Update release asset link

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

Annotations already indicate readOnlyHint=false and destructiveHint=false. The description adds no behavioral detail such as whether the update replaces the entire asset link or only provided fields, whether the link must already exist, or any side effects on the release. It simply restates the mutation implied by the annotations.

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 a single, front-loaded sentence with no filler. It uses the specific verb 'Update' and the resource 'external asset link', which is exactly as concise as possible while remaining clear.

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 tool with 7 parameters (5 required) and minimal schema descriptions, the description is too thin. It does not explain how to obtain link_id, whether the update is partial or full, or the relationship between url and direct_asset_path. The output schema exists, so return values are covered, but the invocation context is under-specified.

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 only 14%, with only 'project' described. The description does not explain any of the 7 parameters, especially the meaning of 'link_id', the distinction between 'url' and 'direct_asset_path', or the semantics of 'link_type'. It fails to compensate for the sparse schema documentation.

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 the action ('Update'), the resource ('external asset link'), and the scope ('attached to a GitLab release'). This distinguishes it from sibling tools like create_release_asset_link and delete_release_asset_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 provides no guidance on when to use this tool vs. alternatives. It does not mention using create_release_asset_link for new links, delete_release_asset_link for removal, or list_release_asset_links for finding the link_id. No prerequisites or exclusions are given.

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