resubscribeContact

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

No annotations are present, and the description merely states the action without explaining behavioral traits—such as whether it overwrites subscription status or requires a prior unsubscribed state. This is insufficient for an agent to understand side effects.

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 extremely short (two words plus context), which is concise but lacks structure. It could be more informative without sacrificing brevity.

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 simple input schema and no output schema, the description should explain the action's effect, prerequisites, and possible return values. It only states 'Resubscribe contact in mailmodo', leaving many gaps.

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 schema defines one parameter 'email' (required, string) with 0% documentation coverage in the schema description. The tool description adds no extra meaning—no format, example, or constraint beyond the schema field name.

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 'Resubscribe contact in mailmodo', clearly indicating the action (resubscribe) and the resource (contact). However, it does not differentiate from sibling tools like 'unsubscribeContact' or 'addContactToList'.

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 provided on when to use resubscribeContact versus alternatives such as unsubscribeContact or addBulkContactToList. The description lacks context for appropriate usage.

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