Make a small private app without leaving the conversation
When a recurring need is better served by an interface than another answer, EVO can shape a bounded private micro app and keep it inside the account AOS collection. Private App creation requires an active Echo plan or higher; Signal can still create reusable Skills within its plan limit.
The outcome this serves
Convert a repeated calculation, checklist, reference tool or small workflow into a reusable app surface that the user and EVO can operate in the same context.
Account requirement: Creating a private AOS App requires Echo or higher. Reusable Skill creation remains available on Signal, subject to its account limit. The membership center shows plan comparison and current purchasing state; new self-service checkout is paused until a same-release production payment receipt is verified.
Start with a verifiable request
Build a private [workflow] app with the smallest permissions, then verify and version it.
- Completion evidence
- The interface must show the genuinely completed result; external, paid, delayed or downloadable delivery must also expose the relevant runtime evidence or receipt.
- Failure state
- A refusal, boundary or error must remain visible and may not be labelled complete; failed delivery may not be charged as success.
- Public capability basis

How the request moves
- Describe the useful behavior
The user explains the result and essential inputs; EVO turns that into a constrained app contract.
- Build inside a sandbox
Capabilities, state, events and network access are limited by an explicit manifest and runtime budget.
- Preserve a versioned app
A successful app can remain in AOS, with integrity checks, pause and rollback rather than becoming a one-time code block.
What you receive
- A private AOS micro app with an icon and usable interface
- Versioned state and bounded capabilities
- A reusable surface EVO can reopen when the same need returns
What EVO will not pretend
- Signal does not include private App creation; it can create reusable Skills instead.
- Private generated apps are not published to a public marketplace.
- They cannot silently access credentials, unrestricted networks or other accounts.
- Some ideas still belong in a full external software project rather than the micro app sandbox.
Common questions
- Can I manage the app later?
- Private apps can be reopened and follow the available pause, rollback and lifecycle controls.
- Can EVO operate it too?
- Within the app manifest and account permissions, EVO and the owner can work against the same bounded state.
