- dnlgrmmSadly this seems like introducing a very complex apparatus for little gain. I don't need MCP or many tool calls that the agent can program around - in fact the promise of pi was that you basically just need bash and no other tools. The minimally-invasive approach would have been to just "inject" tool calls as virtual bash commands. No code mode required, no hands vs. brains dichotomy. LLM can use language of its own choosing to interact with tools.
- ssivarkBetween this and the Cloudflare post, this is a lot of words and no simple system level picture. Here's what I think is going on:1. Homoiconicity: Harness mechanics are kludgy and we need proper homoiconicity to uniformly handle code (tool calls) and data ("natural language") as token streams.2. Actor semantics: for isolation, encapsulation and concurrency.3. Object capabilities: injected references and no ambient authority. Capabality-based reflection/introspection is a clean way to discover interfaces and affordances."Code mode" or whatever is basically rediscovering this by hacking outward from LLM token streams, instead of from system design principles based on decades of computer science. It is the beginning of treating an LLM as a programming-language runtime participant (any takers for eval/apply?) rather than as a text/token generator with the harness as an ad-hoc interpreter.If existing implementations of code mode don't already support all this, I anticipate they will keep piling on hacks till they get to this point.----I think it was Dan Ingalls who said "An operating system is a collection of things that don't fit into a language. There shouldn't be one.". I see the same for harnesses -- they're awkward middle children which fit neither in an LLM nor in the programming environment.Maybe the answer is to partner LLMs with Common Lisp or Scheme fibers / Spritely Goblins or Erlang BEAM and be done!
- freakynitCan someone please tell me how to disable it permanently in pi? I have already disabled it in settings.json, but, it just doesn't get disabled: { "source": "npm:pi-mcp-adapter", "extensions": [ "-index.ts", "-builtin:codemode" ] } and "autoEnableCodemode": false,
- mi_lkWhy is this a personal blog, not a Pi post?https://earendil.com/posts/you-said-no-mcp/ remains difficult to read without understanding what codemode is, with some quote like "Now we talked so much about Codemode, it might be worth explaining what that even is."
- ylxdzswI'm not sure why almost all codemode implementations choose Javascript. I prototyped an agent[1] to use bash as the language for codemode, which in my opinion worked equally well and requires no teaching (there is literally 0 prompt to teach the LLM about codemode. A tool named "bash" is enough to have them know the usage).[1] https://github.com/ylxdzsw/mu
- lemonthemeI’m still figuring out codemode. I was using it in a prototype, but ended up stripping it out again, after realizing my small local LLM was using more tokens than usual. It was combining tool calls elegantly in code exactly how I hoped it would. The problem was that when any of those embedded tool calls failed (e.g. on parameter validation) the parent code execution tool call also failed. In response, the LLM kept rewriting large parts of the original code block.Btw, Monty by the pydantic team is a joy to work with if you need a way to securely run unverified code. It’s a simplified Python dialect. You can also use it from JS, iirc.
- Starlevel004I've noticed that code mode seems to cause progressive lobotomisation in Sol 6.1 around subagents. The more it uses it, the worse it gets at giving prompts to subagents: URLs, datasourceproxy accesspathonlyallowed anddefault404. Do not set authbasic onprivate ports; perplanPodmannetwork trustedinfrastructure nottenant boundary. Publicroutes internal /tinyauth protected internal, proxyGETemptybody /api/auth/nginx toprivate tinyauth3000; proxy_pass_request_headersoff, CookieonlyTinyauthSession header extracted map name/value actual runtime pattern tinyauth-session-[0-9a-f]{8}, X-Original-URL constructed This is unedited; it's merging words together and spamming keywords.
- injidupHow is this different to Claude writing mini scripts to get jobs done which it does quite often?
- soltanovRecovery after interrupted execution; distinguishing completed side effects from calls that can safely repeat.
- aidiveytsubagents differ: in my claude code logs every subagent cache write is 5-minute tier, main session 1-hour
- troupoSo... What exactly is it in the end? I try to parse the long prose, and couldn't.It doesn't help that the article is titled "What is Codemode" and then goes to say "If you are not familiar with Codemode, it’s basically just...". You article is supposed to say what it is without anyone being familiar with it.Like what does this passage even mean:--- start quote ---For instance if you issue a bash call as a regular tool call in the LLM, then we only throw the trailing 2000 lines into the context and if the agent wants more, it needs to look at the overflow file itself. If however the agent issues that invocation via Codemode, then the Codemode side gets larger outputs sent structurally.--- end quote ---
