skill-filetypes: скилл маршрутизации и конвертации файлов

--- name: skill-filetypes description: File format conversion routing with specialized sub-agent dispatch allowed-tools: Task --- # Filetypes Skill Thin wrapper that routes file format operations to the `filetypes-router-agent`, which then delegates to specialized sub-agents based on file type. ## 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 agents, not this skill. ## Trigger Conditions This skill activates when: ### Direct Invocation - User explicitly runs `/convert` command - User requests file format conversion in conversation ### Implicit Invocation (during task implementation) When an implementing agent encounters any of these patterns: **Plan step language patterns**: - "Extract text from [file].pdf" - "Extract content from [file]" - "Convert [file] to markdown" - "Convert [file] to PDF" - "Generate PDF from [documentation/file]" - "Read content from [file].docx" - "Create PDF version of [file]" - "Parse [file].pdf for content" - "Import [file] content" **File extension detection**: - Source file has extension: `.pdf`, `.docx`, `.xlsx`, `.pptx`, `.html` - Target mentions: "markdown", ".md", "PDF", ".pdf" **Task description keywords**: - "document conversion" - "format transformation" - "extract from PDF" - "generate PDF" ### When NOT to trigger Do not invoke for: - Reading source code files (.py, .js, .lean, etc.) - Viewing images without extraction - Operations that don't involve format conversion - Files already in the target format - Spreadsheet-specific operations (use skill-spreadsheet) - Presentation-specific operations (use skill-presentation) --- ## Execution ### 1. Input Validation Validate required inputs: - `source_path` - Must be provided and file must exist - `output_path` - Optional, defaults to source dir with appropriate extension ```bash # Validate source exists if [ ! -f "$source_path" ]; then return error "Source file not found: $source_path" fi # Determine output path if not provided if [ -z "$output_path" ]; then source_dir=$(dirname "$source_path") source_base=$(basename "$source_path" | sed 's/.[^.]*$//') source_ext="${source_path##*.}" # Infer target extension case "$source_ext" in pdf|docx|xlsx|pptx|html) output_path="${source_dir}/${source_base}.md" ;; md) output_path="${source_dir}/${source_base}.pdf" ;; *) return error "Cannot infer output format for .$source_ext" ;; esac fi ``` ### 2. Context Preparation Prepare delegation context: ```json { "source_path": "/absolute/path/to/source.pdf", "output_path": "/absolute/path/to/output.md", "metadata": { "session_id": "sess_{timestamp}_{random}", "delegation_depth": 1, "delegation_path": ["orchestrator", "convert", "skill-filetypes"] } } ``` ### 3. Invoke Router Agent **CRITICAL**: You MUST use the **Task** tool to spawn the router agent. **Required Tool Invocation**: ``` Tool: Task (NOT Skill) Parameters: - subagent_type: "filetypes-router-agent" - prompt: [Include source_path, output_path, metadata] - description: "Convert {source_path} to {output_path}" ``` **DO NOT** use `Skill(filetypes-router-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 router will: - Detect source and target formats - Select appropriate sub-agent (document, spreadsheet, presentation) - Delegate to sub-agent for actual conversion - Return standardized JSON result ### 4. Return Validation Validate return matches `subagent-return.md` schema: - Status is one of: converted, extracted, partial, failed - Summary is non-empty and <100 tokens - Artifacts array present with output file path - Metadata contains session_id, agent_type, delegation info ### 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": "converted", "summary": "Successfully converted document.pdf to document.md using markitdown", "artifacts": [ { "type": "implementation", "path": "/absolute/path/to/document.md", "summary": "Converted markdown document" } ], "metadata": { "session_id": "sess_...", "agent_type": "document-agent", "delegation_depth": 2, "delegation_path": ["orchestrator", "convert", "skill-filetypes", "filetypes-router-agent", "document-agent"], "tool_used": "markitdown" }, "next_steps": "Review converted document" } ``` --- ## Error Handling ### Input Validation Errors Return immediately with failed status if source file not found. ### Unsupported Format Return failed status with clear message about supported formats. ### Router/Subagent Errors Pass through the router/subagent's error return verbatim. ### Tool Not Available Return failed status with installation instructions.
