persistent-python SKILL.md skillA

persistent-python from answerdotai/aai-coding is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned

mdr add answerdotai/aai-coding/persistent-python@git:20261101.fe305fe

Pins git:20261101.fe305fe in mdr.lock. Pin the fingerprint instead.

The persistent clikernel Python session — Jeremy's preferred single tool for nearly ALL Python work. TRIGGER — read and bootstrap as step zero of EVERY session where clikernel is available, before the first tool call other than a Skill load: even tasks that only read a file or search a directory, plus stateful inspection, editing code or notebooks, debugging, experiments, API probes, data transforms, pyskills discovery, notebook-style work, local tool orchestration. If it could go through…

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

# Persistent Python

ALWAYS use the `clikernel` MCP server for ALL Python work: writing code, editing code or notebooks, running or debugging anything, inspecting objects or packages, probing APIs, and transforming data. It is the workbench for every task in this environment. If the work could go through Python, it goes through clikernel. Do not fall back to `python -c`, shell heredocs, or ad hoc scripts.

For Python, `py` (ipymini) is required. Start the kernel with `create(kernel="py")`. Never request `python3` (ipykernel) or another Python kernelspec. Check the clikernel MCP server instructions already in your context before the first call.

Run code with `exec(code=...)` in the selected persistent kernel. Imports, variables, monkeypatches, and cached objects carry across calls. `exec` never creates or switches kernels.

How to install

The exact contents, by fingerprint

mdr add answerdotai/aai-coding/persistent-python@sha256:2965d17d796d011f

The line at the top of this page pins the label git:20261101.fe305fe, 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.
