create_tag

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

No annotations are provided, so the description carries full behavioral disclosure burden. 'タグを作成' only states the create action without revealing what happens on creation (duplicate handling, required permissions, relationship to tag_entry, or whether categories are validated). For a mutation tool with zero annotations, this is insufficient.

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?

A single concise sentence 'タグを作成' with zero waste. Perfectly efficient for stating the core action, though it sacrifices detail for brevity.

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 mutation tool with no annotations, no output schema, and limited sibling differentiation, the description is thin. It doesn't explain return values, error conditions, duplicate tag behavior, or the distinction between create_tag and the many related tag tools (tag_entry, untag_entry, list_tags). Given the tag ecosystem complexity, more context is warranted.

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 both name and category parameters have basic descriptions. The description adds 'タグを作成' which implies name is the tag being created, but doesn't clarify how category relates to the tag structure or whether it's optional in practice. Baseline 3 is appropriate given full schema coverage.

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 'タグを作成' (Create tag) uses a specific verb+resource combination that clearly indicates the tool creates a tag. However, it doesn't add any detail distinguishing it from siblings like tag_entry or untag_entry, which operate on tags differently. The purpose is clear but minimal.

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?

No when-to-use guidance is provided. The description doesn't clarify when to use create_tag versus list_tags, tag_entry, or untag_entry. For a tag management toolset, this lack of guidance leaves the agent guessing about which tag operation to invoke.

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