Generate, edit, or compose images via OpenAI's gpt-image family.

BEFORE the FIRST call in a conversation, read the MCP resource image-guide://full for the full prompting guide (structure, realism rules, edit/compose modes, when to set quality/fidelity). You only need to read it once per conversation.

Mode is selected by references_paths:

• omitted/empty -> generate from text alone

• 1 path -> edit that image

• 2..16 paths -> generate using them as labeled references

Model routing is automatic and reported in the response:

• background='transparent' -> gpt-image-1.5 (gpt-image-2 rejects alpha)

• everything else -> gpt-image-2 (flagship)

Returns metadata only — the file is written to output_path. Read the file with the Read tool only if you need to verify the result.
