td-python-extension SKILL.md skillA
td-python-extension from touchdesigner/tdmcpskills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add touchdesigner/tdmcpskills/td-python-extension@git:20260616.c15db43Pins git:20260616.c15db43 in mdr.lock. Pin the fingerprint instead.

Python extensions — extension classes, ext0object, parameter callbacks, lifecycle, state/persistence, scriptTOP/numpy. Use when building Python-driven baseCOMPs.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Python Extensions
Patterns for Python extension components in TouchDesigner. Complements `td-comp-architecture` (structure/custom pars) and `td-dat-family` (callback mechanics). See `reference.md` for API signatures and `examples.md` for complete patterns.
## Create an extension — one pass
The fixed choreography. Author the class (step 3) and verify (step 7); the rest is invariant.
Mirrors what TD's own Component Editor produces.
1. **`baseCOMP base_<x>`** — name it now; binding and docked refs snapshot at creation.
2. **`textDAT <Name>`** inside — DAT = module = class, one identifier (e.g. `SimpleExt`).
3. **`set_dat_content`** the Skeleton (below) → `code/py/<comp-path>/<Name>.py`.
4. **`language=python`** — set it explicitly; `set_dat_content` doesn't (see Sync to File).
5. **`ext0object = op('./<Name>').module.<Name>(me)` + `ext0promote=True`** — leave `ext0name`
empty (promoted under the class name). `ext0` always exists → no sequence management.
6. **pulse `reinitextensions`.**
7. **Gate — not done until proven:** `get_errors` clean AND a promoted member called from outside
returns a value (`op('base_<x>').Hello()`). Print it.

How to install
mdr add touchdesigner/tdmcpskills/td-python-extension@sha256:c0fce6255aa9b907The line at the top of this page pins the label git:20260616.c15db43, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
