We revisit the minimal tension ($k=1$) string theory on$\text{AdS}_3\times\text{S}^3\times\mathbb{T}^4$. We propose a new free-fielddescription of the worldsheet theory and show how localization of stringamplitudes emerges from the path integral. We exemplify our proposal byreproducing the worldsheet partition function of the $\mathfrak{psu}(1,1|2)_1$WZW model and providing explicit expressions for spectrally-flowed vertexoperators and DDF operators. We compute string correlators in the path integralformalism and obtain a precise tree-level match with correlation functions ofthe boundary symmetric orbifold.
