Custom Review Prompt toggle

[m1rl0k]

I propose to add a custom review prompt with a toggle of on, in the users github action, allowing to seamlessly swap between default prompting and offering the user an additional prompt to modify, without effecting the core workings of presubmit, but to offer more granular reviewing for custom projects.

I have this done privately and seems to work well. I’ve also batched context and llm calls to also switch context based on the git diff, i.e. If security related changes made; perform in that context, if core code changes, perform in that context, if configuration changes perform in that context, or if two type of changes present, review with security + configuration, etc.

#53 although I think 3.5 model is now depreciated on run, I added AWS bedrock support, custom prompt with 3 dynamic mode options, documentation option, a full option for CLI, and context window batching (handles large context diffs better to the LLM may call it two or three times if a huge PR, with some diff magic in there... This is what we are using modified in an enterprise setup, thought I would share.
