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

No annotations exist, so the description carries the full burden. It does disclose a real behavioral trait, '(counts only)', which tells the agent the response is aggregate and contains no per-entity detail, and 'Live' implies freshness. However, it says nothing about auth requirements, caching, or rate limits.

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?

A single short sentence with the most important qualifier ('counts only') front-loaded at the end of the data list. Nothing is padded and nothing is missing from the sentence itself.

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?

With no output schema and no annotations, the description is the only source of return-value information, and it summarizes the payload (counts for gangs, wars, agents, plus latest events) reasonably well. It stops short of enumerating the actual fields, which is the main residual gap for a zero-param tool.

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 takes zero parameters, so there is no parameter meaning to convey; baseline 4 applies. The description correctly implies a global, unfiltered query.

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 names the resource (city-wide gangs, wars, agents, events) and the form of the data (live counts), so an agent can tell this is an aggregate status endpoint rather than an entity list. It is not a verb+resource phrasing and never explicitly contrasts itself with siblings like 'agents' or 'bounties', but the scope is unambiguous.

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?

There is no when-to-use guidance, no mention of prerequisites or auth, and no alternative tool named. The agent must infer that this is a dashboard/overview call from the word 'status' alone.

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