/finops:compare

Compare GitHub Actions FinOps metrics across multiple repositories - cache usage, workflow frequency, failure rates, and efficiency.

When to Use

Scenario	Use this skill	Alternative
Compare CI metrics across org repos	/finops:compare	-
Identify worst-performing repos in org	/finops:compare	-
Org-wide cache or failure audit	/finops:compare	-
Deep-dive into a single repo's caches	/finops:caches	Use caches for single-repo detail
Deep-dive into a single repo's workflows	/finops:workflows	Use workflows for per-repo analysis
Quick summary of current repo only	/finops:overview	Use overview for single-repo snapshot

Parameters

Parameter	Description	Default
org	GitHub organization name (required)	-
repos...	Space-separated list of repo names	All org repos
--limit N	Limit auto-discovery to N repos	30

Usage Examples

# Compare specific repos
/finops:compare myorg repo1 repo2 repo3

# Compare all repos in org (up to 30)
/finops:compare myorg

# Compare more repos
/finops:compare myorg --limit 50

Post-actions

Based on comparison results:

• High cache repos: Run /finops:caches <repo> for detailed analysis
• High failure repos: Run /finops:workflows <repo> to investigate
• High activity repos: Run /finops:waste <repo> to find optimizations
• Create report: Consider creating a GitHub issue with findings
