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

With no annotations, the description only minimally discloses behavior (read-only list with status), lacking details on permissions, side effects, or output format.

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?

Single sentence front-loading verb and resource, zero filler words, and perfectly scaled for the tool's simplicity.

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?

For a zero-parameter list tool with an output schema, the description covers the essential purpose. It could clarify 'sharkd status' values or edge cases but is largely 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?

No parameters exist, and schema coverage is 100% as defined. The description adds value by stating the output includes 'sharkd status', which exceeds the baseline of 4 for zero-parameter tools.

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 specifies the action ('List') and the target ('every loaded PCAP') with additional qualifier ('with its current sharkd status'), making it distinct from siblings like load_pcap and unload_pcap.

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 implies usage for viewing all loaded PCAPs, but does not explicitly state when to use it over alternatives (e.g., pcap_summary for details on a single PCAP) or mention prerequisites.

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