lc_preview_payload_upload_url

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

No annotations provided, so description carries full burden. It only says 'without uploading bytes', implying no side effects, but fails to disclose auth requirements, rate limits, or what the preview returns. Insufficient for safe decision-making.

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?

Single sentence, very concise, but lacks structure and important details. Conciseness is good, but under-specification harms utility.

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?

With no annotations, no output schema, and 0% schema coverage, description is severely incomplete. Does not cover return value, side effects, parameter meanings, or prerequisites. Inadequate for the tool's complexity.

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%, meaning description must compensate for three parameters (oid, name, token_ttl_seconds). Description provides no explanation of these parameters whatsoever, leaving the agent to guess their meaning.

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?

Description clearly states it previews a signed payload upload URL without uploading bytes. Verb 'Preview' and resource 'signed payload upload URL' are specific. Differentiates from actual upload tools by explicitly saying 'without uploading bytes', but doesn't distinguish from other preview tools.

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?

No guidance on when to use this tool versus alternatives like lc_get_payload_download_url or actual upload tools. No explicit context or exclusions provided.

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