skill-filetypes-spreadsheet

# Spreadsheet Skill Thin wrapper that routes spreadsheet-to-table operations to the `filetypes-spreadsheet-agent`. ## Context Pointers Reference (do not load eagerly): - Path: `.claude/context/formats/subagent-return.md` - Purpose: Return validation - Load at: Subagent execution only Note: This skill is a thin wrapper. Context is loaded by the delegated agent, not this skill. ## Trigger Conditions This skill activates when: ### Direct Invocation - User explicitly runs `/table` command - User requests spreadsheet to table conversion in conversation ### Implicit Invocation (during task implementation) When an implementing agent encounters any of these patterns: **Plan step language patterns**: - "Convert spreadsheet to table" - "Create LaTeX table from Excel" - "Import data from XLSX" - "Generate Typst table from CSV" - "Extract table data from spreadsheet" **File extension detection**: - Source file has extension: `.xlsx`, `.xls`, `.csv`, `.ods` - Target mentions: "LaTeX table", ".tex", "Typst table", ".typ" **Task description keywords**: - "spreadsheet conversion" - "Excel to table" - "data table" - "tabular data" ### When NOT to trigger Do not invoke for: - Document conversions (use skill-filetypes) - Presentation conversions (use skill-presentation) - Reading spreadsheets without table generation - Spreadsheets already in LaTeX/Typst format --- ## Execution ### 1. Input Validation Validate required inputs: - `source_path` - Must be provided and file must exist - `output_path` - Optional, defaults to source dir with .tex extension - `output_format` - Optional, defaults to "latex" ```bash # Validate source exists if [ ! -f "$source_path" ]; then return error "Source file not found: $source_path" fi # Validate source is spreadsheet format source_ext="${source_path##*.}" case "$source_ext" in xlsx|xls|csv|ods) ;; # Valid *) return error "Not a spreadsheet format: .$source_ext" ;; esac # Determine output path if not provided if [ -z "$output_path" ]; then source_dir=$(dirname "$source_path") source_base=$(basename "$source_path" | sed 's/\.[^.]*$//') case "$output_format" in latex|tex) output_path="${source_dir}/${source_base}.tex" ;; typst|typ) output_path="${source_dir}/${source_base}.typ" ;; *) output_path="${source_dir}/${source_base}.tex" ;; esac fi ``` ### 2. Context Preparation Prepare delegation context: ```json { "source_path": "/absolute/path/to/data.xlsx", "output_path": "/absolute/path/to/data.tex", "output_format": "latex", "sheet_name": null, "metadata": { "session_id": "sess_{timestamp}_{random}", "delegation_depth": 1, "delegation_path": ["orchestrator", "table", "skill-filetypes-spreadsheet"] } } ``` ### 3. Invoke Agent **CRITICAL**: You MUST use the **Agent** tool to spawn the agent. **Required Tool Invocation**: ``` Tool: Agent (NOT Skill, NOT Plan) Parameters: - subagent_type: "filetypes-spreadsheet-agent" - prompt: [Include source_path, output_path, output_format, sheet_name, metadata] - description: "Convert {source_path} to {output_format} table" ``` The agent will: - Detect available tools (pandas, openpyxl, xlsx2csv) - Read spreadsheet data - Generate formatted table output - Return standardized JSON result ### 4. Return Validation Validate return matches `subagent-return.md` schema: - Status is one of: converted, partial, failed - Summary is non-empty and <100 tokens - Artifacts array present with output file path - Metadata contains row/column counts ### 5. Return Propagation Return validated result to caller without modification. --- ## Return Format Expected successful return: ```json { "status": "converted", "summary": "Successfully converted data.xlsx to LaTeX table using pandas", "artifacts": [ { "type": "implementation", "path": "/absolute/path/to/data.tex", "summary": "LaTeX table with 5 columns, 100 rows" } ], "metadata": { "session_id": "sess_...", "agent_type": "filetypes-spreadsheet-agent", "delegation_depth": 2, "tool_used": "pandas+openpyxl", "rows": 100, "columns": 5 }, "next_steps": "Include table in document" } ``` --- ## Error Handling ### Input Validation Errors Return immediately with failed status if source file not found or not a spreadsheet. ### Unsupported Format Return failed status with clear message about supported formats. ### Agent Errors Pass through the agent's error return verbatim. ### Tool Not Available Return failed status with installation instructions.
