Create release

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

Annotations already indicate readOnlyHint=false and destructiveHint=false, so the agent knows it is a mutation but not destructive. The description adds nothing beyond that—it doesn't disclose that the release is associated with an existing tag, that the tag could be auto-created via the 'ref' parameter, or that the operation is essentially a create. Minimal added value beyond 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 wasted words. It is highly concise and easy to parse, though this comes at the expense of completeness (captured in other dimensions).

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 tool has 6 parameters, no output schema, and simple annotations. The description is far too brief to be contextually complete: it doesn't mention that the release is tied to a tag, how the 'ref' parameter can create missing tags, any permission requirements, or what the response contains. It also fails to differentiate from sibling tools like gitlab_list_releases, making the overall context insufficient.

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 33% (only 'ref' and 'project_id' have descriptions). The description does not compensate: it fails to explain that 'tag_name' is required, or the meaning of 'name', 'description', or 'milestones'. The phrase 'for a tag' provides only a vague clue about tag_name. This is insufficient for a 6-parameter tool with low schema coverage.

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 a specific verb+resource: 'Publishes a release for a tag.' It distinguishes this from sibling operations like listing releases (gitlab_list_releases) or managing tags (gitlab_tag_action), making the tool's purpose unmistakable.

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?

No guidance is provided on when to use this tool versus alternatives. It does not mention prerequisites (e.g., tag existence), alternatives like gitlab_list_releases for reading releases, or exclusions. The agent is left without context for selecting this tool.

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