Create release

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

Annotations already declare readOnlyHint=false, destructiveHint=false, idempotentHint=false, and openWorldHint=true. The description adds the behavior of optional tag creation, but does not disclose side effects or error conditions. It does not contradict 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 two sentences with no fluff, front-loading the core action and a key optional behavior. Every word earns its place.

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 is complex with 8 parameters, nested objects, and an output schema. The description is too terse to guide an agent on how to use it, especially since parameter coverage is low. It does not mention assets, milestones, or other important options.

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 13%. The description adds minimal insight by mentioning 'tag from a ref', which hints at tag_name and ref parameters, but leaves most of the 8 parameters (name, description, assets, milestones, released_at) completely unexplained.

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 verb 'Create' and resource 'GitLab release', and adds the key nuance of optionally creating its tag from a ref. This distinguishes it from related tools like create_tag and update_release.

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 gives the core purpose and implies when to use it (when creating a release), and hints at the alternative of only creating a tag. However, it does not explicitly state when not to use it or compare it to alternatives like create_tag.

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