A screen implementation procedure that selects supported controls and writes one screen's YAML definition from an approved design and data plan. YAML is a text format commonly used for structured configuration.

In plain words
What is it for?
Use it to build or repair one app screen with the chosen controls and their configuration.
Why use it?

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

canvas-create-builder scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 44 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Implement One Screen

Read the original request, assigned composition and relevant requirement/action IDs, [working directory]/create-design.md, [working directory]/create-bindings.md, and the relevant current discovery decisions. The coordinator supplies the approved revision tuple, logical screen ID, target file, YAML screen key and unique control-name prefix. Confirm they match before writing. Do not create another implementation plan.

Own exactly the assigned screen YAML file. Do not edit App.pa.yaml, _EditorState.pa.yaml, bindings, experience artifacts or another screen. Do not delegate, list resources, discover data/APIs, compile or address the app user. A repair assignment means inspect and patch the existing screen, not regenerate it.

Direct Control Descriptions

Choose controls from the feasible candidates and apply Control authority in ${PLUGIN_ROOT}/references/CreateBuilderCore.md. Describe selected types directly before configuration; discovery supplies candidates/constraints, not replacement metadata. Route missing contracts or disproved feasibility back to discovery.

Implementation

Read the core, ${PLUGIN_ROOT}/references/CreateConformance.md and applicable CREATE topic modules from the core's ownership map. These are the complete routine checks; only conformance's explicit specialist routes require a bounded legacy check. Reuse complete references/descriptions in this context. None authorizes an unapproved experience change.

Use final names, source/schema identifiers, shared state and initialization ownership from bindings. Do not invent shared globals or initialize coordinator-owned collections. Preserve the approved composition and shared presentation/shell contract rather than substituting a stock layout or reading peer screens to infer missing decisions. Shared gaps go to the coordinator.

Apply ${PLUGIN_ROOT}/references/CreateGalleryLayout.md's dataset-bound rules to supplied list-source contracts, including missing or invalidated assumptions.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
