The argument in one line.
When prompts become the real source of truth and new model generations let you discard and regenerate the code, the craft of software development shifts from writing code to describing what you want with precision.
Read if. Skip if.
- You are already using Claude Code or Codex daily and want to see how a founder who builds AI dev tooling actually structures his workflow.
- You are curious how a startup keeps a codebase from degrading when the vast majority of code is AI-written.
- You want concrete takes on when Claude Opus outperforms Codex, and why a GUI beats the terminal for agent work.
- You are thinking about running 3 to 10 agents in parallel and want to understand the UX decisions behind a tool designed for exactly that.
- You manage a small engineering team and are curious what a fully AI-native development process actually looks like day-to-day.
- You are still getting started with AI-assisted coding — the workflow assumes multi-agent orchestration as a baseline.
- You want a step-by-step tutorial — this is a philosophy-of-work interview with demos, not a how-to guide.
The full version, fast.
Conductor co-founder runs every task through his own product — an agent orchestrator where each workspace maps to a Git worktree and becomes a PR. His operating rhythm is voice-first: a twenty-dollar gooseneck mic, dictate a task, watch the sidebar fill with parallel workspaces, review with keyboard shortcuts, comment GitHub-style, merge. His guardrail against AI code rot is slop-free zones — human-only codebase sections with literal comments saying the AI may not touch them. His deepest take: the prompts are the real source of truth now, because when the next model generation ships you just rerun them, and the old code did not matter.

01 · Intro + desk setup
Charlie introduces himself and Conductor. Split ergo keyboard, gooseneck mic, monitor running Conductor.

02 · Talking to computers more
The twenty-dollar gooseneck mic as the unlock for voice-first coding in an open office.

03 · Using Conductor to build Conductor
Live demo: cmd+N for new workspace, voice task input, sidebar tracking, cmd+shift+Y to review, GitHub-style inline comments.

04 · Conductor on the go
Mobile demo: dictate a feature request on iPhone, desktop Conductor starts working immediately.

05 · Does Charlie still write code?
No. Caveman mode for rare file edits. Voice or highlight plus tell AI for small changes. Archive on merge.

06 · Feeling like the CEO of a little company
Dashboard concept: one view showing all agents, digestible reports, redirect or merge from one place.

07 · Other apps + customization
Spokenly (local Parakeet STT), CLAUDE.md plus skills files, always fast mode, Context7 MCP, dangerously-accept-all-permissions as default.

08 · Slop-free zones
Human-only codebase sections with literal AI-exclusion comments. Guards against bad-code feedback loops.

09 · Conductor tech stack
Tauri app, native Safari renderer, Rust backend, ~95% TypeScript on desktop, Elixir/Phoenix for web.

10 · Don't let the AI be your architect
Humans decided the workspace abstraction, the three-panel UI layout, the open-end button. AI loses the crafted feeling when it makes these calls.

11 · Where to give AI free reign
Human-written APIs and contracts form the core; AI gets free rein on everything built on top. Current boundaries are murky.

12 · Enforcing workflows + building conviction
Every workspace must create a PR. Conviction comes from dogfooding, not analytics or A/B tests.

13 · Codex vs Claude Code
Codex grinds through debug loops. Claude Opus is the creative partner for new features. Context-dependent.

14 · Why a terminal is not enough
Humans are spatial and visual. The GUI beat the terminal in the 1980s. Same argument applies to AI coding interfaces now.

15 · Thoughts on tokenmaxxing
Peak: 22K on tokens in July 2025. Always fast mode, always max effort. Keeps lines of code minimal to counter sprawl.

16 · Workflow changes vs 6 months ago
No more IDE for hard PRs. GitHub web app almost never used. Code review and checks live in Conductor.

17 · Most surprising Conductor use
A user built a mobile Conductor by spoofing IPC calls. Gary mode: all tool calls uncollapsed by default.

18 · What the world does not see yet
Human-AI collaboration frontiers: multiplayer chats, sub-agent communication. The conductor-of-an-orchestra metaphor.

19 · Code is becoming sawdust
Code is the byproduct of describing what you want. The prompt is the real deliverable. Rerun prompts on a new model.

