Summary

uv is available in pre-agent workflow steps, but not resolvable in AWF agent shell/tool execution.

Expected

If runtime setup (e.g., astral-sh/setup-uv) makes uv available on PATH before the agent step, uv should also be available inside AWF agent tool calls.

Actual

Inside AWF agent execution, uv resolves as command not found unless invoked via an absolute path.

Evidence

• Run: 23120336637
• Run: 23104424260

In run 23120336637:

• uv run ... -> bash: line 1: uv: command not found
• Absolute path invocation works in the same run.

Why this matters

This breaks runtime portability in AWF agent execution and forces workflow-specific absolute-path workarounds.
