Suggestion: add AMAP-ML/LongHorizon-Harness

[Upper9527]

Hi, I'd like to suggest LongHorizon-Harness for inclusion in awesome-claude-skills.

Repo:
https://github.com/AMAP-ML/LongHorizon-Harness

Why it seems relevant here:

• open-source Python harness for long-running GUI and CLI tasks
• runs around Claude Code or Codex instead of replacing their native agent loops
• separates Manager, fresh-context Executor, and independent Auditor roles
• keeps only verified progress in durable task state

Suggested category: Coding agents

I am part of the team behind LongHorizon-Harness, so I wanted to disclose that connection.

If this fits the list, I can prepare a clean README-only contribution following the repository format.
