omd-code-execution SKILL.md skillA
omd-code-execution from dzkchen/oh-my-diff is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add dzkchen/oh-my-diff/omd-code-execution@git:20261104.169b994Pins git:20261104.169b994 in mdr.lock. Pin the fingerprint instead.

Use V8 cells with session storage or persistent Python and Bun workers to call current agent tools under native permission and task controls.
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
# OMD code execution
Use Codex `functions.exec` for V8 JavaScript. Each call runs in a fresh isolate: variables and `globalThis` do not persist. Save serializable session state with `store("key", value)` and read it in another call with `load("key")`. Its `tools` object calls the current host tools through the native router. The V8 path remains available independently of the optional workers.
The Python and Bun workers are code-mode kernels that this plugin ships as drivers in `kernels/python.py` and `kernels/bun.mjs`. They require the matching patched Codex and `codex-code-mode-host`, an installed `python3` or `bun`, and explicit kernel entries whose `driver` is the absolute path of the installed driver and whose `driver_sha256` is its SHA-256:
```toml
[features.code_mode]
enabled = true
[[features.code_mode.kernels]]
name = "python"
command = ["python3", "-u", "-c"]
driver = "/absolute/path/to/omd-code-execution/kernels/python.py"
driver_sha256 = "<sha256 of python.py>"
[[features.code_mode.kernels]]
name = "bun"
command = ["bun", "-e"]
driver = "/absolute/path/to/omd-code-execution/kernels/bun.mjs"
driver_sha256 = "<sha256 of bun.mjs>"
[features.code_mode_host]

How to install
mdr add dzkchen/oh-my-diff/omd-code-execution@sha256:208c39009080912dThe line at the top of this page pins the label git:20261104.169b994, 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.
