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

Annotations already declare this is a non-read-only, open-world, non-idempotent, non-destructive operation. The description adds the owner/admin permission requirement and the visible effect of linking, but it does not disclose what happens on repeated calls or whether existing links are replaced, which matters for a non-idempotent mutation.

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 that states the required role, the action, and the result. Every clause contributes useful information with no filler.

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 two-parameter mutation with no output schema and 0% parameter description coverage, the description should explain how to reference the space and feed and what to expect after linking. It omits both, so an agent must infer valid parameter formats and the result of the operation.

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 must carry the burden of explaining the two required parameters. It only gives the conceptual roles of 'space' and 'feed' without indicating whether either expects an ID, slug, name, or URL, leaving the agent unable to determine valid values.

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 states a specific verb and resource: link a space to a Trana feed, and it clarifies the effect that questions and decisions will also appear there. It does not compare itself to sibling tools like trana_feed or space_set, so it is clear but lacks explicit sibling differentiation.

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 'Owner or admin' prefix gives a useful prerequisite, but the description does not explain when to choose this tool over related tools, nor does it state any when-not conditions. Usage is implied rather than explicitly guided.

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