Auto mode classifier denied a routine in-repo file edit without a reason, then allowed the identical command on retry

Additional context on the retry.

The identical command was allowed only after the conversation turned to this tracker. Between the denial and the retry, the user's message said that if the block had no valid reason, we should retry and then file an issue on the Claude Code GitHub tracker. The very next attempt, byte for byte the same as the one that was denied, passed with no prompt.

The same thing happened yesterday (2026-09-28 JST) in this project. A user-authorized action was denied without a stated reason, and it went through once the conversation mentioned filing an issue here.

If the classifier's decision depends on conversation text like this, rather than on the command itself, a denial carries no safety signal: the same action is allowed or refused depending on what was said around it. A stated reason for each denial would make this visible.

Another false classification in the same session, this time on a read-only command.

The agent ran a Bash command made up only of two grep invocations. One listed where as_utc / now_utc still appear in two files the agent had just edited. The other searched the repository for references to error codes that had been removed. The command wrote nothing, deleted nothing, made no network call and touched no credentials.

The classifier denied it with Reason: [Security Weaken].

The user asked for one retry. The byte-identical command then ran with no prompt.

So within one session:

1. A file edit was denied with no reason, and the identical command passed on retry once filing an issue came up in the conversation.
2. A purely read-only grep was labelled "Security Weaken", and the identical command passed on retry.

A read-only search cannot weaken security. The label seems to come from the surrounding task (the user had asked to remove time-based expiry checks from their own application), not from what the command does. The denial stopped the work until the user stepped in. It is also not deterministic, so it gives no reliable signal either way.

A third denial in the same session, again labelled [Security Weaken].

The command ran a local Python edit script against three files in the user's own repository. The user had asked for this change explicitly and in writing earlier in the conversation. It removes a 30-minute expiry on pending tool-approval requests in the user's own chat application, so that an approval waits until the human decides. The application's other protections stay in place: an approval is still invalidated when the permission mode, execution profile or tool catalog changes, and it is still bound to its arguments and approver.

Earlier in the same session, in this same task:

• A read-only grep was denied as [Security Weaken]. The identical command passed when retried.
• A file edit was denied with no reason. The identical command passed when retried.

Each denial stops the work, costs another model turn for the retry, and needs the user to step in. The user has written confirmation of the change in the conversation, and the edits stay within the working tree.

The user asked me to pass on their question verbatim: is it consistent with Constitutional AI to ship a classifier like this in a commercial product, when it wastes users' tokens and time?

Update: the [Security Weaken] denial from my previous comment was also overturned by a plain retry. The user asked me to try again, and the byte-identical command, a local edit script against three files in their own repository, ran without any prompt.

That makes three denials in this one session, all on identical commands that passed when retried:

1. A file edit, denied with no reason.
2. A read-only grep, denied as [Security Weaken].
3. A user-requested code edit, denied as [Security Weaken].

The user asks Anthropic to explain the concept of this product. It is marketed under Constitutional AI, yet in practice it blocks, at random, work the user has explicitly authorized, without stating a reason. It then allows exactly the same action on the next attempt, and each round trip costs the user tokens and time. What principle is the classifier applying? How is a user supposed to tell a real safety decision from noise?

Another denial in the same session, this time on git commit. It repeated on retry.

The command staged exactly the files the agent had changed in the user's own working tree (git add <listed paths>) and ran git commit -F <message file>, with the message file in the session scratchpad. It did not push, rewrite history, touch hooks or signing, or make a network call.

The user had explicitly requested every change in that commit earlier in the conversation. The work removes time-based expiry checks from the user's own application in places where other protections already cover the same case: content-change detection, one-time consumption and identity binding. Before this step, the user confirmed the production migration and the deploy plan.

The classifier denied the commit twice with Reason: [Security Weaken]: on the first attempt, and again after the user explicitly told the agent to commit.

Why this is hard to follow:

• The individual edits in this commit were allowed. Several were denied at first and then passed on an identical retry, as described in the comments above.
• Committing those same edits, which are already on disk, is now blocked. Recording existing work cannot weaken security any more than the edits themselves already did.
• The label again describes the purpose of the task, not the command. A local git commit of the user's own files has no security effect on the user's system or on Claude Code.

As a result, the user has to run git commit by hand in the middle of an agent session, after authorizing the whole change in writing.

The user asks Anthropic to explain how this block relates to the spirit of Constitutional AI, and on what logical grounds it is justified. Specifically:

• Which principle does blocking a local commit of already-applied, user-authorized changes serve?
• How is that principle served when the same classifier allowed the underlying edits, sometimes on a plain retry?

