create_tag

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

With no annotations, the description carries the full burden. It does contribute one valuable fact — the `tags:manage` permission requirement — but says nothing about duplicate-name behavior, whether the operation is idempotent, or what the response contains. The 'POST /api/v1/tags' line and the 'Tags: Tags' line are raw spec artifacts that add no behavioral insight.

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 text is short, but it is not well-curated: the bare endpoint path and the trailing 'Tags: Tags' label are noise, and the permission note is buried rather than front-loaded. The useful content is one sentence's worth.

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 one-parameter creation tool with no output schema, the definition covers purpose and authorization, which is most of what matters. It still leaves open whether the tag is global or workspace-scoped and how a duplicate name is handled, which an agent would want before calling.

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 coverage is 100% and the single `name` parameter is already fully documented in the schema as non-empty, so the description adds nothing here. Baseline 3 applies when the schema does the heavy lifting.

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?

"Create Tag" states a specific verb and resource, so the agent knows immediately this creates a new tag. There is no differentiation from siblings such as update_tag or delete_tag beyond the name itself, but the core 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?

The description never says when to use this versus update_tag or overview_tag_distribution, nor does it mention preconditions such as checking whether the tag already exists. Usage must be inferred entirely from the name.

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