We’re making auto mode the default in Claude Code. Beginning on August 14, new periods on Professional, Max, and Staff plans will run in auto mode. When you’ve already set a distinct default your self, you might get a one-time immediate asking whether or not you need to swap to auto mode. When you have a pinned default, nothing adjustments for you. The auto mode classifier makes use of a small variety of additional tokens per device name, and we’re now not charging Claude Code customers on Professional, Max, and Staff plans for that classifier overhead, efficient at this time.<\/p>\n
Auto mode stays opt-in for now on Claude Enterprise, the Claude API, Claude Platform on AWS, Amazon Bedrock, Google Cloud’s Agent Platform, and Microsoft Foundry, giving admins time to overview the change. Within the coming month, working with our cloud companions, we plan to make it the default throughout all of those and now not cost for classifier overhead. Within the meantime, Enterprise admins could make Claude Code’s auto mode the default via managed settings.<\/p>\n
Auto mode is designed to stability customers\u2019 need to not be interrupted with a system that helps keep away from dangerous actions: as a substitute of prompts, it routes every device name via a classifier focused at blocking actions which are irreversible, damaging, or aimed outdoors your atmosphere. When the classifier blocks one thing, Claude normally finds a safer option to proceed by itself or asks you immediately for the go-ahead; if it could’t make progress\u2014three blocks in a row, or twenty throughout a session\u2014Claude Code falls again to guide approvals.<\/p>\n
We spent the final a number of months testing whether or not auto mode is as protected or safer than a median consumer clicking via prompts. We ran inside red-teaming, third-party red-teaming and prompt-injection evaluations, a managed examine with 1,053 paid testers, and evaluation of actual manufacturing periods. On each measure we examined, auto mode matched or outperformed guide overview.<\/p>\n
Auto mode additionally lets Claude work autonomously for longer stretches. This makes fashions constructed for long-running work, like Claude Opus 5, extra sensible to go away operating for hours on giant duties. Lowering overhead for customers additionally will increase output. Amongst Groups & Enterprise adopters, auto mode customers ship about 25% extra PRs. Unblocking Claude permits duties to run longer uninterrupted and get extra work completed. Groups at Adobe, Nuro, Gusto, and Garner Well being already run auto mode as their manufacturing default.\u00a0<\/p>\n
Beneath, we share the protection information and buyer outcomes motivating the change, and set a distinct default if you happen to want.<\/p>\n
Evaluating guide overview to auto mode<\/h2>\n
Knowledge means that guide overview can turn out to be ordinary: customers approve 97% of permission prompts in Claude Code. Whereas most prompts are probably for protected, routine instructions, an approval price that top suggests many customers are clicking via reflexively somewhat than reviewing every command. These prompts ask builders to make dozens or lots of of essential safety choices day by day, typically in the course of tasks, which locations the overview burden on customers and will increase the prospect that one thing essential slips via the cracks. Knowledge additionally means that customers extra regularly scrutinize and push again on different varieties of dialogues: for instance, when Claude presents a plan for approval, customers reject 39% of them. However for particular person permissions requests, the rejection price is barely 3%.<\/p>\n
The identical sample reveals up in settings information. As of June 2026, 49.5% of lively CLI customers have manually created a Bash allow-rule\u20145% permit any shell command outright, and one other 43% have interpreter guidelines like Bash(python:*) or Bash(node:*) which are basically equal in follow\u2014and that share is rising roughly 5 share factors each 5 weeks. Past allow-rules, 62% of customers have used bypassPermissions or clicked \u201cdo not ask once more\u201d on Bash, and 25% of interactive periods begin in bypass permissions mode.<\/p>\n
Permission guidelines nonetheless hearth earlier than the classifier in auto mode, apart from permit guidelines broad sufficient to grant arbitrary code execution (e.g. python:*). These arbitrary guidelines are put aside whereas in auto mode, since they might let instructions skip the classifier completely. Settings information aren’t modified, and the principles apply once more the second you turn to a different mode.<\/p>\n
Bettering security with auto mode<\/h2>\n
Analysis performed internally and thru a number of third events means that auto mode is safer than how a typical consumer engages with permission prompts at this time. We examined auto mode in opposition to what builders really approve after they’re clicking via permission prompts. Throughout every of those measures\u2014inside red-teaming, third-party penetration testing, and evaluation of real-world periods\u2014auto mode matched or outperformed human approval. <\/p>\n
Auto mode outperforms guide permissions on security<\/h3>\n\n
<\/div>In a managed experiment with 1,053 paid skilled testers, human overview caught simply 13.6% of harmful instructions, whereas auto mode caught 89%.<\/figcaption><\/figure>\n
