Delete stored follow-up reminders

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

With no annotations provided, the description must disclose behavioral traits. It explains that reminders are removed from the local store and optionally removes the Gmail label when no reminders remain. However, it does not clarify whether operations are irreversible, affect server data, or require specific permissions, leaving some behavioral gaps.

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 brief (two sentences) and front-loads the primary action. It efficiently conveys key usage patterns without extraneous details. A slightly more structured format (e.g., bullet points) could improve readability, but it is concise enough to be quickly parsed.

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 12 parameters, no output schema, and no annotations, the description covers the main functionality but lacks details on return values, error handling, or behavior when no reminders match. It adequately describes the tool's primary purpose but leaves some contextual gaps for complex usage scenarios.

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 adds critical meaning. It explains the purpose of eight key parameters: 'reminderIds', 'messageId', 'messageHeaderId', 'sourceThreadId', 'followUpChainId', 'cancelChain', 'deleteAll', and 'confirm'. It describes special behaviors like chain cancellation and bulk deletion. However, it omits 'statuses', 'accountAlias', 'chatScope', and 'removeGmailLabel' (implied but not detailed), so not all parameters are fully covered.

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 tool removes follow-up reminders from the local store, with a specific verb ('Remove') and resource ('follow-up reminder(s)'). It also mentions an optional Gmail label removal. The name 'multi_gmail_followup_cleanup' distinguishes it from sibling 'followup_cleanup', and the description implies multi-account support via the 'accountAlias' parameter.

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 lists ways to identify reminders and special options like 'cancelChain' and 'deleteAll' with 'confirm', providing some usage guidance. However, it does not explicitly compare to sibling tools (e.g., 'multi_gmail_followup_trigger', 'multi_gmail_followup_due') or state when not to use this tool, limiting its usefulness for choosing the right tool.

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