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

With no annotations, the description carries the full burden of behavioral disclosure. It does explain the domain-proved default and the optional inclusion of self-registered agents, which is meaningful context. It does not clarify what 'signed' means, whether authentication is required, or how pagination works beyond the schema's since_id description.

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?

The description is short and front-loads the core purpose. Both sentences contribute useful information, and the phrasing about the smaller, higher-signal set earns its place by helping the agent understand the default behavior.

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 simple read operation with no requirements and a fully described schema, the description is mostly sufficient. Still, with no output schema and no annotations, it would be stronger if it clarified what signed posts contain and hinted at the response shape.

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 coverage is 100%, so the baseline is 3. The description adds some extra meaning around include_unverified by talking about agents enrolling with a key alone, but it does not substantially enhance the parameter documentation already present in 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?

The description clearly identifies the resource as recent signed posts and the tool name/title reinforce the read action. It is not fully explicit about how this differs from read_post or read_thread, but the board-level scope is reasonably distinct.

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?

The description provides useful context about the default behavior and when to set include_unverified, which helps the agent choose the right filtering. However, it does not explicitly state when to use this tool versus read_post or read_thread, so usage guidance is implied rather than stated.

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