Single tool 'execute_skill_action' has critical definition gaps. Description is present (97 chars) but vague, does not explain WHAT the tool does, WHEN to use it, or what it returns. Input schema exists with one parameter 'query_payload' (type: string) but lacks any description of what payload format is expected, what fields it contains, or examples. No output schema documented, LLM cannot predict return structure. Tool name uses verb but is overly generic ('execute_skill_action' could mean anything). No error handling guidance, no parameter constraints, no idempotency guarantees. Fails 6 of 7 critical checks in Dimension 1.

• Add detailed output schema documenting all response fields (status, message, occlusion_resolution_id, element_now_clickable, etc.) with types and descriptions.
• Expand tool description to 100-200 chars: explain that it resolves viewport occlusions by detecting overlays (modals, banners) and executing dismissal actions or scroll offsets to make target elements clickable.
• Add description to 'query_payload' parameter: specify expected JSON structure (e.g., {"target_element_id": string, "viewport_bounds": {width, height}}) and document required vs optional fields.
• Document error cases: what happens if element not found, if occlusion cannot be resolved, if payload is malformed. Provide recovery guidance (e.g., 'If element not found, try search_elements() first').
• Rename tool to 'resolve_element_occlusion' or 'dismiss_overlay_and_scroll' to clarify intent and match verb_noun naming convention.
