Assist is a platform where teams can build, host, and deploy internal AI software and agents in one place — giving companies a safe, controlled environment to standardize workflows and improve operations.

What are sandcastles?

Sandcastles are purpose-built internal apps created by non-technical teams on the Assist platform. They allow employees to build custom tools and workflows without engineering resources.

How much does Assist cost?

Assist uses pay-as-you-go pricing: provider costs + 5%, $0.17 per 1k tool calls, with no seat fees. Enterprise custom pricing is also available.

Do we need engineers to use Assist?

No. Assist is designed for non-technical teams to build and deploy AI tools. Engineers can use it too, but it doesn't require engineering resources to get started.

Governing Agent Skill Versions

Use version management to review Agent Skill changes before they affect operational agents. For mid-sized companies cleaning up scattered AI usage, this prevents a useful workflow from turning into an unmanaged prompt collection again.

Permission levels

Level	What it allows
Read	View the Agent Skill, approved files, and attachment information visible to you.
Edit	Create drafts, edit draft files, submit drafts, and attach readable versions when you can edit the target agent.
Admin	Approve or reject pending versions and manage the Agent Skill for the workspace.

Version states

State	Meaning
Draft	Editable version. Use this for writing and testing changes.
Pending	Submitted for review. It is read-only until approved or rejected.
Approved	Reviewed version that can be mounted for normal agent use.
Rejected	Historical version that was not accepted. Create a new draft to continue work.

Steps

1. Open Versions

Open the Agent Skill and select Versions. Each version shows its status, short ID, commit message, and creation time.

2. Choose a version

Click a version to inspect it. The version selector at the top also lets you switch between versions.

3. Create a new draft

Click New Draft from an approved version. Assist forks the latest approved version by default.

Only one open draft can exist at a time for a skill. Finish, delete, or submit the current draft before creating another.

4. Submit for review

After saving draft edits, click Submit. The draft becomes pending.

Use the commit message to explain the workflow reason for the change, such as:

Add review rule for customer-facing AI drafts
Update support escalation summary format
Add examples from sales follow-up cleanup

5. Approve or reject

Admins can approve or reject pending versions.

If rejecting a version, enter a reason that tells the author what to fix. The author can create a new draft from an approved version and apply the feedback.

6. Upgrade mounted agents

Approving a version does not automatically change mounted agents. Open Usage and click Upgrade on any mount that should move to the latest approved version.

Recommended review checklist

SKILL.md says when the skill should be used.
The Agent Skill does not ask the agent to use unavailable tools.
The workflow has clear input requirements.
Customer-facing or sensitive outputs require human review when appropriate.
Supporting examples are current and do not contain private data.
The Agent Skill is scoped correctly as workspace or personal.
The test agent follows the skill in the expected workflow.

Rollout pattern for AI cleanup

Use a staged rollout when the skill standardizes a workflow employees already use informally.

Create a draft from the best existing prompt or workflow.
Remove private data and unclear assumptions.
Submit the draft with a plain-language summary of what changed.
Have the department owner or workspace admin approve it.
Attach or upgrade one operational agent first.
Review real output with the team using the workflow.
Upgrade additional agents after the output is accepted.

For higher-risk workflows, keep a lightweight release note in a supporting file such as /release-notes/2026-05-support-summary.md. Include what changed, who approved it, and which agents should move to the new version.
