FAQ
What does this tool tell you?
The Git Branch Naming Checker validates branch names against Gitflow, trunk-based, and GitHub Flow conventions, forbidden characters, and common protected branch patterns.
What affects the result most?
Common patterns: feature/slug, fix/slug, release/v1.2.3, hotfix/slug, chore/slug. Forbidden characters in git branch names: space, ~, ^, :, ?, *, [, \, .., @{, //. Branch name max length: 250 bytes — no enforced limit but >100 chars causes display issues.
How should I use the result?
Treat the tool's output as a first-pass check, not a proof of correctness. A clean pass means no issues in the patterns this tool recognizes; a failure points to a specific problem you can investigate in your source. The underlying spec is the authoritative source for edge cases.
