NVIDIA Object Oriented Agents: the Pythonic way to build AI Agents.
This repository also configures its own agents. See what labs-OO-Agents tells them →

Solve an interactive grid game iteratively — observe, hypothesize, experiment, record knowledge, and submit action sequences until every level is won.
Skill Claude CodeCodex
Solve an interactive grid game by learning a compressed world model (encode state to a latent z, learn a predict function), planning action sequences by search over it, and recording hypotheses, plans and knowledge to memory.
Skill Claude CodeCodex
Create distinctive, production-grade frontend interfaces with high design quality. Use this skill when the user asks to build web components, pages, artifacts, posters, or applications (examples include websites, landing pages, dashboards, React components, HTML/CSS layouts, or when styling/beautifying any web UI).…

How to manage context blocks (system prompt sections) in NOOA. Use when configuring what appears in an agent's LLM prompt — adding, overriding, suppressing, or positioning blocks. Covers the unified Context API, well-known framework keys, and the declarative/runtime interface.
Skill Claude CodeCodex
Author agents with NVIDIA-labs Object Oriented Agents (NOOA). Use when writing or modifying an Agent subclass, agentic methods (ellipsis bodies), docstring prompts, structured output contracts, strategy selection (CodeAct/Predict), visibility control, orchestrators, or subagent composition.
Skill Claude CodeCodex
Make NOOA agent types render useful documentation for the LLM — doc(), spec(), hidden, Annotated field descriptions, and pformat/pprint tuning. Use when designing Pydantic models/dataclasses the LLM will see, controlling what appears in doc(self), hiding internals, adding field descriptions, fixing noisy or missing…
Skill Claude CodeCodex
Capture execution traces from NOOA. Use when instrumenting an agent run, writing traces to JSONL files, sending traces to the viewer or an OTLP/Langfuse/Phoenix backend, controlling which methods are traced, or when traces are mysteriously missing.
Skill Claude CodeCodex
Reactive input for NOOA agents — Channel/QueueManager for queued and event-mode input, race() turn dispatch, spawn() background jobs with JobHandle, and the bundled producers (monitor a shell command, cron ticks, one-shot timers, file tails). Use when an agent must react to external input mid-run — user messages, CI…
Skill Claude CodeCodex
Advanced tuning of NOOA strategies — CodeAct prefill, loop guards, text-only recovery callbacks, truncation, code restrictions, execution internals, and PredictStrategy tuning. Use when configuring CodeActConfig or PredictConfig beyond defaults, handling models that return prose instead of tool calls, writing a custom…
Skill Claude CodeCodex
Manage what a NOOA agent sees and remembers — context blocks, event history and queries, history summarization, and persistent memory/storage. Use when pinning information into the system prompt, querying past events, bounding context growth in long conversations, or persisting agent state.
Skill Claude CodeCodex
Intercept and observe NOOA execution — middleware via eventmanager.intercept() (guardrails, input/output transforms, blocking), event observers via eventmanager.on() (react to Task/Error/LLMResponse/turn events), and the InstrumentationHooks protocol for observability backends. Use when adding guardrails, redacting or…
Skill Claude CodeCodex
Let NOOA agents extend themselves — persistent skill libraries the agent writes and hot-reloads (SkillWriting / self.libs, LibraryManager), in-cell helper functions and standalone @strategy sub-calls (MethodWriting), and @slashcommand user actions. Use when an agent should accumulate reusable code across sessions…
Skill Claude CodeCodex
Give a NOOA agent capabilities — methods as tools, built-in tools (ShellTools, TodoManager), MCP servers, agent skills (Skill/TextSkill/SkillRegistry), and multimodal media. Use when adding tools or external integrations to an agent, wiring MCP, or packaging reusable guidance as an agent skill.
Skill Claude CodeCodex
Analyze NOOA execution traces programmatically with the trace-explorer CLI and Python API. Use when debugging why an agent run failed, inspecting LLM turns and code executions, diffing two runs, aggregating errors across an eval experiment, or root-causing behavior from a trace file or viewer session.
Skill Claude CodeCodex
Run and use the NOOA trace viewer — the web UI + OTLP receiver for browsing agent traces and eval results. Use when starting the viewer, importing/exporting/deleting traces, querying the viewer's REST API, or wiring an agent run so traces show up at localhost:5001.
Skill Claude CodeCodex
Render and refine the system prompt of a nooa agent. Use when the user wants to inspect, debug, or improve an agent's prompt, context blocks, or tool documentation.
Skill Claude CodeCodex
Explore and debug agent execution traces. Use when the user asks to analyze a trace, debug an agent run, investigate errors in a trace, or when they paste a trace-explorer prompt from the viewer UI.
Skill Claude CodeCodex
Configure and troubleshoot NOOA model registry entries with Connect or the library, including endpoints, credentials, reply budgets, reasoning levels, cache reuse and reasoning replay. Use for model onboarding, editing aliases, or Connect diagnostic handoffs, not Agent class authoring.
Skill Claude CodeCodex
Attach images, audio, video, and PDFs to NOOA agents. Use typed parameters or CodeAct show(), configure mediainputs, and troubleshoot text-only notices, URLs, MIME types, and size limits.
