htb_start_challenge

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

No annotations provided. Description only states it starts a container, but lacks disclosure of side effects, permissions, error handling, or return behavior. For a mutation tool, more transparency is needed.

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, 12 words, front-loaded with action. No extraneous content. Concise, though could benefit from additional structure for completeness.

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 simplicity (1 param, no output schema), description is minimally adequate. Tells basic function and condition, but lacks detail on return values, errors, or preconditions.

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?

Schema coverage is 0% with no parameter description. Description adds 'by challenge id' but does not clarify where to get the id or format. Insufficient compensation.

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?

Description uses specific verb 'start' and resource 'challenge container' with condition 'when the challenge supports containers'. This distinguishes it from siblings like htb_start_container, which may be for generic containers. Clear purpose.

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?

Implies usage when wanting to start a container for a challenge that supports containers. Provides a condition but no explicit when-not-to-use or alternatives. Moderate guidance.

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