This repository (PyUtility/polyskills) curates reusable
Agent Skills and agents under extensions/. This
AGENTS.md is the natively-discovered entry point for OpenAI Codex;
it is loaded automatically whenever Codex runs inside this repository. For Claude Code, the same content
is published as a plugin via .claude-plugin/marketplace.json.
The canonical skills live under extensions/skills/. Each is a standard
SKILL.md (with YAML frontmatter) and applies only when its description matches the task at hand.
| 🔖 Skill | 🎯 Applies When |
|---|---|
git-commiter |
Creating, amending, or writing any git commit message in this repository. |
markdown-format |
Creating, editing, or reviewing any *.md file (README, SKILL, AGENT, docs). |
python-code-format |
Creating, editing, or reviewing any *.py file or Python code. |
sql-code-format |
Creating, editing, or reviewing any *.sql file (PostgreSQL flavour). |
[!NOTE] The Python agent suite under
extensions/agents/python/targets Claude Code's subagent model, which Codex does not implement. Use the skills above with Codex; the agent behaviour can be invoked via thepolyskillsCLI adapter (prompt conversion) if needed.
Pick whichever path matches your Codex build:
-
Plugin marketplace (plugin-aware Codex). Register this repository as a marketplace and install the bundled plugin:
$ codex plugin marketplace add PyUtility/polyskills $ codex plugin add llm-essentials@polyskills
-
polyskillsCLI (any Codex build). Fetch individual skills into your Codex skills directory. The CLI is the project's single source of truth and supports private remotes and version pinning:$ pip install polyskills $ polyskills manager https://github.com/PyUtility/polyskills \ --source ./extensions/skills \ --name python-code-format \ --destination ~/.codex/skills/python-code-format \ skills -
Manual copy (native discovery). Copy any skill folder from
extensions/skills/into~/.codex/skills/(user-level) or.agents/skills/(project-level); Codex discoversSKILL.mdfiles there at startup.
