create_tag

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

With no annotations provided, the description carries full burden for behavioral disclosure. It states the tool creates a tag, implying a write/mutation operation, but doesn't disclose any behavioral traits like permission requirements, whether duplicate tag names are allowed, what happens on success/failure, or if there are rate limits. The description is minimal and lacks crucial operational 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 extremely concise with just two sentences that are front-loaded and waste no words. Every part earns its place: the first sentence states the core purpose, the second adds important optional functionality. This is an excellent example of efficient communication.

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 this is a mutation tool (creates resources) with no annotations, no output schema, and 0% schema description coverage, the description is incomplete. It doesn't explain what happens after creation, what the response contains, error conditions, or any behavioral constraints. For a tool that modifies system state, this level of documentation is inadequate.

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?

With 0% schema description coverage for both parameters, the description must compensate but only partially does so. It mentions 'story_id' as optional for linking to a story, adding some semantic context, but provides no information about the 'name' parameter (required, type, constraints) or what format story_id should be. The description doesn't adequately cover the parameter semantics gap.

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 tool's purpose with a specific verb ('Create') and resource ('a tag'), making it immediately understandable. It distinguishes from sibling 'create_tag_and_add_to_story' by not automatically linking to a story, but doesn't explicitly differentiate from other creation tools like 'create_story' or 'create_component'.

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 context by mentioning 'Optionally link to a story via story_id,' suggesting this is for creating standalone tags that can be associated with stories. However, it doesn't provide explicit guidance on when to use this versus alternatives like 'create_tag_and_add_to_story' or when tag creation is appropriate versus using existing tags.

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