Custom skills & subagents — extend your team's shared library

Team PM OS ships with over 70 skills and 6 subagents out of the box — you can add your own on top of them.

When to use this

You have a skill or subagent from another source that your team should share
An existing mySecond skill needs enough changes to warrant its own version
You want to build a new skill for a workflow specific to your team

Setup

In mySecond, click + Add from the Skills view. A dropdown gives you three options:

Customize a mySecond skill

Select Customize a mySecond skill from the + Add dropdown.
Choose the skill or subagent you want to start from.
Edit the file to fit your team's needs (see customizing skills for guidance on editing).
Save — your version appears in your team's shared library.

Import a skill file

Select Import a skill file from the + Add dropdown.
Upload the SKILL.md file.
The skill is added to your team's shared library and syncs to Claude Code for all team members.

New skill via Claude Code

Select New skill via Claude Code from the + Add dropdown.
Work with Claude Code to write a new SKILL.md file in your codebase.
mySecond detects the new file and syncs it to your team's shared library automatically.

How it works

All three methods result in the same thing: a skill or subagent that lives in your team's shared library and is available to every team member in Claude Code.

Custom subagents work identically — the same + Add dropdown and three options apply.

Skills and subagents you add this way are owned by your team. They don't receive automatic updates from mysecond.ai, and only team admins can edit or remove them from the shared library.
