// OVERVIEW

A Skill is a small, focused behavior — a way of responding, a tone, a constraint. Tutor Mode is a Skill. Concise is a Skill. Humanizer is a Skill. The interesting part is stacking: turn on three at once and J@rv1s doesn't sequence them, it blends them into a single coherent voice.

Three skills, one blended response. Not a pipeline — a weighted personality.

// KEY FEATURES
Composable

Skills don't fight each other. The planner negotiates conflicts before the response is written.

Toggleable

Tap a skill to turn it on or off mid-conversation. The next reply respects the new stack.

Saveable

Pin a stack to a Project. Open the project, the stack comes with it.

Custom (Pro)

Write your own skill in plain English. J@rv1s compiles it into a behavior the planner can use.

Drop a skill the moment it stops helping. Add a new one.

// WHO USES IT
Studying
Tutor + Concise + Humanizer → step-by-step, short, sounds like you wrote it.
Coding
Engineer + Pedantic + Concise → terse code, exhaustive edge cases, no fluff.
Writing
Drafter + Humanizer + Editorial → first draft in your voice with publication-grade structure.
// QUESTIONS
Can I disable all skills?

Yes. With zero skills active, J@rv1s defaults to its standard reasoning behavior.

Do skills change the model?

No. Skills shape how the same model thinks and responds — they don't swap out the underlying reasoning engine.
