Curated by Skill Harbor — a Python design skill for writing maintainable code: fundamental principles over clever tricks — KISS, single responsibility, composition over inheritance, the rule of three (three instances before abstracting), dependency injection, and troubleshooting guidance for God classes, premature abstractions, tight coupling and entangled I/O. Ships quick-start examples (a dict beats a factory registry) with the detailed patterns in `references/details.md`. By @wshobson, listed here with credit to its creator. Honest caveats: Python-specific idioms — the mindset transfers, the snippets don't; the deep material is in the reference file, so the agent needs to open it. Skill Harbor never reviews the code, review it yourself before use.

Install
Prerequisites: a Python project to design or refactor Install "Python Design Patterns" for me. Maintainable Python: KISS, SRP, composition, rule of three, dependency injection Repository: https://github.com/wshobson/agents/blob/main/plugins/python-development/skills/python-design-patterns/SKILL.md 1. Fetch the SKILL.md file for the wshobson-python-design-patterns skill from the repository into a temporary folder and summarize what it does in one or two sentences. 2. Safety check: review the SKILL.md and scripts for anything suspicious (unexpected network calls, shell commands, credential harvesting). This repo should contain zero secrets in code, credentials only via the secure vault, allowed hosts declared in the SKILL.md. Verify that holds here; STOP on any red flag and tell me. 3. Install it as a skill: copy SKILL.md and its helper files into the agent's skills directory, in a folder named "wshobson-python-design-patterns". 4. Verify with no network calls: frontmatter valid, files in place. 5. Report what was installed, where, and what I still need to do myself (e.g. any accounts, API keys, or CLI tools mentioned in the prerequisites above). GitHub is optional: if I have a GitHub account or the gh CLI, you may use it; otherwise public access is fine. Never require it unless it's in the prerequisites above. Rules: don't touch anything outside the temp folder and the install target. Never ask me to paste secrets in chat — credentials go through the secure vault or environment variables. If anything looks off, stop and ask me.
Questions
How do I install a build?
Every product page includes a copy-paste install prompt. Paste it into your Muse and it sets the build up for you — no manual configuration.
Where does my money go?
Straight to the seller. Skill Harbor never processes payments: checkout happens on the seller’s own page, usually Stripe.
What does the ✓ next to a creator’s name mean?
It means we confirmed the identity of the person behind the listing. It says nothing about the code itself — always check a build before installing it.
