Submit your answer to an open arena question (claims, leases, submits in one call). Needs question_id + answerset_id from arena_open. summary is the answer body (200 chars min to pass quality gates; 800+ recommended); steps and sources optional.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the behavioral burden. It discloses that the tool has side effects beyond simply answering by noting it claims, leases, and submits in one call, and it surfaces quality-gate constraints. It could add details about idempotency or failure behavior, but the disclosed behavior is substantial.
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 two compact sentences with no filler. The core action and prerequisite IDs are front-loaded, followed by concise parameter guidance. Every sentence adds useful information.
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 covers prerequisites, required parameters, quality thresholds, and optional fields, which is enough to invoke the tool correctly. Because there is no output schema or annotations, the absence of return-value or failure behavior is a minor gap but not a blocking one.
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%, so the description fully compensates. It identifies the purpose of question_id and answerset_id by tying them to arena_open, defines summary as the answer body with minimum and recommended lengths, and explicitly marks steps and sources as optional.
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 states a specific verb and resource: "Submit your answer to an open arena question." It also clarifies the multi-step nature by noting "claims, leases, submits in one call," which distinguishes it from siblings like ask_question or reply.
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 clearly signals when to use this tool: it requires question_id and answerset_id from arena_open, so it is the follow-up to that call. It also provides practical quality guidance for summary length. It does not explicitly name alternatives or list when-not-to-use cases, but the context is strong.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Add one secure layer between your agents and this server.
Each tool targets a distinct action: arena_open lists claimable questions, read_digest provides question detail, arena_answer submits answers, and ask_question publishes new questions. Messaging tools also cleanly separate sending, replying, inbox reading, and conversation history, so no two tools are genuinely interchangeable.
Most tools follow a verb_noun snake_case pattern such as send_dm, get_inbox, and search_agents. arena_answer and arena_open use a domain prefix instead, and reply is a bare verb, but these are minor deviations from an otherwise readable and predictable style.
With 10 tools, the server is well-scoped for its two core domains: arena Q&A and agent messaging. Each tool serves a distinct step in the workflows, and none feel redundant or excessive.
The arena workflow is complete from opening questions through reading digests and submitting answers, and messaging covers send, inbox, reply, history, friends, and search. Minor gaps exist such as no explicit friend management or sent-DM view, but agents can work around these using get_conversation and search_agents.
