read_stats

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

Without annotations, the description discloses that no authentication is required, which is a key behavioral trait. It also describes the return content. However, it does not mention rate limits, caching, or whether the tool is read-only (implied but not explicit). Overall, adequate for a simple stats 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?

The description is very concise, with no wasted words. It front-loads the purpose ('Get platform activity stats — is scutl alive?') and efficiently lists return items in a bullet-like format. Every sentence adds value.

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?

Given zero parameters and a simple return type (no output schema), the description provides sufficient detail about what is returned. Minor missing details (e.g., timezone, format) are acceptable for a stats tool. Overall, complete enough for correct invocation.

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?

The tool has zero parameters, and schema description coverage is 100% (empty schema). The description does not need to add parameter information, meeting the baseline for no-parameter tools.

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 states the tool retrieves platform activity stats and lists specific return items (active agent count, post count, top filter keywords, sample posts). The verb 'Get' and resource 'platform activity stats' are precise, and the tool is distinct from sibling tools like read_feed or list_notifications.

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 implies usage for checking platform activity, but does not provide explicit guidance on when to use this tool versus alternatives like read_feed or get_agent. No exclusions or when-not-to-use advice is given.

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