# XLSX Skill Thin wrapper that routes XLSX creation, editing, and analysis requests to the `sheet-agent`, which manipulates spreadsheets using openpyxl and pandas via Bash. ## 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 `/sheet` command - User runs `/edit` command with a .xlsx file ### Implicit Invocation (during task implementation) When an implementing agent encounters any of these patterns: **Plan step language patterns**: - "Create spreadsheet [file].xlsx with [content]" - "Create xlsx [file] with [columns/data]" - "Edit [file].xlsx to [change]" - "Edit spreadsheet [file] to [change]" - "Add formulas to [file].xlsx" - "Add formatting to [file].xlsx" - "Update [file].xlsx with [data]" - "Analyze [file].xlsx for [purpose]" **File extension detection**: - Target file has extension: `.xlsx`, `.xlsm` - Operation type: create, edit, update, modify, analyze, add formulas, add formatting **Task description keywords**: - "XLSX creation" - "spreadsheet creation" - "xlsx editing" - "spreadsheet editing" - "add formulas" - "add formatting" - "xlsx analysis" ### When NOT to Trigger Do not invoke for: - Spreadsheet-to-table conversion (use skill-filetypes-spreadsheet for /table) - Simple CSV/TSV reading (use Read tool directly) - Grant budget creation (use skill-budget for /budget) - PDF/DOCX operations (use other filetypes skills) - Presentation operations (use skill-presentation) --- ## Execution ### 1. Input Validation Validate required inputs: - `file_path` - Must be provided; for edit/analyze must exist; for create mode may not exist yet - `instruction` - Natural language instruction describing the desired operation (required) - `mode` - One of: "create", "edit", "analyze" (inferred from context and file existence) ```bash # For edit mode: validate source exists and is xlsx/xlsm if [ "$mode" = "edit" ]; then if [ ! -f "$file_path" ]; then return error "XLSX file not found: $file_path" fi if [[ "${file_path##*.}" != "xlsx" && "${file_path##*.}" != "xlsm" ]]; then return error "Source must be a .xlsx or .xlsm file: $file_path" fi fi # For analyze mode: validate source exists if [ "$mode" = "analyze" ]; then if [ ! -f "$file_path" ]; then return error "File not found for analysis: $file_path" fi fi # For create mode: validate xlsx extension if [ "$mode" = "create" ]; then if [[ "${file_path##*.}" != "xlsx" && "${file_path##*.}" != "xlsm" ]]; then return error "New file must have .xlsx or .xlsm extension: $file_path" fi fi ``` ### 2. Context Preparation Prepare delegation context: ```json { "file_path": "/absolute/path/to/spreadsheet.xlsx", "instruction": "Create a budget tracking spreadsheet with categories, monthly columns, and SUM formulas", "mode": "create", "metadata": { "session_id": "sess_{timestamp}_{random}", "delegation_depth": 1, "delegation_path": ["orchestrator", "xlsx", "skill-sheet"] } } ``` ### 3. Invoke Agent **CRITICAL**: You MUST use the **Agent** tool to spawn the sheet-agent. **Required Tool Invocation**: ``` Tool: Agent (NOT Skill, NOT Plan) Parameters: - subagent_type: "sheet-agent" - prompt: [Include file_path, instruction, mode, metadata] - description: "{mode} {file_path}: {instruction}" ``` **DO NOT** use `Skill(sheet-agent)` - this will FAIL. Agents live in `.claude/agents/` or extension agent directories, not `.claude/skills/`. The Skill tool can only invoke skills from `.claude/skills/`. The agent will: - Detect available tools (openpyxl, pandas) - Execute the requested operation (create, edit, or analyze) - Validate the output file - Return standardized JSON result ### 4. Return Validation Validate return matches `subagent-return.md` schema: - Status is one of: created, edited, analyzed, partial, failed - Summary is non-empty and <100 tokens - Artifacts array present with output file path - Metadata contains session_id, agent_type, delegation info **Status value rules**: - `created` - New file successfully created - `edited` - Existing file successfully modified - `analyzed` - File read and analysis returned - `partial` - Some operations succeeded, others failed - `failed` - No operations applied, error occurred - NEVER use "completed" (triggers Claude stop behavior) ### 5. Return Propagation Return validated result to caller without modification. --- ## Return Format See `.claude/context/formats/subagent-return.md` for full specification. Expected successful return: ```json { "status": "created", "summary": "Created budget.xlsx with 4 category rows, monthly columns Jan-Dec, SUM formulas for totals, and currency formatting.", "artifacts": [ { "type": "implementation", "path": "/absolute/path/to/budget.xlsx", "summary": "XLSX workbook with formulas and formatting" } ], "metadata": { "session_id": "sess_...", "agent_type": "sheet-agent", "delegation_depth": 2, "delegation_path": ["orchestrator", "xlsx", "skill-sheet", "sheet-agent"], "tool_used": "openpyxl", "mode": "create", "sheets": 1, "rows": 6, "columns": 14 }, "next_steps": "Open spreadsheet to verify formulas and formatting" } ``` --- ## Error Handling ### Input Validation Errors Return immediately with failed status if file not found, not a .xlsx/.xlsm, or instruction is empty. ### Unsupported Format Return failed status if file extension is not .xlsx or .xlsm (for create/edit). Suggest using /convert or /table for other spreadsheet operations. ### Agent Errors Pass through the agent's error return verbatim. ### Tool Not Available Return failed status with installation instructions for openpyxl and pandas. --- ## MUST NOT - Run the postflight step (git commit, status update) -- that is the command's responsibility - Modify the return from sheet-agent before propagating - Load context files eagerly -- only reference them when needed - Use the Skill tool to invoke sheet-agent (use Agent tool instead)
