Diff Analysis

Analyze git diffs for risk, complexity, and reviewer assignment.

When to use

Before submitting a PR or after making significant changes, analyze the diff to understand risk level, get reviewer recommendations, and classify the type of change.

Steps

0. Pick the ref — HEAD for uncommitted work, main..BRANCH for a branch (--branch), or the PR's base..head range (--pr, resolve it with gh pr view N --json baseRefName,headRefName). The analyze_* tools take a ref and run git themselves; they do not accept diff text.
1. Analyze diff — call mcp__plugin_ruflo-core_ruflo__analyze_diff with { ref, includeFileRisks: true } for a comprehensive analysis
2. Risk score — call mcp__plugin_ruflo-core_ruflo__analyze_diff-risk with { ref } for a quantified risk assessment
3. Classify changes — call mcp__plugin_ruflo-core_ruflo__analyze_diff-classify with { ref } to categorize (feature, bugfix, refactor, etc.)
4. Get reviewer roles — call mcp__plugin_ruflo-core_ruflo__analyze_diff-reviewers with { ref, limit } for roles inferred from paths and risk; check CODEOWNERS separately when assigning people
5. Diff stats — call mcp__plugin_ruflo-core_ruflo__analyze_diff-stats with { ref } for line counts, file counts, complexity metrics
6. File-level risk — call mcp__plugin_ruflo-core_ruflo__analyze_file-risk with { path } (required) for each file the earlier steps flagged

Risk factors

• Files with high churn history
• Security-sensitive paths (auth, crypto, permissions)
• Large diffs (>500 lines)
• Cross-module changes
• Database migration files
