get_pixel_events

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

With no annotations, the description carries full burden. It discloses the time window (last 24 hours) and output breakdown (by event type and hourly counts). It does not mention side effects or permissions, but for a read operation this is acceptable. The description is transparent enough for the agent.

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 plus a parameter line. It front-loads the purpose with no wasted words. Ideal for quick understanding.

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 (1 param, no output schema), the description covers the purpose and parameter. However, it omits details on the response structure (e.g., format of hourly counts, event types). Since there is no output schema, more description of output would be beneficial. Adequate but not fully complete.

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 has 0% description coverage; the parameter only has a title. The description adds minimal value by noting pixel_id is a 'numeric string', but does not compensate for the lack of schema descriptions. The param description is insufficient.

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 gets events received by a pixel in the last 24 hours, broken down by event type and hourly counts. This specific verb+resource+scope distinguishes it from siblings like get_pixel_info or get_event_stats.

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 on when to use this tool versus alternatives. It does not mention exclusions, prerequisites, or other context. The sibling list is provided externally but the description itself lacks usage direction.

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