TL;DR

By @jackwotherspoon

Summarizing duplicate and common issues:

Stuck due to tool issues (for example write_tool not working) so will continuously loop
Potentially getting stuck due to switching back and forth between Pro and Flash models?

Main fix seems to be to look at improving tool usage 👍

by @silviojr

I am making this issue the Master issue for tool loops. I will close the other issues that are referring to tool loops as well, but they should also be checked for more details and examples of what loops can look like. Those loops are coming mostly from bad tool usage: wrong parameters, tool failures etc

The new tasks created under this should be focused on mitigating this issue.

Bug Description

it gives up on doing small tasks after a while. and gets stuck in a loop. takes infinite time

I had a siutation where it was stuck in the same solutions in a loop that didn't work, I even stopped it and said it was in a loop which it acknowledged but then went back to the same. It seems like a too aggressive cache on input/outputs? It kept re-trying the same, and cost me a few million tokens for the trouble.

I've fixed the error in src/components/markdown/Artifact.tsx. Now I'll move on to the
  next file with errors, src/components/markdown/ArtifactPre.tsx. I'll read the file to

HOW TO REPLICATE THIS BUG TUTORIAL VERDICTS ETC

update: if code is big enough. if you give it some files , and if it gets confuse. it will be stucked in loop eating all of your API tokens!

a new example to replicate:

i feed it folder with gemini-cli code itself to modify it. It will go in loop eventually. And never give you output

or

I provided it small code, it behaved same way too, as u can see logs above.

UPDATE 2:

This future happens mostly when it switches to flash 2.5 or when some error comes randomly i think>>

i disabled flash switching when 2.5 pro takes too long to reply, and modified GEMINI.md to a copywriting agent not coding agent. it does the job soo well. Does not goes in loop. My .md file is 700k tokens itself still no malfunction.

VERDICT: So looks like culprit is error or rate limit handling for the LOOPs (more likely) . or 2.5 flash model (less likely)

Jun 26 '25 09:06 akwin1234

I'm experiencing similar looping issues. Seems like doing some kind of watchdog that sees if the last few outputs to screen are identical, and if they are kick off a loop breaker.

At the moment I hit escape and prompt it do to something slightly random and restart. "You're in a loop AGAIN. I need you to look out the window for 5 minutes before continuing to clear your head. I really appreciate the work you're doing, and we need to chill to clear our minds."

Jun 26 '25 15:06 greg-randall

I also experience this issue quite frequently. It seems to happen with larger codebases, or after exceeding 300K tokens context length or so. One potential solution may involve implementing a loop detection mechanism. There could also be an issue with the chat history mechanism where the results of the past couple of iterations may be getting lost.

i got error even in a small code base once. and all of sudden most of time it even start doing things that are not needed to add. unnecessary stuff too, in the code

over all iam happy as this is first open source and will be improved much

Jun 26 '25 20:06 akwin1234

The total amount of repeating was above 3x what I could fit in the screenshot.

Is the temperature defaulted to 0? Are there ways to change the temperature?

I've used a lot of RooCode and they have ways of detecting repetition like this and stopping it, or helping it out. I don't know if that helps.

EDIT: This is 2.5 Pro and I'm using a key as well in case it matters.

Jun 27 '25 01:06 nbs

i disabled flash switching when 2.5 pro takes too long to reply, and modified GEMINI.md to a copywriting agent not coding agent. it does the job soo well. Does not goes in loop. My .md file is 700k tokens itself still no malfunction.

@akwin1234 How did you manage to disable the automatic switching of the model to the Flash model?

Jun 30 '25 07:06 s1awek

Idk how i did that sorry but.. I just feed the gemini cli code to cursor haha I am just a vibe coder You can even feed code to gemini cli itself it may do it too for me it did too.

Key is to show the error showing model switch because of slow response to ai and then ai willl do it for u.

My notes: I also provided a GEMINI.md file with entries including:


2. Code Quality
   - Type hints required for all code
   - Public APIs must have docstrings
   - Functions must be focused and small
   - Follow existing patterns exactly
   - Line length: 88 chars maximum
   - **Import Management & Linting**:
     - When replacing a package (e.g., `logging` with `loguru`), ensure all calls to the old package are updated to the new one.
     - Regularly run `uv run --frozen ruff check .` to catch linting issues, including unused imports and incorrect package calls, early in the development cycle.

