You’ve been copying the same instructions into 20 different prompts. That was stupid. It stops now.
Fragments
Write your coding standards once, use them everywhere, update them once.
Any prompt can be a fragment. Reference it with {{>promptName}}. Migi swaps in the content when you run it.
Example:
Create a prompt called “API Standards”:
Return JSON format
Include error handling
Add rate limiting
Document response codes
Use it anywhere:
Build an API endpoint for {{feature}}.
{{>API Standards}}
No copying, no maintaining 15 versions, just reference it.
Autocomplete
Type {{ anywhere and autocomplete shows up instantly. All your prompts in blue, all your variables in purple. Monospaced font with folder names for context. Arrow keys to navigate, enter to insert. Fast enough to use while thinking.
Nesting
Fragments can reference other fragments. Nest them 10 levels deep if you want (you won’t).
{{>Company Context}}
{{>Coding Standards}}
{{>Testing Requirements}}
{{>Documentation Format}}
Now build {{feature}}.
Each piece is reusable and maintainable.
Path Resolution
Multiple prompts with the same name? Use paths like {{>Coding/Standards}} and {{>Design/Standards}}. Or just use the name - Migi prefers the one from the same folder and usually gets it right.
References Stay Valid
Rename a fragment? Migi updates every reference automatically.
Delete a fragment that’s in use? Migi shows you where and asks first.
Read the full fragments documentation for examples and patterns.
7x Faster Hotkey
First activation took 350ms. That was sluggish. Now it’s 50ms. Preload the window, keep it ready, show it instead of building it every time.
Editor Fixes
Mousewheel scrolling works. Selection and clicking behave like they should. Autocomplete cursor doesn’t jump to weird positions anymore when you type a space after inserting a variable. Clicking in the editor focuses it correctly.
These were all paper cuts.
Preferences
Don’t want the menu bar icon? Turn it off in General preferences.
Also Fixed
Windows remember their size. Tag filters are more compact. Play, Save, and Add Option buttons now have tooltips. Tabs close when you delete their prompt. Folders only show when they contain prompts. System alerts replaced with custom sheets.
System Requirements
- macOS 15.5 or later
