update_share_link

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

No annotations are provided, so the description must fully disclose behavior. It only says 'Update a share link' without mentioning side effects, authorization needs, or constraints (e.g., immutability of certain fields). This is minimal disclosure beyond the verb.

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 extremely concise with a front-loaded purpose ('Update a share link') followed by a usage tip and a well-structured bullet list of parameters. Every sentence adds value, and no words are wasted.

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?

The description covers the basic purpose and parameters but lacks information on error cases, prerequisites (e.g., link must exist), and side effects. Given that an output schema exists, the return value is not needed, but the description could be more complete for a mutation tool.

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 0%, so the description bears full responsibility. It clearly explains each parameter (e.g., 'New expiration timestamp (ISO 8601)') in the Args list, adding meaning beyond the raw schema. However, it could include more constraints (e.g., max_uses must be positive).

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 'Update a share link', which is a specific verb (update) and resource (share link). It distinctly differentiates from sibling tools such as create_share_link, delete_share_link, get_share_link, and list_share_links.

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 includes 'Only provide the fields you want to change', which gives a clear partial-update usage tip. However, it does not explicitly state when to use this tool versus alternatives (e.g., create_share_link for new links), though the context of sibling tools makes it implicit.

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