The first test MRs (#224) included "Streamlined module declarations and imports for better maintainability" in its summary of the changes, which isn't particularly useful.

I added "Dont mention changes to the import statements" to its custom instructions, and the summary for the second test MR (#225), containing the same changes, was much better: "Implemented a state machine for the CEK interpreter". But its review comments didn't do anything to help me understand the new CEK interpreter, they only complained about the lack of error-handling, which is not very useful either since the Expand monad is already propagating errors automatically.

Let's see what CodeRabbit emits with the following instructions:

Dont mention changes to the import statements nor to the language extensions at the top of the file.

Don't point out missing error-handling code, the type-checker already detects those mistakes at compile-time.

Do explain what the new code does and how changes to existing functions affect their behavior.

Walkthrough

## Walkthrough The Haskell project has undergone a significant refactoring, focusing on enhancing the exception handling and evaluation logic within its REPL. The changes streamline the evaluation process by implementing a CEK interpreter's state machine and adjusting how closures and values are handled. The refactoring also includes code simplifications, the introduction of new language extensions, and an update to the error handling strategy. ## Changes | Files | Change Summary | |----------------------|----------------------------------------------------------------------------------------------------| | `repl/Main.hs` | Refactored exception handling and evaluation logic, removed `evaluate` import. | | `src/Evaluator.hs` | Added CEK interpreter components, new data types, refactored `eval` to `evaluate`. | | `src/Expander.hs`, `src/Expander/Monad.hs` | Added import, removed redundant `eval` calls, updated error handling and value evaluation logic. | ## Poem > 🐇💻 CodeRabbit hopped through the code, > Refactoring with a poet's ode. > Bugs in the fields, no longer free, > Caught in the snare of GPT. 🌟

Tips

### Chat There are 3 ways to chat with CodeRabbit: > Note: Auto-reply has been disabled for this repository by the repository owner. The CodeRabbit bot will not respond to your comments unless it is explicitly tagged. - Files and specific lines of code (under the "Files changed" tab): Tag `@coderabbitai` in a new review comment at the desired location with your query. Examples: - `@coderabbitai generate unit tests for this file.` - `@coderabbitai modularize this function.` - PR comments: Tag `@coderabbitai` in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples: - `@coderabbitai generate interesting stats about this repository from git and render them as a table.` - `@coderabbitai show all the console.log statements in this repository.` - `@coderabbitai read src/utils.ts and generate unit tests.` - `@coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.` Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments. ### CodeRabbit Commands (invoked as PR comments) - `@coderabbitai pause` to pause the reviews on a PR. - `@coderabbitai resume` to resume the paused reviews. - `@coderabbitai review` to trigger a review. This is useful when automatic reviews are disabled for the repository. - `@coderabbitai resolve` resolve all the CodeRabbit review comments. - `@coderabbitai help` to get help. Additionally, you can add `@coderabbitai ignore` anywhere in the PR description to prevent this PR from being reviewed. ### CodeRabbit Configration File (`.coderabbit.yaml`) - You can programmatically configure CodeRabbit by adding a `.coderabbit.yaml` file to the root of your repository. - The JSON schema for the configuration file is available [here](https://coderabbit.ai/integrations/coderabbit-overrides.v2.json). - If your editor has YAML language server enabled, you can add the path at the top of this file to enable auto-completion and validation: `# yaml-language-server: $schema=https://coderabbit.ai/integrations/coderabbit-overrides.v2.json` ### CodeRabbit Discord Community Join our [Discord Community](https://discord.com/invite/GsXnASn26c) to get help, request features, and share feedback.

Dont mention changes to the import statements nor to the language extensions at the top of the file.

Don't point out missing error-handling code, the type-checker already detects those mistakes at compile-time.

Do explain what the new code does and how changes to existing functions affect their behavior.

Well, CodeRabbit still mentioned "Added import" and "the introduction of new language extensions". It did not explain what the new code does, I guess that's not what CodeRabbit is designed to do.

CodeRabbit still spuriously complains about error-handling, but only once, which is a big improvement over the second test MR (https://github.com/gelisam/klister/pull/225), which did this 9 times!

Expanding the "Additional comments: 25" blocks shows "[...] Since the PR instructions specify not to mention error handling, this change is assumed to be intentional and correct". It is reassuring to see that the AI did take my instructions into account!