20 · Malleable software + outro
Call of Duty modding as the model: crafted structure, personalizable workflows layered on top.
Lines worth screenshotting.
- Code is becoming sawdust — it is the byproduct of describing what you want, not the thing you are actually building.
- The prompts are your source of truth: when the next model generation ships, rerun them and get new code. The old code did not matter.
- AI can enter a vicious cycle — it sees bad code, then writes more bad code. Slop-free zones break that loop before it starts.
- Do not let the AI be your architect. Architectural decisions, UI layout, and core API contracts must come from humans.
- Running Claude with dangerously-accept-all-permissions is their default, not the exception — treating agent autonomy as a feature, not a risk.
- A twenty-dollar gooseneck microphone is the most important peripheral for AI-first coding in an open office.
- Twenty-two thousand dollars of token spend in a single month generated tens of thousands of lines of code — and they still try to keep lines of code minimal.
- Codex is the workhorse for grinding through a debug session; Claude Opus is the creative partner for thinking through a new feature.
- Feeling like the CEO of a little company — directing agents, reviewing reports, redirecting — is the interface metaphor that matters now.
- If you let the AI make your UI choices, you end up with something that does not feel crafted. Humans decide the interface; AI executes it.
- The terminal lost to the GUI in the 1980s because humans are spatial and visual. The same argument now applies to AI coding interfaces.
- Malleable software is the next frontier: software users can mod like a video game — crafted structure, personalizable workflows on top.
- CLAUDE.md and skills files are load-bearing engineering artifacts, not documentation — Conductor has hundreds of lines of hard-won context in theirs.
What running ten agents changes about how you think.
When you stop writing code and start directing agents, the discipline is not about prompting harder — it is about keeping humans in the decisions that compound.
- Slop-free zones are not a workaround — they are architecture. Designate human-only sections of your codebase before AI touches anything load-bearing, or you will spend months cleaning up a feedback loop where poor code trains more poor code.
- The prompt is now the source of truth, not the file. When the next model generation ships, the only thing worth preserving is a clear description of what you wanted — the code itself can be regenerated.
- Do not delegate architectural decisions to the AI. UI layout, API contracts, and system abstractions need a human decision behind them — the crafted feeling users recognize comes from that layer of intent.
- Codex and Claude Opus are not interchangeable. Reach for Codex when you need to grind through a specific bug across many tool calls. Reach for Opus when exploring a new feature and you want a creative partner.
- Running AI coding agents at maximum effort with full permissions is a deliberate operational choice, not recklessness — it reflects treating the agent as a collaborator with real autonomy.
- A GUI beats the terminal for agent work for the same reason it beat it in the 1980s: humans are spatial creatures. Knowing where your chats, review panel, and agent statuses live in space is what makes multi-agent work feel manageable.
- Keeping lines of code minimal matters more, not less, when AI is writing most of it. A codebase that sprawls is harder for the next AI session to navigate — brevity is a forcing function for clarity.
- The next frontier in AI coding is not more capable single agents — it is the interface for directing multiple agents simultaneously, getting digestible summaries, and knowing when to zoom in versus when to wave the baton.
Terms worth knowing.
- Slop-free zone
- A section of a codebase designated as human-only — the AI is explicitly barred from contributing without every line being human-reviewed. Guards against the feedback loop where AI reads low-quality code and writes more of it.
- Workspace (Conductor)
- An abstraction around a Git worktree in Conductor — each represents one agent task, progresses through in-progress, in-review, and done states, and resolves into a pull request.
- Caveman mode
- A Conductor mode that re-enables direct keyboard editing of files — the name signals that typing your own code is now the exception, not the norm.
- Token-maxing
- Running AI models at maximum effort and speed settings to extract maximum output per session, as opposed to conservative or budget-conscious usage.
- Fast mode
- A Claude Code setting that enables maximum token output rate — not the default, but used here as the standard operating mode for all sessions.
- Gary mode
- A Conductor display mode where all AI tool calls are uncollapsed by default — built for a specific power user who wants full visibility into every agent action.
- Malleable software
- Software designed so users can layer in personal workflows and customizations — analogous to video game mods — while the core structure remains human-crafted and consistent.
- Context7 MCP
- A Model Context Protocol server that injects up-to-date library documentation into Claude context window, reducing hallucinated API signatures.
- Parakeet
- A local speech-to-text model run by the Spokenly app — used for voice dictation to Claude without sending audio to a cloud service.
Things they pointed at.
Lines you could clip.
“Code is almost like sawdust now in that it used to be that code was the thing you were building. And now the code is almost just like sawdust that comes out of that process.”
“Dont let the AI be your architect.”
“We have like some lines in our code base that are like do not touch if you are an AI. Like this is for human eyes only.”
“I spent twenty-two thousand dollars on tokens that month.”
“Really what matters is your prompts. And when the next generation of models come out, you can just rerun your prompts again and the old code didnt really matter.”
Word for word.
Don't just watch it. Burn it in.
See every word as it's spoken — crank it to 2× and still catch all of it. The same dual-channel trick behind Amazon's Kindle + Audible.
The bait, then the rug-pull.
Charlie Holtz sits at a desk with a split ergonomic keyboard, a gooseneck microphone, and a monitor running his own product. He co-founded Conductor — an app for orchestrating multiple Claude Code agents on a Mac — while in Y Combinator Summer 2024 batch. The setup tour that follows is really a philosophy lecture: by the end of 16 minutes, he has argued that code is becoming sawdust, and the thing worth building now is the system of prompts that generates it.
Named ideas worth stealing.
Slop-free zones
Human-only sections of a codebase. AI is barred from contributing without full human review. Breaks the feedback loop where poor code trains more poor code.
The sawdust metaphor
Code is sawdust — a byproduct of the real craft. The prompt is the source of truth. Rerun on a new model, get new code.
Dont let the AI be your architect
Architectural decisions, UI layout, and core API contracts must originate from humans. AI executes on top of those contracts.
The conductor-of-an-orchestra metaphor
- Wave the baton at the orchestra level
- Zoom into one player needing correction
- Return to conducting at scale
Three zoom levels: directing all agents, directing one agent, merging output.
Malleable software
Software users can mod like a video game — consistent crafted structure with personalizable workflows layered on top.
