check_ics_feed

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

With no annotations provided, the description carries full burden for behavioral disclosure. It does not clarify whether the tool performs a read-only check, what happens if the subscription is invalid, or any side effects. The description is too brief to convey essential behavioral traits.

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 a single sentence, which is concise, but it omits necessary context. It earns its place but fails to convey enough information for an effective tool description.

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 presence of an output schema (not shown), the description need not detail return values, but it should clarify what 'subscription status' means, what possible statuses exist, and how this differs from other calendar checks. The description is incomplete for a tool with no parameters.

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 input schema has zero parameters, and schema description coverage is 100%, so the schema adds no constraints. The description correctly implies that no further input is needed. A baseline of 4 is appropriate given no parameters require elaboration.

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 states 'Check ICS calendar feed subscription status', which communicates a specific action (check status) on a resource (ICS feed subscription). However, it does not differentiate from the sibling tool 'save_ics_feed' or other calendar tools like 'check_calendar_connection'.

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 is given on when to use this tool versus alternatives such as 'save_ics_feed' or 'check_calendar_connection'. The description lacks context about prerequisites or situations where checking the ICS feed status is appropriate.

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