GitHub Branch Protection Rules Are No Longer Enough

What GitHub branch protection can do

GitHub's branch protection rules cover the basics: required reviews, status checks, linear history, and force push prevention. These are good baseline controls—but they're binary: on or off. They don't understand context.

• Require N approvals before merge
• Require passing status checks
• Require signed commits
• Prevent force pushes

What they can't do

The most important delivery signals happen at the PR and deployment level, and GitHub branch protection rules miss them entirely:

• Can't detect self-approvals—GitHub doesn't check if an approver is the PR author
• Can't require linked issues—PRs with unclear scope merge anyway
• Can't cap PR size—a 1,000-line PR gets the same treatment as a 10-line fix
• Can't adapt based on developer role—protection rules are the same for everyone
• Can't track agent-authored code—GitHub has no concept of AI agent PRs

From binary rules to context-aware governance

Warestack adds context-aware enforcement on top of GitHub's baseline rules. Instead of binary on/off switches, you get declarative policies that understand who is shipping, what they're changing, and whether the output matches the intent.

What Warestack adds

Warestack ingests GitHub events in real time and enriches them with metadata that branch protection rules can't provide:

• Detect self-approvals and block them before merge
• Require linked Linear/Jira issues on every PR
• Cap PR size at configurable thresholds (e.g., 500 LOC)
• Adapt review requirements based on developer role and file paths
• Track agent-authored code and enforce stricter standards for AI-generated PRs
