retrieve_tag

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

Annotations already declare readOnly, idempotent, non-destructive, and openWorld, so the description owes little on safety. Beyond the endpoint line, it adds only the garbled phrase 'Get attributes values to a specific tag,' giving no information about response contents, 404 handling, or permission requirements — a real gap given there is no output schema.

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?

Two short sentences with the verb+resource front-loaded, but the second sentence is grammatically garbled and semantically redundant, and the bracketed endpoint path restates routing information already implied by the name and schema.

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 simple read tool with rich annotations and full schema coverage, the description is adequate but thin. The absence of an output schema means some statement of what a tag object contains would have real value, and the garbled sentence fails to supply it.

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% and both parameters (tagId, x-trace-id) are fully documented in the schema. The description only echoes 'by id' and adds no format, range, or trace-id semantics, so the baseline of 3 applies.

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?

States a specific verb and resource ('Get specific tag by id') and the endpoint path reinforces single-resource retrieval, which implicitly separates it from retrieve_tag_list. It does not name siblings explicitly, but the purpose is unambiguous.

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?

There is no guidance on when to use this versus retrieve_tag_list or when to fetch a tag at all. The 'by id' qualifier hints that an identifier is required, but no prerequisites, failure conditions, or alternative routing are described.

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