helpers_increment_counter

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

Without annotations, the description bears full responsibility for disclosing behavioral traits. It states 'increment' but does not specify the increment amount, side effects, or that it requires a counter entity type. The mutation behavior is implied but lacks detail.

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 concise (one sentence of four words), which is appropriate for a simple tool but omits necessary details about the parameter and behavior. It is front-loaded but incomplete.

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 simplicity, the description could still explain the effect (e.g., increments by 1) and expected entity type. The presence of an output schema (not shown) does not reduce the need for parameter and behavioral 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?

The input schema has 0% description coverage and a single parameter 'entity_id' with no description. The tool description adds no meaning about what entity_id should reference or its format, leaving the agent to infer from context.

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 uses a specific verb 'increment' and resource 'counter helper', clearly indicating the action and target. It distinguishes itself from sibling tools like helpers_reset_counter or helpers_set_input_* by implying an additive operation.

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 this tool versus alternatives such as resetting or setting the counter. The description does not mention prerequisites, typical use cases, or conditions for invocation.

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