rename_tag

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

Discloses side effect (automatic update of tasks) and auth requirement (V2) and category. However, no annotations are provided, so the description carries full burden. It lacks details on reversibility, naming constraints, or error conditions.

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?

Very concise, no unnecessary words. The action is front-loaded. The Args section is arguably redundant but not harmful.

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?

Provides key side effect and auth info, but lacks details on return value, error handling, naming rules. With no output schema, more context would be helpful. However, it covers the essential purpose adequately.

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 0%, and the description adds minimal parameter information: 'old_name: Current tag name. new_name: New tag name.' This basically replicates the schema titles with slight rewording, not adding significant meaning beyond what a user could infer.

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 'rename a tag' and adds important context 'All tasks using it are updated automatically.' This distinguishes it from related tools like merge_tags and update_tag.

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?

Only lists related tools but provides no guidance on when to use rename_tag versus alternatives like update_tag or merge_tags. There is no 'when not to use' or explicit context.

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