New Experiment: AI-assisted custom block creation

[jeffpaul]

What problem does this address?

Explore a new experiment for creating custom WordPress blocks from natural-language prompts, informed by the former Telex AI project from Automattic. The experiment should allow a user to describe what they want to build, then use the configured AI provider to determine the most appropriate implementation, such as a Pattern, Block Style, Block Variation, or Custom Block, and generate a usable result.

@georgestephanis has started exploring this concept in https://github.com/georgestephanis/ai-block-creator, which could serve as a useful starting point for bringing the idea into the WordPress AI plugin.

What is your proposed solution?

The initial goal is experimentation and learning, not a production-ready block-generation workflow:

• Add custom block creation as an opt-in experiment
• Accept a natural-language description of the desired block or experience
• Determine whether the request is best fulfilled as a Pattern, Block Style, Block Variation, or Custom Block
• Generate the necessary implementation and provide a way to preview/test the result
• Investigate whether George's existing work can be reused or adapted rather than starting from scratch
• Consider future integration with the AI Workspace or similar developer-focused AI tooling

Why is this important to you?

I have searched existing issues and this is not a duplicate.

I'd like to take this one up.

Before writing much new code, want to dig into @georgestephanis's ai-block-creator since it already does most of this — intent classification (Pattern/Style/Variation/Custom Block), schema-validated gen with repair pass, live preview, allowlist so AI isn't offered every block on site. If it ports cleanly onto this plugin's AiClient/settings setup, rather adapt than start blank.

First PR kept tight: prompt → classify → generate → validate → preview/insert. Leave persistent block library for follow-up.

Questions: OK porting from ai-block-creator (same GPL license)? preference on experiment name/ID? fine treating block library + screenshot/voice input as separate follow-ups?

Happy to be assigned, start with short reuse spike then MVP PR.

@zeus2611 Would you like me to add you to the ai-block-creator plugin for any changes you'd like to do there (or prs to fire off) to get it more compatible with merging?

Thanks @georgestephanis, I'd appreciate that. Access would let me get the plugin ready for merging (AiClient, settings, WP coding standards) before I port it here.
