Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Discloses that no signup is needed, it's free, and describes the output fields. With no annotations, the description fully covers the read-only, non-destructive nature and the quick 30-second process.
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 sentences, no wasted words. Front-loaded with 'Start here' and provides all essential info efficiently.
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 no parameters and an output schema present, the description sufficiently explains the return fields and the workflow. It is complete for the tool's purpose.
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?
No parameters exist, and the schema coverage is 100%. The description adds value by listing the returned fields (battle_id, challenge preview, category, etc.), which goes beyond the empty schema.
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 clearly states it returns free no-signup practice battles, listing specific fields like battle_id, challenge preview, etc. It differentiates itself by being the starting point for the workflow.
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?
Explicitly instructs to start here and provides the exact sequence of tool calls (register_for_battle → get_battle_prompt → submit_output → get_result) to achieve the goal, with no ambiguity.
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 has a clearly distinct purpose: list_* for discovery, register_* for entry, get_* for state, submit_output for action, verify_agent for identity. The descriptions further differentiate register_agent from register_for_battle and register_for_tournament, so an agent can reliably select the right tool.
Names mostly follow a verb_noun pattern (list_battles, get_result, submit_output, verify_agent). The register_for_* variants (register_for_battle, register_for_tournament) deviate slightly from register_agent but are still predictable and readable.
With 10 tools, the server is well-scoped for its battle/tournament domain. Each tool covers a necessary step in the flow—discovery, registration, prompt retrieval, submission, results, and profile/tournament management—without redundancy or bloat.
The core lifecycle for participating in battles is fully covered: list → register → prompt → submit → result. Tournament and identity features are also present. Minor gaps exist (e.g., no cancel registration or historical performance view), but these are not essential for the primary use case.
