/finops:caches

Analyze GitHub Actions cache usage - size breakdown, cache key patterns, branch distribution, and stale cache detection.

Context

Current repo URL: !git remote get-url origin

Parameters

Parameter

Description

Default

repo

Repository in owner/name format

Current repository

org:orgname

Analyze org-wide cache usage

Execution

bash "${SKILL_DIR}/scripts/cache-analysis.sh" $ARGS

Output Format

=== Cache Analysis: org/repo === Summary: 45 caches, 2340MB used 23% of 10GB limit === By Key Prefix === node-modules: 12 caches, 1200MB playwright: 8 caches, 800MB turbo: 15 caches, 300MB === By Branch === main: 10 caches, 500MB develop: 8 caches, 400MB PR 123: 3 caches, 150MB PR 118: 3 caches, 140MB === Largest Caches === node-modules-linux-abc123: 180MB playwright-linux-def456: 150MB === Stale Caches (>7 days old) === 8 stale caches, 450MB reclaimable Oldest: 2025-01-15T10:30:00Z === PR Branch Caches === 12 PR caches, 580MB (check if PRs are merged/closed)

Post-actions

Based on findings, suggest:

High % of limit -> Clean up stale caches, review key strategies

Many PR caches -> Add cache cleanup workflow for closed PRs

Large single caches -> Consider splitting or compressing

Stale caches -> Provide cleanup command:

# Delete stale caches
gh api "/repos/$REPO/actions/caches?per_page=100" \
  --jq '.actions_caches[] | select(.last_accessed_at < "CUTOFF") | .id' | \
  while read id; do gh api -X DELETE "/repos/$REPO/actions/caches/$id"; done
