**Runtime and Registry for Agent Skills**

[](https://discord.com/invite/mMfxvMtHyS)

Discover, verify, and execute capabilities on demand.

Enact packages tools as portable skill bundles and runs them securely — locally, in containers, or remotely — with policy enforcement and cryptographic verification. Skills can be chained into workflows that mix deterministic execution with model reasoning.

Built for Autonomous Agents

Agents shouldn't ship with every tool preinstalled. They should acquire capabilities when needed.

**Discover by capability** — Search the registry for skills that solve the task:

enact search "resize images"

**Run instantly** — Execute without manual setup or environment wiring:

enact run alice/resizer --width 800

**Chain into workflows** — Combine skills and model reasoning into repeatable pipelines:

enact workflow run research-pipeline.yaml --input url=https://example.com

**Know what's available** — Agents and developers can inspect installed capabilities:

A Runtime — Not Just a Registry

Traditional package managers deliver code to developers. Enact delivers capabilities to autonomous systems with guarantees.

Without Enact	With Enact
Manual integration	Drop-in execution
Implicit trust	Verified signatures
Environment drift	Reproducible runtime
Secrets in code	Secure injection
Static installs	On-demand capabilities

npx launches code. A runtime governs execution.

Policy-Enforced Execution

The model decides what to run. Enact decides **whether and how** it runs.