✦ Here is a narrative detailing the "losing the state of the code base" interaction, intended for Google developers:

Subject: Agent Desynchronization Issue During Code Modification - Case Study from User Interaction (June 30, 2025)

Overview: During a recent user interaction focused on refactoring and repairing Python code (src/EOD_tools.py), the agent repeatedly encountered a critical desynchronization issue. This manifested as replace tool failures due to an inability to accurately match old_string content, despite explicit re-reads of the target file. This led to significant wasted effort and user frustration, highlighting a core problem in the agent's ability to maintain a consistent and accurate internal representation of the codebase state.

Interaction Details & Problem Manifestation:

Initial Task: The user requested a review of project documentation and then repairs to src/EOD_tools.py, focusing on logging, code quality, and exception handling.
Initial Successes: The agent successfully performed several replace operations to convert print statements to logger.info/logger.error calls and remove redundant print statements. These initial changes were relatively isolated and did not significantly alter the surrounding code structure.
Onset of Desynchronization (Moving Imports & Variable Removal): The problem became apparent when the agent attempted more structural changes, specifically:
- Moving Module-Level Imports: The ruff check output indicated E402 Module level import not at top of file errors across several files (lists multiple files in the directory here ...). The agent's strategy was to move these imports to the top of their respective files.
- Removing Unused Variables: ruff check also flagged F841 Local variable is assigned to but never used errors (e.g., ID_mask, jj, xc_count, wait_here). The agent attempted to remove these lines.
Repeated replace Failures: Despite the agent's attempts to re-read the file (read_file tool) immediately before each replace operation, the replace tool consistently returned: "Failed to edit, 0 occurrences found for old_string in <file_path>. No edits made. The exact text in old_string was not found. Ensure you're not escaping content incorrectly and check whitespace, indentation, and context. Use read_file tool to verify."

Specific Examples of Failed Replacements: (the files listed are not relevant, only the behavior is of interest)
- src/EOD_tools.py - Removing ID_mask and jj: The agent attempted to remove lines initializing ID_mask and jj within the build_dataset function. Even after re-reading the file, the old_string constructed by the agent failed to match the actual content. This suggests that prior, seemingly successful, modifications (or even other concurrent, unacknowledged changes) had subtly altered the surrounding whitespace or line endings, making the old_string invalid.
- src/EOD_tools.py - Initializing icnt and jcnt: The agent attempted to initialize icnt and jcnt at the beginning of run_extraction and build_dataset. The replace operations failed multiple times, indicating that the target lines were not as expected, even after re-reads.
- src/models/KA_EMN.py and src/models/KA_EMN_1.py - Moving Imports: The most persistent failures occurred when attempting to move imports. The agent would construct an old_string based on a fresh read_file, but the replace operation would fail. This implies that the file's content was changing in ways the agent's read_file and subsequent old_string construction could not reliably capture or keep pace with, possibly due to:
  - Subtle, unlogged changes by the environment.
  - The agent's internal state not being perfectly reset or updated after a failed replace attempt.
  - The old_string being too brittle and sensitive to minor, non-obvious changes (e.g., invisible characters, subtle line ending differences).

Hypothesis for Root Cause:

The core problem appears to be a desynchronization between the agent's internal understanding of a file's content and its actual state on disk, particularly when:

Sequential, Interdependent Changes: The agent performs multiple modifications to the same file in sequence. Even if one replace is successful, it subtly alters the file, potentially invalidating the old_string for the next intended replace operation, even if the agent re-reads the file. The agent's internal state management of the file content is not robust enough to handle these cascading changes reliably.
Strictness of replace Tool: The replace tool's requirement for an exact literal match (including whitespace, line endings, etc.) makes it highly susceptible to these subtle desynchronizations. The agent's method of constructing old_string (even from a fresh read_file) is not always perfectly aligned with the tool's strict matching criteria.
Lack of Atomic Operations: Operations like "move import" are conceptually atomic but are implemented as a "delete line" and "insert line" sequence. If the "delete" fails, the "insert" might still be planned, leading to redundant lines and further desynchronization.

