What's this

`skill-sidecar` is a sandboxed skill execution framework for AI agents. It runs as a sidecar container alongside your agent, exposing a high-performance **Rust HTTP API** that executes CLI tools and scripts on the agent's behalf.

The agent never touches credentials or CLI tools directly — it just calls `POST /skill/`.

Why should I care

Without a sidecar, your agent container needs every CLI tool, secret, and credential baked in. That means:

A bloated image that's hard to update
Credentials co-located with untrusted LLM-generated code
No isolation between the reasoning layer and the execution layer

With `skill-sidecar`:
