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

Beyond the annotations, it discloses that the output is a .txt download link valid for one hour, which is a significant behavioral detail. It does not claim to be read-only, so there is no conflict with readOnlyHint=false, though it could state side effects more explicitly.

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 purpose and output behavior are front-loaded in two crisp sentences. The trailing 'Pro.' is an unnecessary fragment that adds no operational value, preventing a 5.

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 single-parameter tool with no output schema, the description covers what is returned, the document contents, and link expiration. It would be more complete with an explicit statement about whether render state is modified, but the essential calling context is present.

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 already fully describes the only parameter with an example and the id-or-title resolution rule. The description adds no additional parameter semantics, so the high-coverage baseline of 3 applies.

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 the precise verb 'Render', a single change order, and the plain-text approval document format, listing its contents. This clearly distinguishes it from change_order_get (raw data) and change_order_invoice_payload (invoice).

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 phrase 'for the client to approve' establishes when to use it, and the output description makes it distinct from retrieving or listing change orders. It does not explicitly name sibling alternatives or exclusions, but the context is clear enough for selection.

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