Pull request overview
Adds a new cli-anything-3mf harness (Click CLI + REPL) to inspect, modify, repair, and compare .3mf mesh files, and registers it in the project’s global docs/registry.
Changes:
- Introduces a full 3MF harness package (
cli_anything.threemf) with parser/inspector/modifier/repair core modules and trimesh-based geometry utilities. - Adds unit-test coverage for core functionality and publishes a skill file for agent discovery.
- Updates global registry and READMEs to include the new harness, plus
.gitignoreto track the new3MF/subtree.

python_requires is set to ">=3.9", but the PR description/registry entry/README for this harness state Python 3.10+. This mismatch can lead to users installing on 3.9 and then hitting runtime/type issues (e.g., X | Y annotations). Align python_requires (and classifiers if needed) with the documented minimum (likely ">=3.10").

inspect validates only mesh >= len(data.meshes); negative values (e.g., --mesh -1) will bypass the check and select the last mesh via Python negative indexing. Add an explicit mesh < 0 check (and ideally enforce 0 <= mesh < len(...)) so invalid indices fail with a clear error.

repair validates only mesh >= len(data.meshes); negative values (e.g., --mesh -1) will bypass the check and operate on the last mesh. Add an explicit mesh < 0 check (enforce 0 <= mesh < len(...)) to avoid surprising behavior.

repair_mesh (and the CLI/README text) claims normals are fixed, but the pipeline here only merges duplicates, removes degenerate faces, and removes unreferenced vertices. Either include a fix_normals step in repair_mesh (and report it), or adjust docstrings/CLI help so it doesn’t promise normal repair.

_perpendicular_axes uses dict indexing, so an invalid axis produces a KeyError rather than a clear ValueError. Even if axis is usually internal, validating and raising ValueError will make failures easier to diagnose (and matches the CLI docs that restrict axis to 0/1/2).

The test summary block now reports TOTAL 2,170 passed, but the earlier harness table total is ✅ 2,180+. Please reconcile these totals (and the per-harness counts) so there’s a single consistent source of truth.

The architecture tree lists tests/test_full_e2e.py, but the PR only adds tests/test_core.py (no test_full_e2e.py in this harness). Update the tree (and the unit/e2e test counts) or add the missing test file so the documentation matches the actual package layout.

It is well-structured and has substantial unit-test effort, but it has at least two merge-blocking correctness issues: the inspect/resize workflow is inconsistent, and the grouping algorithm conflates concentric features with different diameters.
- resize does not reuse the hole-detection parameters from inspect, so holes detectable only on a non-default axis cannot be resized at all. inspect exposes --axis/--planes/--min-confidence, but resize re-detects holes with default InspectParams(), which makes the workflow break for many real models.
- Circle grouping keys only on center and ignores radius, so concentric features with different diameters get collapsed into one averaged hole. That makes inspect report the wrong diameter and can cause resize to distort multiple sections of a stepped bore/counterbore together.
The 113 test cases passed when I ran them locally.

Thanks for the 3MF harness. Before merge, please preserve per-triangle attributes when rewriting meshes. The parser currently keeps only |
