2. v0.0.9 Aug 18, 2026 · release notes

   OO-Agents v0.0.9 adds plugin-based CLI extension, a portable journal exporter, callable LLMLLMA large language model, a neural network trained on large amounts of text to recognize patterns and generate language. Applications use it for tasks such as answering, summarizing and writing code. routing in @strategy, shared interactive sessions, and a CyberGym portfolio agent.

   • Enables external packages to add nooa subcommands via Python entry points, allowing third-party plugins to extend the CLI without forking.
   • Adds a portable journal file exporter for tracing, giving teams an offline-portable trace format independent of a remote viewer.
   • Allows a callable to be passed to @strategy(llm=...), enabling dynamic LLM selection per strategy invocation instead of a static reference.
   • Adds LLM routing metadata to generation observability, surfacing which backend was selected in trace output.
   • Adds a shared interactive session foundation, enabling multiple agents to collaborate within a single interactive context.

   • Constrains playground custom-model endpoint and api_key_env to server-declared pairs, preventing clients from supplying arbitrary LLMLLMA large language model, a neural network trained on large amounts of text to recognize patterns and generate language. Applications use it for tasks such as answering, summarizing and writing code. endpoints.
   • Adds resource limits on the viewer ingest path to cap memory and request size for the trace-viewer API.
   • Requires an auth token and restricts CORSCORSA browser mechanism that lets a server declare which foreign origins may read its HTTP responses, enforced by the browser to block unauthorized cross-site requests from JavaScript. on the viewer API, narrowing the attack surfaceattack surfaceThe exposed systems, interfaces and access points an attacker could try to use. It includes internet-facing services as well as identities, software and other reachable resources. of the local trace viewer.
   • Confines ShellTools file operations within the current working directory, limiting the filesystem surface available to agent-executed shell commands.
   • Adds a NOOA cybergym agent example (examples/) demonstrating a cybersecurity-oriented agent built on the OO Agents framework.

   • Replaces eval() in the CodeAct constructor-string coercion path with an ASTASTAn abstract syntax tree, a structured representation of parsed code. Tools inspect or transform this tree to understand expressions and statements rather than just matching text. decoder, removing arbitrary code execution from that code path.
   • Publishes the package to PyPI via Trusted Publishing on GitHub Releases, enabling pip install nooa / uv add nooa installs from official releases.
