agents

Writing standard: ASD-STE100.

This folder is the index of the Claude agents that the projects of h0ffmann use, or plan to use. An agent is a model that acts alone between a trigger and a result. It reads, decides and writes a report, a comment, a commit or an answer. The skills have a different index, in README.md.

The plugin does not install these agents. Each agent stays in the repository that runs it. To use one, copy its file into .claude/agents/ of your project.

Claude Code subagents

The eight files in this folder are copies, as is, of the subagents in the projects. Each file keeps the MIT licence of its source repository. Each agent only reads and reports. A person or the calling session makes the fix.

Headless agents of piabrota

These agents watch piabrota/nix-os and its VPS. Each one is a bash script that runs Claude Code headless, with read-only tools. They run on the VPS as rax tasks and post as the GitHub App piabrota-ops. The prompts are in piabrota/agents.

AgentWhat it will doState
tcc-ufrj-writerWrites a UFRJ undergraduate thesis (TCC) from end to end. Each chapter is Markdown first. Desmos and Archify make the figures. The build makes the LaTeX project and the PDFPlanned, in issue #3
Post writerWrites a draft news post in pt-BR and English for the two news reviewersIdea, in marola-agents
Site UI agentsDesign review, worst-case data, motion review and screenshots on marola.devIdea, in marola-agents

The runtime

h0ffmann/rax is the Rustic Agentic Runtime: a port of Google AX to pure Rust. It runs agentic tasks on Agent Substrate. The agents of piabrota run on it, from the piabrota/rax fork.
