Verdict: Tested · Works
Score: 9.2/10
Tested: Jul 16, 2026
Environment: Claude Code 2.x (agent harness)
Upstream re-checked: Aug 10, 2026 · f677ac3

Tried to actually follow the skill's mandated 'verify with official sources, never rely on memory' rule for the 2024 employee lump-sum figure: the specific BMF page died (404), a secondary source confirmed EUR1,230 -- concretely showing why the skill's no-memory-reliance rule exists (official pages move) and that it's a real, non-trivial obligation, not boilerplate.
