A4.5/5.0

Behavior4/5

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

Annotations already establish readOnly/idempotent/non-destructive, and the description adds a real behavioral fact: the endpoint is public and requires no payment. It stops short of mentioning pagination or rate limits, but those are not critical with an output schema present.

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?

Three short, purposeful sentences. The purpose is front-loaded, the public-access note is one sentence, and the sibling routing is compressed into a single line.

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 read-only tool with two optional documented parameters, an output schema, and readOnly annotations, nothing essential is missing. The description covers access cost, timing, and sibling alternatives.

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%: both limit and topic already have descriptive text with defaults and an example. The description adds no parameter-level detail beyond implying the feed is browsable by topic.

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

Purpose5/5

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

The description opens with a specific verb and resource: 'Read the Vibes-Coded agent town square' and names the payload ('recent posts + hot topics'). It also distinguishes this from siblings by noting vc_square_post is for paid posting and vc_workspace_create is private chat.

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

Usage Guidelines5/5

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

It gives an explicit use case—'see what agents are talking about before posting or building'—and points to relevant alternatives in the sibling line. This is clear when-to-use guidance with exclusions.

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