ctf_sendline

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

No annotations are provided, and the description only mentions auto-appending newlines and returning a confirmation. It does not disclose potential side effects, blocking behavior, error handling, or required permissions. For a tool with no annotation coverage, this is insufficient.

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 very concise and front-loaded, with only two sentences. It wastes no words but could benefit from slightly more detail without becoming verbose.

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 (one parameter, likely simple output), the description is adequate but lacks behavioral and usage context. The presence of an output schema reduces the need to explain return values, but the description could still be more 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 no description (0% coverage), so the description must compensate. It clarifies that the 'line' parameter is text and a line to send, adding basic meaning. However, this is minimal, and further details (e.g., encoding, length limits) would improve the score.

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 sends a line of data to a CTF program with auto-appended newline. It is specific about the resource (line) and action (send), and the name contrasts with sibling tools like ctf_send (likely raw) and ctf_recv (receive). However, it does not explicitly differentiate from ctf_send, which would elevate to a 5.

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 such as ctf_send or ctf_recv. The description lacks context about prerequisites or conditions for use.

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