create_tagging

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

No annotations are provided, so the description carries full burden. It mentions 'Qiita Team only' (a platform restriction) and 'Optionally specify versions' (a behavioral nuance), but fails to disclose critical traits: whether this is a mutation (implied by 'Add'), permission requirements, error handling (e.g., duplicate tags), or response format. For a mutation tool with zero annotation coverage, 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?

The description is a single, efficient sentence with zero waste. It front-loads the core purpose ('Add a tag to an item') and appends key constraints ('Qiita Team only') and optional features ('Optionally specify versions') concisely.

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 a mutation tool with 3 parameters, 100% schema coverage, but no annotations or output schema, the description is moderately complete. It covers the basic action and platform restriction but lacks details on behavioral outcomes (e.g., what happens on success/failure, tag limits) and doesn't compensate for the missing output schema. Adequate but with clear gaps for a write operation.

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%, with clear parameter descriptions in the schema (item_id, name, versions). The description adds minimal value beyond the schema—it reiterates that versions are optional but doesn't explain semantics like tag naming rules, version format implications, or item_id sourcing. Baseline 3 is appropriate as 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?

The description clearly states the action ('Add a tag') and target ('to an item'), with the specific constraint 'Qiita Team only' indicating platform scope. It distinguishes from sibling 'delete_tagging' by being the creation counterpart, though it doesn't explicitly differentiate from other tag-related tools like 'follow_tag' or 'list_tags'.

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 usage when tagging items in Qiita Team, with optional version specification. However, it lacks explicit guidance on when to use this versus alternatives like 'update_item' (which might handle tags differently) or prerequisites (e.g., authentication, item existence). The 'Qiita Team only' note provides some context but no detailed exclusions.

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