Connected Systems: Understanding Infrastructure Through Infrastructure
“An agent without roles becomes a loud intern that nobody can manage.”
Agents do not only change how work is done. They change who feels responsible for the work.

In the early days, a team often treats an agent like a shared gadget. People throw requests into a chat. The agent answers. Sometimes it even takes actions. Then something goes wrong and everyone asks the same question: who was supposed to be watching?
This is not a technical problem first. It is a workflow design problem.
The most reliable teams treat agent work like any other important work: they define roles, they define handoffs, and they define what counts as done.
A simple role model that holds up well is a three-part workflow:
• The requester defines the intent and success criteria.
• The reviewer verifies the evidence and checks safety.
• The operator executes the action or authorizes the commit.
One person can hold multiple roles in a small team, but the roles must still exist. Without roles, you end up with confusion and quiet risk.
The Requester Role: Clarify the Mission Before the Agent Moves
Requesters often think their job is to ask a question. In production workflows, their job is to define success.
A strong requester provides:
• The goal, not only the task
• The constraints that must not be violated
• The context that matters, including what has already been tried
• The definition of done, written in plain language
This prevents task drift. It also prevents a common failure where the agent produces something plausible but irrelevant.
Requesters should also answer one question explicitly: what is the acceptable risk?
If the task touches customers, production systems, payments, or security posture, the requester should expect approvals and slower lanes. That is not bureaucracy. That is stewardship.
Requester inputs that save hours later
These inputs are small, but they change outcomes:
• Known constraints: rate limits, maintenance windows, policy requirements
• Non-goals: things the agent must not do, even if they seem helpful
• Required evidence: logs, metrics, citations, screenshots, tool outputs
• Decision owner: who will say yes when tradeoffs appear
When requesters supply these up front, the agent does not have to guess what matters.
The Reviewer Role: Turn Agent Output Into Something Trustworthy
Reviewers are not there to nitpick style. They are there to verify the substance.
A reviewer’s job is to ask:
• What evidence supports this output?
• Are the citations real and relevant?
• Did the agent follow the tool contracts and guardrails?
• Are there contradictions or missing checks?
• Is there any data exposure or unsafe scope?
Review is not only about catching errors. It is also how teams learn what the agent is good at and what the agent should never do.
If you make review normal, your agent improves. If you make review rare, your incidents become your training data.
Review as a checklist, not a debate
A practical review checklist avoids long arguments:
• Evidence: cited excerpts or tool outputs are attached
• Scope: the agent stayed within the requested domain
• Safety: approvals were used when required
• Clarity: the output states assumptions and unknowns
• Next step: the operator has a clear action path
When these items are satisfied, reviewers can approve quickly and confidently.
The Operator Role: Make Execution Safe and Reversible
Operators are the people who carry the responsibility for side effects. They run the command, press the deploy button, merge the change, send the message, or authorize the commit token.
Operators should have tools that support safety:
• Previews and diffs before execution
• Idempotency keys and deduplication for retries
• Rollback options and reversal stories
• Run reports that document what happened
The operator’s mindset is different from the requester’s. Requesters want speed. Operators want control. Good workflows respect both.
Workflow Artifacts That Make Work Legible
The easiest way to enforce roles is to require artifacts that map to those roles. When the artifacts exist, the workflow becomes repeatable.
Artifacts that work well:
• Task request: goal, constraints, definition of done, risk level
• Agent plan: proposed steps, evidence to collect, tools to use, stop rules
• Review record: what was checked, what was approved, what is still risky
• Execution record: what actually ran, with timestamps and outcomes
• Run report: a single page that ties the whole run together
A strong run report is not busywork. It is the thing that makes agent work auditable.
When teams skip artifacts, they rely on memory. Memory becomes the enemy of safety.
Lanes: Fast, Standard, and High-Risk
Teams often think approvals slow everything down. In practice, approvals speed things up when they are applied selectively.
A lane model keeps the team moving:
• Fast lane: read-only tasks, drafting, summarization, low-risk proposals
• Standard lane: changes with clear diffs, reversible actions, known runbooks
• High-risk lane: customer-facing actions, production changes, security posture changes
Each lane has a different default:
• Fast lane defaults to automatic execution of read-only and drafting steps.
• Standard lane defaults to review, then operator commit.
• High-risk lane defaults to explicit human approval and heightened monitoring.
The agent should not decide the lane. The requester declares it, and the reviewer can upgrade it if needed.
Handoffs That Keep Teams Calm
Most agent failures feel stressful because the handoff is unclear. The agent outputs something, people skim it, then the system changes and nobody remembers what was approved.
A stable workflow makes handoffs explicit:
• The requester submits a task request with acceptance criteria.
• The agent produces a proposal, evidence, and a run report draft.
• The reviewer approves or requests changes.
• The operator executes with the approved plan and records the result.
• The run report is finalized and stored.
This flow creates a paper trail that protects everyone. It also creates a training set of approved patterns you can use to improve your agent policies.
When Work Goes Wrong, Roles Become Mercy
The value of roles becomes obvious in the moment of failure.
Imagine an agent proposes a configuration change. The output sounds clean. In a chat-only workflow, someone copies the command and runs it. Ten minutes later, a service degrades and the team scrambles to reconstruct what happened.
In a role-based workflow, the same moment is calmer:
• The requester can point to the goal and constraints.
• The reviewer can point to the evidence and the approval record.
• The operator can point to the execution record and rollback steps.
Roles do not prevent every mistake. They prevent the second mistake: panic without facts.
The Agent as a Team Member, Not a Replacement
Teams sometimes build workflows as if the agent will replace people. That is where conflict starts.
A healthier framing is that the agent is a team member with a specific shape:
• It can gather information fast.
• It can propose structured plans.
• It can draft artifacts and run reports.
• It can execute low-risk steps inside guardrails.
• It cannot own responsibility.
Responsibility stays with people. When that is clear, teams relax and adoption increases.
A table that makes roles practical
| Role | Primary responsibility | What it prevents | Common failure | A simple fix |
|---|---|---|---|---|
| Requester | Define goal, constraints, and done | Drift and misaligned output | Vague requests with hidden expectations | Require acceptance criteria and risk level |
| Reviewer | Verify evidence and safety | Confident wrong answers | Approving based on tone, not proof | Require citations, tool outputs, and explicit assumptions |
| Operator | Execute and record side effects | Untracked changes and irreversibility | Executing without a preview or rollback | Enforce preview, commit token, and run report completion |
This table is the reason the workflow works. It does not rely on everyone being unusually careful. It relies on the system making care normal.
The Verse Inside the Story of Systems
If you zoom out, agent workflows are a lesson in how teams handle power.
| Theme in team life | Expression in agent workflows |
|---|---|
| Speed is tempting | Guardrails and roles keep speed from becoming recklessness |
| Clarity reduces conflict | Acceptance criteria and run reports turn feelings into facts |
| Trust is earned by evidence | Review is an evidence practice, not a hierarchy practice |
| Responsibility must be located | Operators own side effects, not chat threads |
| Learning requires records | Approved run reports become the map for improvement |
When you build workflows this way, agents become a force multiplier for healthy teams. Without this, agents become a force multiplier for chaos.
