Pins the T3 contract from c6ca605 to 9e12eca. One upstream commit:

• fix(server): allow requested WebMCP writes pingdotgg/t3code#26570: tools a web page exposes (WebMCP) may now write when the user asks. The old rule said they give data only. Both texts still forbid using them to show results.

Two contract files changed: preview/tools.ts (the preview_evaluate description) and orchestrationInstructions.ts (the Visuals and preview item). The plugin is unchanged, so no version bump.

Breaks a mapping

None.

• No tool was renamed or removed.
• skills/poteto-mode/references/t3-adapter.md never restates the page-tools rule. Its control-ui item drives preview_* "as T3's browser instructions say", so it picks up the new rule as is.
• The Visuals item still publishes with html_preview and html_render, which matches "Never use them to show results".

Opportunities

• Requested WebMCP writes: the control-ui item in skills/poteto-mode/references/t3-adapter.md could say that, when the request asks for browser work, a page's own tools may perform the requested action instead of clicks. Low value: no pstack skill targets pages that expose WebMCP tools.
