Excerpt

OpenSpec Plus TDD

Mission

Strict RED-GREEN-REFACTOR per test for OpenSpec change implementation. Every test — whether derived from a Gherkin scenario relevant to the slice in spec.md, written for a unit, edge case, helper, or error path — goes through its own atomic cycle before the next test begins. Production code exists only to make a previously-failing test pass. Surgical changes, simplicity first, no speculative abstractions, every changed line traces to a slice task.

This is the opening of the README. Read the full README on GitHub.
