Spectra (Ultimate Addons for Gutenberg)

Technical documentation for using Respira with Spectra, also known as Ultimate Addons for Gutenberg (UAG).

Spectra is a block library that extends the WordPress block editor with advanced sections, containers, and design blocks. It is one of Respira's 16 supported page builders, with full read and write.

Data Structure

Spectra does not use a separate storage format. Its blocks are stored as native WordPress blocks in post_content, the same as any Gutenberg page. Spectra blocks carry the spectra/* or uagb/* namespace:

<!-- wp:uagb/container {"block_id":"a1b2c3"} -->
  <!-- wp:uagb/advanced-heading {"headingTitle":"Welcome"} /-->
  <!-- wp:uagb/buttons -->
    <!-- wp:uagb/buttons-child {"label":"Get Started"} /-->
  <!-- /wp:uagb/buttons -->
<!-- /wp:uagb/container -->

Because Spectra is block-based, Respira edits Spectra blocks natively through the same path it uses for core Gutenberg blocks. There is no shortcode parsing or custom serialization in the middle.

Priming

Prime once at the start of a session so the agent builds and edits in blocks, not raw HTML:

"This is a Spectra (UAG) site. Build and edit with Spectra and core blocks, not raw HTML, and duplicate any live page before editing."

What Respira can do

• Read the full block structure of any Spectra page and report on it
• Update text, headings, and buttons inside Spectra blocks (uagb/advanced-heading, uagb/buttons, uagb/info-box, and the rest of the Spectra block set)
• Find blocks by type, content match, or block anchor
• Add or remove sections while keeping the page editable in the block editor
• Preserve all existing block attributes and styling on every write

The workflow is the same as core Gutenberg because Spectra blocks are just namespaced WordPress blocks. For the shared block workflow, block identification, and prompt patterns, see Gutenberg (Block Editor).

FAQ

Does Respira edit Spectra blocks natively or convert them?

Natively. Respira reads and writes Spectra blocks in place through the WordPress block registry. Nothing is flattened to HTML and nothing is converted to a different builder.

What if a page has both Spectra and plain Gutenberg blocks?

That is normal and fully supported. A page only registers as a Spectra page when it contains at least one spectra/* or uagb/* block. Either way, every block on the page stays editable.
