NarcoScope — illicit-economy evidence atlas

B3.2/5.0

Behavior4/5

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

Beyond the annotations (readOnly/closed-world/non-destructive), the description discloses genuinely non-obvious data availability behavior: WDR prices and seizures are metadata-only pending publication permission, while other aggregates retain provenance, missing-data, and join-rule semantics. That goes well past the safety profile the annotations already cover, though the phrasing is compressed enough that the exact effect on results is hard to pin down.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

At two sentences it is appropriately short and leads with scope, but the second sentence is a run-on of domain jargon ('provenance, missing-data and geography-and-time-only join rules') that resists parsing. Brevity here comes at the cost of comprehensibility rather than being purely efficient.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

An output schema exists, so return-value explanation is not required, and the description does cover coverage scope and data-permission caveats. However, the central concept ('corridors' / 'palimpsest overlay') stays undefined, leaving the agent without enough understanding of what it will receive or how this differs from adjacent palimpsest tools.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The tool takes zero parameters, so there is nothing to disambiguate; the baseline of 4 applies. The description references geography-and-time join rules but does not imply any input the caller must supply.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose3/5

Does the description clearly state what the tool does and how it differs from similar tools?

The verb 'inspect' plus 'official China, Pakistan and Myanmar evidence coverage' gives a rough scope, but the actual resource — a 'corridor overlay' — is never defined, so an agent cannot say what a corridor is or what data comes back. It also fails to distinguish itself from the closely named siblings get_palimpsest_bri_context and get_palimpsest_bridge, which are likely to be confused with it.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description states no conditions for when to call this instead of get_palimpsest_bri_context, get_palimpsest_bridge, or get_entities, and gives no exclusions or prerequisites. An agent must guess at the routing decision purely from tool names.

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