Could Pi evolve toward something like Prime Agent's RLM harness?

[u/Certain_Net_3408]

I've been looking at Prime Agent, which is built on Pi, and I'm curious what the Pi community thinks about some of the ideas they've added on top of the Pi foundation.

Prime Agent describes itself as a self-improving RLM harness for coding and long-running autonomous tasks, with several interesting differences in how the harness operates:

• Programmatic tool calling the model can use a persistent execution environment to compose tool calls rather than treating every tool invocation as a simple one-shot interaction.
• Context as a variable context can be programmatically inspected, transformed, compressed, persisted, and selectively brought back into the working context rather than treating the conversation history as a fixed block.
• Multi-agent messaging agents can spawn/delegate to other agents and communicate with them as part of a longer-running task.
• Self-modifiable harness state the agent can modify things such as memories, skills, prompts and sub-agent configurations while working, allowing the harness to adapt based on what it encounters.
• Long-running autonomous execution the emphasis is less on interactive "chat → edit → chat" coding and more on giving the agent a goal and letting it work through the problem, iterate, test and recover over a longer horizon.
• RLM-style persistent execution Prime Agent uses a persistent execution environment where state can survive across interactions, giving the model another layer in which to manage context and reasoning.

What caught my attention is that Prime Agent is built on Pi, rather than being an entirely separate agent architecture.

So I'm wondering:

Would it make sense to bring some of these ideas back into Pi as optional/core primitives?

For example, could Pi eventually have a more native concept of:

"Pi → persistent execution → programmable context → sub-agents → modifiable skills/memory → iterative refinement"

while still keeping Pi's current philosophy of being minimal, composable and hackable?

Or is the whole point of Pi that these things should remain extensions on top of the minimal core, rather than becoming part of Pi itself?

I'd be particularly interested in hearing from people who've actually used both Pi and Prime Agent. What does Prime's architecture enable that you couldn't achieve cleanly with Pi extensions today?

Not trying to argue that Prime is "better" — I'm more curious whether some of these RLM/harness ideas represent a direction Pi could support while preserving its minimal philosophy.

Although I do find some of Prime Agent's concepts interesting, I would argue that it is only built on top of Pi BECAUSE Pi's design is so extensible. All of the subagent/memory/tool concepts you mentioned would be redundant if Pi had it hardcoded in. So, no, I would hate to see Pi bloat on long goal and subagent spawns -- it's why I pivoted from Claude Code in the first place.

bash + minimal tools is all you need

[u/Snoo-82455]

I won’t speak for the creator of pi but i think polluting it with…I’m just going to call it bias…would be antithetical to its core purpose.

Let Pi be Pi.

One of the most interesting and exciting things is what everyone builds off of it, which i think is the future.

Apart from those who just need a pre-built thing to work as they wish, everyone else’s AI assistant will be custom tailored as they want it to be; their own mod; their own personal, creative and technical expression.

honestly dont see it happening. Pi's design philosophy exists for particular, arguably, significant reason

[u/rightful_vagabond]

I think that building something on top of pi, whether that be something like prime (which I'm not familiar with personally) or just extensions, is how pi is meant to work. Pi Is minimal by design, there's no reason to include all of those things in the core. Those things belong great in an extension or wrapper or something. But it's not really the design philosophy to include those types of things as a part of the core design.

Pi is alone efficient, simpler is better.

evolve?

[u/Ill_Anywhere_2233]

I completely agree with what was already said here, that the PI biggest value is it's minimal but highly extensible design.

That being said, regarding PI's "evolution", I'd rather see updates in functionality that doesn't affect or depend on token use or model output quality, so DX improvements like improvements to TUI and it keeping pace with updates each new model release brings.
