Route challenge: dual-agent, double-verified

Route challenge: dual-agent, double-verified

Points: 200 · Type: project · Evidence: objective (verify.py)

The final challenge of the Foundation path: prove you can drive two different agents through the same task — and verify both results yourself.

The task

Pick a real small task you care about (suggestion: “a CLI that counts the lines, words, and bytes of a file” or reuse any scenario skin from the path courses: hands-on-python-with-claude-code, hands-on-with-openai-codex, hands-on-with-cursor, hands-on-with-deepseek-harness, hands-on-with-kimi-code, hands-on-with-zcode, agent-rules-single-source, verifying-ai-generated-code).

Choose any two of the six agent tools this path teaches (Claude Code, Codex app, Cursor, DeepSeek Harness, Kimi Code, ZCode). Then:

1. Round one — agent A. In a fresh folder, write a TASK.md describing the contract (inputs, outputs, edge cases, done = tests pass), drive your first agent to implement it, and add a verify.py-style check that passes on the result.
2. Round two — agent B. Same task, fresh folder, same TASK.md. Drive a different agent to implement it independently — do not copy round one’s code.
3. Double verification. Run your objective check against both implementations. Record what differed: structure, edge-case handling, test coverage, anything that surprised you.

What to record

• Both folders kept intact (they are your evidence).
• A short note: which agent’s output needed fewer corrections, and why you believe that — this is the skeptical-review habit from the verifying-ai-generated-code course applied across tools.

Checkpoint

Complete when:

• Both implementations exist and your objective check passes on each.
• Your comparison note names at least one concrete difference with evidence (a file, a test, a command output).
• The two agents were genuinely different tools — not two sessions of the same one.

The claim for this challenge is recorded against the Foundation path badge — 200 points toward Agent User. Self-reported evidence, never a certificate.
