Vibe coding: what it is, where it works and where it breaks.

What is vibe coding, really?

The idea is simple: you describe the result, run it, see what came out and ask for a tweak. You barely read the code. Instead of “write a function”, you say “I want a login screen with email and password” and talk it through until it is right.

It is not a formal method. It ranges from someone building a weekend prototype to someone shipping a product with agents and reviewing what matters. What they share is the inversion of the work: less typing, more asking and checking.

Where does vibe coding work well?

• Prototypes and internal tools. A spreadsheet that became a form, a dashboard for the team, a script that renames files.
• The start of a project. Folder structure, basic screens, sign-up, listings.
• Small, well-bounded tasks. “Add tax ID validation to this form” has a beginning, middle and end.
• Learning. Watching an agent build something and then reading the result teaches a lot.

Where does it break?

The failure points are the same for almost everyone.

• Vague requests. “Improve the app” produces changes you do not want and cannot undo.
• Code nobody read. When something breaks in production, or a security issue shows up, nobody understands what is in there.
• A project that grows. Without tests or organization, every new request breaks something old.
• Everything in the same directory. Several agents editing the same folders trample each other.
• No version control. Without git, there is no “go back to before”.

Most of this is solved with habit, not tooling: use git from day one, ask for one thing at a time, read the diff before accepting and keep a test command that tells you whether it still works.

How does Tactyn help with vibe coding across several agents?

When you go from one agent to two or three, problems appear that are not about code. Tactyn goes after those:

• You see all agents and projects in one place and get alerted when one stops waiting for an answer.
• The maestro turns a request into tasks, each in its own worktree and branch, so agents do not trample each other. You approve the plan and see the diff before merging (Mac only, for now).
• The meter shows how much of your subscription is left, so the afternoon does not run out mid-task (Mac only, for now).
• Dictation lets you speak the request instead of typing it (Mac only, for now).

What it does not do: it does not improve the code the agent writes, does not replace review and does not remove the need for git. The maestro requires a folder with a repository and at least one commit. It organizes the parallel work; quality still depends on what you ask for and what you review.

A simple flow to start

1. Create the project with git and make a first commit.
2. Describe a small goal and a way to prove it worked, such as a test command.
3. Let the agent work and read the diff, even if only quickly.
4. Only then ask for the next thing. If it is independent, use a second agent on another branch.
