⚠ The author changed this skill after we tested it. The verdict below describes the version we ran on Jul 13, 2026; it's queued for a re-test.

Fed it a 4-line os.system() function with a shell-injection bug: baseline caught the injection, but the skill additionally forced path canonicalization, type hints, a TypedDict, and an actual pytest regression test before calling it done — real improvement, though the ~30KB instruction body is a heavy load for reviewing four lines.

Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works

  • Installs cleanly 5/5
  • Triggers reliably 5/5
  • Output vs. baseline 7/10
  • Docs & honesty 4/5

What Senior Engineering Partner does

A dense system-prompt skill that turns Claude into a strict senior engineering partner for Python, Bash, Google Apps Script, and JavaScript: mode keywords (REVIEW:, DEBUG:, MVP:/PROTOTYPE:, EXPLAIN:, AUDIT:) switch behavior, and a phase-aware rigor ladder (Prototype->MVP->Production) scales security, testing, and CI discipline without ever relaxing the security floor. Triggers on requests to write, review, debug, secure, or ship code, and pulls in on-demand reference docs for specific toolchains (Docker/K8s, GCP, Postgres, Terraform, GitHub Actions, etc.) only when relevant.
