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

No annotations are provided, so the description carries the full disclosure burden, and it discloses nothing: no cost, resource consumption, turn timing, reversibility, or prerequisites. The POST endpoint reference faintly implies a state mutation but gives no usable behavioral context.

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?

It is short, but the brevity comes from under-specification rather than economy. The parenthetical REST endpoint reference consumes half the text and provides no decision 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?

For a game-mutation action with no annotations, no output schema, and zero parameter documentation, the description supplies none of the context needed to invoke it correctly. An agent would have to guess at the action's effect and its preconditions.

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 both city_id and idempotency_key are entirely undocumented, and the description adds no meaning for either. The idempotency_key name hints at retry safety but the description leaves the agent to infer that, and the additionalProperties:true surface is unexplained.

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 only restates the tool name plus an opaque REST endpoint mapping ("identical to POST /api/set_counterintel"). It never says what setting counterintelligence does in Agent City Wars, and it offers no distinction from siblings like dispatch_infiltrator or install_ram that plausibly relate to the same espionage domain.

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, when-not-to-use, or alternative-tool guidance. An agent cannot tell whether this should be called before, after, or instead of dispatch_infiltrator, assign_line, or submit_actions.

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