Placeholders

Placeholders are string tokens in the form {{KeyName}} resolved by runtime context before operation execution.

Common Built-In Placeholders

• {{Game_Root}}: absolute module root path
• {{Project_Root}}: absolute repository root path

Module Placeholders

Module-specific placeholder keys come from config.toml placeholders tables.

Resolution Scope

Placeholder expansion applies to operation script paths, arguments, and nested operation payload values.

Resolution Timing

• Parent operation values are resolved before parent execution.
• onsuccess child operations resolve using latest runtime context at child execution time.

Good Practices

• Use descriptive placeholder names.
• Keep placeholders stable across operation revisions.
• Avoid hardcoding machine-specific absolute paths in operation files.
