pine_update_call_reminder

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

With no annotations, the description must disclose behavioral traits. It only states 'update' and recommends confirmation, but does not explain side effects (e.g., notifications sent, permissions required, reversibility). 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 concise with a front-loaded purpose sentence followed by a clear parameter list. No unnecessary information is included, making it efficient for an agent to parse.

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 tool's complexity (4 required params, output schema present), the description covers the core purpose and parameter meanings. However, it lacks behavioral context (e.g., error handling, state changes) that would be expected without annotations.

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?

The Args section provides meaningful descriptions for all four parameters, compensating for the 0% schema coverage. It clarifies purpose (e.g., 'session with the scheduled call') and format (ISO 8601 for time), though more detail on expected values could improve.

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 updates a scheduled call reminder, using a specific verb and resource. It distinguishes from sibling tools like pine_session_create or pine_send_message by focusing on reminder updates.

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 advises to 'confirm timing with the user first,' providing a basic usage guideline. However, it lacks explicit when-not-to-use or alternative tool suggestions, which limits its utility for selection.

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