 ```
 
-Show reviewers the tool name, arguments, and enough context to judge drift from the user's original request — avoid rubber-stamp prompts.
-
-2. **Task-level human input** — set `human_input=True` when a task result must be reviewed before the crew continues:
-
-```python
-from crewai import Task
-
-review_task = Task(
-    description="Draft the outreach email for {topic} using the research notes.",
-    expected_output="A ready-to-send email draft for reviewer approval",
-    agent=sender,  # action agent from your crew
-    context=[research_task],
-    human_input=True,
-)
-```
-
-See [Human Input on Execution](/en/learn/human-input-on-execution).
-
-3. **Flow-level review** — use `@human_feedback` or Enterprise HITL webhooks for production review queues. See [Human-in-the-Loop](/en/learn/human-in-the-loop) and [Human Feedback in Flows](/en/learn/human-feedback-in-flows).

 <Tip>
-Default HITL helpers are often **blocking console** prompts. For production, wire a non-blocking provider or Enterprise webhooks so approvals land in Slack/Teams/your review queue instead of stdin.

-- Keep `allow_delegation=False` unless collaboration is required (this is the Agent default).
-- If you enable delegation, restrict which agents exist in the crew and which tools each one has. There is no separate "delegate only to agent X" ACL — membership and per-agent tools are the boundary.
-- Prefer explicit task graphs (sequential processes you design) over open-ended delegation for high-risk workflows.
-- In a **hierarchical** process, managers are set up to delegate. Keep high-risk tools on specialists behind hooks and approvals — not on every worker, and not on the manager unless required.
-- Treat remote/A2A delegation as a separate security domain. Prefer `A2AClientConfig`, leave `trust_remote_completion_status=False` unless you intentionally trust remote completion, and validate returned content before acting on it. See [A2A Agent Delegation](/en/learn/a2a-agent-delegation).
