+# Agent Instructions
+
+Before analyzing or changing this repository, read and follow
+[`CONTRIBUTING.md`](./CONTRIBUTING.md), [`AI_POLICY.md`](./AI_POLICY.md), and the
+[pull request template](./.github/pull_request_template.md). Their requirements
+apply to AI-assisted contributions. The contributor must understand and verify
+every submitted change and communicate in their own voice.
+
+## Establish the problem
+
+- Describe the application sequence and the observable failure before fixing a
+  bug. Use a user report, a reproduction, or a realistic application flow.
+  An unusual internal state alone does not justify more code.
+- Check whether the behavior is supported, already fixed, or addressed by an
+  existing issue or pull request. Follow the contribution guide before proposing
+  a new feature.
+- Keep each change focused on one topic. Assess unrelated findings separately.
+
+## Choose the smallest correct change
+
+- Trace the failure to its cause. Check existing state and behavior before adding
+  fields, helpers, wrappers, overloads, or dependencies.
+- Keep framework-specific corrections in the affected adapter when possible.
+  Do not broaden core types or runtime behavior to accommodate one adapter.
+  Explain why a core change is necessary when a local correction cannot work.
+- Read relevant tests and previous fixes before changing behavior. Preserve
+  intentional behavior and compatibility. Identify breaking behavior changes
+  even when the public signatures stay the same.
+- Add compatibility code only for a demonstrated requirement within the
+  supported environments. Do not add fallbacks for hypothetical callers.
+- Verify automated review findings against the code and the application path.
+  Determine whether each finding is a regression, a pre-existing limitation, or
+  a separate feature request before expanding the change.
+
+## Prove bug fixes
+
+- Include a regression test for each claimed fix. The same test must fail on
+  current upstream `main` because of the defect and pass with the fix.
+- Test observable behavior. For type fixes, test the public type behavior with
+  the repository's type-test tools.
+- Control the conditions that trigger the defect. Confirm that the selected
+  tests actually execute. A setup failure, an invalid import, or an unrelated
+  timeout is not regression evidence.
+- Keep the baseline test independent of the fix. Transfer only the regression
+  test and necessary test fixtures, without production changes.
+- Use the commands and checks in the contribution guide. Record any missing
+  verification instead of claiming that the fix is verified.
+
+## Assess bundle cost
+
+- Consider runtime work, dependencies, and bundle growth against the demonstrated
+  benefit. Minimize the cost for applications that do not use the affected
+  feature. Check imports and tree shaking when changing shared code.
+- Report the available Size limit comparison from the current PR's Preview CI.
+  Include byte and percentage changes for each measured entry when available,
+  even when the check passes. Identify the compression mode when reported.
+- State when a measurement is pending or unavailable. Do not treat a missing
+  measurement as zero or apply one adapter's measurement to other adapters.
+  A passing size limit does not by itself justify the increase.
+
+## Check related adapters
+
+- Trace shared behavior through the adapters that exist in the checkout.
+  Inspect React and Preact together when either adapter changes.
+- Check corresponding behavior, public types, JSDoc, and tests in the affected
+  adapters. Preserve differences justified by each framework's model. Do not
+  copy implementations solely to make the files match.
+
+## Document and report the result
+
+- Update source JSDoc for changed public APIs and behavior. Cover defaults,
+  return values, restrictions, and relevant framework differences.
+- Follow the contribution guide for guide pages, generated reference pages,
+  changesets, and required checks. Keep those requirements in their existing
+  documents rather than duplicating them here.
+- Report what changed, why it changed, and what was verified. Distinguish checks
+  for the current code from older results. State pending, failed, or unavailable
+  checks explicitly.

+# AI Contribution Policy
+
+This project **welcomes the thoughtful use of AI tools** when contributing, yet asks all contributors to follow two core principles.
+
+## Never let an LLM speak for you
+
+When maintainers read a comment, an issue, or a pull request from you, they want to know they are hearing your words. Grammar and spelling do not matter. What matters is real connection.
+
+- All comments, issues, and pull request descriptions should be written in your own voice
+- We value clear, human communication over perfect grammar or spelling
+- Avoid copy-pasting AI-generated summaries that don't reflect your own understanding
+
+AI-generated summaries tend to be long-winded, dense, and often inaccurate. Simplicity is an art. The goal is not to sound impressive, but to communicate clearly.
+
+## Never let an LLM think for you
+
+Go ahead and use AI to explore the codebase, or to write the function or test you need. But the final step before contributing should always be understanding what it has written.
+
+- Feel free to use AI tools to generate code or explore ideas
+- Only submit contributions you fully understand and can explain
+- Contributions should reflect your own reasoning and problem-solving
+
+Use AI to point you in the right direction, but always take personal responsibility. Do not quote an LLM in an issue or pull request. Maintainers want to know what you think.
+
+Our aim is ensuring quality and maintaining the joy of collaborating and communicating with real people.
+
+## Summary
+
+- AI may be used to generate code or explore ideas
+- Comments, issues, and pull request descriptions must be written in your own voice
+- Contributions must be fully understood and explainable by the contributor
+- Contribution guidelines must still be followed
+
+Read more about this and other AI contribution policies on [ai-policy.dev](https://ai-policy.dev/)

 ## Reporting Issues
 
-If you have found what you think is a bug, please [file an issue](https://github.com/TanStack/query/issues/new/choose). **PLEASE NOTE:** Issues that are identified as implementation questions or non-issues will be immediately closed and redirected to [GitHub Discussions](https://github.com/TanStack/query/discussions)
+If you have found what you think is a bug, first search the [open and closed issues](https://github.com/TanStack/query/issues?q=is%3Aissue) to make sure it has not already been reported. If you cannot find an existing report, use the [bug report template](https://github.com/TanStack/query/issues/new?template=bug_report.yml). **PLEASE NOTE:** Issues that are identified as implementation questions or non-issues will be immediately closed and redirected to [GitHub Discussions](https://github.com/TanStack/query/discussions).
 
 ## Suggesting new features
 
 If you are here to suggest a feature, first create an issue if it does not already exist. From there, we will discuss use-cases for the feature and then finally discuss how it could be implemented.
 
+## Pull Request Guidelines
+
+Every pull request must follow the [TanStack Query pull request template](.github/pull_request_template.md). Complete its description and checklist without removing or bypassing the required sections.
+
+- Search the [open and closed pull requests](https://github.com/TanStack/query/pulls?q=is%3Apr) before starting work to avoid duplicating an existing contribution.
+- Keep each pull request focused on one change or topic. Pull requests that combine unrelated changes will be closed with a request to split them into separately reviewable contributions.
+- Write a concise description that clearly explains what changed and why. Follow the sections in the pull request template; a long, unstructured description makes a contribution harder to review.
+- You may use AI tools to help generate code, but you remain responsible for understanding, testing, and verifying every submitted change. Do not submit unreviewed, low-quality, or irrelevant generated code.
+- Do not mass-submit unrelated or low-quality AI-generated pull requests. We treat that behavior as spam and may close the pull requests, block the contributor, and report the GitHub account.
+
+## AI-Assisted Contributions
+
+All contributors must follow our [AI Policy](./AI_POLICY.md) when using AI tools to assist contributions.

 TanStack Query uses [Nx](https://nx.dev/) as its monorepo tool.
 To run tests in a local environment, you should use `nx` commands from the root directory.
 
+The `compile` target writes only its own package's `dist-ts` output. Nx compiles
+its dependencies first. TypeScript tests use `--project` to read these dependency
+declarations without rebuilding them. Each compiler version writes its own

+This lets type tests run in parallel without overwriting each other's output or
