This guide introduces Roo Code and the innovative Boomerang task concept, now integrated into SPARC Orchestration. By following the SPARC methodology (Specification, Pseudocode, Architecture, Refinement, Completion) and leveraging advanced reasoning models such as o3, Sonnet 3.7 Thinking, and DeepSeek, you can efficiently break down complex proj…

Thanks for the clinerules and roomodes files. Finding a lot of success using this over memory bank.

Tips on configuring this with memory bank? Also, how can you specify a specific model/mode per "slug"?

love this, thank you.

what are the best models for each slug, if i want to use only free models in openrouter ?

I believe if you use SPARC2, it will include a memory bank. https://github.com/agenticsorg/sparc2 (also developed by Rueven Cohen aka rUv)

@ruvnet yesterday, in the coding session; I had asked if each of the modes can be allocated a different LLM. You mentioned we can. Please clarify where in the .roomodes json file, we can can specify different LLM for each of the slugs and if the different API keys for different LLMs have to be specified too?

@mondweep you do this within Roo Code. Create custom profiles with your wanted model. Then assign the profile to the mode. This support was added in 3.12. See https://docs.roocode.com/features/api-configuration-profiles
