# A macOS prompt refiner for coding agents

Source: https://refyneit.com/prompt-refiner

Turn rough coding requests into scoped instructions in Codex, Claude Code, Antigravity, OpenCode, T3 Code, or Cursor. See a worked example and what to review before sending.

## Start with the change you can describe

A useful coding prompt names the problem, the boundary, and a way to check the result. Refyne helps organize those details in the field where you already work. It is a native macOS app, currently in private preview.

Hold Fn + Control in a supported prompt field to refine your request. Review the replacement before submitting it to the coding agent. Terminal capture depends on an identified supported session and its bridge.

## Before: a request with enough facts to preserve

This authored example shows a refinement pattern. It is not a recorded model run or a performance result. Both versions contain the same task facts.

In our Next.js checkout form, pressing Enter on an empty email field submits the form. Require a valid email before submission, preserve the existing error styling, test keyboard submission, and run the web lint and type checks.

## After: a brief the agent can check

The structure separates the requested change from the limits and verification. It does not invent filenames, a root cause, or a promised outcome.

Goal
Prevent the Next.js checkout form from submitting until the email field contains a valid email.

Reproduction
Press Enter while the email field is empty. The form currently submits.

Constraint
Preserve the existing error styling.

Verification
Test keyboard submission with empty, invalid, and valid email input. Run the web lint and type checks. Report the change and check results.

## Give context without asking the refiner to guess

Name the affected behavior, a reproduction step, and anything the change must preserve. Attach a relevant file with a file tag or connect workspace context when the request depends on repository details.

Selected workspace context can supply real files and symbols. Review the included context and the refined prompt. Secret filtering helps reduce exposure, but it does not replace choosing what to share.

## Choose the depth of the rewrite

Auto adapts refinement depth to the task. Coding focuses on implementation instructions. One Shot expands a short request into a fuller brief. The target coding agent changes the instruction style, not the provider that performs refinement.

Refyne supports Codex, Claude Code, Antigravity, OpenCode, T3 Code, and Cursor. It refines the instruction; the target agent still performs the coding work.

## Choose a workflow that fits the task

Use a direct prompt when the request is already clear and short. A refiner is useful when you need to organize several known requirements, constraints, and checks before handing work to an agent. More words do not automatically make an instruction better.

A coding agent plans and edits the repository. Refyne prepares the instruction that you send to that agent. A reusable prompt template supplies a starting structure; it does not know your project's files or requirements. A speech-to-text app supplies a transcript; dictation alone does not refine the task.

The free browser coding brief builder is available now and organizes details you enter without an account or a model call. The Mac app adds AI refinement, capture from supported inputs, selected workspace context, and local dictation. The Mac app remains in private preview.

## Check privacy and availability before choosing it

Prompt refinement uses a cloud provider and requires an internet connection. Prompts and selected context leave your Mac for that operation. Local history and default on-device voice are separate from cloud refinement.

The private preview requires macOS 26 Tahoe or later and Apple Silicon. Public downloads and subscriptions are not open. Join the waitlist for access updates; the pricing page describes proposed plans.
