GitLab Execute Action

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

The annotations already indicate destructiveHint=true, readOnlyHint=false, and idempotentHint=false. The description adds meaningful behavioral context beyond those hints by specifying that destructive actions require top-level confirm=true, which is essential for safe invocation of this dynamic executor.

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 three concise sentences with no wasted words. It front-loads the core purpose, follows with the most critical invocation constraints, and ends with a clear routing instruction for the sibling tool.

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?

Given that an output schema exists and the annotations cover read-only, idempotency, and destructive behavior, the description provides the remaining key context: how to invoke the action, when confirmation is required, and when to defer to gitlab_find_action. Nothing essential is missing for an agent to use this tool correctly.

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 schema already documents all three parameters well. The description reinforces the top-level confirm rule and the object-shaped params requirement, but it mostly restates what the schema already provides, so the added semantic value is limited.

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 action: 'Execute one GitLab catalog action by canonical ID or alias.' This clearly identifies what the tool does and distinguishes it from the sibling tool gitlab_find_action, which is about discovery rather than execution.

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 explicit usage routing: 'Use find first only when action or params are unclear.' It also provides concrete invocation guidance, such as always passing params as an object and using top-level confirm=true for destructive actions, which helps the agent call it correctly.

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