Generate logos, icons, ornaments, illustrations, badges and diagrams with the image tool, then keep the chosen artwork as real SVG paths through SVG Studio. Use for an image-first visual-to-SVG request or /logo.
Handling rules for visual and document artifacts: PDFs, HTML reports, dashboards, slides and formula rendering. Load when creating, editing, verifying, or opening any of these artifact types.
Write, structure and compile LaTeX papers and reports (NeurIPS, ICML, ICLR, IEEE, ACM), including Persian and English XeLaTeX. Use for TeX manuscripts, LaTeX/XeLaTeX build errors, BibTeX checks or TikZ diagrams.
Drive a desktop Electron app (Elpis desktop, ChatGPT, Claude) as its user does, through its Chromium DevTools port: see, read, click, type. Use to try, test or compare app features first-hand. The Elpis TUI uses tmux instead.
Use only when the user explicitly asks for a first-principles review of a product, requirement, workflow, or implementation: question the requirements, delete what should not exist, then simplify.
Use for any bug, failing test, crash or unexpected behaviour, before proposing a fix. Root cause first, one hypothesis at a time, and a stop after three failed fixes.
Use for nontrivial implementation, requirements, a PRD or vision document, or acceptance criteria. Defines done before code. Not for trivial edits, exploration, spikes or prototypes.
Test-driven development: the agent writes the failing test, then the code, one behavior at a time. Use when building a feature or fixing a bug test-first, or when the user says tdd, red-green, or test-first.