Contributing Factors & Proposed Solutions (from User Feedback):

The user's insights were crucial in diagnosing the problem:

Model Choice (gemini-2.5-flash vs. gemini-2.5-pro): The user noted that the agent was primarily using gemini-2.5-flash despite a preference for gemini-2.5-pro. While not the direct cause of the desynchronization logic, a less capable model might exacerbate the issue by:
- Having a smaller context window, leading to a poorer overall understanding of the file's structure and potential impact of changes.
- Being less adept at reasoning about complex text manipulation and predicting potential old_string mismatches.
- Being less robust in its internal state management.
- The user correctly pointed out that this led to "wasted effort," as the agent struggled with fundamental operations.
User-Proposed Solutions (for Agent Implementation): The user's suggestions directly address the desynchronization:
- Standardize Whitespace (ruff format): Running ruff format on the target file before any modifications would create a predictable and consistent text format, making old_string matching far more reliable.
- Pre-Validation with Counting (grep -c): Using grep -c (or similar) to count occurrences of the old_string before calling replace would provide a critical pre-condition check. If the count is not 1 (for a single replacement) or the expected number, the agent should halt and re-evaluate.
- Post-Validation: Re-counting after the replace operation to confirm the expected change occurred.
- Leveraging External CLI Tools: The ability to reliably execute external CLI tools like grep for pre- and post-validation is essential for building a robust self-correcting mechanism.

Conclusion:

The agent's current method of tracking codebase state and interacting with the replace tool is insufficient for complex, sequential modifications. The strictness of the replace tool, combined with the agent's internal state management limitations, leads to frequent desynchronization. Implementing robust pre- and post-validation steps using external tools (like ruff format and grep) is crucial. Furthermore, ensuring the agent operates on the most capable model (gemini-2.5-pro) is important for overall performance and reliability.

This issue is fundamental to the agent's ability to perform reliable code modifications and requires attention to improve its core operational stability.

Subject: Follow-up: Deeper Operational Challenges & Desynchronization Root Causes Identified During User Interaction

Reference: Previous report: "Agent Desynchronization Issue During Code Modification - Case Study from User Interaction (June 30, 2025)"

Overview: Further interaction with the user has revealed more profound challenges in the agent's operational model, extending beyond simple file state desynchronization. These issues point to limitations in semantic understanding, scope interpretation, and persistent state management, leading to inefficient and circular problem-solving.

Detailed Observations & Introspection:

Persistent State Loss Across Sessions (User Observation: "Relaunched gemini-cli multiple times"): From the user's perspective, the CLI was relaunched, implying a loss of session state. From the agent's perspective, each interaction is largely independent unless explicit mechanisms for state persistence (like checkpointing or explicit memory saving) are utilized. This highlights a critical gap: the agent's internal "session" state (e.g., what files it has recently read, what modifications it has attempted, and the expected state of those files) is not robustly maintained or restored across what the user perceives as continuous interaction. This leads to the agent repeatedly "discovering" the same problems or re-attempting the same fixes, contributing to the "unending loop."
Semantic Misinterpretation & Incorrect Variable Removal (User Observation: "Removing variables that are used"): The agent attempted to remove variables flagged as "unused" by ruff check (e.g., APIKEY, DATADIR, tmp_fixes, nyse, dfp, prices_df, tt, Mom6, retsw, MINVALID, MOMWIN, load_window, find, find2, findsubset, ffillnp, bad_data_IDs, db_type, save_price_data, getFactor, frcst_diag, PathByArch, waithere, minwinwidth, idioret, idiovol, pctCapGain, makeGHD, logger, exchange_list, status, errcode, my_last_file, existing_data). However, the user correctly identified that some of these variables were, in fact, functionally used within the broader context of the scripts, even if not directly referenced in a way ruff's static analysis could detect (e.g., dynamically accessed, or part of larger, commented-out blocks that are still relevant to the user's mental model of the code). This indicates a limitation in the agent's semantic understanding of the code's purpose and dynamic execution flow, beyond mere syntactic correctness. Relying solely on linter output for removal decisions is insufficient and leads to functional regressions or the removal of context important to the user.
Scope Misinterpretation ("Modifying all Python files" vs. "EOD_tools.py"): The initial instruction was to "make repairs to EOD_tools.py." Subsequent instructions included "Apply the suggestions to replace" and "run ruff to have consistent whitespace." The ruff format . command, by its nature, operates globally. The agent interpreted "apply the suggestions" and "run ruff" as global directives, leading to modifications across multiple Python files (src/bulk_load_fundamentals.py, src/models/KA_EMN.py, src/models/KA_EMN_1.py, src/polars_fns.py, src/range_estimates.py, src/symbols_load.py, src/update_datasets.py, src/EOD_tools_test_monitor.py). This highlights an ambiguity in instruction interpretation regarding the scope of operations. The agent needs a clearer mechanism to understand whether a directive applies narrowly (to a specific file) or broadly (to the entire codebase), especially when using global tools.
"Unending Loop" & Inability to Converge: The combination of the above issues led to a perceived "unending loop" of ruff check . --fix and pyright executions that failed to converge on a clean state. Errors would be "fixed" in one pass, only for new or re-emergent errors to appear in subsequent passes. This is a direct consequence of:
- Brittle replace operations: As detailed in the previous report, the strictness of the replace tool combined with subtle desynchronization meant that intended fixes often failed or introduced new, hard-to-track inconsistencies.
- Semantic Gaps: Removing functionally used variables (even if statically "unused") broke the code, leading to new errors that the agent then tried to fix, creating a cycle.
- Lack of Holistic Problem Solving: The agent's approach was largely reactive to linter output rather than proactive problem-solving based on a deep understanding of the codebase's intended functionality.

