For the marketing job no workflow covers
When you ask Tin to inspect, research or change project files and no narrower workflow fits, it runs an isolated task with its own transcript and controls.

A Tin workflow is a repeatable job: declared inputs, a bounded run and a defined output. The steps below are what this one does, every time.
- 01Takes a title and an instruction.
- 02Runs in an isolated session against project files.
- 03Keeps its own transcript, so you can see exactly what it did.
Ask Tin to draft a reseller pricing tier from yesterday's customer email.
What every workflow here comes with
Battle tested on real products
These are the workflows we run for real companies. Claw Messenger went from about $45 to $2,105 in monthly revenue in 124 days on them. Each one has declared inputs, bounded execution and tests, and anything public waits for your review.
See the case study →Open source: read it, fork it, self-host it
Apache 2.0. Every workflow is a folder in the repository: the steps it runs, the data it reads and what it is allowed to do. Change it, or run the whole system on your own machine.
Open the repo →Runs on the agent that already knows your product
Your agent decides when a job deserves a workflow and when a one-off task is enough.
All workflows →Using something else for this today?
What this workflow replaces in each product, and what it does not.

Questions
Has this been useful in practice?
In the Claw Messenger project it produced a reseller tier the day after a customer asked for one.
Is Tin really open source?
Yes. Tin is licensed under Apache 2.0 and the source is at github.com/tin-computer/tin. You can read every workflow, change it, and self-host the whole system.
Which coding agents can run Tin workflows?
Any agent that speaks MCP, including Claude Code, Codex and Cursor. There is also an API, and the same projects run in the browser at app.tin.computer.
Why run marketing from a coding agent?
Because it already knows your product. It has the repository open, so it fills workflow inputs accurately, reviews output against what the product really does, and can act on the results in the same session.
