Update Reminder

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

Annotations lack behavioral hints (e.g., readOnlyHint, destructiveHint). Description only states 'update', implying mutation, but no disclosure of side effects, permissions, or error conditions. This is insufficient for a mutation tool.

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 very short, which is concise but lacks substance. It could be expanded with key details without becoming verbose. It is not optimized for quick scanning.

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 7 parameters and an output schema, the description is far too minimal. It does not explain the effect of clear flags, the meaning of priority values, or the return format. The tool is incomplete in context.

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%, and the description provides no additional meaning for any of the 7 parameters. Parameters like clear_due and clear_notes are unexplained, and the description adds no value beyond the schema names.

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?

Description clearly states the action (update) and resource (reminder) and specifies the identifier (canonical id). It distinguishes from siblings like reminders_complete and reminders_create. However, it does not elaborate on what aspects can be updated.

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?

No guidance on when to use this tool versus alternatives like reminders_complete or reminders_create. No mention of prerequisites or conditions for use.

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