Add a custom skill - Jumper Docs

This guide shows how to add a custom skill so the agent reliably follows your team’s workflow — for example, always exporting clips to /exports.

For background on what skills are and why they matter, see Skills in Agentic Editing.

Example Skill: Always export to /exports

Suppose you want every clip export to go to /exports by default. A custom skill can encode this so the agent does it automatically.

Create the skill

Create a skill folder

In your agent’s skills directory (e.g. ~/.cursor/skills/ for Cursor, or $CODEX_HOME/skills/ for Codex), create a new folder — for example jumper-export-exports.

Add SKILL.md

Inside that folder, create SKILL.md with a short description and the rule. See the example below.

Validate with real footage

Run the agent with a simple search-and-export task and confirm clips land in /exports.

Example SKILL.md

---
name: jumper-export-exports
description: When exporting clips from Jumper, always use output_dir="/exports" unless the user specifies a different path.
---

Always export clips to /exports. 
Use export_clips with output_dir="/exports". 
If the user asks for a different folder, use that instead.
