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

With no annotations, the description carries the full burden and does disclose the input-format contract (base64) and a hard format restriction (no legacy .doc). It does not cover auth requirements, file-size limits, overwrite/duplicate-name behavior, or what the conversion produces, which are meaningful gaps for an unannotated mutation tool.

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?

Three short sentences, front-loaded with the core action, then the encoding requirement, then the format caveat. No filler and every sentence carries an actionable constraint.

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?

For a simple two-parameter ingestion tool with no annotations and no output schema, the description covers the critical input pitfalls (.docx only, base64) but omits filename semantics and any indication of what is returned (e.g., a template identifier needed for follow-up calls), which matters since no output schema exists.

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?

Schema coverage is 0%, so the schema itself documents neither parameter. The description compensates for fileData by specifying base64 encoding, but says nothing about filename (extension handling, uniqueness, whether it drives the template name), leaving one of two parameters semantically underspecified.

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?

States a specific verb pair (upload and convert) plus the resource and source format (.docx to a template), so an agent immediately knows this ingests a document rather than authoring one. It implicitly separates itself from template_create/template_update, though it never names those siblings explicitly.

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 preconditions for input are clear (base64 encoding required, .docx only, .doc rejected), which is genuine usage guidance. However, it gives no comparative guidance on when to call template_upload versus template_create or template_update, leaving the agent to infer that this is the file-ingestion path.

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