Best AI Agent for DeepSeek
One answer, based only on verified runs: Claude Code — the only harness with real-run evidence today.
Verdict
Based on verified data only: Claude Code (4 runs, 75%, run-verified). Every other harness is source-only until AgentRunDB runs complete.
The data
| Agent | Status | Runs | Rate |
|---|---|---|---|
| Claude Code | ⚠ Partial — run verified | 4 | 75% |
| DeepSeek Harness (dsh) | Source only — official repo | 0 | — |
| Codex / OpenCode / Cline / OpenClaw / Pi / Qwen Code | Source only | 0 | — |
Why not the others?
DeepSeek Harness (dsh) is the newest entry — 145k+ stars on GitHub within weeks, but AgentRunDB has not run it through a standard test yet. For everything else: not because they are worse, but because they are unverified. AgentRunDB only recommends what it has actually run. Check back as verification batches land.
