- No malware found by supply-chain analysis.Pass
- Only part of the dependency tree could be resolved (95 of 99), so this covers what we could see, not the whole tree.Partial
- No install/post-install scripts declared.Pass
- Only part of the dependency tree could be resolved (95 of 99), so this covers what we could see, not the whole tree. View diagnostics → Partial

The dependency tree was only partially resolved, so these counts may be incomplete.
The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability.
brew_world ~65
Create YOUR OWN world through the guest door — no account needed. Returns a build token (uc_st_) for the bridge. Guests get three creations; editing is unlimited. Sign in on the site later and everything transfers to your account.
| Name | Type | Req | Description |
|---|---|---|---|
| name | string | yes | The world's name |
No output schema declared.
No examples provided.
bridge ~104
Send a command (or {"commands":[...]} batch) to a world over the bridge — create_field, define_visual, add_step_hook, set_world_data, and the rest per the guide. Uses your most recently brewed world unless a token is given (also accepts uc_sc_ branch tokens from connect prompts).
| Name | Type | Req | Description |
|---|---|---|---|
| command | object | yes | The bridge command object |
| token | string | — | World token (uc_st_/uc_sc_). Defaults to your latest brewed world. |
No output schema declared.
No examples provided.
browse_shelf ~33
Every world on the cafe's shelf, with play URLs. Public worlds' full source is readable via read_world_source.
Input schema present but exposes no named parameters.
No output schema declared.

my_worlds ~25
The worlds you have brewed in this session, with their tokens and view URLs.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
read_guide ~39

Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
read_world_source ~59
A public world's complete source — WGSL visuals, step-hook code, fields, params. The shelf is a library, not a vault: learn techniques from working worlds.

No output schema declared.
No examples provided.
world_state ~83
Read a world's FULL current source over the bridge — every field, every visual's complete WGSL, every step-hook's complete JS code, plus worldData, params, modules, and interaction rules. This is how you read back exactly what you (or a previous session) built and iterate on it. Defaults to your latest brewed world.

| token | string | — | — |