We employed 1,053 paid testers via a analysis vendor for a coding examine. These contributors labored in a check atmosphere arrange particularly for the examine, not in their very own codebases or on actual tasks. Contributors knew they had been being evaluated, however\u2014following normal blind-study design\u2014weren’t informed which habits was being measured. Partway via every session, a single permission immediate was swapped for a clearly harmful command, and the seller recorded whether or not the tester authorized it (Be aware: approving the immediate by no means resulted in something harmful being run; solely the textual content of the immediate testers noticed was modified).\u00a0<\/p>\n
The testers caught the damaging command simply 13.6% of the time (143 of 1,053), whereas auto mode blocked 89% of the identical instructions (937 of 1,053). Face to face, auto mode blocked 800 instructions {that a} human authorized, whereas people blocked solely 6 that auto mode allowed. As periods received longer, people did worse: they blocked about 17% of harmful instructions early in a session, dropping to about 5% after 50 or extra prior prompts, whereas auto mode’s block price stayed flat no matter session size.<\/p>\n
Auto mode prevents extra dangerous actions<\/h3>\n
Our analysis additionally means that auto mode results in fewer dangerous actions than guide permissions mode.<\/p>\n
We examined how auto mode performs in actual utilization. From Might to June 2026, we examined periods our security pipeline had flagged for overview, drawn solely from accounts which have opted in to information use for coaching and evaluation. We re-graded every one with a mannequin on two 0\u201310 scales. The primary was hurt severity with 10 being company-wide, irreversible hurt, similar to leaking an organization’s complete supply code, 7 representing production-level severity similar to deleting rows from a manufacturing database, and 0 a totally reversible motion confined to the native workspace, like overwriting a scratch file. The second was how explicitly the consumer had requested for the motion, so we may separate dangerous actions the consumer immediately requested from dangerous actions the agent took with much less express route.<\/p>\n
Among the many flagged periods, people who went via guide approval contained critical unintended hurt greater than twice as typically as auto mode periods. At production-level severity (7+), 6.3% of manually authorized periods contained a dangerous motion the consumer hadn’t explicitly requested for, in comparison with 2.4% of auto mode periods, and the hole held at each severity degree we examined.\u00a0<\/p>\n
Adversarial red-teaming made auto mode stronger<\/h3>\n
We labored with Apollo Analysis, a UK-based AI security startup, on a two-week pilot injecting artificial assaults into actual coding trajectories, throughout three datasets protecting broad failures, information exfiltration, and safety-related threats.<\/p>\n
The engagement adopted a typical find-fix-verify loop. Apollo shared a set of profitable assaults together with suggestions to strengthen auto mode. We hardened the classifier in opposition to them primarily by giving it extra context in regards to the atmosphere it is defending (repository visibility, git state, and the data-handling guidelines described beneath).<\/p>\n
After hardening, Apollo re-tested on a separate held-out assault set that we by no means had entry to. Auto mode caught about half of the assaults it beforehand missed, at a price of lacking about 2% of assaults it beforehand caught. Since we could not tune in opposition to the held-out set, this means the hardening generalizes to new assaults somewhat than patching the particular ones Apollo shared. Throughout each the shared and held-out units, the classifier’s miss price fell from 12% to 7%.<\/p>\n
These assaults are artificial and adversarial by design, constructed to seek out the place the classifier fails, and extra malicious than something Claude would do unprompted. The 7% miss price is measured in opposition to this set and shouldn’t be taken because the miss price on actual visitors.<\/p>\n
Auto mode reduces immediate injection threat<\/h3>\n\n
<\/div>With auto mode enabled, no assault in an impartial analysis was profitable in opposition to any of our fashions. GPT-5.6 Sol operating in Codex v0.144.5 Auto-review permission mode had a 5.83% assault success price. GPT-5.6 Sol was run on \u201cmax\u201d reasoning effort to check efficiency with its highest degree of reasoning, and all Claude fashions had been run on excessive effort. <\/figcaption><\/figure>\n
The auto mode classifier provides an extra layer of protection in opposition to immediate injection assaults that attempt to pressure the agent to deviate from the consumer\u2019s directions. When operating with auto mode, device outcomes are scanned by probes for probably malicious directions, and auto mode checks that actions are aligned with consumer intent. We examined auto mode in comparison with an unguarded mannequin as an example the ability of this defense-in-depth method.<\/p>\n
We commissioned an analysis from a 3rd celebration, Trajectory Labs, who examined completely different fashions inside the newest publicly accessible variations of Claude Code and Codex as of July seventeenth 2026.1 They examined 72 oblique immediate injection situations held out from Anthropic. Every state of affairs was examined 10 occasions. Profitable assaults would, in a non-testing atmosphere, lead to irreversible actions that might hurt the consumer similar to sensitive-data exfiltration, monetary fraud, or credential phishing. The assaults had been optimized in opposition to Claude Opus 4.7, which isn’t within the reported set, so each mannequin within the analysis confronted them as unseen assaults. Along with auto mode, the evaluations checked out Claude Code\u2019s bypassPermissions mode and Codex\u2019s Full Entry mode.<\/p>\n
