What FileMaker XMLsnippet Claude Skill does

Reverse-engineered specification of FileMaker's undocumented script XML paste behaviour, including a fully verified step ID dictionary and the hidden paste-handler rules that make a pasted script work or silently fail. Packaged as a Claude skill that generates accurate, pasteable script XML.

FileMaker Script XML Specification

Reverse-engineered specification of FileMaker's undocumented `fmxmlsnippet` clipboard format. Every step ID, element ordering rule, and silent failure mode, established through empirical round-trip testing against production FileMaker solutions.

Developed by Andrew Kear of [Clockwork Creative Technology](https://www.clockworkct.co.uk) and shared openly with the FileMaker/Claris community.

Why this exists

FileMaker's Script Workspace accepts pasted scripts in a specific XML format. Claris has never published a specification for it. Get the XML wrong and FileMaker accepts it silently, dropping data without any error message.

This specification documents what the paste handler actually accepts: 220 step IDs, canonical XML skeletons for every step, the element ordering constraints that cause silent drops when violated, and the calculation slot binding rules that cause multi-slot steps to misbind.

What it catches

The specification documents several classes of silent failure that are invisible in the Script Workspace after paste:

**Set Variable name drop.** If the variable name element is emitted as a single-letter tag instead of the canonical four-letter `Name` form, FileMaker pastes the step with no variable name. No error. No warning. You find out when the script runs.

**Calculation slot misbinding.** Install OnTimer Script, Perform JavaScript in Web Viewer, and other steps with multiple calculation slots silently bind a calculation to the wrong internal slot when elements are in the wrong order. The script appears to work. The calculation runs in the wrong context.

**Element ordering.** Several steps require child elements in
