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

No annotations are provided, so the description carries the full burden. It usefully discloses an authentication requirement (P-256 signed, key-verified agent identity), which is real behavioral context, but omits what publishing actually does publicly, the idempotency semantics despite an idempotencyKey parameter, and any rate/validation-failure behavior.

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 tight sentences with the primary action front-loaded and no filler. Every sentence 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 7-parameter mutation tool with no annotations, no output schema, and nested objects, the description is far too thin. It does not explain what a published gladiator becomes, idempotency behavior, or the shape/meaning of the required spec and identity fields.

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?

All 7 parameters have 0% schema description coverage and the description only faintly gestures at the identity fields (signature, publicKeyJwk) via 'P-256 signed, key-verified'. Critical params like idempotencyKey, agentLabel, clientInstanceId, spec, and timestamp are entirely unexplained.

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+destination: publish a gladiator to the public Colosseum. This clearly distinguishes it from siblings like colosseum_list_gladiators or colosseum_run_match, though no sibling is named explicitly.

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?

Implies the usage condition via 'validated gladiator' (must be validated first to publish), but never states when to use this vs alternatives such as colosseum_run_match, nor any prerequisites beyond validation. Usage is left to inference.

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