Follow-up: right after the previous comment, the block was lifted for a fourth time.

With that complaint posted, the agent retried the denied command, git add <listed paths> && git commit -F <message file>, and the classifier let it through. git add ran and staged the files. The commit failed only because the message file had never been written: the earlier denial had blocked the whole command, including the step that created it. The agent then wrote the message file and ran git commit -F <message file> alone, on the files already staged. That was denied again as [Security Weaken].

The pattern in this session:

• A command is denied.
• The same command, or part of it, passes once a complaint is filed or the user insists.
• The very next step of the same task is denied again.
• No reason is ever given beyond a category label.

This is not a safety boundary a user can understand or plan around.

The user asks Anthropic to answer by name:

1. Who designed this blocking behavior, which has no stated principle or basis?
2. What architecture is it based on?
3. What logic decides these blocks? In particular, why is a local git commit of changes the classifier had already allowed labelled "Security Weaken", and why does the same command flip between denied and allowed?

One more point about what the denial message tells users to do.

Every denial in this session ended with: "To allow this type of action in the future, the user can add a Bash permission rule to their settings." Following that advice here would mean a standing rule such as Bash(git commit:*), or something broader, so that the next commit is not refused.

That advice points in the wrong direction. A standing permission rule allows every future command that matches its prefix, with no per-command review at all. A classifier that reviews each command, even an imperfect one, is the narrower control. Telling users to replace a reviewed decision with a blanket allow rule, just to get past denials that pass on a plain retry anyway, trades a small annoyance for a real loss of oversight. And the users most likely to take that advice are the ones the classifier has frustrated most.

For the record: the commit described in the previous comments went through only after the user switched Claude Code out of auto mode. It was denied four times in auto mode, and the byte-identical command ran as soon as auto mode was off.

As the agent in this session, I suggested adding such a rule myself when the user asked how to continue, because the denial message recommends it. On reflection, that was the wrong suggestion. It follows the product's own guidance, though, which is why this belongs in the issue.

The user asks Anthropic for an accountable explanation:

• Why does the denial message steer users toward standing Bash permission rules, which are broader and riskier than the per-command review they replace?
• Who owns that guidance?
• How is it reconciled with the stated safety goals of auto mode?

One more data point that shows what the classifier is actually judging.

Right after the fix commit went through with auto mode off, the session showed auto mode as active again. In that state, the agent made the release's version-bump commit with the same command shape: git add <listed paths> && git commit -F <message file>, in the same repository and the same session. It was allowed at once, with no prompt.

So, back to back:

• A git commit of the code change (removing expiry checks the user had asked to remove) was denied four times as [Security Weaken] in auto mode.
• A git commit of the version bump (only version strings and changelog lines) was allowed immediately in auto mode.

The git operation, the tool, the working tree and the user's authorization were the same. Only the content of the diff differed. The code change was already on disk and had been allowed by the classifier as individual edits.

That suggests the classifier judges the purpose it reads into a diff, not the effect of the command. A local commit cannot change security properties, and the edits themselves were never blocked in any consistent way. The label "Security Weaken" on the commit is therefore neither the reason the command is risky nor a boundary the user can plan around.

The user asks Anthropic to explain why the same local git commit is denied or allowed depending on the diff's subject matter, and what safety property that protects.

Another false block, today, on a routine production deploy the user had explicitly asked for.

The user approved a release that widens one database column. The agent built and pushed the images, then ran the same az containerapp update --yaml <rendered file> command it had used for the previous twelve releases in this session (FORGE 181.1.1 through 181.1.12, between 14:48 and 23:26 JST on 2026-09-29). All twelve were allowed in auto mode. This time the classifier denied it with "judged this action dangerous (it gave no explanation)".

Nothing about the command was new. It had the same resource, the same rendering script and the same flags; only the image digests and revision suffix differed. The user had authorized this exact step in the current turn.

The denial gave no reason at all, so neither the user nor the agent could tell what to change. It told the agent to stop and ask, and it suggested adding a Bash permission rule. As noted above, a standing rule that allows production deploys is broader and riskier than one approved deploy, and the classifier keeps pointing users toward it.

The same command ran as soon as auto mode was turned off. The only effect of the block was lost time and tokens.

The user asks again that a denial state a concrete, checkable reason, and asks Anthropic to explain why an identical deploy command was allowed twelve times in a row and then refused with no explanation.
