command
- Flags: `--limit N`, `--json`, `--share`, `--quiet`, `--timeout`, `--token`
- Rich terminal table output with dimension breakdown
- Verdict banner: "🏆 @user1 wins!" or "🤝 Tied!"
- Progress display while fetching
- 12 tests added

### D3: Dark-theme HTML duel report (`UserDuelReportRenderer` in `user_duel.py`)
- `#0d1117` dark background, GitHub avatar integration
- Side-by-side combatants header with grade badges
- Dimension table with winner highlights (green/dim styling)
- Per-user top-5 repo cards with scores, grades, and context markers
- Overall winner/tie banner
- `publish_user_duel()` for here.now upload via `--share`
- 10 tests added

### D4: Integration with `agentkit run` and `agentkit report`
- `--user-duel user1:user2` flag on `agentkit run`
- Duel result included in JSON output when `--user-duel` specified
- `--user-duel user1:user2` flag on `agentkit report`
- Graceful error handling in both commands
- 8 tests added

### D5: Docs, CHANGELOG, BUILD-REPORT
- `CHANGELOG.md`: v0.61.0 entry added at top (above v0.60.0)
- `README.md`: `agentkit user-duel` added to commands table and new "User Duel" usage section
- `BUILD-REPORT-v0.61.0.md`: this file
- 9 doc-validation tests added
