pwntools_tube_recv

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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is clear. The description adds 'from an active tube,' which is implicit but not in annotations. No contradictions exist. Scoring 3 as description adds minimal value beyond annotations.

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, succinct sentence of six words. It is front-loaded with the core action and contains no extraneous information. Every word earns its place, achieving maximum conciseness.

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, annotations covering safety, and the presence of an output schema, the description is mostly complete. However, it lacks guidance on when to use this tool versus sibling recv tools (recvline, recvuntil), which would improve completeness. Score 4.

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 provides descriptions for all parameters (nbytes, timeout, tube_id), so schema_description_coverage is effectively high. Per scoring guidelines, baseline is 3 even with no param info in description. The description adds no additional meaning, so score remains 3.

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 'Receive data from an active tube' clearly states the verb (receive) and resource (data from tube). However, it does not differentiate from sibling tools like pwntools_tube_recvline or pwntools_tube_recvuntil, which have more specific purposes. A score of 4 reflects clear purpose but lack of sibling distinction.

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 pwntools_tube_recvline, pwntools_tube_recvuntil, or other tube operations. The description lacks usage context, making it difficult for an agent to select it appropriately.

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