flag-state-coverage-builder

Overview

Building a flag-state coverage matrix from scratch is hard because the combinatorics explode. This skill walks through producing a realistic coverage matrix - not exhaustive, but sufficient.

The output: a coverage-matrix YAML + per-cell test skeletons + gaps documented for follow-up.

When to use

• New codebase adopting feature flags; no test coverage yet.
• A flag-related incident exposed a coverage gap; need to catch up.
• Adopting a new flag platform; existing tests need re-pointing.
• Periodic audit of flag-test coverage.
