/finops:compare
Compare GitHub Actions FinOps metrics across multiple repositories - cache usage, workflow frequency, failure rates, and efficiency.
When to Use This Skill
| Use this skill when... | Use a sibling instead when... |
|---|---|
| You need to benchmark CI metrics across many repos in an org | You only need a snapshot of the current repo — use /finops:overview |
| You want to identify the worst-performing repos in an org | You need a deep dive on one repo's caches — use /finops:caches |
| You are running an org-wide cache or failure audit | You need per-workflow analysis on one repo — use /finops:workflows |
| You want to rank repos by efficiency or cache size | You want actionable workflow waste fixes — use /finops:waste |
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
Execution

Agentic Optimizations
| Context | Command |
|---|---|
| List org repos (JSON) | gh api "/orgs/{org}/repos?per_page=100&sort=pushed" --jq '.[].full_name' |
| Cache count per repo | gh api "/repos/{owner}/{repo}/actions/caches" --jq '.total_count' |
| Workflow runs (JSON) | gh api "/repos/{owner}/{repo}/actions/runs?per_page=100" --jq '.workflow_runs' |
| Compact multi-repo compare | bash "${SKILL_DIR}/scripts/compare-repos.sh" $ARGS |
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
