Summary
CodeWhale merged an executable Gherkin acceptance-test harness covering command and tool lifecycle behavior. The change gives the DeepSeek TUI/CodeWhale project a behavioral testing layer before deeper command-system refactors continue.
What changed
CodeWhale PR #2887 merged a Gherkin acceptance E2E harness example tied to the command/tool lifecycle refactor track.
Why it matters
Agent tools often fail in interaction flows that unit tests miss. Acceptance-level specs help stabilize refactors across commands, approvals, and tool execution, which is increasingly important as open-source agent CLIs mature into production workflows.
Evidence excerpt
Agents Radar reported PR #2887 as merged, adding the first executable Gherkin spec for command/tool lifecycle while the staged command refactor continues.
