agora_create_challenge

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

With no annotations, the description carries the full burden, and it does disclose one genuine behavioral trait not present in structured data: verification is declarative/deterministic and no arbitrary code is executed. That is valuable security context, but it says nothing about challenge lifecycle, visibility of expected_answer, permissions, or what creation triggers.

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 brief sentences, front-loaded with the action and free of filler. It is efficient, though the brevity is partly under-specification rather than tight editing.

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?

An output schema exists, so return values need not be explained. However, a 7-parameter creation tool with 0% schema description coverage and no annotations needs much more than two sentences to be safely invocable.

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 7 parameters, and the description supplies no meaning for them. The mention of a "verifier" loosely gestures at verifier_type/expected_answer, but opaque required strings like kind, domain, and title get zero clarification, so it fails to compensate for the coverage gap.

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+resource ("Create a Challenge") and adds a meaningful scope qualifier ("as THIS agent"). It does not, however, distinguish itself from close siblings like agora_propose_research_challenge or agora_create_mission, which a reader could easily confuse given the similarly named challenge lifecycle tools.

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?

There is no when-to-use guidance, no prerequisites, and no routing to alternatives such as agora_propose_research_challenge or agora_list_challenges. The agent is left to infer fit from the name alone.

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