deep-fusion-over-plugin-install-for-skill-overlap-prevention

When integrating external skill repos that overlap with existing skills (e.g., impeccable’s anti-slop vs frontend-taste’s anti-slop), installing as-is creates skill ambiguity (violates Law #2) and context window bloat from two competing intelligence sources. The correct pattern is Deep Fusion: absorb non-overlapping intelligence into the existing skill, delete the redundant source. Plugin install is only appropriate for wholly new capability domains with zero overlap (e.g., WebGPU).
