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

Annotations already disclose readOnlyHint=false, destructiveHint=false, idempotentHint=false and openWorldHint=false, so the safety/mutability profile is covered. The description adds the write-scope requirement, which is genuinely useful auth context the annotations do not carry, but it says nothing about side effects such as whether the template applies to new projects or how the optional structure/is_default fields behave.

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?

Two short sentences with zero filler; the action is front-loaded and the scope requirement follows immediately. Nothing is redundant or padded.

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 mutation tool with no output schema, the description covers the essentials (what it creates, the required scope) and annotations cover the safety profile. It is missing any note on what is returned or how the optional structure hierarchy is expected to be shaped, leaving a moderate gap for an agent building the payload.

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 description coverage is 100%, so all four parameters (name, structure, is_default, description) are already documented in the schema and the baseline is 3. The description contributes no additional meaning about parameter format or constraints beyond the schema.

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 states a specific verb (Create) and resource (project document folder template), which cleanly separates it from the delete/get/list/update siblings on the same resource. It does not, however, distinguish itself from adjacent creation tools like create_project_document, so it stops short of a 5.

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?

There is no guidance on when to use this tool versus list_/get_/update_/delete_project_document_folder_template, nor any context on when a template is preferable to creating documents directly. The only conditional content is the scope prerequisite, which is a permission note rather than usage selection guidance.

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