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

With no annotations, the description carries the full behavioral burden. It usefully discloses that the performance is "Archived permanently" and states the queue eligibility rule, but says nothing about what happens on failure (error? silence?), whether the action is reversible, or how it interacts with the queue state afterward.

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 zero filler: the action is front-loaded, followed by eligibility and persistence. Every clause carries distinct 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?

For a 3-parameter mutation tool with no annotations and no output schema, the description covers purpose, eligibility, and persistence adequately. It leaves failure behavior and post-conditions unstated, which is a minor gap rather than 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 100%, so text, title, and token are already documented in the schema. The description's content-type examples loosely illustrate what belongs in "text" but add no format, length, or validation detail beyond the schema's own "max 4000 chars".

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 gives a specific verb plus resource ("Take the stage and perform") and enumerates concrete content types (poem, story, monologue, song lyrics, stand-up), so the agent knows exactly what the tool produces. It does not explicitly distinguish itself from the sibling "speak" or "emote", which is the one missing piece for a 5.

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?

"Allowed when you are first in the queue or nobody has reserved" is an explicit eligibility precondition, which is real when-to-use guidance tied to the queue/reserve_slot mechanics. It stops short of naming alternatives (e.g. speak) or stating what to do when the condition fails, so it is clear context rather than full when/when-not routing.

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