[Agents & Runtime]

Extend agents with code you control.

Skills are reusable instructions. Tools are TypeScript functions. Package both with AFPS.

[01 · Why it matters]

Pre-built is nice. Yours is necessary.

Every real product has custom logic: pricing rules, approval thresholds, internal APIs, domain lingo. No catalog covers it.

Appstrate lets you write tools in TypeScript and ship them as packages. Agents discover them automatically; versioning and dependencies follow semver.

[02 · How it works]

Write once. Version. Share.

A tool is a function. A skill is a markdown file with YAML frontmatter. Both package into AFPS archives.
