Workflow excerpts are reading aids, not executable instructions from Codez. No third-party Skill was run to produce this page.

The purpose and workflow passages below are upstream material, organized and translated for reading. They are distinct from the separately labeled Codez editorial analysis.

What this Skill does

How the upstream workflow works

Step 1: Create Agent Identity Blueprint

Sponsors are required and must be User objects — ServicePrincipals and Groups are rejected.

Upstream passage · L105 ↗

Step 2: Create BlueprintPrincipal

> This step is mandatory. Creating a Blueprint does NOT auto-create its > service principal. Without this, Agent Identity creation fails with: > 400: The Agent Blueprint Principal for the Agent Blueprint does not exist. If implementing idempotent scripts, check for and create the BlueprintPrincipal even when the Blueprint already exists (a previous run may have created the Blueprint but crashed before creating the SP).

Requirements and setup

No short requirements passage was selected from this file. This does not mean the Skill has no dependencies. Check the repository setup instructions and referenced files.

Limits and quality checks

No separate limits passage was selected from this file. This does not mean the Skill is safe for every input or environment. Review the complete source and validate your own result.

Start with a safe trial

Check the supported host and the repository installation instructions. Keep the Skill directory and its referenced scripts, assets and documentation together; SKILL.md alone may omit dependencies.
Give the agent your real input, desired output and acceptance criteria. Invocation syntax and available tools depend on the host; this site does not assume a universal install command.
Try the source workflow in a disposable project or on a copy. Review operations that change files, remote services or billable resources before allowing them.
Validate the output against the source quality checks and your own requirements. A successful trigger or a high repository Star count does not establish a correct result.