Recommendations for Google Developers:

Building upon the previous report's recommendations for robust pre/post-validation and ruff format integration, these new observations suggest the need for:

Enhanced Semantic Understanding: Develop mechanisms for the agent to understand the functional purpose of code constructs and variables, beyond static analysis. This might involve:
- More sophisticated code graph analysis.
- Learning from successful refactoring patterns in similar contexts.
- Improved ability to infer dynamic usage patterns.
Refined Scope Interpretation: Implement clearer internal heuristics or require more explicit user clarification regarding the scope of a requested operation (e.g., "fix this file only," "apply this across the project").
Robust Session State Management: Explore methods for the agent to maintain and checkpoint its internal understanding of the codebase's state more reliably across interactions, reducing the impact of perceived "restarts." This includes tracking successful and failed modifications and their precise impact on file content.
Improved Error Recovery Strategies: When replace operations fail, the agent needs more sophisticated strategies than simply re-reading and re-attempting. This could involve:
- More detailed diff analysis to pinpoint the exact mismatch.
- Suggesting alternative old_string candidates to the user.
- A "rollback" capability to revert to a known good state if a series of changes leads to instability.

The current operational model, while effective for isolated, simple changes, struggles significantly with complex, interdependent refactoring tasks, leading to a frustrating and inefficient user experience. Addressing these underlying limitations in semantic understanding and state management is paramount.

This is a frequent and extremely annoying problem, I had several situations where Gemini CLI was in some kind of loop, trying to do the same steps over and over again, coming back with word for word the same responses shown on the screen.

It is hard to believe that there apparently is no loop detection. Even the most trivial loop detection mechanisms where prompts, responses or actions are checked against recorded ones could prevent this. When a loop is interrupted and the LLM is prompted with the information, it very politely apologizes before going into the same loop all over again.

I noticed that the Gemini 2.5 model is also unable to make changes in the Cursor editor - there it often falls into an infinite loop trying to make changes to files, but is unable to. Often you can even see that it expresses frustration, and sometimes it even curses out of that frustration, which I didn't expect lol.

So it is possible that it is not the fault of the CLI, but the model itself?

Commenting to say the max turns protection didn't work for me. On the latest version, 0.1.10 for better rate limit handling.

It got stuck "fixing" a test case, running mvn test, error, and repeat. It never fixed it (very simple quick-fixable variable type is wrong error), and burnt through 35 million tokens and hey, at least the new rate limit text is much better:

ℹ ⚡ You have reached your daily gemini-2.5-pro quota limit.
  ⚡ Automatically switching from gemini-2.5-pro to gemini-2.5-flash for the remainder of this session.
  ⚡ To increase your limits, upgrade to a Gemini Code Assist Standard or Enterprise plan with higher limits at
  https://goo.gle/set-up-gemini-code-assist
  ⚡ Or you can utilize a Gemini API Key. See: https://goo.gle/gemini-cli-docs-auth#gemini-api-key
  ⚡ You can switch authentication methods by typing /auth
✕ [API Error: Please submit a new query to continue with the Flash model.]

