Instructions

Describe this figure so a reader who cannot see it understands both what it depicts and what it communicates. The description should be detailed enough that someone could reproduce or redraw the figure from the text alone.

Claude Code Configuration

Security hooks

All hooks live in hooks/ and are symlinked into ~/.claude/hooks/ by Home Manager. They run as Claude Code lifecycle events and exit with one of three codes:

Exit code	Meaning
`0`	Allow (or ask-mode: present a permission dialog)

Customize TimeMachine Exclusions

Add exclusions by dirname

find $(pwd) -type d -name <NAME> -maxdepth 3 -exec tmutil addexclusion {} \;

Automate exclusions

Cleanup legacy GitHub Actions workflow runs

Python utility to delete GitHub Actions runs for a repository, based on parameters. The GitHub UI currently allows removal of individual workflow runs, but this becomes tedious with a bulk of previous runs. Credit: https://gist.github.com/magnetikonline/2242eb18bf8890e9fc72b3c3ef41bd93

Usage

Create a Personal access token allowing the workflow scope:
Execute the script against a target GitHub repository (with optional parameters).

Creating / Managing conda envs

Rules / SOPs:

Don't work in base environment
Use mamba as a solver
Create default environments with pinned packages, and clone / update the default envs as needed

Creating / Managing conda envs
- Create a new env

	#!/bin/bash

	## assumes "multiple repos" are all in the same parent directory, which is also the current working directory

	# set up git
	for dir in ./*/; do
	dir=${dir%*/} # remove the trailing "/"
	cd "$dir"
	echo "$dir"
	git fetch -p && git pull
