The overall structure is thoughtful, but several of the new gates can currently crash, accept an unsafe plan, or report success without verifying the requested installation identity. I am requesting changes because these cases undermine the PR's central deterministic/validated-install contract. I reproduced the ldd false-positive behavior locally: an executable with a missing shared library still produced libmissing.so => not found while ldd exited 0.

The new skill has a solid gate-oriented structure, but I found four blocking correctness/security gaps in the contract: the documented proxy fallback does not authenticate the installed skill content; embedded placeholders can pass plan validation; LAMMPS paths are not cross-checked against C/C++ build/install paths; and the documented C/C++ ldd gate can pass unresolved dependencies. I also left two compatibility findings for Kokkos NCCL discovery and JAX CUDA/ROCm verification. Please add regression coverage for each boundary before merging.

I found four merge-blocking correctness/security issues and one ROCm completeness gap. In the current form, the skill can (1) install executable instructions through an unverified third-party supply-chain path, (2) validate plan values that can escape the rendered shell commands, (3) accept local paths for fields whose documented consumers require URLs, and (4) report the requested CUDA/ROCm runtime as verified when only an arbitrary GPU was found. Details and suggested fixes are inline.

Four additional correctness/security gaps appeared while tracing the validated plan through the actual command templates and easy-install verification paths. These are independent of the first review and should be covered by regression tests as part of the requested changes.

Re-review of current head 90e4625 against the repository's existing installation documentation found two remaining consistency issues.
-
[P1] The JAX C/C++ plan schema rejects an officially documented configuration.
source-cpp.mdexplicitly supports “JAX with TensorFlow C++” via-DENABLE_TENSORFLOW=ON -DUSE_TF_PYTHON_LIBS=ON, which uses the selected Python environment and does not require eithercpp.tensorflow_rootorcpp.tensorflow_c_root. However,plan-schema.mdstill states that every JAX C++ backend must provide one of those roots, and the validator follows that contract. This makes a documented JAX C++ route impossible to express as a valid plan. Please model the TensorFlow-Python-libs route separately (or only require a root for the TensorFlow C-library route) and add a regression case for JAX C++ usingUSE_TF_PYTHON_LIBS=ON. -
[P2]
package.channelsis recorded but ignored by the conda renderer. The schema stores an arbitrary channel list, buteasy-install.mdalways renders-c conda-forge. A plan using a selected mirror or the documented pre-release channels such asconda-forge/label/deepmd-kit_dev/deepmd-kit_rcwill silently install from a different channel than recorded. Render the conda command frompackage.channels(with an explicit stable default when the list is empty), or remove the field if it is not intended to control installation.

Summary
deepmd-installAgent Skill with progressive references for easy, source Python, C/C++, and LAMMPS installationsinstall-plan.jsoncontract plus deterministic environment, Python-backend, LAMMPS, and source-preparation helpersdeepmd/kkfrom DPA4Cdpa4spin/kk, including artifact and Kokkos architecture requirementsWhy
DeePMD-kit installation spans package managers, four Python backends, optional compiled interfaces, and multiple LAMMPS runtime layouts. Free-form agent instructions can lose shell state, select the wrong interpreter or accelerator, and pass superficial checks while the requested runtime is unavailable. This skill records decisions in a typed plan, runs self-contained gates, and verifies the requested public interface.
User impact
Users can install the skill directly from the repository, ask an agent for an easy or source installation, and receive a reproducible plan and gate-by-gate report. TensorFlow, JAX, and Paddle retain concise documentation-backed paths, while PyTorch graph deployments receive exact C++/LAMMPS/Kokkos verification.
