update_task_tag

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

With no annotations provided, the description carries the full behavioral burden and does so excellently. It discloses that only the tag changes, that tag=None or an empty string clears the tag, and that subtasks are untouched by the call.

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 well-structured and front-loaded with the core action, then examples, then exclusions and caveats. It is detailed but every sentence adds meaningful information; nothing is redundant.

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 two-parameter tool with an output schema, the description is complete. It covers what the tool changes, what it preserves, when to use it, how to clear a tag, and an important subtask side-effect caveat.

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 0%, so the description must compensate. It explains the tag parameter's semantics well, including the clearing behavior, and gives concrete task_id examples. It does not formally define task_id, but the integer schema plus examples make it sufficiently clear.

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?

States a specific verb and resource: 'Change the tag on an existing logged task.' It also explicitly lists what is NOT altered (log_date, status, description, ID), which cleanly distinguishes it from siblings like update_task_status and update_task_due_date.

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?

Gives clear when-to-use guidance with concrete user examples ('tag #12 as infra', 'remove the tag from #7'). It also tells the agent what NOT to do ('do NOT delete and re-log the task') and explains why, making the invocation context unambiguous.

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