C2.4/5.0
Behavior2/5

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

No annotations are provided, so the description carries the full burden, yet it never says whether an existing file at that path is overwritten, whether the format is inferred from the extension, or whether the current document state is modified. Only the bare fact that saving targets a path is conveyed.

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

Conciseness3/5

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

Five words, front-loaded and waste-free, but the brevity reflects under-specification rather than tightness; there is room to add essential detail without bloat.

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

Completeness2/5

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

For a write/mutation tool with no annotations, no output schema, and a single undocumented parameter, the description omits nearly everything an agent needs: overwrite behavior, format selection, return value, and eligibility relative to app.save_document.

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

Parameters2/5

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

Schema coverage is 0% for the single 'path' parameter. The phrase 'specific path' gives almost nothing beyond the schema — no indication of whether it is a file path vs directory, which extensions/formats are supported, or whether relative paths are accepted.

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

Purpose3/5

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

States the verb 'Save' and that a path is involved, which hints at a save-as (write to a new location) operation. However it does not distinguish this from the sibling app.save_document, so an agent cannot tell which to pick without guessing at hidden semantics.

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

Usage Guidelines2/5

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

No when-to-use guidance, no mention of app.save_document or app.open_document as alternatives, and no prerequisites (e.g., must a document be open first?). Usage can only be inferred from the name.

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