Global/Mode system prompts

[bertvanbrakel]

It seems Roo currently supports workspace level system system prompt override.

The issue is that I use multiple workspaces to organise various projects, and having to replicate and manage system.prompts across them will be a pain.

Also, I'd like to be able to select a different system prompt per mode. This could help for example to reduce the amount of things sent to an LLM when I know that isn't required.

One approach is to look in order for the following files

HOME/.roo/system-prompt.{mode}.{model}.txt
HOME/.roo/system-prompt.{mode}.txt
HOME/.roo/system-prompt

In addition, maybe a template approach would be handy, so that we don't need to copy/paste and manage all the snippets.

E.g

Blah blah system prompt
{{builtin/mcp-tools}}
{{custom/mcp-my-custom-tool}}
etc

That makes it easier to chop and change things.

Just be a simple file based structure, with a simple text processor to merge the files into a single prompt.

It would be event cooler if we could include prompts dynamically based on the tasks at hand..Coding task? Add the coding prompts. Maybe the llm can call a tool called 'context-tags' to add or based on task, and behind the scenes this then adds/removes system prompts. Dependent inclusion could be done via a 'key?:

E.g'

{{bash?:custom/rules-bash.md}}

But this is getting more complex, and the simpler basic includes would be a good starting point.

If this is something that is desirable, I am willing to implement this time constraints allowing. Have to grok the codebase a bit first.
