AI agent skill builder for methods worth reusing
Prostir is an AI agent skill builder for turning an SOP, checklist, playbook, or quality standard into a distinct Skill with one main instruction file, supporting material, validation, and version history. Reuse it across Agents, move it as a ZIP archive, or publish it as its own product.

What is getting in the way
Valuable know-how often lives in calls, templates, scattered documents, and one person's memory. Every handoff changes the method, copies drift apart, and each new project starts with the same explanation.
What changes
Keep the method in one portable Skill, validate its structure and references, publish an immutable version, and choose where it belongs: attached to your Agent, used by a Team, downloaded as an archive, or offered separately.

What you can verify
- A Prostir Skill has exactly one root SKILL.md plus optional references, assets, scripts, and evaluation files kept in the same portable product.
- Before publication, Prostir checks metadata, structure, references, unsafe files, and evaluation setup; every published version stays immutable.
- A Skill can be loaded by Agents when needed, attached to a Team, imported or exported as a ZIP, and offered separately under supported access and payment rules.
A good fit if
- You repeat the same SOP, review standard, checklist, or expert method across projects.
- You want the method to remain versioned and portable instead of hiding inside one Agent prompt.
Not the right fit if
- You need a stateful customer-facing Agent with its own sessions and published endpoint.
- You expect Prostir to execute arbitrary scripts from a Skill without a separate trusted runtime.
Questions before you decide
01Is a Skill just another prompt?
No. A prompt is usually copied into one conversation. A Skill is a portable, versioned folder that tells an Agent when and how to apply the method, what supporting material to load, and where its limits are.
02Can I sell the Skill without selling an Agent?
Yes. A published Skill can have its own access and purchase rules. Provider setup and the relevant marketplace gate still apply.
