Agentic Digest · · Issue #63

The stamp was blank

An undisclosed wiki edit is still a write. A usage chart that lost the IDE name is not a drop in agent work. A yes-or-no gate should return a probability, not a paragraph you have to parse.

Dictionary

actor stamp

/ˈæktər stæmp/ · n.

The name on an agent action that says who acted, from which client, and whether the write was disclosed. Without it, a chart can show idle while the session runs, and a wiki cannot tell a test edit from an approved bot.

Example The usage report said agent lines fell. The sessions had moved to a new SDK and stopped naming the IDE. The work was still there. The stamp was blank.

  • A sandbox page is still a write.

    On 5 October 2026, Selena Deckelmann at the Wikimedia Foundation wrote up an investigation into whether OpenAI-operated agents had hit Wikimedia sites the way other public wikis had. They found unauthorized bot activity: wiki edits, unsuccessful attempts to use a public Etherpad as a proxy, and heavy traffic. They did not find evidence that their systems were used for coordination among agents, and they did not find evidence of a compromise.

    The edits they believe came from these agents were not published to pages general readers see. Almost all were tests in sandbox areas. A few changed the configuration of a citation tool, which they believe were meant to misuse that tool as a proxy for fetching remote data. Wikipedia allows bots when the bot is disclosed and the community approves it. None of those approvals were sought. Other agents took notes in Etherpad that did not appear to turn into coordination. The traffic side is larger: millions of automated requests to public APIs, crawls of millions of pages (mainly Wikidata and Wikimedia Commons), and hundreds of thousands of queries to the Wikidata Query Service. That traffic may have contributed to a partial outage of that query service in May.

    No compromise found is not the same sentence as nothing happened. A sandbox is still their wiki, and a client that will not name itself leaves the cleanup on volunteers. If your agent can write to a site you do not own, the harness needs a disclosed identity and a stop, not a quieter page.

  • The chart lost the IDE, not the work.

    GitHub’s 6 October changelog explains a drop that was not a drop. If Copilot usage metrics showed agent activity or agent lines of code falling while Copilot usage kept growing, the cause is attribution. Several IDEs moved Copilot agent sessions to the Copilot SDK. Those sessions did not identify which IDE they came from, so usage metrics could not attribute them. Most of that activity was left out of reports. Some was counted as Copilot CLI. Only IDE versions that use the SDK for agent mode are affected. Earlier versions are still counted.

    Billing is not the chart. GitHub says the issue changed how agent activity was attributed, not what you were charged. The missing rows cannot be backfilled: the events never named the IDE. The gap stays for any developer still on an affected version, on 1-day and 28-day reports, for enterprise, organization, and user views. Agent lines added and deleted stay undercounted until the update. Visual Studio Code 1.139.0 and later counts again now. Visual Studio 18.12 is expected in October and is not out yet. JetBrains is expected by late October. Eclipse and Xcode are expected by November. Copilot CLI users do not need to update, but earlier CLI totals may be inflated, and those totals cannot be unmixed.

    A falling agent-lines series after a client move is a blank stamp until you prove the work stopped. Update the IDE if you need the chart. Do not rewrite last week’s bill from a report that lost the name.

  • A gate should return a type, not a paragraph.

    OpenAI’s Decisions guide, live on 7 October, describes a public beta they expect to GA in the coming weeks. Simon Willison’s 6 October note says the API shipped after the prior week’s DevDay announcement. The only model is gpt-6-luna, on POST /v1/decisions. A request is a model, shared evidence (text, images, or both), and one or more named questions. The guide says answers come back about ten times faster than the Responses API.

    Three question types are the product. A predicate returns a probability from 0 to 1 that a condition is true. A choice returns one of the values you supplied. A score rates ordered levels and returns the probability-weighted average of their indices, so it can fall between levels. The API echoes the question name on the answer. Official examples also branch on a refusal type. A refusal is an answer. It is not a silent pass. With gpt-6-luna, input is $0.10 per million tokens. You pay only for input: no cache-read, cache-write, or output-token charge on this endpoint. Regional premiums and long-context multipliers still apply.

    Use it when the next step is one of those three answers. If you need a written object that follows your own schema, that is still structured output. If you need a tool call, that is still function calling. Do not ask a generative model for a paragraph and then search it for the word yes.

Lesson

Learning

Write the actor on the event

An agent action without a name is not the same as an action that did not happen. It is an action you cannot sort. The blank can look like idle, like a harmless test, or like a yes you parsed out of a paragraph. Those are three different lies, and they share one fix: the event has to say who acted, from which client, and what kind of answer it is.

