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

Annotations already declare destructiveHint=true, idempotentHint=true, readOnlyHint=false and openWorldHint=false, so the safety profile is carried by structured data. The description adds no behavioral context beyond that: it doesn't say whether related statistics or historical data are preserved, what happens when no link exists, or what permissions are required. Given the lower bar set by annotations, this is thin.

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 or redundancy. It is efficient, though its brevity contributes to the gaps in guidance and parameter detail.

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 low-complexity two-parameter tool with rich annotations and no output schema, the description is minimally adequate. It leaves the agent without error/edge-case behavior (unlinking an already-absent link) and without format detail on the ID parameters, which the 0% schema coverage does not otherwise supply.

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%, so the description must carry parameter meaning; it does partially by mapping 'one Facebook campaign' to fb_campaign_id and 'one tracker campaign' to campaign_id, which is useful given the mismatched types (string vs integer). However it says nothing about accepted formats for the Facebook campaign ID (numeric vs prefixed) or the tracker campaign ID range.

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?

States a specific verb ("Remove the link") and the exact resource pair (one Facebook campaign and one tracker campaign), which makes it clearly the inverse of the sibling link_meta_campaign. It stops short of explicitly naming that sibling, so differentiation is inferred rather than stated.

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 contains no when-to-use, when-not-to-use, or alternative guidance. It never points to link_meta_campaign for creating links, nor mentions prerequisites such as the link existing or the workspace having Meta access. Usage is only inferable from the bare purpose statement.

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