"""This sample demonstrates manual static wiring of CodeAct without a provider.

Instead of using `HyperlightCodeActProvider` with `context_providers=`, this
sample creates a `HyperlightExecuteCodeTool` directly, extracts its CodeAct
instructions once, and passes both to the `Agent` constructor at build time.

This avoids the per-run provider lifecycle (`before_run` / `after_run`) and is
well-suited when the tool registry, file mounts, and network allow-list are
fixed for the agent's lifetime. The tradeoff is that dynamic tool or capability
changes between runs are not supported — any mutations to the tool would not
update the agent's instructions automatically.
