Summary

  • design-iac (new): Infrastructure as Code design skill grounded in Kief Morris "Infrastructure as Code" (O'Reilly 2021) and NTNU IIKG3005 — immutable infra principles, snowflake anti-pattern, module design, remote state management (S3/GCS/Azure), drift detection & remediation, GitOps workflow, IaC testing with Terratest/checkov (3 reference files)
  • tool-perf (new): Performance engineering grounded in MIT 6.172 (Bentley Rules, Leiserson/Shun) and Brendan Gregg "Systems Performance" — USE Method resource checklist, profiling tool selection by stack (perf/py-spy/pprof/async-profiler), flamegraph reading guide, all 5 Bentley Rule categories, before/after benchmark workflow → perf-findings.md output (3 reference files)
  • design-migration (deepened): Added Kleppmann DDIA Kap. 4+11 coverage — Forward/Backward Compatibility rules, Dual-Write problem & solutions (CDC, Outbox Pattern, Event Log), CDC/Debezium zero-downtime migration flow, Avro Schema Registry, Expand-Contract decision tree; new references/schema-evolution.md

Housekeeping

Test plan

  • Pre-commit hooks pass (markdownlint + validate-skills.sh) ✅ verified locally
  • /dev:design-iac slash command discoverable after install
  • /dev:tool-perf slash command discoverable after install
  • meta-help menu shows 24 items with correct numbering
  • design-migration triggers include CDC/Dual-Write/Schema Registry keywords
