Bulk update links

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

Annotations already declare destructiveHint=true, idempotentHint=false, readOnlyHint=false, and openWorldHint=true, so the safety profile is covered. The description adds the meaningful trait that all targeted links receive identical data and the 100-link ceiling, but it omits the confirm-required gating, whether unspecified fields are overwritten or left intact, and partial-failure behavior. Given the annotations carry the safety burden, a 3 is appropriate.

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?

A single, front-loaded sentence with no filler; the verb, limit, and scope arrive immediately. It is efficient, though one clause ('for the authenticated workspace') is near-redundant given the account parameter, keeping it just short of a 5.

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?

This is a destructive bulk mutation with 7 top-level parameters, nested data objects, three mutually exclusive body-delivery paths (payload, payload_file, inline flags), and a confirm requirement — yet the description is one sentence that never mentions any of this. With no output schema, the description should at least warn about the exclusivity rules and confirm gating; it does not.

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 86%, well above the 80% threshold, so the schema already documents the payload fields, linkIds/externalIds precedence, and confirm semantics in detail. The description adds no parameter-level meaning (no mention of linkIds vs externalIds, payload vs payload_file, or the confirm flag), so the baseline 3 applies.

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 gives a specific verb (bulk update), resource (links), and scope (up to 100 links, same data, authenticated workspace), which clearly separates it from the singular update_link and from bulk_create_links/bulk_delete_links. It stops short of explicitly naming a sibling or the alternative path an agent should consider, so it lands just below the top band.

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 phrase 'with the same data' implicitly signals the bulk-set semantics that distinguish this from per-link update tools, which is useful context. However, no explicit when-to-use/when-not guidance, no prerequisites, and no named alternative (e.g. upsert_link for mixed create/update) are given, so usage must be inferred.

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