Get Namespace

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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the agent knows it's a safe read. The description adds the lookup method ('by ID or path') but does not mention any additional behavioral traits like authentication needs or rate limits. With strong annotations, the description provides adequate context.

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 sentence of 6 words, extremely concise and front-loaded. It contains no filler. However, it could include a bit more context without becoming verbose.

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 2 parameters, no output schema, and only 0% schema description coverage, the description is too sparse. It does not explain what a namespace is, what the return value contains, or how to choose between parameters. Additional context would improve usability.

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?

The schema has 0% description coverage, so the description must compensate. It mentions 'by ID or path', hinting at the two parameters, but does not explain the distinction between namespace_id and namespace_id_or_path, when to use each, or the expected format. The agent may be confused about which parameter to provide.

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 'Get namespace by ID or path' clearly states the verb (Get), resource (namespace), and lookup method. It distinguishes from siblings like gitlab_list_namespaces (which lists) and gitlab_verify_namespace (which verifies existence).

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 implies use when you have a namespace ID or path, but it does not explicitly state when not to use it or compare to alternatives. No guidance on choosing between the two parameters or when to prefer this over gitlab_get_project (which also uses namespace paths).

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