What separates an autonomous agent demo from a run?
Microsoft calls autonomous AI agents "systems that can independently analyze situations, make decisions, and act". Its Copilot 101 page adds that they "don't just follow preset instructions" (Microsoft). Salesforce says autonomous agents "can execute on tasks and workflows independently" (Salesforce). Both sentences are true. Neither lets you picture what an agent does at 02:40 on a Wednesday with nobody awake.
The useful question is what you would actually let run. An example earns its place when it shows three things: what fired the run, what the run could touch, and what a person found waiting at the end. Follow one case the whole way and you can check those three against your own work.
A pull request is enough to start a session
Take the review case, where nobody asks for anything. A pull request opens in a connected app, and the event trigger attached to it fires. The trigger types are "cron (a schedule slot arrives, or once at run_at), webhook (a signed POST reaches the trigger's URL), event (something happens in a connected app, such as a new pull request or a new email) and monitor (a command from your repository prints a line on stdout)." An event fire substitutes the payload's values into the prompt. The session opens already holding the pull request and its branch.
Nobody picked this up from a queue, and nobody pressed go.
The session gets a branch and a short list of tools
"A session runs one agent in its own sandbox. The sandbox clones the repo and works on a new branch." The branch carries the session id. Everything this run changes sits on that one ref, and the default branch stays as it was.
The tools are policy, written before the run. "Rule each tool call allow, ask or block." The rule can reach the arguments a call was given. That is how a review agent gets a read on the repository, the test command and a comment on the diff, and nothing near a merge. Write the list before the first Tuesday night. At 03:00 those rules stand in for the person who would otherwise have said no.
What lands is a change request
"The agent commits, pushes the session branch, and opens a change request against the project's default branch. A person with the project.gitops.merge permission reviews the change request and merges it."
The reviewer on the other end does not read a chat summary. They read a diff, the comment on the changed line, and the test that failed. Nothing the run produced is live until that merge. A rejection costs a minute, and the default branch loses nothing, because the work never left its branch.
The permission answers the question these examples raise. An agent can open the change; a person still owns the merge.
The other three cases, read the same way
Each of the four cards follows the same steps. Only the fire changes.
- The digest starts on a schedule slot. A cron trigger takes a six-field expression, second first, and fires at most once a minute. The manifest is a handful of lines. The output is one page of state a person skims with coffee.
- The intake starts on a signed POST. "Every webhook trigger needs a signing secret. There is no unsigned webhook." The signature is the HMAC-SHA256 of the raw request body, keyed with that secret. A stranger who finds the URL gets a 401 instead of a CRM record. The CRM connector signs in with a credential Kortix brokers: "Connector credentials are brokered server-side and never enter the machine."
- The monitor starts when a command from the repository prints a line. A threshold crossing that used to wait for a dashboard refresh opens a session. The session opens a change request with the fix in it.
The made-up parts
The artifacts in the four cards are invented. Acme, Globex and the counts in them describe a shape, and the repositories do not exist. Everything around them is real behaviour, linked where it appears: the trigger types, the sandbox and its branch, the change request and the merge permission, the tool policy.
Three pages go further. Running an agent with nobody watching writes a trigger from an empty project and caps how often it fires. Autonomous vs human in the loop covers the three places a person can stand in a run like these. What autonomous AI agents are takes the vendor definitions apart.
