Claude Code V2.0.55 Bug: Usage Plan Starts On Launch

Is the latest version of Claude Code triggering your usage plan as soon as you launch the application? You're not alone. This article dives deep into a newly reported bug in Claude Code v2.0.55 where the usage plan unexpectedly initializes upon launching the application, even without actively using it. We'll explore the details of this issue, its impact, reproduction steps, and potential workarounds.

Understanding the Issue: Usage Plan Overload

This bug specifically affects users with Pro usage plans in Claude Code. In previous versions, users could launch Claude Code, adjust settings, and exit without initiating a usage plan session. However, in version 2.0.55, the application immediately registers usage upon launch, consuming a portion of the plan's allowance and starting the countdown timer. This behavior is a significant departure from the expected functionality and raises concerns about unintended usage consumption.

The primary symptom of this bug is that upon launching Claude Code v2.0.55, the user's usage plan shows an immediate increase (reportedly around 1%) and an active session timer, even if no actual coding or task execution has occurred. This means that the user's allocated usage time is being depleted simply by opening the application, which can be frustrating and lead to premature exhaustion of their plan limits. Understanding this unexpected behavior is crucial for users to manage their usage and avoid unwanted charges or limitations.

Users rely on their usage plans to effectively manage their resources and projects within Claude Code. The sudden and unexpected consumption of usage upon launch undermines this planning and budgeting process. For instance, a user who only wants to quickly check settings or explore the interface might find that a portion of their plan has already been consumed before they've even started working on their tasks. This can create a sense of urgency and pressure, as users may feel compelled to immediately engage in coding activities to justify the already-consumed usage. Furthermore, it can disrupt workflows, as users need to be extra cautious about launching the application, potentially delaying or complicating their project timelines.

Detailed Bug Report: Preflight Checklist and Problem Description

The user who reported this bug diligently followed a preflight checklist, confirming that they had searched existing issues to ensure it wasn't a duplicate report, that this was a single bug report, and that they were using the latest version of Claude Code. This level of detail is invaluable for developers in diagnosing and addressing issues effectively. The user clearly stated the problem: launching Claude Code v2.0.55 automatically initializes their Pro usage plan, resulting in a 1% usage display and an active countdown timer, contrasting with previous versions where launching the application didn't trigger a session.

The expected behavior, as highlighted by the user, is that Claude Code should launch without immediately starting a session. This allows users to configure settings, check options, or explore the interface without consuming their plan's usage allowance. The deviation from this expectation is what makes this a significant bug, impacting the user experience and potentially the cost-effectiveness of using the Pro plan.

This unexpected behavior disrupts the user's workflow and potentially wastes valuable usage time. For example, a user might want to quickly launch Claude Code to adjust some settings or review their project configurations before committing to a coding session. In previous versions, this was a seamless process that didn't impact their usage plan. However, with the new bug, simply launching the application initiates a session, consuming a portion of their plan's allowance and starting the countdown timer. This can create a sense of pressure and anxiety, as users may feel compelled to start coding immediately to make the most of the session, even if they only intended to perform a quick task.

Reproducing the Bug: A Step-by-Step Guide

The bug report provides a clear and concise set of steps to reproduce the issue, which is crucial for developers to verify and fix the problem. The steps are:

1. Ensure you have a fresh, unused session on a Pro plan.
2. Check "Plan Usage Settings" in your Claude account to confirm 0% usage and no active session.
3. Launch Claude Code v2.0.55 and check usage.
4. Observe that usage shows 1% and an active session started upon launch.

These steps effectively isolate the bug, demonstrating that simply launching the application triggers the usage plan initialization. This level of clarity is essential for efficient debugging and resolution.

Each step is designed to isolate the conditions under which the bug occurs. By starting with a fresh, unused session, the user ensures that the observed behavior is directly attributable to the launch of Claude Code v2.0.55, rather than any residual state from a previous session. Checking the "Plan Usage Settings" beforehand provides a baseline measurement, confirming that there is no active session and that the usage is indeed at 0%. This step is critical for verifying that the bug is consistently reproducible and not influenced by external factors.

By following these steps, other users and developers can consistently replicate the bug, confirming its existence and facilitating the process of finding a solution. This reproducibility is a key factor in efficient bug fixing, as it allows developers to reliably test their fixes and ensure that the issue is fully resolved.

Key Details: Model, Regression, and Environment

The bug report includes important details about the Claude model being used (Sonnet, the default), confirming that the issue isn't specific to a particular model. It also identifies this as a regression, meaning it worked in a previous version (2.0.52), which helps narrow down the potential cause. The user's environment is also clearly stated: macOS, Terminal.app, and Anthropic API. This comprehensive information helps developers target their investigation and testing efforts.

The identification of this bug as a regression is particularly significant. A regression bug is one that was not present in a previous version of the software but has been introduced in a later version. This means that something in the codebase has changed between versions 2.0.52 and 2.0.55 that is causing the issue. By pinpointing the bug as a regression, developers can focus their attention on the changes that were made during this period, making it easier to identify the root cause. This focused approach can save a significant amount of time and effort in the debugging process.

The detailed environment information further aids in the debugging process. The fact that the user is running macOS and using Terminal.app provides clues about the potential interactions between Claude Code and the operating system. If the bug is specific to certain environments, this information can help developers create targeted fixes. For example, if the bug is only reproducible on macOS, developers might look for issues related to the way the application interacts with the macOS system libraries or frameworks. Similarly, knowing that the user is using the Anthropic API is important because it indicates the communication channel through which Claude Code is interacting with the cloud service. If the bug is related to API interactions, developers can examine the API calls and responses to identify any anomalies.

Impact and Potential Workarounds

The immediate impact of this bug is the unintended consumption of usage plan allowances. Users may find their Pro plan limits being depleted faster than expected, potentially leading to additional costs or service interruptions. A potential workaround, though inconvenient, might be to avoid launching Claude Code unless actively intending to use it, minimizing the unintentional usage. However, a proper fix from the developers is crucial for a seamless user experience.

The potential workaround of avoiding launching Claude Code unless actively using it highlights the severity of the issue. While this workaround can mitigate the immediate impact of the bug, it's not a long-term solution. It disrupts the user's workflow and adds an unnecessary layer of complexity to the process of using Claude Code. Users should be able to launch the application without having to worry about their usage plan being unintentionally consumed. The ideal solution is a fix from the developers that addresses the underlying cause of the bug and restores the expected behavior of the application.

The unintentional usage of plan allowances not only has financial implications but can also cause frustration and inconvenience for users. Users who rely on Claude Code for their work or personal projects need to be able to manage their usage plans effectively. A bug that consumes usage without the user's explicit action undermines this ability and can lead to disruptions in their work. For example, a user who is nearing their plan limit might be hesitant to launch Claude Code for even a quick task, fearing that they will exceed their limit and face additional charges or service restrictions. This can create a sense of anxiety and limit the user's ability to fully utilize the application.
