Rename Tag

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

No annotations are provided, so the description carries the burden of disclosing side effects. It explicitly states 'All tasks with this tag will be updated,' which is a key behavioral trait beyond the mere rename. It does not mention failure modes or irreversibility, but the disclosed cascading update adds meaningful transparency.

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 two concise sentences, front-loaded with the primary action. Every sentence adds value—the second sentence clarifies the side effect. No redundant or filler content.

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?

The tool is simple (two string parameters, no output schema), and the description covers the core operation and its effect. It avoids over-explaining return values since none are expected. Minor omissions such as error handling or prerequisite checks, but acceptable for the tool's simplicity.

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?

Input schema covers both parameters (old_name and new_name) with descriptions, so schema coverage is 100%. The description adds no additional parameter-level meaning beyond what the schema already provides, justifying the baseline score of 3.

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 uses a specific verb+resource: 'Rename an existing tag.' It clearly distinguishes this from sibling operations like create, delete, merge, and get tags by stating the action and its scope. The added effect 'All tasks with this tag will be updated' reinforces the purpose.

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 when to use the tool (when a tag's name needs changing) but does not explicitly contrast it with alternatives like merge_tags or create_tag. It gives no when-not-to-use guidance or edge cases, so usage context is only implicit.

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