backup_scene

Back up a Godot scene file before editing, storing timestamped copies in .scene_backups/. Use the returned path to restore if needed.

Instructions

[OPTION B - Part 1] Create a timestamped backup of a scene file (.tscn) BEFORE making edits. Stores backups in /.scene_backups/. Always call this before using batch_add_nodes, set_node_properties, or any destructive scene mutations. Returns the backup file path to use with restore_scene_backup if needed.

Tool call template

TDQS

A4.7/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations provided, so the description carries full burden. It states the backup is timestamped, stored in a specific directory, and returns a file path. It doesn't mention error handling or permissions, but for a backup tool this is adequate.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Four concise sentences, each adding essential information: purpose, storage location, usage directive, and return value. No redundant language.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple tool with 2 parameters and no output schema, the description covers purpose, timing, storage, sibling relation, and return value. It is complete and leaves no major gaps.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema already has clear descriptions for both parameters (100% coverage). The description adds value by explaining the backup storage location, which implies the path structure. This is helpful but not critical.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the verb 'Create' and the resource 'backup of a scene file (.tscn)'. It specifies the context of being called before edits and distinguishes from sibling tools like restore_scene_backup and mutation tools by naming them explicitly.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Explicit guidance on when to use: 'Always call this before using batch_add_nodes, set_node_properties, or any destructive scene mutations.' It also mentions the return path for use with restore_scene_backup, providing a clear usage pattern.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
