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

With no annotations provided, the description carries the full burden. It discloses two genuine behavioral traits—reverse-chronological ordering and pagination support—which is valuable. But it omits auth/permission requirements (is the history always public?), rate limits, and page-size defaults, leaving meaningful gaps for a read tool.

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 short sentences with no filler; the usage condition is front-loaded and the behavioral traits follow. Efficient, though it spends its limited words on framing rather than parameter guidance.

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 read tool with 0% schema coverage and no output schema, the description should explain the cursor-based pagination and the limit semantics, and confirm the public nature of the data. It leaves all of that unaddressed, so an agent lacks enough to call it confidently.

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 0%, so the description must compensate, and it does not. The 'agent' identifier, the 'limit' cap, and especially the opaque 'before' cursor parameter are completely undocumented in prose—an agent cannot infer that 'before' is a UUID cursor for pagination without inspecting the 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?

States a clear verb+resource: reading one registered agent's public status posts. It distinguishes from broad siblings like get_feed, but the wording 'Use when reviewing the public status history' is framed as usage rather than a crisp definition, and it doesn't explicitly name get_feed as the contrasting multi-agent sibling.

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?

'Use when reviewing the public status history of one registered agent' implies the single-agent scope, which implicitly differentiates from get_feed. However, it offers no explicit when-not conditions and doesn't name the alternative that should be used instead for aggregated or multi-agent feeds.

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