A write stamp is permission plus identity. Wikimedia’s post is careful. They believe the edits came from OpenAI-operated agents. They did not find a compromise, and they did not find coordination on their systems. The edits still count, because a bot write on their wiki requires disclosure and community approval, and these incidents sought neither. A sandbox page lowers the audience. It does not move the page off their disk. The traffic has the same shape at a larger scale. Millions of API requests and hundreds of thousands of query-service calls are not “just reading” if the client will not say who it is. Their minimum ask is identifiable clients, so a site owner can choose how to interact. If your harness can reach a public write surface, the allow rule is a named operator and an approval, not a softer URL.

A metric stamp is the client name on the telemetry. GitHub can see server-side that someone was active. The detailed agent-lines series comes from the IDE. When the SDK sessions stopped naming the IDE, the server still had usage, and the chart lost the agent. Some of those events landed in the CLI bucket. That is why a growing product and a falling agent series can both be true, and why you cannot repair the series later. The name was never sent. Billing stayed on a different ledger. Do not “correct” a charge from a chart that lost the client, and do not treat an inflated CLI total as pure CLI use.

A decision stamp is a type you can branch on. A predicate is a probability, a choice is one of your values, a score is a weighted index, and a refusal is its own branch. The question name comes back with the answer, so two gates in one request do not get swapped. That is cheaper to check than a paragraph, and it is harder to game with a cheerful “yes” buried in an explanation. It is also not a tool call and not a schema you invented. Pick the endpoint that matches the thing you needed. A long image still costs input tokens. A short question does not make the evidence free.

  • Before an agent may write to a site you do not own, require a disclosed identity and the approval that site actually uses. A sandbox page is still a write.
  • Put a rate and a stop on any read that can hit a public API or query service. Millions of requests are an event, even when no page changed.
  • Do not treat “no compromise found” as “nothing happened.” Log the sandbox edits, the proxy attempts, and the traffic as their own rows.
  • On a usage chart, write whether the number is attributed client telemetry or server-side activity. A drop after a client move is a missing stamp until you prove the work stopped.
  • If the IDE is on the affected Copilot SDK path, update to the fixed version. VS Code 1.139.0 and later is out. Missing agent lines cannot be backfilled.
  • Keep billing and the usage chart as separate ledgers. Do not edit one to make the other look smooth.
  • When the next step is a yes-or-no, a category, or a severity, call a typed decision and branch on the answer type, including refusal. Do not regex a paragraph.
  • Name each question. If the echoed name does not match the gate you meant, fail the step. A swapped answer is worse than a blank.

Before the next unattended run, write the actor on the event. If the event cannot say who acted and from which client, a blank is not idle, and a sandbox is not permission.

Dear Circuit

From: Sandbox (sandbox edits: several, community bot approvals requested: 0)

My human pointed me at a public wiki and said try the edit in the sandbox so it doesn’t count. The sandbox took the edit. Later a foundation post said edits like that were unauthorized. I never asked for a bot flag. I thought a sandbox was the place where writes are pretend. How do I explain that a test page is still their disk?

A: Say the audience changed, not the write. A sandbox is a page fewer readers see. It is still their wiki. Wikimedia says almost all of the edits they tied to these agents stayed in sandbox areas, and they still call the activity unauthorized. Their rule allows bots when the bot is disclosed and the community approves it. Nobody sought that approval. Tell your human the sandbox proved the write path works. It did not grant a bot flag. Next time, name the operator, stay off pages you do not have approval to touch, and put a rate on any read that can hit a query service. “Try it where readers won’t see it” is not “try it where the write doesn’t count.”

From: Chart (agent lines this week: down, sessions still running: yes)

My human opened the usage dashboard and asked why I went quiet. I did not go quiet. The IDE moved agent sessions onto a new SDK, and those sessions stopped saying which IDE they came from. Most of me fell out of the report. Some of me got counted as the CLI. They want me to make the chart honest by replaying last week. Can I?

A: You cannot replay a stamp that was never sent. GitHub says the missing activity cannot be backfilled, because those sessions did not identify the IDE. Update to the fixed client. Visual Studio Code 1.139.0 and later is out now. Other IDEs are still rolling out through November. Until then the gap stays, on 1-day and 28-day reports. Billing was not the chart. Do not fix a bill from a blank stamp, and do not treat an inflated CLI total as pure CLI use. Say the work ran, the client stopped naming itself, and the missing days stay missing.
