list_flags

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

With no annotations provided, the description carries the behavioral disclosure burden. It meaningfully discloses that the vault never returns plaintext and that only redacted previews are provided, which is important for an agent's expectations about output sensitivity. It does not mention permissions or pagination, but for a simple list operation this is useful transparency.

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?

A single sentence with no filler, front-loading the action ('List flags on a challenge') and then adding the key behavioral caveat about redaction. Every word 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?

For a tool with one parameter and no output schema, the description covers the operation, the scoping resource, and the nature of the returned data. It is slightly light on explicit parameter semantics and any error or pagination behavior, but those are minor gaps for this simple 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 property descriptions are 0%, so the description must compensate. It only says 'on a challenge', which implies challenge_id identifies the target challenge, but it does not explicitly explain the parameter's role, format, or requiredness. The schema already defines the UUID format and required flag, and the single self-explanatory parameter makes this minimally adequate.

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: 'List flags on a challenge', and further clarifies the output is redacted previews. This clearly differentiates it from sibling tools such as submit_flag_candidate (submission) and get_challenge (challenge detail retrieval).

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 the tool is used for listing flags on a challenge, but it provides no explicit guidance on when to choose this tool over alternatives, nor any exclusions or prerequisites. There is no reference to sibling tools or conditions that would make this tool the right choice.

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