Every coding agent form factor shift is chasing the same thing: execution data

Coding Agent 的形态变化，都在抢同一样东西

DeepSeek is hiring an Agent Harness PM, signaling it's filling the gap of not having its own coding tool runtime. The article argues that desktop apps, managed cloud agents, and remote control are all moves to capture execution data. Interfaces converge because they're cheap to copy; execution layers diverge because that's where the data moat is. Without a first-party harness, DeepSeek lacks real-world coding feedback to improve its models. Judge a coding agent by who controls the execution environment, who sees the data, and who's in the data flywheel—not by feature checklists.

Why it matters: A sharp industry analysis that uses DeepSeek's hiring move and LangChain test data to argue 'harness = data moat.' Hits all three HKR axes, but as an opinion piece rather than a primary release, scored at the lower end of the 78-84 band per policy.
