Shows a Strands orchestrator delegating to a sub-agent through the agents-as-tools pattern, with per-agent authority enforced in-process by attenu-guard (Apache-2.0). The sub-agent's permissions are computed as the meet of its request and its parent's authority, so a hand-off can only ever narrow; an out-of-authority tool call is cancelled before the tool body runs, and the run's decisions are recorded in a hash-chained, offline-verifiable audit log. Runs fully offline against a scripted model (no AWS account, no model access) with a matching pytest suite; the AgentCore deploy commands are documented but not executed. Sample author maintains attenu-guard.

Strands'
BeforeToolCallEventhook (no monkeypatching)Enforcement comes from
attenu-guard(Apache-2.0, not part of the AWS SDKs).How to run:
uv venv && uv pip install -r requirements-dev.txt, thenpython local_run.py(offline, scripted model, no AWS account) andpython -m pytest. The AgentCore deploy commands (agentcore configure/launch/invoke) are documented in the README but not executed as partof this PR.
What the reader sees: the sub-agent reads logs (permitted), then tries to
export findings to an external destination (not permitted) — the call is
denied before the tool body runs, and the offline run prints the denial plus
a verified evidence bundle.
Refs #2013 (opened first per CONTRIBUTING).
