kiln-coverage

What problem does it solve?

Verify that the codebase meets the 80% test coverage requirement from the constitution.

Core Features & Use Cases

• Automated coverage enforcement: checks line and branch coverage for changed files against an 80% threshold.
• On-demand tool provisioning: installs a coverage tool (e.g., @vitest/coverage-v8, c8, istanbul) if missing.
• Targeted evaluation: runs tests with coverage, parses reports, and reports per-file and overall results for the changed files only.
• Output-driven decisions: emits a pass when both line and branch coverage meet or exceed 80%, otherwise fails and lists uncovered files.
• Changed-file focus: uses git diff main...HEAD --name-only to identify touched files; handles cases with no tests gracefully.

Quick Start

Run the kiln-coverage workflow on the current branch to assess 80% coverage for changed files.
