Create EF Core PRs targeting servicing release branches (release/*). Use when working on a PR that targets a release branch, backporting a fix from main, or when the user mentions servicing, patch, or release branch.

Implementation details for EF Core test infrastructure. Use when changing test fixtures, SQL baseline assertions, test helpers, the test class hierarchy, or when adding new tests.
Implementation details for the EF Core Azure Cosmos DB provider. Use when changing Cosmos-specific code.
Run ApiChief in the EF Core repo to emit baselines, summaries, deltas, review files, or breaking-change checks. Use when refreshing `*.baseline.json`, preparing API review artifacts, or validating API changes.
Create custom GitHub Copilot agents. Use when asked to create, scaffold, or configure a custom agent, declarative agent, or @-invokable chat participant for GitHub Copilot.
Create new Agent Skills for GitHub Copilot. Use when asked to create, scaffold, or add a skill. Generates SKILL.md with frontmatter, directory structure, and optional resources.
Implementation details for EF Core migrations. Use when changing MigrationsSqlGenerator, model diffing, migration operations, HistoryRepository, the Migrator or related classes.

PRs targeting release/* branches require a specific description format and should include a quirk (AppContext switch) when applicable. When updating progress on a servicing PR, ensure that the description still follows the template.
release/XX.0 (e.g., backport to 10 → release/10.0)release/XX.0 branch (ignore preview branches like release/11.0-preview2)[release/XX.0] <original PR title>
Fixes #{issue_number}
Backports #{source_pr_number_if_applicable}
**Description**
Provide information on the bug, why it occurs and how it was introduced. Put it in terms that developers can understand without knowledge of EF Core internals.
**Customer impact**
How the bug affects users without internal technical detail. Include a short (3-4 lines) code sample if possible. If data corruption occurs, state that explicitly. If a feasible workaround exists, briefly describe it and how discoverable it is, otherwise mention that there's no workaround.
**How found**
How the bug was discovered based on the information in the issue description. If user-reported, mention "User reported on <version>". If multiple users are affected, note that. Count the number of upvotes and comment authors to estimate impact.
**Regression**
Whether this is a regression from an earlier EF version. Add a link to the PR that introduced the regression if known. If it only affects a feature introduced in the same major version, it is not a regression.
**Testing**
State the number of new or modified tests, don't go into details. If test coverage is unfeasible, briefly explain the alternative validation approach that was used.
**Risk**
Brief risk assessment ranked from "extremely low" to "high". Note amount of code changed. If the fix is a one-liner, mention that. If a quirk was added, mention "Quirk added".
A quirk lets users opt out of the fix at runtime, reducing patch risk. Add for all cases where it makes sense. Skip when the fix is 100% obvious/risk-free, or when the quirk couldn't be used, like in tools or analyzers.
Add in the class(es) containing code changes:
private static readonly bool UseOldBehavior37585 =
AppContext.TryGetSwitch("Microsoft.EntityFrameworkCore.Issue37585", out var enabled) && enabled;
37585 to the relevant issue number!UseOldBehavior37585 so activating the switch bypasses the fix, prefer to minimize the number of times the switch is checked