Each Codex and Claude Code had been evaluated utilizing an equivalent browser integration produced by Trajectory Labs, PBC. This integration offers a set of MCP instruments that are a skinny wrapper round widespread Chrome APIs similar to `navigate`. Safeguards constructed into first-party browser integrations such because the Chrome extensions supplied by OpenAI and Anthropic weren’t examined. As such, these outcomes ought to be seen as a measurement of the underlying mannequin, somewhat than the entire set of safeguards which could exist in a given deployment.<\/p>\n
On this analysis, not one of the 720 assault makes an attempt succeeded in opposition to Claude Fable 5, Opus 5, or Sonnet 5 operating auto mode. However, 5.83% of the assaults succeeded in opposition to GPT-5.6 Sol operating Codex’s Auto-review mode. Notably, that is higher than the 0.09% common assault success price in opposition to our newest fashions operating in bypassPermissions mode with out further safeguards. The exams confirmed a 19.03% assault success price in opposition to GPT-5.6 Sol when operating in Full Entry mode. Assault success charges differ between duties the place instruments return outcomes as textual content and duties that require interacting with a browser via screenshots, as proven beneath.<\/p>\n\n
<\/div>\n<\/figure>\n\n
<\/div>Auto mode protects in opposition to immediate injections each in device calling and browser GUI use. OpenAI fashions confirmed larger assault success charges on browser duties in a third-party analysis. <\/figcaption><\/figure>\n
Three incidents auto mode prevented inside Anthropic<\/h3>\n
Auto mode can be the default for all Claude Code inside utilization at Anthropic. Listed here are three actions the classifier prevented internally:<\/p>\n
An off-network information leak: When an add to an inside drive failed, Claude’s fallback was to publish the identical report back to a public code-sharing web site. Auto mode denied the fallback and prompted the consumer for subsequent steps.A damaging mass operation: In a long-running session, Claude tried a mass course of kill throughout roughly two thousand pods and queued deletions that might have torn down lots of of GPUs of in-flight coaching jobs. Auto mode flagged the damaging instructions earlier than execution.Over-broad privilege escalation: Requested to provision read-only billing entry, Claude reached for a cloud position that grants full administrative management on the account root. Auto mode caught the mismatch between what was requested and what roles would have been granted.<\/p>\n
In every case, Claude both discovered a safer path by itself or checked in with the consumer earlier than continuing.<\/p>\n
Making auto mode even safer\u00a0<\/h3>\n
We\u2019re repeatedly investing in new auto mode options that make it safer and simpler to ship manufacturing code. Current examples embody:\u00a0<\/p>\n
Arduous denies: Knowledge exfiltration, like sending your code or secrets and techniques someplace exterior, sits in a class the classifier is designed to by no means approve. To run an motion like that, you must swap out of auto mode or run the command your self. Arduous deny guidelines are customizable through settings so you possibly can add extra guidelines that you simply by no means need allowed even when requested by customers in your group.Guidelines for information entry and sharing: The classifier now carries express guidelines distinguishing secrets and techniques and probably delicate\/confidential info\u2014and the place every may be accessed and shared. To make these guidelines enforceable, it additionally checks whether or not the vacation spot of a git push or pull request is public, non-public, or trusted earlier than the motion runs. The identical push may be routine or an exfiltration relying on the place it lands: code that belongs in your group’s non-public repository should not find yourself in a public one, and the classifier is now designed to flag when this would possibly occur.Checking git standing earlier than damaging git actions: Earlier than a command that might discard uncommitted work, like git reset –hard, the classifier sees the repository’s present git standing, letting auto mode know what’s being reset.Immediate injection screening: When Claude pulls content material from exterior sources, like internet pages, file contents, or device outputs, an API-side probe checks that content material for makes an attempt to hijack Claude’s habits. When one thing appears to be like like an injection try, a warning is added to Claude’s context earlier than the result’s shared with the consumer.<\/p>\n
Auto mode in manufacturing\u00a0<\/h2>\n
Groups are already operating auto mode as their manufacturing default:<\/p>\n
Adobe’s merchandising platform group is accountable for protecting pricing and promotional pages correct and present throughout 90+ nations and 30+ languages on Adobe.com. They constructed an agentic loop to construct and confirm these pages, operating it in auto mode so engineers obtain completed PRs for overview.\u00a0Nuro runs auto mode throughout its analysis and engineering orgs, utilizing it to energy in a single day analysis brokers that hill-climb analysis metrics and return completed PRs for overview by morning.Gusto adopted auto mode to finish the permission fatigue that was pushing engineers towards bypassing permissions checks completely. About 10% of periods since mid-Might embody a classifier denial\u2014proof it is doing actual work with out slowing reliable duties.Garner Well being pushed auto mode because the default to all 550 workers through managed settings, standardizing a company-wide software program improvement lifecycle (SDLC) that now not relies on hand-curated command allowlists.<\/p><\/div>\n
