update_shared_link

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

The description mentions a side effect ('changes public link behavior immediately') but no annotations exist. It lacks disclosure on authorization needs or other behavioral traits, leaving some gaps.

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 concise and well-structured with a clear purpose, side effect note, and formatted Args/Returns sections. No unnecessary sentences.

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?

Given the output schema exists, description doesn't need to detail returns. It covers all 6 parameters, required field, and behavior, making it fully complete 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?

With 0% schema description coverage, the description fully compensates by explaining each parameter, including edge cases like empty string clearing values and removing expiry, adding significant meaning 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 clearly states it updates a shared link's permissions or expiry, using specific verb and resource. It distinguishes from related tools like create_shared_link and delete_shared_link.

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 description explains when to use the tool ('to tighten/loosen access or set an expiration date') but does not explicitly state when not to use it or provide alternatives, though context from sibling tools implies those.

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