Model routing for delegated work — use when spawning subagents or workflows, choosing a model for a task, or handing work to the Codex runtime. (Claude Code side; other agents rarely delegate.)
Fleet operations — use when a task involves other machines (discovering, reaching, or reasoning about them), installing/updating/removing any user-level tool, converging a machine, or working with paseo or the agent-fleet repo.
Prove what the Rerun viewer rendered — pixel evidence over logs. Use when a .rrd, blueprint, or Rerun rendering must be visually verified, when a timeline sweep or video of a recording is wanted, when an .rrd must be embedded in an HTML page, or when a gradio/WebViewer surface needs browser validation.
Python conventions for every repo — typing, dataclasses, return types, docstrings. Use whenever touching Python code.
Create self-contained single-file HTML artifacts when an explanation, plan, report, review, comparison, diagram, deck, prototype, or lightweight editor would be more readable, useful, or reusable in a browser than in markdown. Use for making dense information scannable and beautiful with semantic HTML, inline CSS, inline JavaScript, responsive layout, typography, charts, tables, annotations, tabs, collapsibles, timelines, diagrams, and copy/export affordances. Especially use when the user wants an artifact they are likely to open, read, share, or iterate on directly as a .html file.
Create a new single-purpose CV node in the monorepo with API layer (class-based node with verbose Rerun logging, result logging helper, config + result dataclasses), Gradio UI with embedded Rerun viewer (streaming binary stream), CLI entry point (tyro + RerunTyroConfig), and bundled example data. Use when adding a new model, predictor, or pipeline step as a standalone reusable app.
Performs conda-forge operations. Fixes failing builds by analyzing CI logs, creates new packages via staged-recipes, adds cross-compilation and ARM support to feedstocks, and migrates recipes from v0 to v1 format. Use when working with conda-forge feedstocks, staged-recipes, build failures, recipe migrations, or when the user mentions conda-forge.
