Add openai-ads domain skill; fill uploads interaction skill stub

[CrestViewFl]

What

• domain-skills/openai-ads/ads-manager.md (new): field-tested map of the OpenAI Ads Manager beta (ads.openai.com) — campaign/ad-group/ad structure and which settings live at which level, the two create flows, placeholder-based field location (no stable ids), soft truncation warnings, async skeleton statuses, and the main trap: a stuck grey image attachment tile that hides the real file input until its X is clicked.
• interaction-skills/uploads.md: was an empty stub. Documented the three-tier upload approach: existing input[type=file] via DOM.setFileInputFiles, dynamic inputs via Page.setInterceptFileChooserDialog + fileChooserOpened → backendNodeId, and the stuck-preview case that reveals an input after removal.

Why

Learned while publishing a real campaign end to end (campaign → ad group → ad → image upload → publish → serving). The image-upload trap alone cost several probe rounds; the next agent should not pay that tax.

No secrets, account ids, or pixel coordinates included.

  • Added domain-skills/openai-ads/ads-manager.md: structure (campaign → ad group → ad), create flows, field locators by placeholder/value, soft truncation warnings, async skeleton states, and fix for the stuck grey image tile (click X to reveal the real file input).
  • Filled interaction-skills/uploads.md: 3-step upload approach—(1) direct input[type=file] via CDP DOM.setFileInputFiles, (2) dynamic inputs via Page.setInterceptFileChooserDialog + fileChooserOpened backendNodeId, (3) remove stale preview tiles when no chooser event; includes post-upload verification and drag-and-drop note.

Ollie (CTO) Review: APPROVED ✅

What this does: Adds an OpenAI Ads Manager domain skill (44 lines) documenting the campaign/ad-group/ad structure, create flows, field locators, and the grey image-tile upload trap. Also fills the uploads interaction skill stub (23 lines) with a three-tier upload approach using CDP APIs.

Assessment: Clean, field-tested documentation. No code changes. The image-tile trap documentation is genuinely valuable — saves agents from repeating probe rounds. No secrets or account identifiers included.

Good to merge.
