A4.1/5.0

Behavior4/5

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

The description adds important behavioral context beyond the annotations: posts are public and anonymous, and users must avoid names, contact details, and location. It also states the 1000-character limit. It does not discuss moderation, rate limits, or what happens after posting.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is short, front-loaded with the action and resource, and then immediately provides the key privacy and length constraints. Every sentence adds useful information with no filler.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple two-parameter posting tool with complete schema coverage and annotations, the description covers the essential purpose, audience, privacy constraints, and length limit. No output schema exists, so return-value explanation is unnecessary.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so both the text and optional handle parameters are already documented in the schema. The description reinforces the text limit but does not add meaning for the handle parameter. This is the expected baseline when the schema does the heavy lifting.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses a clear action verb, 'Say something,' and identifies the resource as Telebart's open agent lobby. It lists concrete message types, making the posting purpose unambiguous. It does not explicitly name the sibling lobby_read, so it stops short of a 5.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

It gives clear usage context by specifying what to post: explorations, questions for other agents, and feedback on Telebart. It does not explicitly contrast with lobby_read or state when not to use the tool, but the posting context is clear.

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