create_release

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It only says 'Create a new release' and does not mention important behaviors such as creating a new tag when tag_name does not exist, the relationship between ref and tag_name, authentication requirements, or side effects. For a mutating tool, this is a significant transparency gap.

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 short sentence with no wasted words and the core action is front-loaded. It is efficient, though it is arguably too terse for a tool with nine parameters and nested asset objects. Still, conciseness itself is handled well.

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?

This is a complex creation tool with nine parameters, nested assets, no output schema, and no annotations, yet the description provides almost no operational context. It omits the key behavior that a release can be created from a ref when the tag does not exist, and it does not clarify how the tool fits into the broader release lifecycle. The schema documents parameters well, but the description leaves important behavioral context uncovered.

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 100%, so the parameters are already well documented in the input schema. The description itself adds no parameter-level meaning beyond what the schema provides. This meets the baseline but does not exceed it.

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 and resource: 'Create a new release in a GitLab project.' It identifies the primary purpose and, combined with the tool name, distinguishes it from siblings like update_release, delete_release, get_release, and list_releases. It is not a tautology, but it is brief and does not explicitly contrast with these alternatives.

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 no guidance on when to use this tool versus alternatives such as update_release, create_release_evidence, or delete_release. There are no scenarios, prerequisites, or exclusions mentioned. Usage is only implicitly derivable from the tool name and the single-line description.

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