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

With no annotations provided, the description carries the full burden of behavioral disclosure. It mentions that a 'progress table will be displayed,' hinting at output behavior, but lacks details on permissions, error handling, or mutation effects (e.g., whether updates are reversible). This is a significant gap for a mutation tool with zero annotation coverage.

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 front-loaded with the core purpose and constraint in the first sentence, followed by output behavior. It uses two sentences efficiently with minimal waste, though it could be slightly more structured by separating constraints from output details.

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 the complexity of a mutation tool with 4 parameters, 0% schema coverage, no annotations, and no output schema, the description is incomplete. It covers some aspects (purpose, constraint, output hint) but misses critical details like parameter meanings, error scenarios, and full behavioral context, making it inadequate for reliable agent use.

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 for undocumented parameters. It mentions 'title and/or description,' which maps to two of the four parameters (title, description), but doesn't explain 'requestId' or 'taskId' (the required ones). This partial coverage leaves key parameters unexplained, failing to fully address the schema 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 action ('Update') and resource ('an existing task's title and/or description'), making the purpose evident. However, it doesn't explicitly differentiate this from sibling tools like 'update_note' or 'update_subtask', which share similar naming patterns but target different resources.

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 provides some usage context by stating 'Only uncompleted tasks can be updated,' which implies a constraint on when to use this tool. However, it doesn't offer explicit guidance on when to choose this over alternatives like 'mark_task_done' or 'delete_task,' nor does it mention prerequisites beyond the constraint.

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