# Capsule Skills

Canonical page: https://capsules.run/skills/

Capsules use [The Agent Skills](https://agentskills.io) format for portable agent capabilities. Agent Skills make capsules accessible to many agents; capsules make skills verifiable by wrapping them with hashes, event records, capability gates, and output contracts.

## spacetime

Status: concept

Work product communication layer. It gives evolving surfaces a shared coordinate system for state, provenance, and continuation.

## MOGO

Status: coming soon

Code density optimizer with nested language-specific rules.

## Security Model

Nothing runs silently. A capsule-aware runtime should declare, review, grant, execute, and record skill use. Skill invocation events should include parameters, result hashes, status, and linkage to the prior chain state.
