Create a prompt
A prompt in EvalGate is a versioned, content-hashed message template. You author drafts, test them, send them for review, and publish an approved version to a protected environment.Step 1 — Open Prompt Hub
In the sidebar, click Prompts, then New prompt.
Step 2 — Author the first version
Give the prompt a stable key (for example,checkout-assistant-system). The
key is the public identity; versions are immutable and content-hashed under it.
Write the message content. You can include tool definitions and variables. Save
the draft.
Step 3 — Test against the Gateway
Before review, run a Gateway test to confirm the prompt compiles and the model accepts it. This needs a connected provider key.Step 4 — Submit for review
Click Submit for review. A reviewer with theprompt:publish permission can
approve the version. Until then, it is a draft and cannot be served by a
protected alias.
Step 5 — Publish to an environment
After approval, publish the version to a protected environment alias (for example,production). The alias resolves that exact version — never a draft —
and every consumer retains the exact versionId and contentHash.
