The Software 3.0 Era: Raising the Floor of Organizational Productivity through Harness

Currently, many development teams are adopting LLMs, but due to differences in individual LLM Literacy, output quality varies drastically, leaving teams in a state of 'everyone for themselves.' To solve this, LLMs must be incorporated not as an individual's tool but as a team's system.

Claude Code's TUI environment and plugin ecosystem can serve as the key Harness for this. This is because it provides an experience where context is not interrupted within the developer's workflow, and can convert a team's knowledge into an executable SSOT (Single Source of Truth).

Deploying workflows through a marketplace has the following advantages over traditional RAG approaches:

• Predictability: Explicit code and logic allow 100% control over the context injected into the LLM.
• Rapid experimentation: Achieves Dev-Prod Parity, where plugins validated in a local TUI environment can be immediately applied even to server environments.

This is similar to platform engineering from the Software 1.0 era. Just as common libraries reduced repetitive work, AI workflow plugins will serve as Marketplace 1.0, deploying an organization's discipline and domain knowledge, and will raise the floor of team productivity.
