app.file_save

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

With no annotations, the description provides basic behavioral insight: it saves the current file, and for unsaved files it requires an absolute path. However, it lacks details on overwrite behavior, error handling, synchronous nature, or any side effects.

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

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

The description is a single sentence of 15 words, front-loaded with the primary action, and contains no unnecessary words. Every part is purposeful.

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

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

The description covers the core functionality but omits edge cases like what happens if the file is already saved (overwrites) or if a path is provided for an already saved file. For a simple tool it is adequate, but more detail would help an agent handle every scenario.

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

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

The schema description coverage is 0%, so the description must add meaning. It explains that the path is used only when saving an unsaved file, which goes beyond the parameter title. However, it does not specify path format (e.g., file included, extension requirements), leaving some ambiguity.

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

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

The description clearly states the verb 'save' and the resource 'current file', and covers the special case of unsaved files needing an absolute path. Among siblings like app.file_save_as and app.file_save_copy, this tool is distinct for saving the current file to its existing or specified path.

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

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

The description implies when to use: for saving the current file, optionally supplying a path for unsaved files. Although it does not explicitly state when not to use it or list alternatives, the context from sibling tools makes the distinction clear.

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