exstruct-cli

name: exstruct-cli description: Use ExStruct CLI to validate, inspect, create, and edit Excel workbooks safely. Trigger when an agent needs exstruct patch, exstruct make, exstruct validate, exstruct ops list, or exstruct ops describe, especially for create-vs-edit decisions, dry-run workflows, backend constraints, or safe workbook-edit guidance.

ExStruct CLI

Use the existing editing CLI as the default local operational interface for ExStruct workbook create/edit requests.

Select a command

• Use exstruct make when the user wants a new workbook created and populated.
• Use exstruct patch when the user wants an existing workbook edited.
• Use exstruct validate when workbook readability is uncertain or before a risky edit on an unfamiliar file.
• Use exstruct ops list when the required operation is still unclear.
• Use exstruct ops describe <op> when you know the likely op name but need the exact schema or constraints.
• Hand the workflow off to MCP when the user needs host-owned path policy, transport mapping, artifact mirroring, or other server-managed behavior.

Safety rules

• Do not invent unsupported patch ops.
• Do not apply destructive edits immediately when the request is ambiguous.
• Prefer --dry-run before risky edits.
• Pin --backend openpyxl when the dry run and the real apply must use the same engine.
• Explain backend-specific failures directly instead of hiding them behind a generic retry.

Workflow

1. Decide whether the request is create, edit, or actually an MCP-hosted task.
2. Identify the needed op or inspect the public op schema.
3. Validate the workbook when the file, backend, or request is uncertain.
4. Run --dry-run for risky edits and inspect PatchResult.
5. Apply the real edit only after the planned change is acceptable.
6. Verify the result with the lightest step that still matches the user's risk.
