Capacities Skill

Understanding Capacities

Capacities is a graph-based PKM (Personal Knowledge Management) app — the user's "second brain".

Key concepts:

Space = A workspace (most users have one)
Structure = Object type (e.g. "Book", "Note", "Task", "Person"). Defines what properties objects of this type can have.
Object = User-created content. Has a type (structureId) and a title. Each object can fill in the properties defined by its structure.
Property = A field in a structure (e.g. "Author", "Rating", "Created at"). Every object of that type can have this property filled in.
Collection = User-created grouping within a structure type.

Example: Structure "Book" has properties [title, Author, Rating, Notes]. When user creates a Book object called "Erta Ale", they can fill in Author="Atticus", Rating=5, etc.

Commands

Run via:

python .claude/skills/capacities/capacities.py <command>

space-info — Understand the space

Returns all Structures (types) with their properties and collections. Run this first to understand what types exist.

space-info

Output format:

Book (id: uuid)
  Properties: title, Author, Rating, Notes, ...
  Collections: To Read, Favorites

search — Find Objects (user content)

Find actual content the user created.

search "query"                   # Search by title
search "query" --mode fullText   # Search in content too

daily-note — Save to today's journal

Quick capture. Good for insights, reminders, quick thoughts.

daily-note << 'EOF'
## Insight
Long content with "quotes" and special chars...
EOF

weblink — Save a URL

weblink "https://url" [--title ""] [--tags "a,b"] [--notes "markdown"]

create — Create new Object ⚠️ LOCAL ONLY

Requires Capacities desktop app installed. (Won't work in sandboxes, use MCP instead.)

create --title "Title" --content - [--type Book|Note|Task|...] << 'EOF'
Long markdown content with "quotes"...
EOF

current — Get what user is looking at ⚠️ LOCAL ONLY

Requires Capacities desktop app installed. (Won't work in sandboxes, use MCP instead.)

current

Returns title, URL, type, and content snippets of the active object — all in one call.
