Main features

1. generate_blocks(user_request, context, request, properties) — produce a full blocks + blocks_layout structure from a natural-language description (blocks_generator agent).

2. generate_block(user_request, block_type=None, ...) — produce a single block (blocks_generator_single agent).

3. rewrite_blocks(blocks, style=None, ...) and rewrite_block(block, style=None, ...) — rewrite text content in one or more blocks (block_rewriter / block_rewriter_single agents).

4. IBlockKnowledge named-utility registry — packages declare a block type’s description, JSON schema, example, text extractor, and sanitizer. The agent’s system prompt is built from these utilities.

5. BlocksKnowledgeSkill enricher — injects every registered block type’s schema + example into the agent’s system prompt.

6. BlocksContentProvider enricher — injects the current page’s block text into the user prompt (batched IBlockKnowledge lookups, no per-block ZCA queries).

7. Ships block knowledge for slate, image, columnsBlock, tabs_block. Custom block types register their own via <genai:blockKnowledge>.

8. @llm-generate-blocks and @llm-rewrite-blocks REST endpoints.

Install

• Add eea.genai.blocks to your requirements.txt.

• Install the GenericSetup profile.

• The four default agents are registered automatically via ZCML and can be overridden by name via the core control panel agents_json.

Adding a new block type

In your addon’s configure.zcml:

<genai:blockKnowledge
    block_type="my_block"
    title="My Block"
    class=".knowledge.MyBlockKnowledge"
/>

In knowledge.py:

from eea.genai.blocks.interfaces import BlockKnowledge

class MyBlockKnowledge(BlockKnowledge):
    description = "Describe what the block is for"
    schema = '{"@type": "my_block", "value": "..."}'
    example = '{"@type": "my_block", "value": "hello"}'

    def text_extractor(self, block):
        return block.get("value", "")

    def block_sanitizer(self, block):
        return block  # post-LLM cleanup, return canonical dict

Generation/rewriting agents will pick up the new block type automatically — no change to agent config required.
