Single tool 'execute_skill_action' has critical definition gaps. Description is vague (67 chars, below 10-char minimum for clarity) and does not explain WHAT the tool does, WHEN to use it, or what it returns. Input schema exists but parameter 'query_payload' lacks any description, LLMs cannot infer what payload format is expected. No output schema documented. Tool name uses generic verb 'execute' rather than domain-specific action. No error handling guidance. No examples of valid payloads or expected responses. Fails 6 of 7 definition quality dimensions.

• Rename tool from 'execute_skill_action' to a domain-specific verb_noun pair (e.g., 'extract_table_from_image', 'parse_document_structure'). This helps LLMs infer intent from the name alone.
• Expand tool description to 100-200 characters explaining: (1) What it does (extracts table structure from images), (2) When to use it (when user provides an image with tabular data), (3) What it returns (structured table with rows, columns, merged cells resolved). Example: 'Extract table structure from images. Detects tables, resolves merged cells, and returns markdown-formatted output. Use when processing spec sheets, pricing tables, or data-heavy documents.'
• Add description to 'query_payload' parameter: 'Input payload as JSON string. Must include: image_uri (URL or base64 image), expected_columns (array of column names). Example: {"image_uri": "https://...", "expected_columns": ["Feature", "Price"]}'
• Document output schema in tool description or as a separate schema field. Specify: extraction_id (string), detected_table_count (integer), reconstructed_rows_count (integer), reconstructed_columns_count (integer), merged_cells_resolved_count (integer), bounding_box_coverage (float 0-1), clean_markdown_table (string), structured_dossier_url (string).
• Add error handling: document failure modes (invalid image, no table detected, malformed payload) and recovery steps. Example: 'If no table detected, try: (1) verify image URL is accessible, (2) ensure image contains a clear table structure, (3) check expected_columns match actual table headers.'
