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

Annotations already establish that this is a non-read-only, non-destructive, non-idempotent creation operation. The description adds useful behavioral details—one-hour expiry, signed-in scope, no Parser credits, and a fallback on blocked PUT—but remains vague about what the returned link is, session lifetime after creation, and auth requirements beyond 'signed-in.'

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 short and front-loads the core action, but several sentences are cryptic fragments ('No Parser credits', 'Blocked PUT returns to an available panel') that reduce clarity rather than earning their place cleanly.

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 one-parameter creation tool with annotations and no output schema, the description covers the main purpose and some operational constraints. It is still incomplete because it does not explain how this differs from sibling upload-link tools or what the caller receives.

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?

There is one optional parameter and schema description coverage is 100%, so the schema already explains folderId and its behavior. The description adds no additional meaning about that parameter, which is acceptable at the baseline when schema coverage is complete.

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 and resource: 'Create a one-hour signed-in batch-upload link.' It is clear what the tool produces, but it does not distinguish this from siblings such as clm_create_upload_url or clm_create_type_generation_upload_url.

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 a partial when-to-use constraint: 'Claude chat: only if panel unavailable/failed and byte transfer cannot work.' However, this guidance is cryptic and does not explain when to choose this tool over the related upload URL tools or clm_import_files.

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