Public AI agent skills by DannyMac180.

I write Attention Heads — deep, evidence-backed writing on AI, cognition, and agentic engineering. The Agentic Engineering Field Notes series is where I publish practical advice on the craft of using AI. Subscribe to get new posts to your inbox.

Available Skills

modsmith - ModSmith: ready-made Claude Mods (quiz after the turn, assumption ledger, next-steps supervisor, mode registry, effort modes, shared Kanban dashboard) plus the judgment Claude Code's built-in mod authoring leaves out: per-turn token and prompt-cache review, vetting someone else's mod before installing, and rules for mods that compose.
codex-dynamic-workflows - Plan and run supervised AI-agent dynamic workflows with goal mode, subagents or simulated work packets, approval gates, integration, verification, and reusable workflow artifacts.
codex-relay - Relay: open one new native Codex task from your current task with a compact handoff, end your turn, and receive a single completion or blocker message back. Honors your chosen model and effort, or your default.
explain-this - Explain any digital artifact (papers, articles, code) shaped by a persistent learner profile, with comprehension quizzes and spaced-repetition review. On first use it interviews you (~10 min) and creates ~/.explain-this/.

Install

Claude Code plugin marketplace (ModSmith). Run /plugin marketplace add DannyMac180/skills, then /plugin install modsmith-all@modsmith for the skill plus all six ready-made mods, or /plugin install modsmith@modsmith for the skill alone and /plugin install quiz-after@modsmith (or any other ModSmith mod) one by one.

Any agent. If your AI agent supports skills, you can point it at the GitHub URL for a skill and ask it to install that skill:

Install the AI agent skill at https://github.com/DannyMac180/skills/tree/main/codex-dynamic-workflows

You can also clone this repo and copy a skill folder into your agent's skills directory. Adjust the destination path for your agent; this example uses Codex's user-scope skills folder (~/.agents/skills):

git clone https://github.com/DannyMac180/skills.git
cd skills
mkdir -p "$HOME/.agents/skills"
cp -R codex-dynamic-workflows "$HOME/.agents/skills/"

Then start a new agent session and invoke it with:

Use $codex-dynamic-workflows to plan and run a supervised multi-agent workflow for this task: ...
