pentest_ctf_init

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

No annotations are supplied, so the description carries the full burden. It usefully discloses that the authorization statement is pre-filled and that CTF-platform handoff counts as authorization, but it omits write semantics that matter for a file-creating tool: overwrite behavior if the path exists, permission requirements, and what the 48-hour default is meant to represent.

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?

Two short sentences with zero filler, and the core action plus its return value are front-loaded before the authorization rationale and the follow-up tool. Every clause earns its place.

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?

The description adequately covers purpose, authorization rationale, and the next step for a creation tool with no output schema. However, with no annotations and 0% parameter documentation, an agent still cannot tell what hours or engagement_id do or whether an existing file will be clobbered, which is a material gap for a mutating tool.

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 description coverage is 0% across four parameters, so the description must compensate and largely does not. 'Target' and 'path' are only obliquely implied by 'CTF challenge box' and 'return its path'; 'hours' and 'engagement_id' are never mentioned at all, leaving two of four parameters with no meaning anywhere in the definition.

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?

States a specific verb and resource ('Create a ready-made engagement file'), scopes it to CTF challenge boxes, and notes it returns the path. It also names the natural follow-up tool, pentest_load_engagement, so an agent can place it in the workflow without opening a sibling schema.

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?

Gives a clear activation condition ('a CTF platform handing you the target is the authorization') and the explicit next step ('Load the result with pentest_load_engagement'). It does not say what to do for non-CTF engagements or whether an existing file is reused, but the when-to-use guidance is otherwise concrete.

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