Auto-generated from the upstream codegen home.

Version: 1.2.1 (patch; every sync bumps +0.0.1)
Upstream: agent_platform@e0ae20c

Note

Low Risk
Additive optional query parameter and patch version bump in generated SDK code; no auth or breaking API changes.

Overview
Syncs the hai-agents Python SDK to v1.2.1 (OpenAPI, pyproject.toml, lockfile, and client User-Agent headers).

list_agents gains an optional reserved query parameter on sync and async clients: true returns only reserved h/ agents, false only org agents. When omitted, behavior stays the same as before (reserved plus the caller’s org agents, per existing docs).