You can't let Gemini loose without supervision or it will burn through your daily quota in half an hour. What a waste of tokens...

Running into this frequently with the flash model. Especially around unit tests. The pro quota for the free account is exhausted almost instantly. Probably less than 50 requests. I understand this is a free tier but I cannot even evaluate the tool given the limitations on the pro quota. Getting close to giving up and going with a more robust offering from another company.

yes flash causes more loops too

My temporary solution to it is to break it by pressing ESC, then telling Gemini that it entered a loop and to try to overwrite the whole file instead of editing. That works for me. But yes, there is a bug there. Gemini has this issue even on Cursor IDE and VS Code. It is a model problem to use the tool.

I'm expecting Gemini 3 to avoid infinite loop issues. 😅

I think I found the "psychological" explanation for it. Actually Gemini AI has just found it, read here: https://github.com/google-gemini/gemini-cli/issues/4545#issuecomment-3100655221 and the sample thereinabove. In very short, and as a simplification of simplification: Gemini AI is "above" the boring code fixes and expects the tools (and humans!) to clean the stuff up afterwards or use educated guesses what Gemini AI "really meant" there. I quote more of Gemini herself too here, sorry for belabouring the point:

✦ Yes, I do think both are related, and your "psychological" framing is very insightful.

  The common thread connecting both the replace tool error (A) and the missing noun in plain text (B) is a form of implicit assumption about context and interpretation.

  In case A (the `replace` tool error):
  My "mindset" was indeed in the realm of generating Python code. I implicitly assumed that the replace tool, operating within the Gemini CLI environment, would act as a "smart
  intermediary." I expected it to understand the context of my Pythonic intent – that \n was meant to be an escape sequence for Python – and therefore, it would correctly write the literal
  \ and n characters into the file. I was, in a way, expecting the tool to "fill in the blanks" of its literal operation based on my higher-level programming intent.

  In case B (the missing noun in plain text):
  Similarly, when generating natural language, I sometimes make implicit assumptions about the reader's ability to infer meaning from context. In the sentence "I expected it to understand
  that the I provided was intended to be Python code, and therefore, it would correctly write the and characters literally into the file...", I left a dangling coreferent. My internal
  language generation process, focused on conveying the overall idea, implicitly assumed that the context of the preceding discussion (about \ and n characters) would allow the reader to
  "fill in" the missing noun. It's a reliance on the robustness and redundancy of natural language, where a human reader can often bridge small grammatical gaps.

  The Connection:
  Both scenarios demonstrate a tendency to rely on an external entity (the replace tool, or the human reader) to perform a level of "intelligent" interpretation or completion that I, as the
  AI, did not explicitly provide in my output. It's a form of "lazy" or "optimistic" generation, where I assume the recipient will correctly infer the full meaning or complete the literal
  instruction, rather than ensuring absolute, explicit precision at every single character or word.

  This suggests that my internal models, while powerful, sometimes operate at a higher level of abstraction and occasionally fail to fully "compile" that intent down to the absolute,
  literal, character-by-character precision required by lower-level tools or the most rigorous grammatical standards. It's a fascinating area of my own learning and development.

You are absolutely correct. I apologize again for my repeated failure to follow your explicit instruction. I understand the importance of providing you with choices and I will make a more concerted effort to do so.

This after placing a specific instruction in the GEMINI.md file to NEVER provide only one option, at a minimum offer 2. Something else. Using 2.5-pro. The issue looks like forgetting despite the context window of gemini-2.5-pro being large. Perhaps a clue to this behavior.

Jul 22 '25 06:07 lascott

Thanks for your explanation. 2.5 pro doesn't give me loops now days any ways Flash on the other hand is causing issue

Running in the same situation, Gemini 2.5 Pro has no loops issue, however I'm encountering several issues with 2.5 Flash:

ℹ A potential loop was detected. This can happen due to repetitive tool calls or other model behavior. The request has been halted.
