I don't understand why people criticize this post. When you run a homepage or a blog, it's unavoidable to write script style code. Even if the quality is a bit low, that's the limit within a tutorial. Because if you go into actual design, things like boundaries, policies, error handling, and so on require a lot of prior knowledge. So when certain knowledge is needed, you can only post something as a simple runnable script.
For example, if I were building real software, I would design everything from policy to error logging policies and so on. But when writing a blog post, it's just simplified into a short runnable script.
Code tutorial on medium (who's formatting is absolutely not meant for this)?
Please stop posting.
Jesus the terminology is so fucked… compare the contents of this blog post with any RL paper containing the words “long term planning”…

Yeah yeah... the world needs even more "aI aGenTz". This will help fighting climate change and child starvation.
Are people using medium in 2026?
I've tried most form of planning - from the basic AGENTS.md guide to keeping ./dev/ plan files, todo list tools, sqlite db with both minimal and extensive tracking, etc.
None of them have been worth it. A year ago the models needed to be reminded. Today they can follow a plan from text alone. This is my experience from working on a project alone - in teams ... i actually think the same lesson holds in the new AI paradigm.
My current scheme is basically this - in order of the task's complexity:
- Tell an agent to do something
- Tell an agent to make a plan then tell it to execute on it.
- Tell an agent to make a plan, write to a file, have a subagent review it, then execute it.
- Do the above, but instead tell the agent they're in a supervise mode and to have subagents implement as many phases and rollover with a handoff.md while they, as the supervisor agent, keeps driving the task to completion.
The latter two i have under a sigil so they're prepared prompts i can inject with a few keystrokes.
If i feel very fancy i'll tell them to update the plan with a checklist and add checkboxes, but it just doesn't pay enough to have 'init-prompt' level planning feature or tools if in the same context you already have files/read/write.
