Skills

Skills are one of Sentinel's extension systems.

They let the app pull in extra capability packs without stuffing every specialized workflow into the core app.

What skills can target

The skills UI supports three install targets:

• sentinel
• claude
• codex

That matters because a skill can live in different directories depending on the target runtime.

Scope

For local Sentinel and Claude skills, installs can be:

• global
• workspace-scoped

Codex skills are global only.

Sources

Skills can come from:

• the curated registry
• a custom repository or path

The app keeps track of what is installed and where.

What you can do from the skills screen

• browse installed skills
• browse curated registry entries
• inspect skill details
• install a curated skill
• install a custom skill
• uninstall a skill

For Codex-targeted skills, the app also syncs enabled state through the Codex app server manager.

Why skills exist

Skills are the simpler way to add focused behavior without growing the main app every time.
