Fawx Skills Registry

The official skill registry for Fawx. Skills are WASM binaries that run sandboxed inside the Fawx engine.

Security Model

Every skill in this registry is:

• Sandboxed in WebAssembly. No filesystem access, no environment variables, no process spawning.
• Capability-gated. Each skill declares what it needs (network, storage, etc.) and gets nothing more.
• Signed with Ed25519. Install fails if the signature doesn't match a trusted publisher key.
• Self-contained. No transitive dependencies. What you install is what runs.

For Skill Authors

Skills are Rust compiled to wasm32-unknown-unknown. See the Fawx Skills SDK for the host API, manifest format, and authoring guide.

Manifest Format

Every skill includes a manifest.toml:

name = "my-skill"
version = "1.0.0"
description = "What this skill does"
author = "Your Name"
api_version = "host_api_v1"
capabilities = ["network"]
entry_point = "run"

[[tools]]
name = "my_tool"
description = "What this tool does"

[[tools.parameters]]
name = "query"
type = "string"
description = "Parameter description"
required = true

Capabilities

Skills declare only the capabilities they need:

• network — Make HTTP requests (outbound only, capability-gated)
• network_restricted — HTTP requests limited to specific domains
• storage — Persistent key-value storage (64KB quota per skill)
• notifications — Send user notifications
• sensors — Read sensor data
• phone_actions — Control phone (high privilege)

A skill with no capabilities runs in a fully isolated sandbox with zero external access.
