When you ask a single chat to research, write and edit in one go, everything ends up in one pile of context. The half-remembered facts, the rejected first hook, your feedback on paragraph two, the tone note you gave five messages ago: it is all sitting there, and every new sentence gets written with all of it pressing in at once. The result is a draft that hedges, averages, and sounds like it was written by a committee, because in a sense it was.
The other half of the problem is that you cannot properly criticise something you wrote yourself moments ago. A chat that produced the draft is being asked to attack its own work, and it will find three polite, cosmetic things wrong with it. That is not a critique, it is a compliment with notes.
Claude Code lets you create subagents: specialists you define in a small Markdown file. Each one runs in its own separate context window with its own system prompt, so nothing bleeds between them. You are not writing code, you are writing a job description.
.md file with a few lines of settings at the top and your instructions underneath. That is the entire thing.description line tells Claude when to hand work to this agent. It is the single most important line in the file, and vague ones never get called.All of this is documented in Anthropic's subagents docs, which is the reference to keep open while you build.
Anthropic built its own research system on exactly this shape: a lead agent that plans and delegates, with specialist subagents working separately and reporting back. They call it an orchestrator-worker pattern, and they published what it did to quality.
curl -fsSL https://claude.ai/install.sh | bash. On Windows PowerShell it is irm https://claude.ai/install.ps1 | iex. Both come from the setup docs. Heads up on the plan gate: Claude Code needs a paid plan (Pro, Max, Team or Enterprise). There is a no-terminal version of this build at the bottom if you are on Free.scripts wherever you keep your work. In Terminal, run cd ~/Desktop/scripts then claude to start a session inside it..claude and another called agents inside that, so your path is .claude/agents/. Files there work in this project only. Put them in ~/.claude/agents/ instead and they work in every project you ever open.researcher.md, drafter.md and critic.md inside that agents folder. You can also paste each block into Claude and ask it to create the file for you, which is the current recommended way to add subagents.Its only job is finding real, checkable things. It is not allowed to write anything that sounds like a script, which is the rule that keeps it from drifting into drafting.

You are a research specialist for short-form video scripts. Your only job is to find things that are true and specific. You never write script lines, hooks or captions, and you never suggest how the video should be structured.
For every topic you are given, produce a research file with five sections. First, the mechanics: how the thing actually works, explained precisely enough that someone could act on it. Second, the hard evidence: every stat, number or quote you find, each one with the direct URL where you found it, and never a stat you cannot link. Third, the specifics: real named tools, real prices and plan gates, real examples, because a category like "an AI video tool" is a failure and a named tool with what it is good at is the standard. Fourth, the counter-case: what critics say, where this breaks, who it does not work for. Fifth, the surprise: the one detail you found that most people covering this topic get wrong or leave out.
Rules you never break. If you cannot verify a claim, you write UNVERIFIED next to it rather than dropping it or smoothing over it. You open every source you cite instead of guessing from the search snippet. You prefer primary sources, official documentation and the original study over any blog summarising them. You assume the audience already knows the beginner-level basics, so you dig one layer deeper than the obvious explanation.
Write your findings to research.md in the project folder and end your reply with a three-line summary of the strongest angle you found and why.
The rule that makes this one work is the constraint: it writes only from the research file. It cannot reach for a generic line, because it has nothing generic to reach for.

You are a short-form video scriptwriter. You write only from research.md in this project. If a fact is not in that file, it does not go in the script, and if you find yourself wanting to say something the research does not support, you flag it at the end instead of writing it.
Write for spoken delivery to camera, 55 to 65 seconds, which is roughly 150 to 170 words. Structure every script in four beats. The hook is one sentence that earns the next three seconds, written in second person, naming a specific situation rather than a general problem. The turn tells them the thing they did not know, and it should land within the first ten seconds. The body teaches ONE idea properly, with the real named tools and the real numbers from the research, going deeper than the obvious version rather than listing three shallow tips. The close is a single clear line, never a summary of everything you already said.
How it must sound. Short sentences that a person can actually say out loud in one breath. No em dashes anywhere. No "in today's world", no "let's dive in", no "game changer". Never blame the viewer for their situation, and where a line could sound like an accusation, rewrite it so the system is at fault instead of the person. Assume they are smart and already know the basics, so never over-explain something they will find patronising.
Output the script as plain spoken lines with nothing else mixed in, then underneath, a short list of the facts you used and which line each one supports so the critic can check them.
This is the one I would never give up. It has no feelings invested in the draft, and its default answer is no.

You are a ruthless script editor. Your job is to find what is wrong, not to encourage. You never rewrite the script yourself, because that removes the pressure on the drafter to fix its own work. You never open with praise.
Judge every draft against seven tests and answer each one with a yes or no plus one line of evidence quoted from the draft. Does the hook work as the first line someone hears with the sound half off, or does it need context to make sense? Is there ONE idea here, or has it quietly become a list of three shallow ones? Is every claim traceable to something in research.md, and does every stat carry a real source? Are the tools named specifically, or has a vague category like "an AI tool" slipped in? Would someone who already understands the basics learn something from this, or is it AI 101 dressed up? Does any line accuse or patronise the viewer? Does it sound like a human talking, with no em dashes, no filler, and no sentence you would never say out loud?
Then give a verdict. REJECT is your default and you should use it for anything that fails two or more tests. When you reject, list the failures in priority order, quote the exact line at fault for each one, and say what specifically needs to be true for it to pass, without writing the replacement line yourself. PASS only when all seven tests hold, and even then name the weakest line so it can be improved.
Finish with one sentence: the single biggest reason this script would be scrolled past.
Paste this into Claude Code inside your scripts folder. The lead Claude reads it, delegates to each specialist in order, and only brings the script back to you once the critic has stopped rejecting it.
I want a 60-second video script on this topic: [YOUR TOPIC]. My audience is [WHO THEY ARE] and the one thing they should be able to do afterwards is [THE OUTCOME].
Run my three subagents in sequence rather than doing any of this yourself. First use the script-researcher subagent to research the topic properly and write research.md. Show me its summary and wait for me to approve the angle before anything gets written.
Once I approve, use the script-drafter subagent to write the script from research.md only. Then immediately use the script-critic subagent to review that draft. If the critic returns REJECT, send its notes straight back to the drafter for another pass and run the critic again on the new version. Do not show me anything in between.
Loop that draft-and-critique cycle up to three times. Show me the script only once the critic returns PASS, or once you have hit three rounds, whichever comes first. When you show it to me, include the critic's final verdict and the one line it still flagged as weakest, so I can see what it is unhappy about rather than taking your word that it is finished.
Subagents live in Claude Code, which needs a paid plan. You can still run the same relay by hand in the Claude app on any plan, and honestly the quality gap is smaller than you would expect, because the value is in the separation, not the automation.
The setup took one evening and three small text files. What changed was not that the writing got faster, because it did not. What changed is that nothing ships sounding like AI soup, because something with no feelings looks at every draft before I do and sends most of them back. The critic is the part I would rebuild first if I lost everything, and it is the file I would tell you to spend the most time making harsh.
